Saied The admission of a child with congenital heart disease to the PICU after heart surgery is a uniquely stressful situation for both children and their parents and may impact how parents adjust to this situation. The purpose of this study was to explore the relationship between family and child demographic characteristics, stress, coping, social support and adjustment in families who have a child in the PICU after heart surgery. The study design was a non-experimental, descriptive correlational design. McCubbin and McCubbin’s Resiliency Model of Family Stress, Adjustment and Adaptation provided an organizing framework for the study. A convenience sample of 74 families (8 fathers, 66 mothers) participated in this study. Data were collected using a self-administrated questionnaire in two PICU hospitals in Cleveland, Ohio. Data were analyzed using descriptive statistics, Pearson r product-moment correlation, and simultaneous and hierarchical regression. Instruments used included a modified version of the Family Inventory of Life Events (FILE), the Parental Stressor Scale: PICU, Coping Health Inventory for Parents (CHIP), Inventory of Socially Supportive Behaviors (ISSB), and McMaster’s Family Assessment Device: FAD General Family Functioning and FAD Communication subscales. xiii Stress due to the accumulation of intra-family strain and stressful family life events was significantly correlated with FAD general family functioning and FAD communication. Both fathers and mothers reported that the overall PICU experience was stressful for them and rated the parental role and the child’s behaviors and emotions as the most stressful dimension of their PICU experience. The participants in this study used the three coping patterns of CHIP in different degrees to cope with their situation. Coping pattern Ι was used more often as compared to the other two patterns. Based on regression analysis, only pattern I coping made the most significant contribution to predicting general family functioning. Controlling for the parent’s age, gender, marital status, prior surgery and the child’s age increased the explained variance to 46% on the FAD general functioning and to 33% on the FAD communication. Social support did not predict family adjustment in this study, but it worked as a moderator variable between intra-family strain, stressful family life events and FAD general family functioning. More family-based research is needed to study stress, coping, social support and adjustment in families faced with other chronic illnesses of childhood as well as CHD. xiv 1 CHAPTER Ι Introduction Children are the jewels in their parents’ lives. When parents are informed that their child has congenital heart disease (CHD) even before the child is born, the joy of giving birth is often coupled with fear, guilt, sadness, shame, and blame because of the loss of the desired healthy child they had dreamed of (Cohn, 1996; Purcell, 1996). Many parents react to the initial diagnosis of their child’s CHD with a lack of acceptance or by denying that there is a problem (Canam, 1993; Lubinsky, 1994; Rosenthal, Biesecker & Biescker, 2001). Parents may also experience intense anger at the unfairness of the situation, or they may feel socially isolated and stigmatized (Rosenthal et al., 2001). Congenital heart disease (CHD) is a major health problem facing families in the United States today. It is estimated that in at least eight of every 1,000 live births, or about 25,000 to 35,000 babies are born with CHD each year in the United States of America (USA); that’s almost one percent of all live-born infants, and it accounts for approximately 30% of all congenital abnormalities (American Heart Association, 2006). The economic burden of caring for children with CHD is significant (Bristow, 1995). The direct medical expenses associated with this problem account for more than $87 billion dollars annually. Management of CHD is primarily surgical. Pediatric cardiac surgery began in 1939 with the ligation of a patent ductus arteriosus (Green, 2004; Waldhausen, 1997). The extraordinary advances in the field of pediatric cardiovascular surgery, improved diagnostic capabilities, and intensive care management over the past three decades have been successful in reducing mortality and providing infants and children with complete 2 repairs at earlier ages (Boneva, Botto, Moore & Yang et al, 2001; Soetenga & Mussatto, 2004). Cardiovascular surgery is performed through either a closed-heart or an open-heart approach. Open procedures employ the use of a heart/lung machine. The heart/lung machine is used to supply oxygen to the blood and pumps the blood through the body, bypassing the lungs and heart (American Heart Association, 2006). With the advancement of medical science and specialized surgical procedures, most children with congenital heart disease will experience one or more hospitalizations for surgical treatment or correction of their heart defects. Almost all of these children are admitted postoperatively to a pediatric intensive care unit (PICU) because they require immediate stabilization and life support, which is invasive, and which affects the appearance of the child (Lewandowski, 1980; Saenz, Beebe & Triplett, 1999). Complex monitoring systems, life support machines, and computerized infusion devices are used, and these machines emit strange lights and sounds, and they produce heat and can also make older children feel as if they are unable to move (Noyes, 1998, Synder, 2001, 2004). Moreover, the environment is usually bright and filled with unfamiliar people who are using language that is unfamiliar to the child, and who examine the child and perform uncomfortable and sometimes painful procedures (Synder, 2004). Parents are also worried about the child’s future and the responsibility of managing the child’s complex needs (Rosenthal, et al., 2001; Youngblut, Brooten & Kuluz, 2005). These factors often combine to create even greater stress for the parents because their child appears even more vulnerable, and parents feel helpless to change the situation or speed up their child’s recovery. 3 Nevertheless, this highly technical specialized surgery and postoperative care significantly reduce mortality and morbidity rates, and, in most cases, heart surgery in children has become a relatively routine procedure (Boneva, et al., 2001; Purcell, 1996; Soetenga & Mussatto, 2004). For parents, however, surgery on an organ as vital to life as the heart is never routine (Lewandowski, 1980; Utens, Bieman, & Verhulst et al., 2000). The prospect of cardiac surgery and admission to a PICU can be a uniquely stressful situation for both children and their parents (Bousso & Angelo, 2003; Purcell, 1996; Utens et al., 2000). Poor maternal adjustment, high levels of distress manifested as anxiety, sleeplessness, and social dysfunction of mothers of CHD children waiting for cardiac surgery have been reported by Utens et al. (2000) and Wray and Sensky (2004) prior to the scheduled surgery. In addition to their concerns over subjecting their child to a potentially life-threatening operation and thinking about possible complications, many parents also experience guilt, wondering if they are somehow responsible for their child’s heart defect (Purcell, 1996). When a child undergoes heart surgery, some parents are able to cope effectively, keeping their family together and dealing with these stressful times successfully. However, the stress associated with a child’s cardiac defect and surgery can devastate some families, as the pile-up stressors outstrip the family’s resources (McCubbin & Patterson, 1983). This special population and their families have different medical, developmental, social, emotional, and environmental needs and issues that require long term health care (Grey & Sullivan-Bolyai, 1999). 4 Significance of the Problem Investigators have examined the stress experienced by parents of children hospitalized in the PICU by focusing on the needs of those parents (Farrell & Frost, 1992; Fisher, 1994; Kasper & Nyamathi, 1988; Kirschbaum, 1990; Wray & Maynard, 2006), the actual stressors that parents experience (Berenbaum & Hatcher, 1991; Curley, 1988; Eberly, Miles, Carter, et al., 1985; Haines, Perger, & Nagy, 1995; Goldberg, Morris, Simmons, et al., 1990; LaMontagane & Pawlak, 1990; Lewandowski, 1980; Miles, Carter, Eberly, et al., 1989; Miles & Carter, 1982, 1983, 1985), the parents’ reactions and concerns (Youngblut, Brooten & Kuluz, 2005), and also by focusing on parental role alteration (Board, 2004; McCubbin, et al.,1989; Johnson et al.,1995). Numerous studies and conceptual frameworks have been identified in the literature that describe the possible causes and contributing factors of parental stress when a child is admitted to the PICU; however, research addressing the impact of the PICU on parents of CHD children after heart surgery is very limited. With the exception of three studies (Goldberg, Simmons, Newman, et al., 1991; Lewandowski, 1980; Miles, et al., 1989) the stress experiences of parents caring specifically for children with CHD after cardiac surgery has been ignored. Lewandowski (1980) was one of the earliest researchers who studied parents of children in a PICU who had undergone open heart surgery, and she identified several parental stressors, including unfamiliar machinery noise, changes in the child’s appearance, lack of privacy, and the disrupted sleep and eating patterns experienced by parents of children in a PICU. Miles et al. (1989) evaluated the stress levels of 179 parents whose children were admitted to the pediatric intensive care unit following heart surgery. The researchers 5 found that a major stressor for these parents is the alteration of their parental role, which means that the parents are stressed because they may no longer be able to do things that are considered essential to the basic foundation of being parents (Miles et al., 1989). Also, Goldberg et al. (1991) compared parenting stress among parents of infants with cystic fibrosis, those with congenital heart disease, and those with healthy babies. The results of this study revealed that the parents of chronically ill children consistently experience more stress than those of healthy children, and also that congenital heart disease in an infant is more stressful for parents than cystic fibrosis. They concluded that in this population of chronically ill infants, parental stress changes over time and is affected by the nature and course of the illness. Although these studies have contributed to our understanding of parenting stress in the PICU, several gaps remain in the research literature; one of these gaps is that most of the prior research done on PICU has focused on the immediate stressors associated with the child’s admission to the PICU (Miles, et al., 1989). But studies have indicated the importance of assessing other stressors occurring in the family prior to the child’s admission to the PICU (Leske and Jiricka, 1998), for these additional stressors influence parents’ level of stress, and how they cope and adjust to the situation. Another gap in the existing research literature is the small body of research related to the coping of parents of children who have undergone heart surgery. The first reported study came from the work of Lewandowski (1980), which identified six general coping styles used by parents of children who had open heart surgery: (1) initial immobilization (delay in approaching the child to reduce the impact of the situation); (2) visual survey (observe and became familiar with the environment before focusing on the 6 child); (3) withdrawal (removed themselves and avoided talking about or with the child); (4) restructuring (focused on one manageable aspect to regain parental mastery of the child’s care); (5) assistance (learned how to perform routine medical procedures); and (6) intellectualization (focused on technological issues and procedures). The author emphasized the importance of further research into parental coping. Miles and Carter (1983) have provided a theoretical paper that describes how Lazarus’ model of coping could be related to parental coping in the PICU. They developed a tool to measure the coping strategies used by parents in the PICU and staff behaviors that were rated as helpful by parents. This study had a small sample size, and was not focused on parents of children who had undergone cardiac surgery, and therefore may not represent a complete picture of coping strategies utilized by parents of such children. Furthermore, theoretical and empirical evidence supports the role of social support in influencing parents’ abilities to cope and adjust to stressful situations (Carey, et al., 2002; Katz, 2002; Tak & McCubbin, 2002; Visconti, 2000). Interest in factors that influence a family’s ability to adjust with stressful situations, like cardiac surgery and the admission of a child to PICU, has largely focused on the personal characteristics of family members, maternal uncertainty, the structure and function of the family, the severity of the child’s illness, and the amount of existing stress within the family (Tomlinson, Kirchbaum, Harbaugh & Anderson, 1996; Unger & Powell, 1980). However, resources outside of the family may be equally important in managing a stressful situation (McCubbin & Patterson, 1983; McCubbin et al, 1996). Nevertheless, no studies have been done to investigate social support in parents of children with cardiac 7 disease who were admitted to the PICU following heart surgery. So there is a need to further our understanding of this important concept as it relates to these populations. In addition, adjustment is crucial for parents of children in the PICU because their behavior will affect their child’s behavior (Brannan, Heflinfer & Foster, 2000; Melnyk, Feinstein, Moldenhouer & Small (2001); Melnyk, Small & Garno, 2004). Parents who have high stress levels and problems in adjustment, will often influence their children who are admitted to the PICU, and they too will have problems in adjustment. The literature indicated that children who are admitted to the PICU, such as children with CHD, are at greater risk of experiencing negative behavioral, emotional, and academic outcomes than those hospitalized in general pediatric units (Goldberg, et al., 1997; Griffin, Elkin, & Smith, 2003; Jones, Fiser & Livingston, 1992; Melnyk, et al., 2004). Moreover, Brannan, Heflinger & Foster (2003), and Schulz and Williamson (1991) found that if parents become depressed from the strain and stress of caregiving, then their own health will be impaired, with the possible consequences of unemployment, child neglect or abuse, and / or marital distress or termination. Thus, providing care to a child with congenital heart disease could negatively affect the parents’ as well as the children’s physical and mental health, resulting in additional increased health care costs (Brannan et al., 2003). In addition, the literature reveals other gaps in understanding the experiences of parents caring for children with CHD. Most of the prior research done in PICUs focused on mothers’ experience. There is a relative dearth of information regarding gender differences and stress. Although a person’s gender is one characteristic that may affect the way a stressful stimulus is perceived or reported, most previous studies of parental 8 stress have focused on stressful stimuli only as they affect mothers, and they have excluded fathers’ perspectives (Graves & Ware, 1990; Loucine, Huckaby & Kessler, 1999). But, by asking only mothers to report their experiences, only their description of the experience is obtained. This gap limits the validity of research findings with respect to the view of the family as a unit. In summary, research on family stress, coping, support and adjustment during a child’s hospitalization in the PICU after cardiac surgery is limited. Most of the previous studies included children with a variety of illnesses ignoring possible differences across illnesses with conflicting results and methodological problems. Nursing as a Discipline and Meta-Paradigm According to Schwab (1964), a discipline has both conceptual and syntactical structures. The conceptual structure of a discipline, which is composed of borrowed or invented conceptualizations, is determined by the perspectives of the discipline. The syntactical structure is the patterns of discovering truth and how “truth” is verified. Donaldson and Crowley (1978) mentioned that nursing is a discipline. As nursing is a professional discipline, four prominent concepts have been identified representing a nursing meta-paradigm: person, environment, nursing, and health (Fawcett, 1987/1984). Paradigms are systems of rules and regulations that create boundaries and direct behavior in order to ensure success (Baker, 1992). A nursing meta-paradigm provides a structure from which subject matter relevant to nursing may be described and/or selected for scientific attention (Kim, 1997). 9 A Person is defined as an open system interacting with the environment, family members, community, and other groups (Fawcett, 1980). A person is viewed as a human being who responds to nursing actions. Environment refers to the internal and external stimuli which can affect the development and behavior of persons or groups (Roy, 1984). Furthermore, environment has a comprehensive meaning of psychological, social, or cultural elements (Ellis, 1982). Health has a varied definition within the nursing discipline. Newman (1986) defined health as the client’s position on a continuum ranging from wellness to illness. The World Health Organization (1948) defined health as “a state of complete physical, mental, and social well-being and not merely [the] absence of disease or infirmity.” Nursing is the study of caring in the human experience (Newman, Sime, & CorcoranPerry, 1991). Although the conceptual model of this study is borrowed from another discipline – psychology – the relationships among the concepts of person, environment, health, and nursing fit well into the perspective of nursing and its meta-paradigm. Whall and Fawcett (1991) indicated that the Resiliency Model can be viewed within the context of the nursing meta-paradigm of person, environment, health and nursing. The relationship between the four central nursing concepts and the relevant concepts of this study are described as follows: (1) Person: The concept of person includes the parents of children having cardiac surgery. Additionally, as a person is a human-being; he/she is holistically viewed as composed of physical, biological, psychological, social, cultural, and spiritual units. 10 (2) Environment: Environment refers to the internal or external stimuli, including stress arising from the pile up of stressors, and stress that arises from the pediatric intensive care environment. These stimuli may lead to parental adjustment or maladjustment. (3) Health is viewed as a personal perception of family adjustment. (4) Nursing Nurses are the primary resource persons who provide information, education and support for parents who have a child who has undergone heart surgery. To help parents, nurses must assess their stressors, coping, and adjustment abilities. Nurses must also be aware of available resources for social support to be able to facilitate parents’ adjustment to their family’s situation. Purpose of the Study The purpose of this study is to explore the relationship between family and child demographic characteristics, stress, social support, coping, and adjustment in families who have a child in the PICU after heart surgery, using the resiliency model of family stress, adjustment and adaptation. 11 Research Questions Six research questions will be addressed by this study. Data analysis methods will include descriptive statistical analysis, correlation, and simple and multiple regression statistical analyses. The research questions and hypotheses are as follows: 1.What are the relationships among family and child demographic variables (the parent’s and child’s age, parent gender) and (a) stress; (b) coping; (c) social support; and (d) adjustment. 2. Do stress, coping, and social support affect the adjustment of families of children who have heart surgery? 3. What are the effects of stress, coping, and social support on family adjustment while controlling for the parent’s and the child’s demographic factors (parent’s age, gender, and child’s age)? 4. Does social support moderate the relationship between stress and adjustment in families of children in the PICU after heart surgery? 5. Does social support have a mediating effect on the relationship between stress and adaptation in families of children in the PICU after heart surgery? 6. What are the major sources of stress for mothers and fathers when their child is in the PICU following cardiac surgery? Theoretical Model The Resiliency Model of Family Stress, Adjustment, and Adaptation (McCubbin, Thompson, & McCubbin, 1996; McCubbin & McCubbin, 1993) will be used as the theoretical underpinning driving the conceptual model for this study. The Resiliency Model of Family Stress, Adjustments and Adaptation builds on three previous models: 12 the ABCX model (Hill, 1949), which examined the effect of pre-crises factors on the protection of families in crises after war separation and reunion; the Double ABCX model, which has been used to describe both pre-crises and post-crises factors that lead to adaptation in families which had a member missing in the Vietnam War (McCubbin & Patterson, 1983); and the Family Adjustment and Adaptation Response Model (FAAR) (Lavee, McCubbin, & Patterson, 1985), which focused on family efforts to balance demands and resources. The Resiliency Model was developed to explain why some families are more resilient than others and are better able to adjust and adapt to stress and crises. Resiliency is defined as the “positive behavioral patterns and functional competence individuals and the family unit demonstrate under stressful or adverse circumstances which determine the family’s ability to recover by maintaining its integrity as a unit while insuring, and where necessary, restoring, the well-being of family members and the family unit as a whole” (McCubbin & McCubbin, 1996, p5). There are two phases of the Resiliency Model: the adjustment and the adaptation phases. The adjustment phase of the model is considered the first response of the family to the illness stressors. The goal of the adjustment phase is for the family to manage the stressor by making short-term and minor changes in their ways of functioning. It consists of multiple factors such as pile-up of stressors, the family’s types and established patterns of functioning, the family’s appraisal of the stressor, problem solving, coping, and the family’s resources that interact following a stressor to support either good adjustment (bonadjustement) or poor adjustment (maladjustement). A family member’s brief acute illness with complete recovery is an example of a situation that may require only adjustment by the family (Friedman, Bowden & Jones, 2003). However, if the stressors 13 demand any major changes in family functioning and maladjustment occurs, then the family experiences a crisis situation and moves to the adaptation phase of the model (McCubbin & McCubbin, 1993). The adaptation phase of the resiliency model encompasses those families who have experienced maladjustment. During this phase, families must make necessary changes to patterns of functioning to deal with stressors. Family adaptation is described as the outcome of family efforts to achieve a new level of balance, harmony and functioning after a family crisis or stressful situation (McCubbin, et al., 1996). The strengths and capabilities that the family members share, such as family respect, support, hardiness, coherence and trust, can promote positive family adaptation (bonadaptation) through alteration of established patterns of functioning, expanding family resources, and developing new coping strategies (Friedman et al., 1998; McCubbin, et al., 1996). If bonadaptation does not occur, families move back into a crisis situation with maladaptation (Friedman et al, 1998; McCubbin et al, 1996). The adjustment phase of the Resiliency Model was the basis for this study, and factors involved with the adjustment phase that relate to this study are briefly discussed. This phase focuses on accumulation of stressors and strains, family coping abilities, and family resources which impact family adjustment. In the Resiliency Model, the idea of stressors is pressure placed on a family that can create changes in the way the family functions (McCubbin & McCubbin, 1993; McCubbin et al., 1996).When a family experiences a number of stressors and strains consecutively (i.e., a pileup of stressors, strains, and life transitions), it may become more vulnerable to stressors and successful 14 adjustment does not occur (Boss, 2002; McCubbin & McCubbin, 1993; McCubbin et al., 1996). Family resources include the abilities and characteristics that families have to help themselves manage the demands of the stressor and which help them successfully adjust and adapt to stressful life situations (McCubbin et al., 1996). This includes individual resources such as knowledge, experiences and personality, family resources such as economic stability and shared beliefs, community level resources such as the support that family can get from other family, friends and health care professionals (Friedman, Savarsdottier & McCubbin, 1998; McCubbin et al, 1996; Van Riper, 2001). Coping in the Resiliency Model refers to a specific cognitive and behavioral process by which individual members in the family or the family itself attempts to reduce or manage the excessive demands on the family through the realization that systemic changes are needed to re-establish functional stability and to manage the situation associated with the demand (Take & McCubbin, 2002; McCubbin, et al., 1996). Coping helps families to adjust and adapt to stressful situations through direct actions taken by the families to reduce stress, such as obtaining and finding additional resources that were not in the family, managing the tension by doing things together as a family, and maintaining an optimistic attitude toward the stressful situation (McCubbin, et al., 1996). Family adjustment in the Resiliency Model can be good (bonadjustment), which requires only minor changes in family functioning; or it may be poor (maladjustment), which precipitates a crisis (which is a continuous state of disorganization, disharmony, or imbalance in the family unit) and requires major changes in family functioning (Friedman et al., 1998; McCubbin et al., 1996). 15 Application of the Resiliency Model to this Study Although the Resiliency Model is relevant to a number of disciplines, its use in the nursing literature exceeds any other single model for studies relevant to the phenomena of acute and chronic family stress. In addition, the Resiliency Model can be viewed within the context of the nursing meta-paradigm of person, environment, health and nursing (Whall & Fawcett, 1991). Although the Resiliency Model has not been used specifically with regard to children in the PICU after heart surgery, the Resiliency Model or earlier versions of this model have been used in studies of parents of children in NICU (Pinelli, 1997), parents with CHD children (Tak & McCubbin, 2002; Savarsdottir & McCubbin, 1996) and parents of children with other chronic illnesses (LoBiondo-Wood, Bernier-Henn, & Williams, 1992). The conceptual framework for this study (p. 18) will be drawn from the first phase of the Resiliency Model, family adjustment. The concepts derived from the Resiliency Model are stress, social support, coping and family adjustment. The modifying factors used for this study are demographic variables. The demographic variables selected are the parent’s age, gender, and the child’s age. The adjustment phase of the model explains the family response to illness stressors which require only minor changes in functioning (Friedman, et al., 2003). Family adjustment, rather than adaptation, will be the focus of this study because data collection will take place during a period in which adjustment, rather than adaptation, would be the predominant outcome (24 after the surgery). A fundamental assumption of the Resiliency Model is that stressful adverse circumstances do not just affect one member of the family, but they influence the entire family system (Walsh, 2003). Having a child who is diagnosed with congenital heart 16 disease and admitted to the PICU after heart surgery not only affects the ill child, but it is a very stressful situation for all the family members, especially the parents (Carter & Miles, 1984; Elberly et al., 1985; Miles, 1979; Miles & Carter, 1983; Miles et al., 1985; Miles et al., 1984). When families are confronted with an illness stressor such as congenital heart disease, they need to adjust or adapt to the situation. The family’s life will most likely be temporarily or permanently affected due to the results of cardiac surgery and the PICU admission. According to the Resiliency Model, the goal of the adjustment phase is for the family to manage the stressor in the short term without introducing any major or lasting changes in the family’s established patterns of functioning, and this phase requires only minor changes in the family unit’s behavior. In cases where families have a child with congenital heart disease and that child has heart surgery, a family may require to change the way it functions and try to manage the illness-related stressors by introducing changes such as modifying the family’s routine, hiring someone outside the family to complete household tasks, or arranging for childcare for siblings at home or time off of work for the parents so they can be with their sick child. How the family adjusts to the PICU experience after heart surgery and whether their adjustment is successful or not depends on some variables such as the present stressors from the cardiac surgery and the PICU environment, the earlier stressors and strains that already exist, such as financial strain, navigating the health care system, the family’s past experience in the PICU, the support of family and friends, and the family’s coping strategies, as well as the parent’s (or parents’) gender(s), and the child’s age, along with many other variables (Curely, 1988; McCubbin & McCubbin, 1993; McCubbin et al, 1996; Philichi, 1989). The outcome may 17 be positive (bonadjustment), in which the family moves through the situation without any difficulties, or the outcome may be negative (maladjustment), in which the established patterns of functioning are disrupted and the result is a crisis situation for the family, where upon the family enters the second phase of the Resiliency Model. 18 Social Support Child’s age Parent’s/ age Parent’s gender) Family Adjustment Stress Coping Figure 1.

What has impact on one person in the family also affects the others to some degree. In this study, parents and children are understood as a whole system rather than simply as individuals. Definitions of Terms The conceptual and operational definitions for the study variables are as follows: Stress Conceptual definition. Stress is conceptualized as encompassing dimensions of environmental stress in the PICU (Miles, Carter, Hennessey, Eberly, & Riddle, 1989) and the stress arising from intra-family strain and negative family life events (McCubbin et al, 1996). Operational definition. 1-The rating of the Parental Stressor Scale: Pediatric Intensive Care Unit (PSS:PICU). 2-Accumulation of stressful family life events and intra-family strain that happened prior to the illness stressor, as perceived by the parents on the Family Inventory of Life Events (FILE) (McCubbin, 1983). 21 Coping Conceptual definition. Coping refers to strategies, patterns, and behaviors designed to maintain and/or strengthen the organization and stability of the family unit (Patterson & McCubbin, 1983). Operational definition. The rating of the Coping Health Inventory for Parents (CHIP). Social Support Conceptual definition. Social support refers to the activities directed at assisting others in mastering emotional distress, sharing tasks, giving advice, information, and providing material aid (Barrera, 1981; Caplan, 1976; Hirsch, 1980). Operational definition: The parents’ scores on the Inventory of Socially Supportive Behaviors (ISSB). Adjustment Conceptual definition. Adjustment defined as the parent’s perceptions of the family’s ability to maintain and perform family functions and effective communication in response to stressors. Operational definition. The parent’s ratings score on The General Functioning and Communication Subscales of the McMaster Family Assessment Device (Epstein, Baldwin, & Bishop, 1983) Parent’s Gender Conceptual definition. Gender consists of the gender of the parents. 22 Operational definition. Gender will be measured using a categorical rating of male or female status based on each subject’s response to a question regarding his or her gender. Parent’s Age Conceptual definition. The chronological age of the parents at the time of the study. Operational definition. The parents’ ages will be determined using the background information form as self reported by the parents. Age of the Child Conceptual definition: It is the chronological age of the child at the time of the study. Operational definition: The age of the child will be determined using the background information form as reported by the parents 23 CHAPTER ΙΙ Literature Review The key concepts around which this literature review is presented are congenital heart disease, stress, coping, social support and adjustment. The review will be organized into six sections. The first section of the literature review will be an introduction and an overview of congenital heart disease. The second section will provide an overview of the literature on stress. The third section will focus on coping. The fourth section will contain studies pertaining to social support. In the fifth section, studies related to adjustment will be presented. In the last section, studies related to the relationship among the study variables will be presented. The review demonstrates diversity of findings and the poverty of research with regard to the population of interest. Congenital Heart Disease A chronic health condition is one that is long-term and not curable, or which involves limitations in daily living requiring special assistance or adaptations in function (Stein, 1992; Tansella, 1995). Chronic diseases are one of the major health problems in the world including the USA. Chronic illness affects people of all age groups and has a great impact on individuals, families, and society at large. Chronic disease remains the primary cause of disability and contributes to the suffering and reduced quality of life of the afflicted and their families (Turner, 1998). In an analysis of the National Health Interview Survey on Child Health (NHIS-CH) Newacheck and Taylor (1992) found that 20 million American children under age 18 have one or more chronic conditions. Of these, two-thirds have mild cardiac defects with minimal activity limitations, and 5% have severe cardiac defects that persistently limit their activities. 24 Scope of the Problem Congenital heart disease is one of the most serious and most commonly occurring chronic illnesses in children (Grech & Elliott, 1998). Congenital heart disease involves structural, positional or functional abnormalities of the heart and/or related major blood vessels present at birth. It may be acyanotic or cyanotic, depending on whether nonoxygenated blood is present in the systemic circulation system (Friedman, 1999; Lilly, 1998; Porth, 2002). In the USA, CHD is the number one birth defect affecting approximately 25,000 to 30,000 children each year. At least eight of every 1,000 infants born each year display congenital heart disease, which is almost one percent of all liveborn infants (American Heart Association, 2006). The mortality rate of these children may be as high as fifty percent in the first year of life, depending on the condition (NIH Guide: Pediatric Disease Clinical Research Network, 2000; Hamed & Maher, 2000). As a result, the economic strain on the health care system that results from caring for CHD children is significant (Bristow, 1995; Rossiter & Callan, 1993). Because of the advancement of fetal imaging techniques since 1980, studies suggest that 30 to 60 percent of congenital heart defects can be discovered prenatally by fetal echocardiography (Allan, 1996; Gomez, 2003; Goncalves, et al., 2006; Stauffer & Murphy, 2002). Botto and Correa (2003); Bristow (1995) and Allan (1996) indicated that the exact etiology of CHD remains elusive in most cases; however, the incidence of CHD is higher when there is an interaction between some factors in pregnant woman and genetic susceptibilities. Women at risk of having a CHD child include those with a family history of CHD, those exposed to rubella during the first three months of pregnancy, those who are over 40, those with chronic illness such as insulin-dependent diabetes, 25 those who are heavy smokers and who drink a lot of alcohol, or those exposed to drugs such as indomethacin (Indocin) (Blincoe, 2005; Hobbs, 2006; Martinez, Sian, Klesinman, & Copel, 1996). Also, chromosomal abnormalities (e.g., Down syndrome) are related to the increased incidence of heart defects in children (Karmer, et al., 1987; Porth, 2002; Wong, 1987). The overall occurrence of CHD in the newborn sibling of an affected child is relatively higher than in the general population (Hamed & Maher, 2000). Both male and female children are affected equally (Hamed & Maher, 2000; Wong, 1987). One-third of infants born with CHD develop life-threatening symptoms within the first few days of life (Saenz, Beebe & Triplett, 1999). Clinical manifestations in infants are determined by the severity of the defect and the amount of pulmonary blood flow (Neff & Spray, 1996). General symptoms of congenital heart disease include dyspnea, tachypnea, growth retardation, decreased exercise tolerance and tissue hypoxia (Whaley & Wong, 1989). In addition, infants with CHD may show other symptoms such as fatigue, fatigue difficulties, hypotonia, pallor, sweating, infections, bleeding disorders, arrhythmias, and problems of growth and development and syncopal attack (Cook & Higgins, 2000; Whaley & Wong, 1989; Porth, 2002). Difficulty in feeding is reported by parents of CHD children and is often associated with tachypnea, sweating, and subcostal retraction (Lobo, 1992; Silove, 1994). CHD should be considered if feeding takes more than 30 minutes (Silove, 1994). Advances in the management of children with congenital heart disease has contributed to improvement in survival (Green, 2004; vanVught, Sreeram, Schroder, & Vries, 2000). Compared to the previous decade, the vast majority of children born with CHD who were not expected to survive to adulthood are now surviving (Dastgiri, 26 Gilmour & Stone, 2003; Tong et al., 1998; Sparacino et al., 1997). Progress in prenatal imaging techniques, surgical procedures, anesthesia, use of prostaglandin E, and a large number of therapeutic techniques have played a big role in this success (Armstrong, 1995; Jonas, 1995). Approximately 1 in 5,000 CHD children will require surgical correction of their heart defect(s) (Hoffman, 1990). Each newborn with a CHD must undergo a careful evaluation for any additional defects before surgery because a heart defect may be associated with other congenital defects (vanVught, Sreeram, Schroder & Vries, 2000) In summary, CHD is a major and serious childhood illness due to its high incidence, high mortality and the economic strains that it puts on the budget of both families and communities. Conceptualization of Stress Regardless of there being substantial literature on stress, there are still many issues regarding its conceptualiazation that remain unclear (Smith, 2003). Researchers have not come to a unified definition of the term. Kugelmann (1992) and Newton (1995) stated that the concept of stress traces back to ancient Greek texts, which refer to stress as a vague notion of ill health. Selye (1976, 1956) was the first theorist to become interested in linking stress with physical disease and ill health in human beings. Selye divided stress into bad stress and good stress. Good stress was referred to as eustress, and distress referred to bad stress (Selye, 1976). Selye’s work has encouraged a large number of other researchers to examine the concept of stress, thereby contributing to an increase in stress research in the second half of the twentieth century (Goldberger & Breznitz, 1982). Selye (1976) defined stress as a response or state of tension produced by the 27 stressor(s) or by the actual/perceived demand(s) that remain unmanaged. Hinkle (1974) described stress as a stimulus not a response as had been previously described by Selye. Hetherington (1984) added the two together (stimulus and response), and defined stress as a broad interactive network of factors that includes stimulus, response, characteristics of the individual, interpretation and appraisal of the event, and activation of the individual to modify or adapt to the situation. Although the definitions of stress are varied, most researchers agree that stress can be broadly defined as an individual’s response when the physical or psychosocial demands of a situation exceed the individual’s ability to adapt (Weinberg & Richardson, 1981). Family stress and CHD Two decades ago, children who were acutely or chronically ill, such as children with congenital heart disease, were cared for in hospitals and other institutions with limited parental visitation, and parents were often viewed as unqualified to provide care for their seriously ill children. Moreover, children with chronic illnesses rarely survived to adulthood. Today, advances in cardiovascular diagnostic and surgical techniques have reduced the mortality rates of these children. CHD children have experienced an almost doubling of their life expectancy (Nieminen et al., 2003). However, this increase in their survival rate has contributed not only to the chronicity of the illness but also to the stress that the families of these children face (Balluffi, et al., 2004; Hayes, Stainton, & McNeil, 1993; Turner, Tomlinson, Harbaugh, 1990). Boss (2000, p.16) defines family stress as pressure or tension in the family system – a disturbance in the steady state of the family. Cohen and Wills (1985) have pointed out that stress can be assumed to arise when one appraises an event (or combination of 28 events) as highly demanding and does not have suitable coping abilities to deal with it. Stress of families of children with CHD is ongoing, and this stress starts immediately after diagnosis. Parental responses to the diagnosis of their child’s chronic condition, including CHD, commonly include shock, disbelief, depression, frustration, denial, guilt, confusion and anger (Canam, 1993; Lubinsky, 1994; Rosenthal et al., 2001; Schrey & Schrey, 1994; Upham & Medoff-Cooper, 2005). Uncertainty regarding the child’s health condition and his or her possible outcomes, and difficulty in caregiving are major stressors at the time of diagnosis (Cohen, 1993; Cohen & Martinson, 1988; Wereszczak, Miles, & Holditch-Davis, 1997; Upham & Medoff-Cooper, 2005). Other stressors that the parents of children with chronic illness experience immediately after the child has been diagnosed with a chronic condition include their loss of the imagined healthy child that they dreamed of and also their fear of the possibility of the potential loss of their child (Bousso & Angelo, 2003; Cohen, 1993; Upham & Medoff-Cooper, 2005). Parents of children with CHD reported higher stress than parents of children with other chronic illnesses. Goldberg, Morris, Simmons, Fowler, & Levison (1990) conducted a prospective, longitudinal study to compare the responses of parents of infants with cystic fibrosis (CF), to those of parents whose children have congenital heart diseases, and parents of healthy infants. Interviews took place within two months of the diagnosis of the ill newborn. Parents of infants diagnosed with CHD reported more overall stress than parents of healthy children and parents of children with cystic fibrosis. Subsequently, Goldberg, Simmon, Newman, Campble, and Fowler (1991) reported on the effect of CHD on the early infant-mother relationship. Significantly fewer infants 29 with CHD, in comparison with healthy peers, were considered to have secure relationships with their mothers. Fathers’ experiences when they have a CHD child have been not well described in the literature. One of the few studies in this area was done by Clark and Miles (1999).The researchers explored the experience of fathers whose infants were newly diagnosed with severe CHD using a qualitative research design. Only 8 fathers participated in the study. The results indicated that fathers expressed different conflicting feelings regarding their children’s illness. Fathers expressed their first feelings of joy, excitement about being a father, and then that joy turned to sadness and distress after learning their child’s diagnosis. Then fathers started to become attached to the child and at the same time fear that they will lose their child at any time because of the unpredictable nature of their child’s disease. Fathers also expressed their attempts at hiding their feelings and emotions and trying to look strong and supportive in front of their sad wife despite their own emotional needs and distress. In addition, the stress of the family with a CHD child has been reported to continue to exist for months after surgical repair (Gardner, Freeman, Black, & Angelini, 1996; Rogers et al., 1984). In an investigation examining stress across time, mothers of infants undergoing heart surgery (heart surgery group) were compared to mothers of infants admitted to the hospital as non-surgical patients (inpatient group) and mothers of infants attending well-baby visits (outpatient) (Rogers et al., 1984). Questionnaires assessing maternal distress were completed by mothers of cardiac infants preoperatively, seven days postoperatively, and at 2 months post discharge and by mothers of the comparison groups at comparable points in time. The heart surgery group did not differ 30 from the outpatient group on the day of admission. However, the heart surgery group differed significantly from the outpatient group seven days post surgery, particularly in the amount of depression mothers were reporting. Although it was hypothesized that the three groups would not differ two months after the initial contact, the mothers of infants who underwent heart surgery two months earlier reported more distress relative to the other two groups. These results suggested that stress associated with having a child with CHD might continue to exist months after surgical repair of the lesion. Consistent with the findings by Rogers et al. (1984), the continuing stress of families who have children with CHD has been observed by other researchers. Gardner et al. (1996) compared 20 mothers of infants with CHD with 20 non-cardiac mothers. The results indicated that mothers of children with CHD were more distressed than the comparison group as measured by the General Health Questionnaire when tested two days before and six months after a corrective heart surgery. In addition, Gardner et al. (1996) also assessed the impact stress has on mother-infant interactions by observing cardiac infant-mother dyads and comparing them to non-cardiac infant-mother dyads, both prior to surgery and six months post-operatively Results from observing the motherchild interactions indicated that both cardiac infants and their mothers showed less positive affect and engagement than the comparison group at the pre-operative and postoperative observation sessions. Some mothers had difficulty adapting to their infants, leading to disordered interactions. Gardner et al. (1996) suggested that more attention, encouragement and support are needed for parents who have children with congenital heart disease. The sample studied by Gardner et al., however, was small, and consisted only of infants who had more serious congenital heart defects. 31 Also, Uzark and Jones (2003) investigated 80 parents (70 mothers and 10 fathers) with a child 2 years or older with CHD. These parents completed the Parenting Stress Index (PSI) short form (Abidin, 1990, 1995, 1986). The results indicated that parents of children older than two years reported excessive parenting stress than the normative population. Pelchat et al. (1999) studied stress among 144 Canadian parents in response to their 6-month-old infant’s type of illness. They compared three groups: parents of children with CHD, parents of children with a cleft lip and/or palate, parents of children with Down syndrome and parents of non-disabled children. The results indicated that parents of children with CHD and parents of children with Down syndrome reported significantly more stress than the control parents or parents of a child with a cleft lip and/or palate. Specifically, they reported more stress related to acceptance of their child, suggesting that a child with CHD has characteristics that do not match the expectations the parents had for their child. Difficulty in feeding their infant with CHD can affect the mother-infant relationship and lead to parental stress (Duhn, 1998; Lobo, 1992). Mothers of infants with CHD have reported difficulties in feeding (Lobo, 1992; Lobo & Michel, 1995), and feeding the infant can be the most time-consuming caregiving task (Svavarsdottir & McCubbin, 1996). A qualitative study (Duhn, 1998) was conducted in which the researcher interviewed and observed seven mother-baby dyads and found that mothers reported three identifiable and somewhat overlapping phases in their struggles to feed their infants for survival. These phases are (a) acknowledging (a mother’s recognition of the reality of her situation based on her observation of her infant’s behavior, measured 32 against her expectations of a healthy infant); (b) integrating feeding into daily life (mothers attempt to nourish their infants’ physical and emotional health and to build a confident relationship with their babies); and (c) developing feelings of control over feeding (mothers aware of the change in their infant’s feeding abilities and also a change in their response to the overall feeding experience). The study results are limited due to the small sample size (seven mothers), and because the mothers were frustrated both in terms of themselves and their babies. Parents’ stress related to the severity of the child’s cardiac condition was investigated by Morelisus, Lundh & Nelson (2002). The researchers assessed the differences in perceived stress between parents of children with a simple cardiac defect (ventricular septal defect) and parents of children with a complex cardiac defect (conduit). They measured stress using the Swedish version of the parenting Stress Index and the Swedish Parenthood Stress Questionnaire (SPSQ). The results indicated that there was no significant difference between the stress level reported by the two groups, and this might indicate that the presence of cardiac disease itself, rather than the complexity and severity of the defect, is the source of stress for parents. The previous literature implies that parents of cardiac infants report greater levels of stress compared to parents of non-cardiac infants. Family stress and PICU An additional stressor for the parents of a CHD child is the subsequent admission of the child to a pediatric intensive care unit (PICU) after heart surgery. The hospitalization of a child in a PICU is a uniquely stressful experience for both the child and the family (Board & Ryan-Wenger, 2000; Balluffi, et al., 2004). Mortality rates for 33 children in the pediatric intensive care unit (PICU) range from 5% to 6% (Fiser, 1992; Pollack, Cuerdon, & Getson, 1993), but 75.4% of the children survive with no impairment (Fiser, 1992). A number of studies are available on the stressors experienced by parents in an intensive care unit; however, little is known about the nature of parents’ stress surrounding a child’s admission to the PICU after heart surgery. Lewandowski (1980) was one of the earliest researchers who studied parents of children in a PICU after heart surgery, and she identified several parental stressors, including unfamiliar machinery noise, changes in the child’s appearance, lack of privacy, and the disrupted sleep and eating patterns experienced by parents of children in a PICU. Miles, Carter, Riddle, Hennessey, & Eberly (1989) evaluated the stress levels of 179 parents whose children were admitted to the pediatric intensive care unit following heart surgery. The researchers found that a major stressor for these parents is the alteration of their parental role, which means that the parents are stressed because they may no longer be able to do things that are considered essential to the basic foundation of being parents (Miles, Carter, Riddle et al., 1989). Perceived illness severity was the same for parents of cardiac children and parents of non-cardiac children at admission, but parents of cardiac children rated illness severity lower than other parents at the time of data collection (24 to 48 hours after admission). Higher total stressor scores were related to higher trait anxiety, lower parental age, higher perceived severity of illness, younger child age, more ICU visitation, and perception of inadequate pre-PICU preparation (Miles, et al., 1989). The research on families who have children with CHD admitted to the PICU after heart surgery is sparse, so other studies that look to parents’ stress experience in PICU 34 regardless of the child’s illness were examined. Carter, Miles and colleagues (Carter, Miles, Buford, & Hassanein, 1985; Eberly,et al, 1985; Miles, Carter, Spicher, & Hassanein, 1984) performed three major studies to describe parental stress during a child’s PICU admission due to different diagnoses (without looking to a certain diagnosis per se). They developed a conceptual model for understanding parental stress in the PICU. This model builds on the theories of Selye, Lazarus, Roy, and Moos. They also developed a scale that builds on their conceptual model: the Parental Stressor Scale Pediatric ICU. In general, researchers (Carter et al., 1985; Eberly et al., 1985; Miles et al., 1984) have suggested that the stress response expressed by parents of children in the PICU is the result of a complex interaction between a number of variables that include personal-family factors (e.g. parents’ educational level, age, other life stressors), situational variables (e.g. type of admission, perceived severity) and environmental stimuli (stimuli arising from the physical and psychosocial aspects of the PICU such as sights and sounds in the unit, procedures done to the child, the child’s appearance, the child’s behavior and emotional reaction, parental role alteration, staff communication and staff behavior). All of these factors interact as sources of stress for parents who have a child in the PICU. The results of these three studies (Carter et al., 1985; Eberly et al., 1985; Miles et al., 1984) consistently showed that the child’s behavior and emotions and alterations in the parental role were the most stressful dimensions for both fathers and mothers. In particular, items like not being able to protect my child and not knowing how to help my child, the child’s acting as if in pain, and seeing the child looking frightened were the most stressful items under these dimensions. Although this program of research has contributed to our understanding of stress in the PICU, the generalizability of the 35 findings is limited by the homogenous sample of parents surveyed because 85% percent of the parents who participated in the studies were Caucasian . Alteration in the parent-child interaction that occurs when the child is hospitalized in the PICU has been also investigated by Curley (1988). The researcher used a quasiexperimental design to assess the effect of a Nursing Mutual participation model of Care (NMPMC) on parental stress in the PICU. The participants were divided into two groups: the experimental group and control group. Parents in both study groups received usual nursing care from the PICU staff, and those in the experimental group also received the NMPMC intervention through daily contact with the researcher. Results of the study showed that families in the experimental group (16 parents) perceived less stress as compared to the control group (17 parents). The small sample size and lack of randomization may limit the generalizability of this study. Haines, Perger and Nagy (1995) compared the stress level of PICU parents whose children were intubated and parents whose children were not intubated. Researchers collected their data using PSS: PICU. Results of the study indicated that the most stressful PICU dimensions for parents were painful procedures, the sight and sounds of the PICU and child’s behavioral and emotional responses to the PICU. Parents of intubated children were more distressed by painful procedures conducted on their children than parents of non-intubated children. Psychometric analysis of the PSS: PICU was not reported for this study, and this is important since this study was conducted in Australia and the PSS: PICU was developed and tested with American populations only. 36 Summary The literature presented above points to the higher levels of stress that families of infants and children with congenital heart disease have at the time of diagnosis and during the course of the disease even after repair, and the effect this stress might have on the parent-child relationship. However, there are several problems with these studies. Only a few studies focused specifically on parents of children with CHD after heart surgery. Thus, the effects of the hospitalization of a child undergoing heart surgery on parents are still unknown. In addition, the timing of the data collection in the studies varied considerably, and therefore, since the stress level varies for specific stressors over time the results are confounded by the inconsistency in the time between the child’s admission to the PICU and data collection. Additionally, much of the analysis was not done independently for mothers and fathers although at times, more than one parent was sampled from each family. Also, most of the studies have a small a sample size that might affect the generalizability of the research findings. Furthermore, when a family has a child who is seriously and/or chronically ill as are children with CHD, they are rarely dealing with a single stressor. Cumulative life changes along the course of the illness have received little attention in the nursing literature. Research with tighter methodological controls is necessary to improve our understanding of what families of CHD children experience. Conceptualization of Coping Coping is a complex phenomenon that is difficult to understand (Take & McCubbin, 2002; Beutler, Moose, 2003). The study of coping started in the 1940’s and 50’s during World War II and the Korean War (Lazarus & Folkman, 1984). Although a 37 consensus has not yet been reached on a specific definition of coping, there is general agreement (Lazarus & Folkman, 1984; Pearlin & Schooler, 1978) that coping is defined as the constantly changing cognitive or intrapsychic and behavioral or action-oriented efforts developed to manage and minimize specific internal and external demands that are found to exceed the resources of the person. In the view of Friedman et al. (2003) coping is restricted to the actual behaviors or cognitions people utilize, not to the resources they might use. Folkman and Lazarus (1984); Monat & Lazarus (1991) explained that coping requires both thought and action, and an individual first appraises the stressor by identifying it and deciding whether it is threatening or challenging (primary appraisal). Following this interpretation, the individual decides whether the coping resources and options available are adequate to cope with the situation (secondary appraisal). McCubbin & McCubbin (1993) define family coping as an active process where the family utilizes existing family resources and develops new behaviors, responses and resources to strengthen the family and to decrease the influence of stressful life events. When shifting from the individual level of coping, family coping becomes hard to explain. Because of the difficulty in assessing family coping efforts, most family coping research describes a combination of individual and family coping responses utilized by the family members. The function of coping as described by McCubin et al. (1996) and Danielson, Hamel-Bissell & Winstead-Fry (1993) is to maintain and restore the balance between demands and resources, and at the same time to eliminate or decrease the intensity of the chronic and/or critical illness and its associated hardships. Positive family coping occurs 38 when the family succeeds in maintaining family equilibrium following an illness stressor. Coping is necessary for survival, and it determines how successfully the person will reduce the effects of stressors. McCubbin et al. (1984, 1996) stated that the family can use available resources from both the family and community to regulate the stressful situation. The family can use resources from within the family itself such as changing roles, sharing problems, and also from the community (e.g., social support from relatives and friends, neighbors, extended family, professional interventions). In addition, in order for families to have positive coping, families have to use their ability to redefine stressful events so they become more manageable; they must also accept problems and think how to deal with it, thereby minimizing their effects (McCubbin, 1985). Coping and CHD Although a considerable number of studies have been conducted on congenital heart disease in children, the coping strategies of their families were represented in only a small portion of these studies. Savarsdottir and McCubbin (1996) assessed parental coping behavior in 71 families of infants diagnosed at birth with CHD. Coping was measured by the Coping Health Inventory for Parents (CHIP) (McCubbin, McCubbin, Nevin, & Cauble, 1979). The CHIP consists of three subscales measuring three patterns of coping. Coping pattern I is composed of 19 behaviors that focus on family integration, cooperation, and an optimistic definition of the situation. Coping pattern II consists of 18 items labeled maintaining social support, self-esteem, and psychological stability. Coping pattern III contains eight behaviors designated as understanding the health care situation through communication with other parents and consultation with the health care team. These researchers found that mothers of infants with more severe CHD reported 39 developing more helpful coping behaviors related to understanding the health care situation, such as talking to the health care team and with other parents. In addition, there was no significant difference in the coping patterns of parents of later-born infants and first-time parents. Almost all the parents were white (98.6%) and middle-class, so the generalizability of the findings may be limited. Also, Tak & McCubbin (2002) used the Coping Health Inventory for Parents (CHIP) (McCubbin et al. 1979) to assess the coping patterns used by 92 families who had a child 12 years and under who was newly diagnosed with congenital heart decease. The findings indicated that mothers use coping patterns related to family integration, optimism, and medical communication, while fathers used coping patterns of maintaining social support, self-esteem and psychological stability. Family coping was studied in relation to children with other chronic illnesses. For example, Brazil and Krueger (2002), in their study of eighty-four parents (49 mothers and 35 fathers) who were primary caretakers of children with asthma, found that mothers reported a greater tendency than fathers to use coping patterns related to maintaining social support, self-esteem, and psychological stability. Similarly, McCaleb, and Luther (1996) used the CHIP to examine the coping patterns of 22 parents of children on home apnea monitoring. Parents reported that they use all three coping patterns to cope with their children’s illness. Powers (1986) found that mothers of chronically ill children use coping patterns related to maintaining social support, self esteem and psychological stability and understanding health situations more than the fathers in the study. 40 Family coping and the PICU From the previous studies, we can say that there is a relatively small body of empirical research focused on the coping of parents of children with congenital heart disease in general. At the same time, family coping in the PICU after heart surgery has received very little research attention. These families not only need to cope with lifethreatening surgery involving a vital organ, the heart, but also with the stress that any parent of a PICU-admitted child faces. However, relatively little empirical research documenting parental coping in this situation has been conducted Only one study has been identified in the literature that explored the coping of parents whose children were undergoing heart surgery. Lewandowski (1980) examined the stresses and coping styles of parents with children who had undergone open heart surgery. The researcher used two methods for data collection, observation and interview. First, she observed 59 parents of children undergoing open heart surgery while they were visiting their children for the first time in the intensive care unit. Then she interviewed the parents the day after the child’s surgery, when the child was still in the intensive care unit or in the general unit. She concluded that parents cope in a variety of ways during this stressful event. She observed emotional withdrawal from the situation, interest in the physiological aspects of the child’s condition (intellectualization), and restructuring, or focusing only on certain parts of the child and the illness as methods that parents used to deal with their child’s hospitalization in the PICU after open heart surgery. While this study gives us an understanding of how parents of children who have had heart surgery cope, it has some faults. The theoretical perspective for the study was not explained. The questionnaire format for interviews was not presented in the publication. 41 During the period of the child’s hospitalization in the PICU, researchers have described different coping strategies used by families to cope with their child’s hospitalization. For example, in (1985) Miles and Carter examined which parental coping patterns and staff behaviors are rated as helpful by parents of children admitted to the PICU with different diagnoses. The researchers developed a tool to measure the coping strategies used by parents in the PICU. This tool was developed from a review of the literature, other coping scales, and a pilot study done by the researcher. Parents were asked to identify coping strategies (appraisal-focused coping strategies, problem-focused coping strategies and emotion-focused strategies) that were used and which were helpful in relation to the PICU experience. Miles and Carter (1985) found that parents of PICU children used the following strategies (a) believing the child is getting the best care possible; (b) receiving as much information about the situation as possible; (c) praying: (d) being near the child as much as possible; (e) asking questions of the staff and (f) making sure the child is getting proper care. The generalizability of the findings of this study is limited by the small sample size; additionally, the psychometric analysis of the newly developed scale used to measure coping and the pilot study results that the researchers built their scale on were never reported in the literature Families viewed participation in their child’s care as a helpful way of coping with the admission of their critically ill child to the PICU. Noyes (1999) qualitatively assessed the experience of 10 mothers following an emergent admission of their infants to a PICU. Data analysis revealed that mothers were afraid, angry, shocked, and physically exhausted during the first hours of admitting their children to the PICU. Mothers highlighted how important talking, listening, and doing things for their child were, and 42 support from the nurses was described as a major factor in their ability to cope. LaMontagne and Pawlak (1990) used a mixed methodological approach to assess what parents perceive as stressful about their child’s PICU experience and what coping strategies they utilized to manage the stress. The researchers used the Ways of Coping instrument developed by Folkman and Lazarus to examine coping strategies in these situations. The subjects were 30 parents (24 women and 6 men) of children admitted to the PICU for medical reasons, trauma, and elective surgery. The study indicated that all of the parents used more emotion-focused forms of coping than problem-focused strategies. This study focused only on mothers, ignoring the fathers’ experience. Melnyk, Alpert-Gillis, Hensel, Cable-Beiling, and Rubenstein (1997) conducted a pilot study to examine the effectiveness of an intervention program called Creating Opportunities for Parent Empowerment (COPE) on critically ill children and their mothers’ psychological and coping outcomes. Eight instruments were used to collect data from 30 parents who were divided to two groups (14 control, 16 experimental). Mothers in the experimental group provided more emotional support to their children and reported less negative mood status after transfer from the PICU than mothers in the control group. Using a phenomenological research design, Carnevale (1990) interviewed 5 families of children admitted to the PICU. Families were interviewed during the first week following the transfer of their child out of the PICU. During the interview, families were asked to identify the main source of stress in the PICU environment and how they dealt with it. Families identified the use of five coping strategies to manage stress. In addition to social support, as identified by LaMontagne & Pawlak (1990), the study 43 showed these strategies to be cognitive behavior, interpersonal mechanisms, direct action, and support from the environment. Summary The previous studies indicated that most parents with chronically ill children, including those with congenital heart disease, attempt to use coping strategies/patterns to manage multiple demands in order to maintain or optimize the well-being and adjustment of their families. Some parents may have difficulty in using coping strategies/patterns to deal with situational stresses. These parents may be at risk of maladjustment. In addition to small sample sizes, there is a small body of research regarding coping among families of children who have undergone cardiac surgery. The literature also indicates that there is a need for nurses to facilitate the coping strategies most commonly used by parents of children with chronic illness, including congenital heart disease. Conceptualization of social support Social support is a multi-dimensional concept (Cutrona & Russell, 1990; House, 1981; House & Kahn, 1985; Dewcomb, 1990; Helgeson, 2002; Vaux, 1987) that has not been measured and defined in a homogenous way (Dewcomb, 1990; Jackson & Antonucci, 1992). Kahn (1979) viewed social support as interpersonal transactions that include one or more of the following: the expression of positive affect (feeling liked or loved) of one person toward another; the affirmation (feeling appreciated or admired) or supporting and respecting another person’s perceptions, behaviors, or expressed views and the giving of material such as money or symbolic aid to another. Aneshensel et al. (1995) defined social support as the degree in which a person’s basic social needs are met through informal or formal social networks while enhancing health and well-being, 44 regardless of their stress levels. In the social support literature, the terms social support and social network are often used interchangeably (Ell, 1996). The social network refers to a web-like structure comprising one’s relationships (Hall & Wellman, 1985). This network includes family, neighbors, friends, employers, relatives, fellow employees, professional networks, and groups with which a family shares common goals, interests, lifestyles or social identity (Friedman, Bowden & Jones, 2003). There are different types of social support. In spite of the conflict among researchers on the types of support and which type is more important to consider, most of the researchers agree that there are three types of support, emotional, instrumental, and informational (Cohen & Willis, 1984; Ryan & Austin, 1989; Tilden, 1985). Emotional support refers to personal behaviors such as having someone available to listen, to provide empathy, reassurance, caring, love and trust. Instrumental or tangible support is the result of concrete behaviors that help a person directly: the helping person intervenes personally in the problem situation and takes practical action such as help in household chores, giving a financial assistance, helping with work responsibilities, or giving some other form of material aid. Informational support helps individuals help themselves by providing them with information, guidance or advice that they can use to cope and manage a stressful situation (Helgeson, 2002; Cohen & Willis, 1984). The availability of social support can play a vital role in the adjustment of families of children with a chronic illness such as children with CHD (Carey, Nicholson & Fox, 2002). The availability of social support may help to stabilize families of children with chronic illness through reducing the impact of the illness’ stressors, by influencing the family’s appraisal of the stressor; or by assisting with revision of the family’s world 45 view (Dunst, Trivette, & Cross, 1986; Greenberg, 1983, McCubbin, 1996). Yet the social support available for families of children with chronic illness such as CHD tends to be inadequate. Social Support and CHD Friedman, et al., (2003, p.483) defined family social support as the social support that is perceived by family members to be available/accessible to the family (the social support may or may not be used, but family members perceive that supportive persons are ready to provide aid and assistance if needed). Family social support can either be internal family social support, such as spousal support or sibling support; or external family social support – the social supports external to the nuclear family (within the family’s social network). Carey, Nicholson, & Fox (2002) mentioned that social support is an important factor in facilitating adaptation and adjustment to parenting a child with CHD. However, the influence of social support on parental stress in families of children with CHD after heart surgery has been rarely studied. In one of the few studies investigating this issue, social support was inversely related to parent stress and child behavior (Uzark et al., 1992). That is, families with more stress reported fewer resources. Also, decreased family resources were associated with a higher number of behavior problems in their CHD children. This significant relation between family resources and children’s behavior problems suggested that social support is a factor that should be assessed in families of children with CHD. 46 Visconti (2000) investigated the relationship between parental stress and social support in a sample of 143 parents of children with CHD. This was a longitudinal study at 1 and 4 years after repairing the cardiac defect (Transposition of Great Arteries). The investigator used the Parenting Stress Index (Abidin, 1986) to measure parental stress, and the Social Support Network Inventory (SSNI) (Flaherty, Gaviria, & Pathak, 1983) was used to measure parental support (network support). The results supported the authors’ hypothesized relationship that parents who reported less social support would experience greater levels of stress. There were significant negative correlations between parental perceptions of stress and social support. Families with less social support reported more stress at both 1 and 4 years. The results of this study were congruent with the previous study by Uzark et al. (1992). Tak and McCubbin (2002) examined the relationship between social support, stress and coping in 92 families of CHD children. The samples were selected based on being a parent of a child 12 years old or under who was newly diagnosed with CHD within the last 3 to 4 months. The instrument used to measure social support was the Personal Resources Questionnaire (PRQ-85; Weinert & Brandt, 1978). Coping was the outcome variable and was measured by Coping Health Inventory for Parents (CHIP) (McCubbin et al. 1979). The mothers’ mean age was 30 years; the fathers’ mean age was 32 years, and the children’s mean age was 1.2 years, and 79% of the children were under 1 year of age. The results showed that the five dimensions of social support (social integration, intimacy, nurturance, self-worth and assistance/guidance) were positively related to individual parental coping. The researcher concluded that if a parent perceived more social support, they might also report a higher level of coping. The results 47 supported the previous literature suggesting a relationship between social support and coping. Another study by Katz (2002) investigated social support satisfaction received by 80 fathers and 80 mothers of children with life threatening (LT) chronic illness and parents of children with non-life threatening (NLT) chronic illnesses. The life-threatening illness group consisted of parents of children with cancers, heart disease, and a child suffering from an advanced kidney disorder who was receiving dialysis. The non lifethreatening groups were parents of 40 children with nephrological disease, asthma, juvenile rheumatic arthritis, and diabetes. The criteria that the researcher used to distinguish between children with LT chronic illness and NLT chronic illness were based on the attending physician’s opinion. If the physician anticipated the possible death of the child within a year after the interview, the chronic illness was considered life threatening. Katz used the Social Support Questionnaire (London, 1988). The results of the parents together and the fathers and mothers separately, and the parents of LT and parents of NLT chronic illnesses were compared using ANOVA. Parents of children with LT and NLT illnesses reported significant differences in social support. Fathers and mothers of children with LT illnesses received greater social support in all factors of social support (emotional support, practical support, and support received from the medical staff). Social Support and PICU Investigating social support among families of children who have undergone cardiac surgery has been ignored in the literature. However, there are some studies that have investigated social support of parents in the PICU relative to other diseases. Tomlinson, Kirschbaum, Harbaugh, and Anderson, (1996) explored the relationships 48 among illness severity, family resources, and maternal uncertainty during the initial stage of a child's hospitalization in a pediatric intensive care unit for a life-threatening illness. A convenience sample of 40 mothers rated perceptions of uncertainty using Norbeck's Social Support Questionnaire. Results indicated a positive association between illness severity and maternal uncertainty and a negative association between family cohesion and maternal uncertainty. Research has, however, also addressed the possible negative outcomes of social support (Tomlinson, & Mitchell, 1992; Rook, 1982; Schuster, Kessler, & Aseltine, 1990; Finch, Okun, Pool, & Ruehlman, 1999). Negative support refers to the recognition that support may be also a source of stress (Stewart, 1989; Rook, 1982; Finch, Okun, Sc Pool, & Ruehlman, 1999). Tomlinson and Mitchell (1992) addressed the possible negative outcome of social support in their study. They used a qualitative approach to investigate the nature of family social support during an unexpected admission of a child to the PICU. Examples of the child’s illness included accidental trauma, acute meningitis, and acute nephrotic syndrome. A non-random convenience sample of 10 families was obtained from two pediatric intensive care units. Tape-recorded interviews of parents took place in the hospital 2 to 13 days after admission to the PICU. Results indicated that social support can have a negative effect on the families of critical care children. Six of the 10 families (60%) indicated their frustration over unwanted support, and they felt that they sometimes had to return the support. The authors suggested that the nurses can provide a “gatekeeper” role for the family so the family can concentrate on other family tasks. 49 Conceptualization of Adjustment Family adjustment is a very complex phenomenon which is defined and assessed in a variety of ways (Welcher, 1997; Sholomskas et al., 1990; Tennen & Affleck, 1990; Thomson et al., 1992). Family adjustment in the Resiliency Model is a continuous process and can be described as good (bonadjustment), which requires only minor changes in family functioning; or it may be poor (maladjustment), which precipitates a crisis (which is a continuous state of disorganization, disharmony, or imbalance in the family unit) and requires major changes in family functioning (Friedman et al., 1998; McCubbin et al., 1996). Figley (1989) defined family adjustment as the ability of the family to respond to developmental or situational stressors with appropriate shifts in the power structure and relationship roles. Family adjustment is reflected in the characteristics of family functioning (Ketchum, 2000; Spence, 1992). Families who have the ability to solve their problems, have established patterns of behaviors and functions, are able to provide nurturance and support to their members, and have the ability to maintain open communications between family members are better able to adjust to stressful situations (Epstein, Baldwin, & Bishop, 1983). Communication has been emphasized as having a very important role in facilitating family functioning and adjustment (Olson, Sprinkle, and Russell, 1979,1982). Through the use of communication, the family is able to change its levels of adaptability allowing for healthy adjustment and growth Family functioning has been found to be associated with child adaptation in children with chronic illness (Drotar, 1997; Failla & Jones & King et al., 1999; Soliday et al., 2001). In a review of research concerning the relationship of parent and family 50 functioning to the psychological adjustment of children with chronic health conditions, Drotar (1997) concluded that less adaptive family relationships involving greater family conflict and greater maternal distress predicted problems in adaptation in the child. McCubbin, McCubbin, Nevin, and Cauble (1981) mentioned that it is important to assess several dimensions of family life to be able to understand family adjustment. These dimensions are family stressors, strain and conflicts which make the families vulnerable to the impact of a subsequent stressor or change; family hardiness, a stress resistance and adaptation resource in families which would function as a buffer or mediating factor in mitigating the effects of stress and adaptation over time such as social support that families can get from friends, relatives and the community; and family cohesion, which is the expression of unity, support, and emotional bonding between family members. Conclusion Theory development and research about families has increased our knowledge regarding family adjustment, but it has also contributed to the complex perspective of family adjustment. As a result of the various theoretical approaches, researchers use the term family adjustment in different ways. A universal definition of family adjustment has not been resolved. Family Adjustment and CHD Research on the effect of having a child with congenital heart disease on family adjustment is limited. In a study which examined maternal perceptions and medical severity on the adjustment of children with CHD, with 99 mother-infant dyads (DeMaso et al., 1991), investigators concluded that maternal perceptions had a greater impact on 51 the child’s long-term adjustment compared to the severity of illness. Increased maternal stress, as measured by the Parenting Stress Index (Abidin, 1986), was reported to have the strongest relationship to the mother’s report of the child’s adjustment. An important limitation of this study was that the children’s adjustment to their cardiac illness was based on maternal self-report questionnaires with variable reliability. In their study of parents of adolescents with CHD, Messias, Gilliss, Sparacino, Tong, and Foote (1995) examined parents’ reminiscences of the experiences associated with their infant’s initial diagnosis of CHD. Despite the passage of many years since the diagnosis, parents had vivid memories of this life-changing event. Messias et al. (1995) described several themes in the process of adaptation from the crisis of diagnosis to the incorporation of its meaning to the family. Either infant characteristics or the health care provider’s verbal and/or nonverbal expressions of concern led parents to the conclusion that “something was wrong” with their baby. The diagnosis came as a shock, described as a “rude awakening,” or occurred more insidiously, as data on the infant’s condition unfolded over time. When parents acknowledged the diagnosis, they were forced to come to grips with the “illusiveness of normality” as their expectations for a normal child were profoundly challenged. Through childhood, these parents identified “managing uncertainty” about their child’s condition and treatment decisions as a characteristic of their parenting. They faced their child’s mortality in a way not experienced by parents of healthy children. Finally, to incorporate the reality of having a child with CHD into their lives, parents created “new meaning” for themselves and their child, using philosophical or spiritual terms. This included “taking stock,” in which parents evaluated the positive and negative impact that the diagnosis of CHD had on their family. 52 Uzark et al. (1992) designed a study that was based on the Double ABCX model (McCubbin, Patterson, 1983) to investigate the psychosocial impact of pediatric cardiac transplantation on both children and parents. The results indicated that heart transplant families reported greater family stress than families with children with no chronic conditions. Also, the pile-up of family stressors and decreased family resources were important negative correlates of the pediatric heart transplant recipient’s psychological adjustment, as manifested by behavior problems and social competence. Difficulty in the adjustment of parents of CHD children has been reported by researchers outside the USA. For instance, a Swedish study (Lawoko & Soares, 2002) compared distress and hopelessness among parents of children with congenital heart disease, parents of children with other diseases, and parents of healthy children. The sample was comprised of 1,092 congenital heart disease parents, 112 parents of children with other diseases, and 293 parents of healthy children. The instrument used to measure distress was the SCL-90-R (Derogatis, 1994). The SCL-90-R is a 90-item 5-point Likert self-report questionnaire. Items are grouped into nine subscales. The subscales are somatisation, obsessive-compulsive, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation and psychoticism. In this study, Lawoko & Soares (2002) used only the depression, anxiety, and somatisation subscales. Hope was assessed by the Hopelessness Scale (Beck, Kouacs, & Weissman, 1975). The results showed that the level of distress was higher in parents of children with CHD than parents of children with other diseases and parents of healthy children. Parents of children with congenital heart disease reported greater anxiety and somatisation than parents of healthy children. In addition, parents of CHD children reported greater levels of hopelessness 53 than parents in the other parent groups. Mothers of CHD children were more distressed and felt greater degrees of hopelessness than fathers. The strengths of this study were its use of a large sample size and its use of a comparison group. The limitations were that no theoretical framework was described in the study, and the instruments were not thoroughly described. The same results were obtained by Pelchat et al. (1999), a Canadian researcher and his team found that parents of CHD children in Canada have higher psychological distress than parents of children with a cleft lip and/or palate or parents of non-disabled infants. Researchers have addressed the effect of a child’s disease on adjustment in families with other chronic illnesses. For example, Ferrell, Rhine, Shapiro, and Dierkes (1994) found that some families of children with cancer believed the child’s experience brought the family closer together, while other families thought the illness caused relationships to be tense and distant. Sawyer, Antoniou, Toogood, & Rice (1997) examined the adjustment of young children and their families during the first 2 years after the child’s diagnosis with cancer. Parental adjustment was assessed by means of the 28item General Health Questionnaire (GHQ), which was designed to measure nonpsychotic psychological impairment in the areas of somatic symptoms, anxiety and insomnia, social dysfunction, and depression in adults living in the community. Familial adjustment was assessed using the General Functioning Subscale of the Family Assessment Device (FAD), and was completed by the mothers in each family. Also Cadman, Rosenbaum, Boyle, and Offord (1991) surveyed both mothers and fathers in over 1,800 families sampled to be representative of the population of Ontario, 54 Canada. Mothers of children with chronic illness reported more negative affect than did those with well children. Mental health treatment was reported 2-3 times more frequently by these mothers and fathers as compared to parents of well children. However, there were no differences in single parent families with chronically ill or well children. Healthy family functioning is an important indicator of family adjustment (Ketchum, 2000; Spence, 1992). The relationship between mother and father is important, and a child with chronic illness may cause a strain on this relationship (Hentinen, 1997). Rivara et al. (1992) found that the severity of the child’s injury was related to the degree of stress, quality of relationships, coping, and the interviewer’s rating of global family functioning at 12 months post-injury. Families with severely injured children had greater deterioration from 3 to 12 months in terms of psychological strain and well-being and child/sibling and child/peer relationships. Although there were slight decreases in interviewer ratings of global family functioning with families of severely injured children, changes in scores on the Family Environment Scale (FES), the Family Inventory of Life Events (FILE), and the Coping Health Inventory for Parents (CHIP) from 3 to 12 months were not significant. This discrepancy could be due to the differences between insider and outsider perspectives on the family. Family Adjustment and the PICU Investigating the adjustment of families of children who have undergone cardiac surgery has been ignored in the literature. However, there are some studies that investigate the adjustment of parents in the PICU related to different kinds of diseases. Philichi (1989) assessed family cohesion and adaptability in 50 parents of PICU children, 55 after the children’s third day in the PICU. The researcher used two measures to collect data, the Family Adaptability and Cohesion Evaluation Scale (FACES-III) and the Family Crisis-Oriented Personal Scale (F-COPES). The results of this study indicated that the majority of families (70%) fell into the balanced categories of adaptability and cohesion. Comparisons of the parents’ cohesion and adaptability scores with published norms revealed significantly higher cohesion scores for the PICU parents. Differences between mothers’ and fathers’ cohesion scores were not significant. However, the mothers’ adaptability scores were significantly higher than the fathers’ (mothers believed their families were more adaptable than did fathers). It is not clear from the report whether the mother-father comparisons were done within families, which would have strengthened the results, or across families. Berenbaum and Hatcher (1992) have compared 20 mothers of children in the PICU with 20 mothers of children on the general pediatric medical surgical unit, and 20 mothers of non-hospitalized children with minor acute illness. The PICU group includes mothers of children admitted to the PICU with infectious disease, neurological problems, and respiratory, cardiac and hematologic problems. Data were collected within 24 hours of the child‘s admission. Mothers of PICU children were significantly more confused, anxious, angry, and depressed than the mothers of children in the general pediatric and surgical units and mothers of non hospitalized children. Mothers in each of the groups experienced their children’s illness differently, but it is not known whether these group differences during hospitalization produce different long-term effects. All the subjects were Caucasian, and this might lead to a lack of generalizability of the findings. 56 Several measures were used by family researchers to measure adjustment of family members when they have a critically ill child. The General Health Questionnaire (GHQ) examined family psychological adjustment following patient admission to the hospital for trauma and found that there was no relationship between coping, perceived severity of injury, or previous life stressors and levels of psychological adjustment (Hill, 1993). Lesk and Jiricka (1998) used the Family Member Well-Being Index (FWBI) and the Family Assessment Device (FAD) to measure adaptation among families with a member who has suffered brain injury. Data collection occurred within two days following the injury, which provided little time for family members to adjust, let alone adapt to the crisis situation. The results indicated that “pile-up” of life stressors accounted for 40% of the variance in family adaptation, as measured by the Family Member WellBeing Index (FWBI), and 16% of the variance in family adaptation as measured by the Family Assessment Device (FAD). These results indicated that the accumulation of life stressors had a significant negative impact on family adaptation. The FWBI was also used by another researcher to measure adjustment (Reider, 1989). Youngblut and Shiao (1993) measured family functioning at 24 hours after PICU admission and at 2-4 weeks after hospital discharge with a sample of 9 two-parent families. The mothers’ cohesion scores decreased significantly from Time 1 to Time 2. Both mothers and fathers scored their families as significantly more adaptable than published norms, though their cohesion scores did not significantly differ. Greater length of hospital stay was related to greater satisfaction with family for fathers. However, the longer the child was intubated, the lower the mother’s perception of family cohesion and the greater her dissatisfaction with family. 57 In a cross-sectional, comparative study, Youngblut and Lauzon (1995) compared 27 families whose child under 5 years old had been hospitalized in the PICU and general care unit (GCU). Data were collected within 3 years of their child’s discharge. These researchers found that the two groups did not differ on their ratings of their family’s cohesion, adaptability, and satisfaction with relationships, even when the time since discharge was controlled. However, longer hospital stays and greater severity of illness were related to lower family cohesion ratings by fathers, and greater severity of illness scores and being in the PICU group were related to lower adaptability by mothers. Summary There were relatively few studies measuring adjustment among families of CHD children who have undergone heart surgery. Also, research on family adaptation in families of chronic/critically ill children reflects various interpretations and dimensions of the term family adjustment, such as family functioning, positive psychological development, and family adaptability. In addition, the instruments used to measure adjustment of family members varied greatly. Measurements tended to focus on only one or a limited number of dimensions of the multifaceted phenomenon of family adjustment. There is a need to address family adjustment in children who have undergone heart surgery and to investigate factors that enhance positive family adjustment. It appears that the conceptualization of adjustment differs for researchers and that many different ways of measuring adjustment have been attemp McCubbin & McCubbin (1991) recommended McMaster’s Family Assessment Device (Epstein et al., 1983) for measuring social adjustment of families of chronic child illness. 58 Linkage Between Study Variables Social Support, Stress and Adjustment Social support is often viewed as one of the primary resources that enhances family adjustment, reduces pileup of demands, and buffers against stress (Fink, 1995; Grossman, 1995; McColl, 1995; Snowdon, Cameron, & Dunham, 1994; Tomlinson, Kirschbaum, Harbaugh & Anderson, 1996). Social support is crucial for parents to successfully cope and adapt to a child’s chronic illness (Mastroyannopoulou, Stallard Lewis & Lenton, 1997; Tomlinson, Kirschbaum, Harbaugh & Anderson, 1996). Parents experiencing stress as a result of a child’s chronic illness have described the need for all kinds of support – informational, emotional, and instrumental – to be able to face the stress of caring for a chronically ill child (Cohen, 1999; Mercer & Ritchie, 1997; Patterson & Garwick, 1994). Moderating effects of social support Social support has two sorts of effects: mediating and moderating effects (buffering effect) (Cohen & Wills, 1985; House, Landis, & Umberson, 1988). The mediating model proposes that social support functions as an intervening variable between the stressor and outcome (Quittner, Glueckauf, & Jackson, 1990). The moderating effect proposes that support can buffer the effect of stress (Antonovsky, 1974; Caplan, 1974; Cassel, 1976 & Cobb, 1976). Some evidence has been obtained for the moderating effect of social support on parental psychological adaptation to the stressors of caring for a child with a chronic disease. For example, Speechley and Noh (1992) examined whether the continuing emotional strain of parenting a child who has survived cancer is associated with elevated 59 levels of psychological distress in parents. The design of this study was cross-sectional. Data obtained from 63 families (63 mothers and 49 fathers) were compared to a matched sample of parents (64 mothers and 62 fathers) with healthy children. The two samples of families were equivalent in terms of family composition and socioeconomic status. Perceived social support was measured using the Provisions of Social Relations Scale, which was designed to test respondents’ perceptions of their social relationship in relation to five of the provisions, including attachment, social integration, reassurance of worth, reliable alliance, and guidance, on a 5-point scale ranging from “very much like my experience” to “not at all like my experience.” Depression and anxiety were measured using the CES-D and STAI, respectively. The results indicated that perceived social support had a significant inverse relationship with psychological distress for both parents. When parents of cancer survivors were compared to those of healthy children, there were no differences in levels of depression or anxiety overall. In addition, stress associated with the uncertainties surrounding survival from childhood cancer was not related to the parents’ depression and anxiety. In addition, the potential buffering effects of social support on parental psychological adaptation to the stressors of caring for a child with another chronic disease (sickle cell disease) have been studied by Ievers, Brown, Ambert, Hsu, & Eckman (1998). They examined the moderating effects of family functioning and social support on the relationship of child-related stressors to caregivers' psychological adaptation in a sample of caregivers of children with sickle cell disease. It was hypothesized that caregivers’ perceptions of their family functioning (more cohesive and flexible family functioning) and social support (satisfaction with support networks and 60 greater access to resource support) would buffer the effect of potentially stressful child behavior problems and disease severity on caregivers’ psychological adjustment. Participants were 67 caregivers of African-American children and adolescents with sickle cell disease. These researchers found a moderating effect of family functioning on the association of children's externalizing behavioral problems to caregivers' symptoms of hostility. Greater levels of cohesive and adaptive family functioning buffered the potentially detrimental effects of caring for children perceived as hard to manage. No evidence was obtained for the moderating effect of parents’ satisfaction with their social networks or their level of resource supports. The participants of this study were African American caregivers only; thus, the generalizability of the findings could not be made across various ethnic and culturally diverse groups. Peterson (1984) tried to investigate if external support mechanisms function as resources which moderate mothers’ stress related dysfunction associated with their handicapped child. The prediction of moderating variables was derived from Hill’s (1949) ABCX Family Crisis Model. Resources, the moderating variable, included physical and emotional support, sufficient finances to meet medical costs, the presence of love and affection in the home, and satisfaction with community services for the handicapped. Petersen’s work offers important information regarding different resources that may influence the way mothers experience the stress related to caring for a handicapped child and the role of support in moderating the experience of stress. One of the limitations of this study was that the researcher did not analyze the possible subscales within the resources variable. It is possible that one or more of the resources recognized 61 in the instrument were more helpful than others, though this was not analyzed in this study Mediating effects of social support Mediation models have rarely been addressed in the previous studies of families of children with congenital heart disease. Only one study has been identified that investigated the effect of social support as a mediator between stress and coping among parents who have children 12 years and under who are newly diagnosed (in the last 3 to 4 months) with CHD (Tak & McCubbin, 2002). The researchers found no mediating effect of social support, only a main effect between social support and coping, which shows that social support is positively related to parental coping. Stress and Adjustment The Resiliency Model of Family Stress, Coping and Adaptation (McCubbin, Thompson, & McCubbin, 1996) proposes that in crises, increases in prior stressors, strains, and transitions are negatively related to family adaptation and adjustment outcomes. Kaul (1995) indicated that the overall number of negative stressors that mothers of children with CHD experienced during the past year are negatively correlated with the mothers’ psychological adjustment. The same results have been reported by two different researchers (Leske & Jiricka,1998; and Welcher, 1997). Leske and Jiricka (1998) used the Resiliency Model of Stress, Coping and Adaptation as a theoretical model and found that in families of brain injured patients in the PICU, prior stressors, rather than the actual stressor event (brain injury), adversely influence psychosocial family adaptation. Prior stress, as measured by the Family Inventory of Life Events (FILE), accounted for 16% of the variance in family adaptation as measured by the 62 Family Adaptation Scale. The addition of family coping and family resources explained 44% of the variance in family adaptation. In a descriptive, correlational study, Welcher (1997) assessed the extent to which the selected variables (family demands, family type, family resources, family appraisal and family coping) explained and predicted family adjustment in a sample of 75 parent dyads with a deaf child. Welcher (1997) used McCubbin and McCubbin’s (1993) Resiliency Model of Stress, Adjustment, and Adaptation as a theoretical framework to guide the study. Family adjustment was measured by two instruments, The Symptom Checklist-90-Revised (SCL-90-R) ( Derogatis & Cleary, 1977) and the Family Assessment Device (FAD) (Epstein et al., 1983). The results indicated that an increased pile-up of prior stressors, strains, and transitions was related negatively to family adaptation. Coping and Adjustment Little research exists in congenital heart disease populations to explain the relationship between coping and adjustment. Davis, Brown, Bakeman, & Campbell (1998) found that emotion-focused coping characterized by self-blaming and avoiding emotions was negatively associated with maternal adjustment. In addition, there is incongruence in the research results that have investigated the relationship between coping and adjustment in other populations with chronically ill children. For example, Barbarin and Chesler (1984) found that coping strategies are not related to adjustment for parents. Welcher (1997) found that parental coping as measured by CHIP was not significantly related to parental adjustment as measured by FAD with deaf children. In 63 contrast, Thompson et al. (1994) found that the use of palliative methods of coping has been associated with poor adjustment in mothers of children with chronic illness. Stress, Coping, and Adjustment The relationship between stress, coping, and adjustment has not been studied in parents of children with CHD after the child’s admission to the PICU following heart surgery. One study by Davis et al. (1998) studied which of the following factors predict adjustment for 52 mothers of children with CHD. These factors were the mother’s and child’s demographic factors, the mother’s daily hassles, methods of coping, and family function. The sample included mothers of children in different stages of illness such as children who were admitted to the hospital for post-surgical monitoring, those admitted for treating complications after previous cardiac repairs, and preoperative children. These researchers used the Brief Symptom Inventory (Derogatis, 1975) to measure mothers’ psychological adjustment, the Ways of Coping Questionnaire (Folkman & Lazarus, 1980) to measure coping, and stress was conceptualized as arising from both daily and illness related stress. Daily stress was assessed using the Hassles and Uplifts scale developed by DeLongis, Folkman, and Lazarus (1988). The results indicated that approximately 37% of the mothers met the criteria for poor adjustment as measured by the Brief Symptom Inventory. Stress arising from daily hassles and increased use of palliative coping techniques (using-emotion focused coping such as self-blaming and avoiding emotions) were negatively related to maternal adjustment. Specifically, the mothers’ coping styles accounted for 15% of the variance in maternal adaptation. Family support accounted for only 1% of the variance in maternal adjustment. There were some limitations in this study such as its small sample size (52) mothers, and most of the mothers were 64 predominantly African-American, and these limitations might affect the generalizability of the findings. Moreover, the researchers used a stepwise regression as a method of data analysis, and it was not fully explained by the researchers. Coping and Stress Ray and Ritchie (1993) examined 29 parents’ perceptions of the stressfulness of coping with their chronically ill child’s home care. The parents were the primary caregivers for children 2 months to 16 years of age who had been diagnosed from 3 months to 7.5 years ago, and who had been receiving illness care at home for 1 to 7 months. Parental stress and coping were assessed using an unsegmented 100 mm visual analogue scale (VAS) and the Coping Health Inventory for Parents (CHIP), respectively. Zero millimeters on the VAS represented not stressful at all and 100 mm represented the most stressful. When regression analysis was performed, coping, as measured by the total score on the CHIP, was not associated with parental stress. Effects of Parents’ Demographic Variables on their Adjustment Gender Few studies have explored whether differences in adjustment exist between mothers and fathers of children with CHD in the PICU. The mothers of 68 children undergoing cardiac surgery demonstrated greater psychological distress and manifested greater problems than did the fathers (Utens, Versluis-Den Bieman, Verhulst, Witsenburg, Bogers, and Hess, 2000). Mothers of children hospitalized in the PICU believed their families were more adaptable than did fathers (Philichi, 1989) Age Demographic-related factors can have varied effects on family members as they encounter potentially stressful situations. Younger mothers of hospitalized children in the 65 PICU exhibited greater emotional distress than older ones (Berenbaum and Hatcher, YEAR?). (Svavarsdottir & McCubbin, 1996) reported that older mothers reported less helpful coping related to strengthening family life and maintaining optimism than did younger mothers. Also, older fathers reported less helpful coping behaviors related to coping pattern two (managing psychological tension) maintaining social support, selfesteem and psychological stability. Tak and McCubbin (2002) found that younger mothers reported more helpful coping related to family integration, cooperation and optimism, and the pattern of medical communication and consultation. Younger fathers reported more helpful coping related to maintaining social support, self-esteem and psychological stability. Effects of Child’s Age on their Parents Adjustment Svavarsdottir & McCubbin, (1996) found that the age of the child with congenital heart disease is negatively correlated with fathers’ coping. Fathers who had younger infants diagnosed with CHD reported more helpful coping strategies in all three areas of coping as measured by the Coping Health Inventory (family, self, and the health care situation). On the other hand, more distressed mothers tended to have younger children with congenital heart disease (Kaul, 1995). Other studies have explored the association between the age of the child and the parents’ adjustment in other chronic illnesses. For example Diviney (2001) found that the child’s age was significantly related to the mother’s coping (r=.34, R2=.12) in their sample of developmentally disabled children; the author found that the child’s age and not his/her limitations per se accounted for variations in maternal coping. 66 Conclusion While many of the studies cited in this review have looked at the family as a whole, it is usually the mother who bears the greatest responsibility for the child with CHD. Studies have found that mothers spent more time providing care, offered more types of support, and perceived more caregiving burden than did fathers. Many of the studies to date are limited by their lack of operational definitions of stress, coping, social support and adjustment. More comprehensive assessment of the potential influence that stress, coping, social support has on family adjustment warrants further investigation. 67 CHAPTER III Methods Introduction The purpose of this study is to explore the relationship between family and child demographic characteristics, stress, social support, coping, and adjustment in families who have a child in the PICU after heart surgery. This chapter will describe the methodology for this study, including the study design, sampling methods, instrumentation, data collection procedures, data management, data analysis, and protection of human rights. The Study Design The study design is a descriptive correlational cross-sectional design that involves the collection of data from the population of interest. This study is a non-experimental study since the independent variables of stress, coping, and social support will not be manipulated. The ages of the parents and children and the parents’ genders, will all be statistically controlled since they are extraneous factors known to influence the study variables. This design was selected for this study following the recommendations of Polit & Hungler (1999). Cross-sectional correlational studies allow flexibility in investigating and describing the relationships among phenomena at a fixed point in time. Such studies also provide a baseline for future and more rigorous research studies (Brink & Wood, 1989). It would have been preferable to use a longitudinal design to explore changes in family stress, coping, and adjustment over time as the treatment process progressed. However, practical considerations related to the cost of longitudinal research and the investigator’s time constraints prevent the use of this methodology at this time. This 68 study will use the Resiliency Model of Family Adjustments and Adaptation (McCubbin & McCubbin, 1993) to answer the research questions concerning the proposed relationships among the study variables. Setting and Sample Setting Participants for the study were recruited from the pediatric intensive care unit at university hospitals of Cleveland and from the pediatric intensive care unit in at the Cleveland clinic foundation in Cleveland, Ohio. Inclusion and Exclusion Criteria The subjects in this study were parents of children (0-12 years old) who have had heart surgery. The parents must be at least 18 years old. The parents must be able to understand, speak, read and write English. Additionally, the parents must have completed the ninth grade and be able to understand the purpose, benefits, and risks of the study. They must be able to sign a consent form and to understand and answer the questions in the research instruments. The child can have other physical or developmental disabilities. Parents of all socioeconomic levels included in the study. The child’s condition must be stable at the time of data collection. Only one parent per child was included. A convenience sample of 74 parents (biological, adopted, foster) was obtained from the Pediatric Intensive Care Unit at University Hospitals of Cleveland. The advantages of choosing convenience sampling are that it is inexpensive, accessible, and requires less time than other types of samples (Burns & Grove, 1997). On the other hand, the disadvantage of convenience sampling is that it provides little opportunity to control for biases because subjects are included in the study because they happened to be in the 69 right place at the right time (Burns & Grove, 1997). This may result in recruiting subjects who are not representative of the population of interest and may decrease the generalizability of the findings. However, convenience sampling is a useful sampling method and is commonly used in behavior studies (Burns & Grove, 1997). Recruitment of Subjects A convenience sample of 74 parents who meet the study’s criteria were recruited from the Pediatric Intensive Care Unit at University Hospitals of Cleveland and at the Cleveland Clinic Foundation in Cleveland, Ohio. Parents who meet the study criteria approached by the investigator 24 hours after their child’s operation, and invited to participate in the study. Data collection for this study lasted for 17 months. Two hundred eligible families were approached to participate in the study. Of the 200 eligible families only 74 families (8 fathers, 66 mothers) agreed to participate in the study. Reasons for refusal were: did not want to be bothered, too tires, too sleepy, asking the investigator to come back later to pick up the questionnaire and parents never returned the questionnaire. Two participants completed and returned the questionnaires but did not sign the consent form. One participant returned the questionnaire but completed only the first scale (FILE).These three participants’ data were not included in the analysis. The final sample size was 74 participants. The response rate was 37%. Sample Size The sample size for the study was based on Cohen’s (1988) technique for power analysis. Power analysis is a method for reducing Type ΙΙ errors; the possibility of incorrectly accepting a false null hypothesis (Pedhazur & Schooler, 1991). In power analysis, there are four components: effect size (gamma), significance level (alpha), 70 power (1-β) and sample size (Burns & Grove, 1997; Cohen, 1988; Pedhazur & Schooler, 1991; Polit & Hungler, 1999). When three of the four parameters are known or estimated by the researcher (effect size), the fourth can be calculated using power analysis, which for this study is the sample size. Effect size is defined as the degree to which the null hypothesis is false (Cohen, 1988), and the strength of the effects of the independent variables on the dependent variables (Polit & Hungler, 1999). The estimated magnitude of the relationship between independent and dependent variables is important in determining sample size to reduce the risk of a type ΙΙ error (Polit, 1996). As effect size increases, so does the power. Effect size can be established by examining the effect size in previous studies or by using a conservative value (small, moderate or large) (Pedhazur, 1992; Polit, 1996). To answer the proposed research questions, this study requires the use of correlation and regression analysis. Previous researchers studied the effect of stress and coping on adaptation of CHD children (Davis & Brown, 1999), and Kaul (1995) studied the effects of social support, quality of relationship and stress on psychological adaptation of mothers of children with congenital heart disease. They found R2=.37 and R2=. 38, respectively, using multiple regression analysis. The formula provided in Cohen (1998) for estimating the effect size is as follows: f= R2/1-R2 Therefore, the effect size for these previous studies will be .58 and .59, which are considered large effect sizes. Because effect size depends on the types of variables in the study (Cohen, 1988) and the previous studies used some, but not all of the variables used in the current study, a medium effect size of .15 will be used to estimate the sample size. 71 The level of significance is the alpha level. This is associated with Type 1 error, which is the probability of rejecting the null hypothesis when it is true (Stevens, 2002). An alpha of .05 was chosen based on an analysis of the risks and benefits of Type I versus Type II error. For this study, the alpha will be set at .05. According to Cohen (1988), an alpha level of .05 provides the minimum basis for rejecting the null hypothesis in most areas of behavioral science. The minimum acceptable power for a behavioral study is .80 (Burns & Grove, 1997). In this study, the power is .80, indicating that there will be an 80% chance of rejecting the null hypothesis and a 20% risk of a Type ΙΙ error. A Type ΙΙ error occurs when the null hypothesis is not rejected even though differences actually exist. Using Cohen’s technique for power analysis, a sample size for correlation and multiple regression analysis was computed for an alpha of 0.05, a power of 0.80, a medium effect size of 0.15, and 7 independent variables on the basis of the following formula: N= [L/γ] +K+C+1 (Cohen), (whereas lambda (L) from Cohen’s (1988) chart = 15.6, effect size (f2) = .15, independent variables = 7, and control variables C= 3, a sample size of 114 was estimated. N= [15.6/. 15] +6+3+1=114 As indicated above, the necessary sample size for the current study was estimated to be 114 subjects based on an alpha of 0.05, a power of 0.80, and a medium effect size of .15. The data collection took about 17 months in order to recruit the obtained sample size of 74. However, in spite of the researcher’s attempts to get the required sample size from two different settings, only 74 subjects completed the study. 72 Procedure for Data Collection Prior to initiating the project, the study was approved by the Institutional Review Board (IRB) committees at University Hospitals of Cleveland and the Cleveland Clinic Foundation. Within 24 to 48 hours after the child’s admission to the PICU after heart surgery, the investigator approached the parent(s) who met the sampling inclusion criteria and invited them to take part in the study. The investigator informed the parents who agreed to be in the study of the study’s purpose, data collection procedures, and about the protection of their confidentiality and their freedom to drop out at anytime. All information was provided in both verbal and written form. Then the consent form was given to the parents. Data collection for this study was self-administered. All the questions for the study were formatted for self-administration. The questionnaire required about 20-30 minutes to complete. Even if both parents were available, only one parent per child was asked to complete the questionnaire, and it was left up to the parents to decide who would complete the questionnaire. Participants were asked to complete the questionnaires in a paper and pencil format. The advantage of this method is that the questionnaire offers the possibility of complete anonymity, and there is no interview bias (Polit & Hungler, 1999). The disadvantages of this method are as follows: (a) it is more likely that the number of unanswered questions will be higher than in an interview and (b) the researcher will not be available to provide clarification regarding the directions or the questions, nor can the researcher provide encouragement for the participant to complete all of the questionnaires in the packet. 73 The researcher put the questionnaire and the information letter in an envelope and gave it to the participant. The parents were given an opportunity to ask questions before they were instructed to complete the questionnaires independently. The researcher asked the parents if they would prefer to complete the questionnaire at that time, in which case the researcher would wait for them and be available to provide answers to their questions, or if they would prefer to complete the questionnaire later. Parents were instructed to place their completed questionnaire in the envelope provided, seal the envelope, and then deposit it in the designated box at the PICU nurse’s station. The questionnaires were collected daily from this box or from the subjects on the day following administration. Instrumentation Stress Stress in this study was conceptualized as encompassing the stress arising from intra-family strain, stressul family life events (McCubbin et al, 1996) and dimensions of environmental stress in the PICU (Miles, Carter, Hennessey, Eberly, & Riddle, 1989). Stress was measured using two instruments: (1) the Family Inventory of Life Events (FILE) and (2) the Parental Stressor Scale: PICU. Family Inventory of Life Events (FILE) Family stress will be measured by using a modified short version of the Family Inventory of Life Events (FILE) (Musil et al., 2001) which consists of 34 yes/no items (See Appendix A). It is a self-report instrument that is designed to measure the pileup of stresses and strains experienced by a family during the past year. Two subscales are used in this study – the Stressful Family Life Events and Intra-family Strain subscales. The Stressful Family Life Events subscale is composed of 10 dichotomous items while the 74 Intra-family Strain subscale is composed of 9 dichotomous items. The Stressful Family Life Events subscale contains items that are stressful to families such as “a family member ran away from home” or “a child died.” The Intra-family Strain Subscale includes items such as “increased conflict between husband and wife,” “increased arguments between in–laws and relatives.” The score for the two subscales was computed by giving each yes response a score of 1. The yes responses were then summed to arrive at a summary score for the total subscales. The original FILE (McCubbin, et al., 1996) consists of 72 items arranged in 8 subscales and includes (a) Intra-family Strains, which reflects sources of tension and conflict between family members and difficulties in enacting the parental role; (b) Marital Strains, which measure stressors in the marital role arising from sexual or separation issues; (c) Pregnancy and Childbearing Strains, which relate to pregnancy difficulties or adding a new member to the family; (d) Finance and Business Strains, which assesses resources of increased strain on a family’s money supply and strain arising from familyowned businesses or from investments; (e) Work Family Transitions and Strains, which is related to a family member moving in or out of the work force, changes occurring at work, or moves made by the family or one of its members; (f) Illness and Family Care Strains, which reflect dependency needs arising from injury or illness of a family member or friend or problems with child care, strain related to the onset of or increased difficulty with chronic illness, and the strain of a member or relative requiring more help or care; (g) Losses, which reflects losses due to the death or a member’s moving out or moving back home, or beginning a major involvement outside the family; (h) Transitions In and Out, which reflects a member or members moving out, or beginning a major involvement 75 outside the family; and (i) Legal, which focuses on a member breaking society’s laws or mores. The internal consistency reliability of the FILE was initially reported as .72 as determined by Cronbach’s alpha; however, in later studies (n= 1330 and n=1410) the reported alphas were .79 and .82; the alpha for the combined sample (n= 2740) was .81 (McCubbin & Patterson, 1996). Parental Stressor Scale: PICU Parental stressors were measured using the Parental Stressor Scale: Pediatric Intensive Care Unit (PSS: PICU) (Carter & Miles, 1984). The PSS: PICU is a 37-item Likert-type scale designed to measure parental stress arising from seven dimensions of the ICU: Child’s Appearance (3 items), Child’s Behavior and Emotions (10 items), Parental Role Alteration (6 items), Sights and Sounds (3 items), Procedures (6 items), Staff Communication (5 items) and Staff Behaviors (4 items). Stressors are described as experiences that cause parents to feel anxious, upset, or tense. The dimension “Child’s Appearance” includes various aspects of the child’s physical appearance, such as bruises and/or incisions and cuts, which might be a source of stress for parents. The dimension “Child Behavior and Emotions” includes items which describe various behaviors and emotional responses which a child might exhibit while in an intensive care unit, such as confusion, crying, anger, and fear. The dimension “Parental Role Alteration” is comprised of aspects of the parental role, which have changed because of the illness, such as separation from the child for long periods of time, not being able to care for the child personally, and not being able to hold the child. The “Sight and Sounds” dimension includes aspects of the immediate physical environment, which parents might see or hear, excluding aspects surrounding their child, such as the steady bleep of monitors and the 76 equipment and machinery. The dimension “Procedures” includes a number of treatment techniques that might be performed while a child is in an intensive care unit. This includes routine procedures such as checking temperature and measuring blood pressure as well as invasive procedures characteristic of acute illness, such as tubes in the child, suctioning, and respirator treatment. Staff Communication is a dimension defined by a number of items describing aspects of parent-staff interactions, such as explaining things too fast and using words that are not understood. Staff behavior encompasses behaviors that are observed by parents but that are not directly related to staff communication, including staff joking and laughing, and the staff acting as if they did not like the child (See Appendix B). Parents are asked to rate the level of stress produced by the items on a five-point Likert- type scale ranging from 0 (not stressful) to 5 (extremely stressful). Psychometric data provided by the instrument developer (Carter & Miles, 1983) showed the test-retest reliability coefficient to be moderate to high (0.73-0.92) for all dimensions except “PICU sights and sounds,” which was relatively low (0.58). The questionnaire is easy to administer and most respondents can complete it in five minutes. The PSS: PICU can be scored using the seven dimensions as subscales and a total PSS: the PICU stress score can be computed using all 37 items. The mean score for each dimension is computed by dividing the sum of the dimension or total scores by the number of items rated 1 or above. Group means are then calculated from individual mean scores. In this study a group mean, rather than the mean score of the individual dimension, was used. The range of scores for each subscale is one to five, providing equality of expected values for comparison purposes (Carter & Miles, 1983). The 77 questionnaire has gone through several revisions resulting in its current form. Content validity was evaluated by five doctorally prepared pediatric nursing faculty for the original study (Miles & Carter, 1983). With regard to internal consistency reliability, Cronbach’s alpha coefficients range from .72 to .99 for the seven dimensional subscales and .95 for the total scale score (Carter & Miles, 1983). Coping Coping was measured by the Coping Health Inventory for Parents (CHIP) (McCubbin, McCubbin, Nevin, & Cauble, 1996). The CHIP is a 45-item checklist designed to assess the types of coping strategies that parents use to manage family life when their child is seriously and/or chronically ill (See Appendix C). The development of the CHIP was based on a process of combining behavior items from previous studies including Caplan (1976), Cobb (1976), Pearlin & Schooler (1978), Lazarus (1966), and parent communication with the health care team and other parents of chronically ill children (McCubbin, 1987, p. 176). The score for each coping behavior ranges from “not helpful” to “extremely” helpful on a 0 to 3 scale. This instrument consists of three coping patterns. Coping pattern Ι is called Family Integration, Cooperation, and Optimistic Definition of the Situation. It is composed of 19 behaviors that focus on strengthening family life and relationships and the parents’ outlook on life with a chronically/critically ill child. Coping pattern ΙΙ is referred to as Maintaining Social Support, Self-Esteem and Psychological Stability. This pattern consists of 18 items that involve the parents’ efforts to develop relationships with others and to engage in activities that enhance feelings of individual identity and to manage psychological tensions and pressures. 78 Coping pattern ΙΙΙ contains eight behaviors directed at understanding the health care situation through communication with other parents and communication with the health care team, which includes the parents’ relationships with health care professionals and other parents of chronically ill children as well as ways to increase their knowledge and understanding of the illness and the mastery of any home-care treatment and prescribed medical regimens (McCubbin & Patterson, 1991). Internal reliabilities (Cronbach’s alphas) for the three coping patterns have been found to be .79, .79. and .71, respectively. According to McCubbin, Thompson, and McCubbin (1996), the three factors/subscales have generally good consistency, with Cronbach alphas of .79, .79, and .71, respectively. Evidence for construct validity is provided by studies of parents with children who have cerebral palsy and cystic fibrosis (McCubbin, 1987; McCubbin, McCubbin et al., 1983). These studies support the original factor structure. In addition, the McCubbin et al. (1983) study provides some evidence of criterion validity for the CHIP by showing that its coping patterns are significantly associated with dimensions of family functioning, as measured by the Family Environment Scale and measures of improvement in their children’s health. Social Support Social support was measured by a shortened version of the Inventory of Socially Supportive Behaviors (ISSB) (Barrera, Sandler, & Ramsay, 1981). The ISSB is a 40-item self-report measure that requires respondents to report on the frequency of receipt of socially supportive transactions in the past four weeks using a 5-point scale. The items are rated from “not at all” (1), to “once every month” (2), “once a week” (3), “several 79 times a week (4), and “every day” (5) (See Appendix D). The responses were summed to obtain a total score. Barrera et al. (1981) reported coefficient alpha on two separate administrations and test-retest reliability of the items ranged from a low of .44 to .92. Factor analysis of the ISSB (Barrera & Ainlay, 1983) suggests that the ISSB has four underlying factors: (a) Directive guidance, including teaching skills, giving feedback and providing advice; (b) Non-directive/emotional support, involving expressions of intimacy, unconditional availability, esteem and trust; (c) Positive social interaction/cognitive information, such as talking about common interests, joking and kidding; and (d) Tangible assistance, including providing physical assistance, shelter, money etc. Although Stokes & Wilson (1984) have revealed a four factor structure, there are some discrepancies and inconsistencies with regard to the factor loadings of particular items. For this study, the researcher used a brief 21-item version of the ISSB that was used by Kaul (1995). Item selection for this form was based on the independent opinions of three professionals (2 nurses and a social worker) who work with mothers of children with CHD on a regular basis. Each of them independently selected 21 items from the original ISSB which they saw as being particularly relevant to this population. Any item on which two of the three agreed was included in the questionnaire utilized in this investigation. Twenty-one items met criteria for inclusion. This shortened version of the scale has a Cronbach’s alpha reliability of .93. The total scale score, rather than the subscale scores, will be used in this study. Family Adjustment Family adjustment was measured by the General Functioning (GF) and Communication subscales of the Family Assessment Device (FAD) (Epstein et al, 1983) 80 (See Appendix E). Although this study uses only two of the Family Assessment Device subscales, this section gives an overview of the FAD. The FAD (Epstein et al., 1983) is a 60-item 4-point Likert self-report questionnaire. The FAD is based on the McMaster Model of Family Functioning (Epstein, Bishop, & Levin, 1987), a clinically oriented conceptualization of families. Family members (over age 12 with a 6th-grade reading level) rate their agreement or disagreement with how well an item describes their family. Lower scores indicate healthy adjustment. Recommended health-pathology cutoff scores are 2 as reported (Miller, Epstein, Bishop, & Keitner, 1985). The FAD is composed of seven subscales based on factor analysis of data obtained from 504 clinical and non-clinical families. Problem solving refers to the family’s ability to resolve problems. Communication focuses on whether exchanges of information among family members are clear and direct. Roles focuses on whether the family has well-established patterns of behavior for handling a set of family functions, such as providing nurturance and support, supporting personal development, managing the family systems and considering whether family tasks are carried out conscientiously by family members. Affective responsiveness focuses on the extent to which individual family members are able to experience appropriate affect over a range of stimuli. Affective involvement is concerned with the extent to which family members are interested in and place value on each other’s activities and concerns. Behavior control assesses the way in which a family expresses and maintains standards for the behavior of its members. The General Functioning subscale assesses the overall health/pathology of the family (Epstein et al., 1983). 81 The GF scale consists of 12 self-report items. The Communication subscale consists of 9 items. The items in the scales are rated from “Strongly Agree” (1), to “Agree” (2), “Disagree” (3), and “Strongly Disagree” (4), and they assess family adaptation. Past research has supported the reliability of the GF and Communication subscales. The Cronbach’s Alpha for GF scale found by Epstein et al. (1983) was .72, and for the Communication subscale was .71. Musil et al (2006) also reported Cronbach’s alphas for the GF scale of .86 and for the Communication subscale α =.71. Additionally, Welcher (1997) used the FAD to measure adaptation of 150 parents of a deaf child. The author reported the Cronbach’s alpha for FAD to be .93. In terms of the concurrent validity of the FAD, it was tested in a study comparing the FAD to the Family Adaptability and Cohesion Evaluation Scale (FACES) and the Family Unit Inventory (FUI). Overall, the study obtained very close correlations between the FAD and the FUI that closely approximated the predicted relationships (Miller et al., 1985). The correlation between the GF subscale of the FAD and the FUI was found to be-.75 and -.61. Mean scores of the two subscales can be used to represent family adjustment. The scores for items describing unhealthy functioning was transformed. The possible range of the scores ranged from 1.00 to 4.00 with higher scores adjustment. Data Management The researcher maintained data consistency and integrity during data collection, coding and entry. As data was collected, it was coded and entered into a computer file. Upon completion of the data entry, the data was examined for coding and entry errors. The accuracy of the data entry was checked in three ways. First, the researcher visually inspected each entry for its consistency. Second, a list of frequencies for all variables was 82 computed to check the erroneous values. Finally, the researcher and a second person inspected the data item by item to assure a better accuracy of the data entry. Each subject is assigned a code, and the subject’s code number is written on each form. A detailed codebook identifies each variable in this study, including an abbreviated variable name limited to six to eight characters, a descriptive variable label, and the range of possible numerical values of every variable was developed for the data file. Only the principle investigator entered all the study data. The researcher used back-up databases after each entry period on floppy disk and in the hard drive. The researcher, as expected in such studies using self reported questionnaires, encountered missing data. .The pattern of missing data is more important than the amount of missing data (Tabachick & Fidell, 2000). There are three types of randomly missing data: missing completely at random, missing at random, and systematic or non-ignorable missing data (Kline, 1998; Musil, Warner, Yobas & Jones, 2002). Identifying the patterns of missing data has a direct connection to the way to most appropriately to deal with the missing observations (Musil et al., 2002). Data that are completely missing at random pose a less serious problem (Musil et al., 2002). Non-random missing values are serious and will influence the study’s generalizability (Musil et al., 2002; Tabachick & Fidell, 2001). In this study, there was some randomly missing data. For the missing data, each item was replaced with an individual mean at the related subscale. Only one case was excluded because the participant left the Coping Health Inventory, the Inventory of Socially Supportive Behavior, the FAD General Functioning and the demographic sheets completely unanswered. 83 The investigator also screened the data for outliers. An outlier is a case with an extreme value on one variable (a univariate outlier), or a strange combination of scores on two or more variables (multivariate outlier) (Tabachick & Fidell, 2001). The researcher used Leverage and Cook’s D values as methods to detect multivariate outliers (Tabachick & Fidell, 2001). Data Analysis The analysis of data were performed using SPSS 11.0 software for Windows. The data analysis was divided into two parts to answer the research questions: preliminary analysis and research questions testing. Pearson’s r correlation, multiple regression and hierarchical multiple regression used to analyze the predictors of adjustment outcome. Preliminary Analysis Preliminary data analysis was performed prior to Pearson product Moment correlation testing and multiple regression analysis. Preliminary analysis included descriptive analysis which was used to examine the accuracy of data by assessing the shape of the distribution (normal, skewness, kurtosis), the missing data, the central tendency ( mean, median and mode), the dispersion (range, variance, and standard deviation) of the scores for each variables. The univariate and multivariate outliers examined also by using descriptive statistics. In addition, the preliminary analysis was conducted to examine and test the assumptions for correlation and multiple regressions. 84 Research Questions Testing After performing the preliminary data analysis, the analyses of data were performed using SPSS version 11.0. Six research questions were answered in this study. Research Question 1: What are the relationships among family and child demographic variables (the parent’s and child’s age, parent’s gender) and family (a) stress; (b) social support; (c) coping; and (d) adjustment? Pearson Product Moment correlation were used to answer whether parent’s age, gender, child’s age, stress, social support, coping and adaptation, the relationship will be examined by using Pearson’s r correlation. The value of statistical significance is an alpha of .05. Research Question 2: Do stress, coping, and social support affect the adjustment of families of children who have heart surgery? Multiple regression analysis was used to answer this research question. The dependent variable was represented by two subscales (FAD General Family Functioning and FAD communication) regressed on the independent variables (Stressful family Life events, Intra-family Strain, the summary score of PSS: PICU,, parental coping (three subscales that present three coping patterns), and social support as measured by the total score of ISSB). Research Question 3: What are the effects of stress, coping, and social support on family adjustment while controlling for the families and the child’s demographic factors (parent’s age, gender, and child’s age)? Two separate hierarchical multiple regressions used to evaluate the effect of family stress, coping, and social support on family adjustment while controlling for “parent’s 85 age” “parent’s gender,” and “child’s age. The independent variables (stressful family life events, intra-family strain, PICU environmental stress, coping, and social support) entered first in the equation. The control variables entered in the last step (parent’s age, parent’s gender, and child’s age). Parental adjustment represented by the General Family Functioning and Communication subscales of FAD served as the dependent variable. Based on the overall R, the amount of variances that account for R2, and the significance of each of the independent variables, the researcher interpret the results. Research Question 4: Does social support moderate the relationship between stress and adjustment in families of children in the PICU after heart surgery? Hierarchical multiple regression analysis used to test for the moderating effect of social support on parent’s adaptation. Before doing multiple regression, “centering” of the independent variables (parental stress, social support) is applied first. Centering is the conversion of the score to a deviation score so that each variable has a mean of zero (Tabachick & Fidell, 2001). Since the interaction terms (e.g. stress x social support) may be correlated to each other, centering is the way to make the high correlation of the interaction term drop (Tabachick & Fidell, 2001). Centering done by subtracting the sample mean from all individuals’ score as suggested by (Hombeck, 1997; Tabachick & Fidell, 2001). The advantage of “centering” is reducing the multicollinearity of the interaction term and this gives more meaningful interpretations of the regression of the independent variables and the outcome variables (Finney, Mitchell, Cronkite, & Moos, 1984). After “centering”, the order of entry of the variables was as follow. The predictor variables (stressful family life events, intra-family strain, and PICU environmental stress) entered in the first step as predictors of the outcome variable (family adjustment). The 86 moderating variable (social support) will entered in the second step. The independent variables do not have to be significant predictors of the outcome variable in order to test for an interaction in the next step (Bennett, 2000). The predictor and potential moderating variable will be multiplied to create interaction terms (Stressful family life events, intrafamily strain, and PICU environmental stress x social support) entered in the third step. Each interaction term will be evaluated separately to see the effect on the dependent variable (adjustment as represented by two measures: FAD general family functioning and FAD communication). If the interaction term explains a statistically significant amount of variance in the dependent variable (parental adjustment), a moderator effect is present (Bennett, 2000). Research Question 5: Does social support have a mediating effect on the relationship between stress and adjustment in families of children in the PICU after heart surgery? To test for the possible mediating effect of social support on the relationship between stress and adjustment multiple regression analysis was used. Three regression equations were used. 1. The first equation test if the independent variables (stress as measured by stressful family Life Events, Intra-family strain, PICU environmental stress) are a significant predictors of the mediator (social support). 2. The second equation will test if the independent are significant predictors of the outcome variable (adjustment). 3. The third equation will contain both the independent variables and the mediator variable entered simultaneously with the outcome variable (adjustment). 87 Two conditions must be met in the third equation if a mediator effect is present: (a) the mediator is a significant predictor of the outcome variable (adjustment), and (b) the direct relationship of the independent variable to the outcome variable is becoming nonsignificant or is less significant than it was in the second equation (Bennett, 2000). Research Question 6: What are the major sources of stress for mothers and fathers when their child is in the PICU following cardiac surgery? Descriptive statistics was used to answer this research question. Protection of Human Subjects Prior to the initiation of this study, the Human Subjects Review Boards of University Hospitals and Cleveland Clinic Foundation approved it. Subjects didn’t exclude on grounds of gender, race, or color. A cover letter, explaining the purpose of the study, the benefits and risks, confidentiality, and requirements for participation were given to each subject with the questionnaire. The subjects informed that their participation is voluntarily and their willingness to participate or not participate will not affect their care and treatment at the hospital. Other than the possible inconvenience of completing the questionnaire, there was no risk involved in participation in this study. However, because of the sensitive nature of the subject of congenital heart disease, the investigator was concerned that addressing such questions could raise sensitive issues for some parents There was no direct benefit to the participants in the study. However, the study provided the parents an opportunity to express their feelings, and this can be a means of getting some emotional relief. The parents’ privacy was protected by having the parents complete the questionnaires in the privacy of the child’s room or a nearby conference room, as desired by the parent. 88 Confidentiality will be safeguarded in the following manner. An identification number was placed on all forms to ensure the confidentiality of the parents, and the master list kept with all the data collection forms in a locked file. Only the investigator had access to those records. Participants in this study were given a verbal and a written description of the risks, benefits, nonparticipation or withdrawal rights, and assurances of confidentiality, anonymity, and protection of privacy in order to protect or minimize the risk of uninformed consent. They clearly informed that the child’s care will not be affected by the decision to participate or not participate in this study and that they can withdraw at any point in the study without any impact on the medical care received at the institution. 89 CHAPTER ΙV Results The purpose of this study is to explore the relationship between family and child demographic characteristics, stress, social support, coping, and adjustment in families who have a child in the PICU after heart surgery. In addition, this study examined whether social support has a mediating or a moderating effect on family adjustment. This chapter presents the study results. The chapter first presents the demographic characteristics of the subjects and a description of the major study variables. Next, analyses for the six research questions are presented. SPSS 11.0 for Windows was used to evaluate all assumptions and to derive the findings. Parents’ demographic characteristics The sample of this study consisted of 74 parents (8 fathers, 66 mothers) of children admitted to the PICU after heart surgery. Subjects were recruited from two hospitals in Cleveland, Ohio: University Hospitals of Cleveland and the Cleveland Clinic Foundation. The demographic characteristics of the subjects are presented in Table 1. Of the parents involved in the study, the majority were female (N = 66, 89.2%). The age of the participants ranged from 18 to 55 years (M = 34.27, SD = 7.54). Participants were predominantly married (68.9%), European American (86.5), and Christian (85.5 %). In terms of education, most of the participants had some college 33.8%; 17.6 graduated from college, 17.6 completed high school, and 10.8 had attended graduate school. Of the mothers, 35.1% were not employed, and 55.4% were employed either full time or part time. However, all the fathers included in the sample (n = 8) reported full time 90 employment status. Parents reported that 97.3% of the children were their biological children, and 1.4% of the children were adopted.

The age of the hospitalized children ranged from .23 months to 143.77 months (M = 31.34 months); 10.8% of the children were newborn; 29.7% were infants, and 24.3 % were under 3 years (see Table 2). 82.4% of families know their child’s diagnosis postnatal.

Descriptions of study variables Descriptive statistics of the study variables are presented in Table 3. The mean score of intra-family strain was 2.3 (SD = 2.1) with a range of 0-9. The mean score of stressful family life events was 1.3 (SD = 1.1), and the number of stressful family life events ranged from 0-5. Because this is a revised version of FILE there is a limited number of published comparative studies. In a study by Musil et al. (2006), which used the same revised version, the authors reported a range of 0-8 on the stressful family life events subscale, a mean of 1.7 and (SD =1.5). The mean score of intra-family strain was 3.7 (SD = 2.7). The Parental Stressor Scale: PICU was used to measure family stress arising from the PICU environment. The mean response on the scale was 2.3 (SD = .6). 95 The scores ranged from 1.00 to 3.8 on a Likert scale that ranged from 0, meaning “not experienced,” to 5, meaning “extremely stressful.” Carter et al. (1985, 1989) reported mean scores with ranges of 2.1 to 3.3 and 2.0 to 3.3, respectively, with the highest scores in the dimension of role alteration. Subscale means and SD of this scale are reported in Table 20 Coping was measured by the Family Coping Health Inventory for Parents (CHIP) (McCubin et al., 1981). Table 3 shows that participants used the three coping patterns in different degrees to cope with their situation. Coping pattern Ι, which involves family integration, cooperation and having an optimistic definition of the situation, was used more often by the parents (M = 43.71, SD = 7.94) as compared to the other two patterns of coping (pattern ΙΙ coping : maintaining social support, self-esteem and psychological stability [M = 24.3, SD = 10.02], and pattern ΙΙΙ coping: understanding the health care situation through communication with other parents and with the health care team [M = 16.6, SD = 4.8]. The scale’s authors (McCubin et al., 1981) reported comparative information which was based on data derived from 107 mothers of children with cardiac disease. The comparative data revealed a mean of 41.8 (SD = 12.4) on pattern I coping, a mean of 31.9 (SD = 7.7) for pattern II coping, and a mean of 14.9 (SD = 4.6) for pattern III coping. In this study, social support was measured by a shortened 21-item version of the Inventory of Socially Supportive Behaviors (Barrera et al., 1981). The participants obtained a mean score of 59.7 and SD = 14.07. This version of the instrument’s range is 21-105. The participants in this study obtained a rage of 29-90, indicating they received a high average level of support from others during the preceding months. The mean of the 96 General Functioning Subscale scores of the FAD for this study was 1.8, with (SD = .5). Compared to means reported in the literature, the families in the current study were similar to Miller et al. (1985) and Byles et al. (1988) studies. The current study’s findings are also in line with findings among grandparents (M = 1.9, SD = .60, n = 486) in a study by Musil et al., (2006). The mean of the Communication subscale scores of the FAD for this study is M = 2.1 (SD = .47). This mean is similar to Musil et al.’s study (2006), which reported a mean of 2.00 (SD = .56, N = 486).

What are the relationships among family and child demographic variables (parent’s and child’s age, parent’s gender) and (a) stress, (b) social support, (c) coping, and (d) adjustment? Pearson’s Product-Moment correlation was used to analyze this question. The value of statistical significance was an alpha level of .05 (see Table 4). Assumptions of normal distribution, level of measurement, and homoscedasticity were met (Tabachnick & Fidell, 2001). In this study, stress was measured from two perspectives: stress arising from intra-family strain and stressful family life events, and stress arising from the PICU environment. Adjustment was represented by two subscales of the FAD (FAD general family functioning and FAD communication). As shown in Table 4, there were significant positive correlations between intrafamily strain and FAD general family functioning (r = .37, p < .01). More intra-family strain was associated with perceptions of poorer family functioning. There was also a positive correlation between intra-family strain and FAD communication (r = .31, p < .01).The more strain there is between a husband and wife, the more problems they have in communication with each other. Stressful family life events had a significant positive correlation with FAD general (r = .33, p < .01). The more stressful family life events that accumulate for the family, the worse their perception of family functioning. Also, there was a positive correlation between stressful family life events and FAD communication (r = .33, p < .01). More stressful events are related to more problems in communication and 98 adjustment as presented by FAD general functioning and FAD communication. Correlation matrix of all major study variables are presented in table 5.

Do family stress, coping, and social support affect the adjustment of families of children who have heart surgery? This question was answered using a liner regression equation. Variables were entered simultaneously into the equation using intra-family strain, stressful family life events, PICU environmental stress, three coping patterns, and social support as the predictor variables. The criterion variables were FAD general family functioning and FAD communication .The results of these regressions are presented in Tables 5 and 6. The regression equation using FAD general family functioning as the criterion variable was significant, F (3.41), p = .00.The variable that had a significant relationship with FAD general functioning is coping pattern I (ß =.21, p < .05). The regression equation using FAD communication as the criterion variable was also significant, F (2.62), p = .02. Stressful family life events had a significant relationship with FAD communication (ß = .22, p < .05).

What are the effects of stress, coping, and social support on family adjustment while controlling for the parent’s and the child’s demographic factors (parent’s age, gender, and child’s age)? FAD general family functioning A hierarchical multiple regression was used to answer this research question. The FAD general family functioning subscale was regressed on intra-family strain, stressful family life events, PICU environmental stress, coping, social support. Both parent and child age and gender were controlled in the second step. Table 8 shows the predictive relationships between the set of predictors and FAD general as the dependent variable. Intra-family strain, stressful family life events, PICU environmental stress, and social support had a significant effect on family general family functioning (F = 3.40, p < .002). They accounted for 26% of the total variance of adjustment. Only one of the regression coefficients was significant: coping pattern Ι (ß = -.30, p < .05). The Coping ΙΙΙ (ß =.25, p <.07) approached but was not, significant. When the demographic variables (parent’s age, child’s age, parent’s gender) were controlled in the second equation, the overall equation remained significant (F = 2.36, p < .01). The three demographic variables accounted for an additional 1% of the variance in adjustment, thereby increasing the total explained variance of adjustment to 27 % (Adjusted R2 = .15). After adding these three variables to the equation, coping pattern Ι was still significant, and coping pattern ΙΙΙ was still approaching the significance level, but not significant (see Table 8). 102 Table 8 Summary of Hierarchical Regression of FAD General on Intra-family Strain, Stressful Family life Events, PICU Parental stress, Coping, and Social Support Controlling for Parent’s and Child’s Demographics (Parent’s Age, Gender, and Child’s Age) Variables B SEB ß Intra-family strain 4.73 .03 .18 Stressful family life events 7.57 .05 .16 PICU environmental stress .16 .10 .20 Coping Ι -2.04 .01 -.30* Coping ΙΙ 4.97 .00 .09 Coping ΙΙΙ 3.00 .01 .25# Social support -3.28 .00 -.08 Intra-family strain 4.61 .03 .18 Stressful family life events 7.27 .05 .15 PICU environmental stress .16 .10 .19 Coping Ι -2.0 .01 -.29 Coping ΙΙ 4.93 .00 .09 Coping ΙΙΙ 2.95 .01 .24# Step 1 Step 2 103 Table 8 Summary of Hierarchical Regression of FAD General on Intra-family Strain, Stressful Family life Events, PICU Parental stress, Coping, and Social Support Controlling for Parent’s and Child’s Demographics (Parent’s Age, Gender, and Child’s Age)(Continue) Variable B SEB ß Child age 1.40 .00 .08 Parents age -4.28 .00 -.06 Child’s gender 6.31 .19 .03 Note.

Parent’s age, gender and child’s age were controlled in the second step. Table 10 shows the predictive relationships between the set of predictors and FAD communication as the dependent variable. Intra-family strain, stressful family life events, PICU environmental stress, and social support had a significant effect on FAD communication (F = 2.46, p <.05). They accounted for 21% of the total variance in communication. None of the variables alone were significant predictors of communication in the first step of the regression. When the demographic variables (parent’s age, child’s age, parent’s gender) were controlled in the second equation, the overall equation was still significant (F=2.03, p <.05). The three 106 variables increased the total explained variance of family communication by 4 % (Adjusted R2 = .13). Also, after adding these three variables into the equation, still no single variable was a significant predictor of communication.

Does social support moderate the relationship between stress and adjustment in families of children in the PICU after heart surgery? In order to examine for a moderating effect of social support on parent’s adjustment (FAD general family functioning, FAD communication), hierarchical multiple regression was conducted. Before conducting the analysis, “centering was conducted with the independent variables (stressful family life events, intra-family strain, PICU environmental stress, and social support). Centering is done by subtracting the mean of each variable from the respondents’ scores to in order to decrease the multicolliniarity between the independent variables. The independent variables are entered in the first step as predictors of the outcome variable (family adjustment as measured by FAD). The moderating variable (social support) is entered in the second step. Three interaction terms (intra-family strain x social support, stressful family life events x social support, and parental stress as measured by the total score on the PSS: PICU scale x social support) were computed from mean-centered scores and entered in the third step. If the interaction term explains a statistically significant amount of variance in the dependent variable (adjustment), a moderator effect is present (Bennett, 2000). Intra-family strain, social support and FAD general As indicated in Table 12,intra-family strain was a significant predictor of general family functioning at in the first step (ß=.37, p <.001). Social support was not a significant predictor of adjustment in the second step, yet intra-family strain remained a significant predictor of adjustment in the second step (ß=.35, p < .001). As shown in Figure 3, the extent to which intra-family strain impact FAD general functioning 111 depending on the level of social support. The interaction term (intra-family strain x social support) was significant at step 3 (ß = -.22, p < .05).

These results indicate that there is no moderating effect of social support between parental stress from the PICU environment and general family functioning.

This indicates that social support is not a moderator between stressful family life events and FAD communication.

Does social support have a mediating effect on the relationship between stress and adjustment in families of children in the PICU after heart surgery? In order to test for a mediating effect of social support on the relationship between stress (intra-family strain, stressful family life events, PSS/PICU) and adjustment (FAD general, FAD communication) three separate regressions were conducted. In the first, stressful family life events was regressed on social support; in the second, intra-family strain was regressed on social support; and in the third, PICU environmental stress was regressed on social support. As shown in Table 17, only one of the regression parameters was significant (intra-family strain). So this is the only variable that will be examined for a mediating effect in the next step. Table 18 Effects of the Independent Variables on the Mediator Variable (Social Support) Independent variables R2 Adjusted R2 F P Stressful family life events .00 -.01 .05 .81 Intra-family strain .07 .06 5.97 .01* PICU environmental stress .04 .02 3.08 .08 In step 2, only intra-family strain was regressed on FAD general family functioning. As shown in Table 19, intra-family strain was a significant predictor of the FAD general family functioning ( ß =-.28*, p <.001). In the third step, both intra-family strain and the mediator (social support) were regressed on FAD general adjustment. Two conditions must be met in the third equation if a mediator effect is present: (a) the 118 mediator is a significant predictor of the outcome variable (FAD general family functioning), and (b) the direct relationship of the independent variable with the outcome variable is becoming non-significant or is less significant than it was in the second equation (Bennett, 2000). As shown in Table 19, these two conditions didn’t hold, so there was no mediating effect of social support on the relationship between intra-family strain and adjustment as measured by FAD general family functioning subscale.

In the third step, both intra-family strain and the mediator (social support) were regressed on FAD communication. Two conditions must be met in the third equation if a mediator effect is present: (a) the mediator is a significant predictor of the outcome variable (FAD communication), and (b) the direct relationship of the independent variable to the outcome variable is becoming non-significant or is less significant than it was in the second equation. As shown in Table 20, these two conditions didn’t hold, so 119 there was no mediating effect of social support on the relationship between intra-family strain and adjustment as measured by the FAD communication subscale.

What are the major sources of stress for mothers and fathers when their child is in the PICU following cardiac surgery? Table 20 shows the mean and SD of the total sample’s (N = 74) scores on the Parental Stressor scale: Pediatric Intensive Care Unit (PSS/PICU). The table shows that the dimension ranked most stressful in the PICU was alteration of parental role (Mean = 2.86, SD = 1.11). The second most stressful dimension was the child’s behaviors and emotions (Mean = 2.68, SD = 1.04). The least listed stressful items were sight and sound in the unit (Mean = 2.01, SD = .81) and behaviors of professional staff in the unit (Mean = 1.49, SD = .73). Table 21 Most Stressful Items Identified by Mothers and Fathers on the Parental Stressor Scale: PICU (N=74) Variable Mean SD Parental role alteration 2.86 1.11 Child’s behaviors and emotions 2.68 1.04 Procedures 2.57 .87 Staff communication 2.48 1.19 Child’s appearance 2.01 .96 Sights and sounds 2.01 .81 Behaviors of professional staff 1.49 .73 121 When mothers’ and fathers’ scores are compared, parental role alteration is still ranked as the most stressful PICU dimension both for mothers (M = 2.86, SD = 1.13) and for fathers (Mean = 2.85, SD = 1.00). Parents ranked their child’s behaviors and emotions differently. While mothers ranked this dimension as the second most stressful dimension in the PICU (M = 1.77, SD = 1.05), fathers ranked this dimension as the 5th stressful PICU dimension with a M = 2.01 and SD = .75. For fathers, the second important PICU dimension was professional staff communication (M = 2.69, SD = 1.58) which came in fourth in mothers’ rankings of stressors. The least stressful PICU dimension for mothers was professional staff behaviors (M = 1.74, SD = .74). The least stressful dimension for fathers was child’s appearance (M = 1.61, SD = .65).

Moderator effect of social support between stressful life events strain and FAD general functioning 124 CHAPTER V Discussion This study was designed to further our understanding of the factors influencing the adjustment of families of CHD children. The conceptual model for the study was drawn from McCubbin and McCubbin’s (1996) Resiliency Model of Family Stress, Adjustment, and Adaptation for the conceptualization of stress, coping, social support and adjustment. The adjustment phase of the Resiliency Model was chosen to best describe the family experience of the study population. Having reviewed the literature, it was concluded that certain gaps in the knowledge existed, and these are what this research attempts to fill. There has been no nursing research that addresses the topic of stress, coping, social support of families of children with CHD who are in the PICU after heart surgery. While having a child with CHD has been shown to be a stressful event, little empirical research has been reported that investigated all of these variables in one study. Data analysis involved descriptive statistics, Pearson Product-Moment correlation coefficients, multiple regression and hierarchical multiple regression models to examine moderating and mediating models. This chapter presents a discussion and interpretations of the research findings. It is organized around the major concepts investigated: stress, coping, social support and adjustment. An evaluation of the study model is also provided. Study limitations as well as implications for nursing practice and policy, as well as a summary and recommendations for future research are presented. 125 Stress Stress in this study was conceptualized as encompassing the stress arising from intra-family strain, stressful family life events (McCubbin et al, 1996) and dimensions of environmental stress in the PICU (Miles, Carter, Hennessey, Eberly & Riddle, 1989). With regard to stress due to the accumulation of intra-family strain and stressful family life events, both subscales had a significant relationship with both of the outcome variables of family adjustment – the FAD General Family Functioning and FAD Communication subscales. These results indicate that family stress that arises from intrafamily strain due to increases in conflicts between husband and wife, the number of tasks that don’t get done, difficulty managing children, and conflict with in-laws or relatives contributes to unhealthy general family functioning and poor communication and interaction within the family. In addition, increases in the number of stressful family life events a family has experienced in the past year, such as a child’s become seriously ill or injured, a family member having stopped working or lost his job, incidence of physical and/or psychological aggression in the family, and a family member who has left home or moved back home, leads to poor general family functioning and poor communication within the family. Because there is a paucity of studies investigating the relationship between stress and adjustment in children with congenital heart disease, studies of other populations were reviewed. Failla and Jones (1991) found that greater family stress, as measured by FILE, was associated with lower levels of satisfaction with family adjustment for mothers of children with developmental disabilities. Thompson, Gil, Gustafson, George, Keith, 126 Spock & Kinney (1993) reported that lower levels of maternal stress were associated with good maternal adjustment in mothers of children with cystic fibrosis. Other studies have also provided evidence that stress is related to family adjustment and adaptation (Leske & Jiricka, 1998; Hill, 1993). The results of this study indicated that family stress from the PICU environment had no significant relationship with the outcome variable (adjustment as measured by FAD general family functioning and FAD communication). The lack of a significant relationship between family stress as measured by the PSS/PICU and family adjustment is consistent with the results of other studies. Leske and Jiricka (1998) found that prior stressors – as measured by the FILE – rather than the actual stressor event affect a family’s experience in the PICU and may influence family adjustment. In addition, these results may be attributed to differences in the structure of the samples. Samples in previous studies included parents of children with a mixture of diagnoses, while the current study limited the child’s diagnosis to CHD. A further reason why there is no significant relationship with adjustment may be due to the small sample size included in this study. The correlation between the PSS: PICU scale and adjustment in this study approaching significance. Maybe with more participants, this correlation will be significant, and the relationship will be more clear. Of interest are differences in the degree of stress perceived by mothers and fathers. In spite of the efforts exerted to recruit more fathers in the study to understand their experience, only 8 fathers participated in the study. The findings of this study revealed that both fathers and mothers reported that the overall PICU experience was stressful for them, and mothers had higher mean scores than did fathers on all seven of 127 the PSS: PICU scales. The dimension of parental role alterations was reported the most stressful among the PSS: PICU dimensions for both fathers and mothers. The top stressors for parents under this dimension were “not being able to hold my child” and “not taking care of my child by myself.” This finding is consistent with the results of a number of other studies, namely Miles et al. (1985), Eberly et al. (1985), Miles et al. (1984), Board (1994), Curley & Wallace (1992), and LaMontagne & Pawlak (1990), who found that the dimension of parental role alterations has been the most stressful of the PSS:PICU dimensions for parents. These results were interesting because, historically, items in this dimension have been areas where limits have been set by hospitals in terms of visitation hours and situations where parents have a sense of loss of control or helplessness. But now, with the changes in philosophy of care that encourage staff to include parents in caring for their children, parental role alteration was not expected to still be the most stressful aspect of the PICU experience for families. This result contradicts the results of Youngblut, Brooten & Kuluz (2005), who found that the top stressor for parents of children in the PICU were sight and sounds dimensions. Mothers and fathers differed on their rating of the second most stressful dimension of the PICU. A child’s behaviors and emotions were ranked as the second most stressful area for mothers of CHD children in this study. Mothers may be frightened by some of the behaviors their child displays. The most stressful items in this dimension for mothers were their child’s being afraid, acting or looking as if in pain, whining, or crying. These results was congruent with the results of studies by Carter, et al. (1985), Miles, et al. (1989), Youngblut, et al., (2005), and Johnson, Nelson, & Brunnquel (1988), 128 who found that the children’s behaviors and emotions sub-scale was an area of high stress for mothers. For fathers, the second most stressful area was staff communication. Fathers were stressed by doctors’ and nurses’ ways of communicating such as explaining of things too fast, using words they don’t understand, not telling them what is wrong with their child, and telling them different and conflicting things about their child’s health condition. This result contradicts the results of Board (2004), who find that staff communication was the least stressful scoring dimension in their study of 15 fathers of children in the PICU. The third ranked stressor was the same for fathers and mothers. Both fathers and mothers ranked procedures done to the child as a stressful aspect of their PICU experience. Tubes in my child were identified by 98% of the participants as the most stressful procedure under this dimension. This result supports previous PICU research with fathers (Board, 2004). The least stressful area for parents concerned the behaviors of the professional staff. This subscale included items that describe the manner in which health care professionals deal and interact with family members during their PICU stay. Miles (1979) found that parental stress levels increase when the professional staff looks formal, isolated and preoccupied. Congruent with findings reported by Heuer (1993), parents in this study reported the staff behavior subscale as being non-stressful. Differences in the top stressors between this study and previous studies may be attributed to the differences in the structure of the samples. Samples in previous studies included parents of children with a range of diagnoses, while the current study was limited the child’s diagnosis of CHD. Knowing how parents’ reactions change by 129 diagnosis could provide greater direction for health care professionals in correctly addressing parents’ stressors (Youngblut, et al. 2005). Also, the current study’s results with respect to high levels of parental stress related to the overall PICU experience and the parents’ inability to do things for their children as well as their fear about their child’s future, and these are more obvious results in parents of children who have children in the PICU, as opposed to parents of children in other units of the hospital. Parents of children in the PICU are more stressed than parents of children in general care units and non-hospitalized children. Berenbaum and Hatcher (1992) reported that in comparison to parents in the general care unit, parents of children in the PICU were significantly more depressed, anxious, confused and angry than parents of children in the general pediatric and surgical units and parents of non-hospitalized children. These results were also supported by Board (2004), who found that fathers of children in the PICU are more stressed than fathers of children in the general care unit. In a cross-sectional, comparative study, Youngblut and Lauzon (1995) compared 27 families whose child under 5 years old had been hospitalized in the PICU and general care unit. Results showed that families of children in the PICU perceived greater severity of their child’s illness and lower adaptability. Balluffi et al. (2004) investigated the prevalence of both acute and posttraumatic stress disorders in parents whose children were admitted to a PICU. The results indicated that most of the parents who participated in the study met the criteria for posttraumatic stress disorder. This difference in stress between parents of children in the PICU and parents of children in other hospital units might not be surprising given the severity of the children’s conditions while in the PICU and the treatments that are needed to care for these children. Children in the PICU may 130 have many invasive procedures and different medical devises that produce noise and make the child look severely sick, and they may also experience pain from this monitoring which increases the perception of stress for their parents (Board, 2004). Coping In this study, coping was measured by the Coping Health Inventory for Parents (CHIP), which is used to assess parents’ appraisal of behaviors they are presently using to manage family life when they have a seriously or chronically ill child (McCubbin et al, 1996, p. 432). The CHIP is composed of three coping patterns: Coping pattern I: maintaining family integration, cooperation and an optimistic definition of the situation; Coping pattern II: maintaining social support, self-esteem, and psychological stability; and Coping pattern III: understanding the health care situation. The results of this study indicate that the mean score for the total CHIP scale was 84.10, and scores ranged from 8 to 120. This was higher than that reported in the study of parents of children with cardiac disease (M= 82.0) of McCubbin et al. (1996). The mean score for pattern I of the CHIP was 43.76; for pattern II it was 23.38, and for pattern III, it was 16.50. Mean scores of pattern II and III were lower than in the McCubbin et al. (1996) study (M = 42.85; M = 31.29). These results revealed that families in this study used pattern I for coping more than the other two coping patterns. Ptacek (2003) mentioned that people use different coping strategies in relation to the situation. In Savarsdottir and McCubbin’s (1996) study of coping strategies among parents of children with congenital heart disease, parents found it more useful to them to use coping pattern III, which contains behaviors directed at understanding the health care situation and the parents’ relationships with health care professionals and other parents as a way to cope with their child’s disease. Rodrigue et al. 131 (1997) examined coping patterns in 27 mothers of children undergoing heart, liver, bone marrow, or kidney transplantation. Following transplantation, mothers reported that they used coping strategies to maintain family integration (coping pattern I) and to understand the child’s medical situation (coping pattern III). The relationships between coping and other variables in the study were also examined. There was a positive moderate correlation between family coping pattern I (using family integration, cooperation and optimistic definition of the situation) and social support. This indicates that as a family perceives more support, it enhances their ability to uphold family integrity, cooperation and establish an optimistic attitude. Tak and McCubbin’s (2002) study of the relationship between family coping and social support in parents of children with congenital heart disease is consistent with the results of this study. There was a significant negative relationship between stressful family life events and coping pattern II. The greater the accumulation of stressful life events, the less the ability of parents to use social support, self-esteem and psychological stability as a coping behavior. This result may be attributed to different factors; for example, due to the accumulation of stressful events, families may have no time or opportunity to access social support. Also, since the study was conducted during a child’s hospitalization in the PICU, parents may need time to settle into the experience before they can assess the support resources available. Chesler and Barbarin (1984) found that families may have difficulty seeking help in the midst of crises. The event of cardiac surgery and the child’s admission to the PICU could be considered a family crisis, and parents need time to adjust to it before trying to seek social support. It is also possible that the parents did have 132 the time to access social support systems, but these resources become depleted over time. This might be particularly true for parents who have older children with CHD. In addition, these parents experience high levels of stress due to the accumulation of stressful family life events. LaMontagne et al. (1992) found that highly anxious and stressed parents sought less social support at the time of their child’s admission to the PICU. Consistent with previous research, fewer emotional and cognitive supports were found among high stress families and individuals (Endler & Parker, 1990; Lazarus, 1993). The results of this study revealed a significant negative correlation between parental stress that arises from the PICU environment as measured by PSS/PICU and the parents’ abilities to use pattern ΙΙ coping (maintaining social support, self-esteem and psychological stability). These parents are dealing with multiple different stressors at the same time. They deal with stress arising from the accumulation of stressful family life events and the intra-family strain that has happened in the past year and also with the immediate stress arising from having a child in the PICU after cardiac surgery. Lepore & Evans (1996) indicated that coping strategies directed toward one stressor are exaggerated and affected by the extent to which a person is also coping with other stressors. Individuals who must cope with many stressors at the same time are likely to have significantly fewer coping resources with which to meet the challenges posed by series of stressful events (Ptacek, 2003). Social Support One objective of this study was related to the testing of two models, the moderating and mediating models of the effect of social support, in predicting adjustment 133 from stress. In this study, the moderator and mediator effects were tested as described by Baron and Kenny (1986). The findings suggest that social support has a moderator effect in relation to stress and family adjustment as measured by General family functioning subscale of the FAD. A moderator is a variable that affects the direction and/or strength of the relation between an independent or predictor variable and a dependent or criterion variable (Baron and Kenny, 1986, p.1174). In such a model, social support acts as a moderator, specifying the conditions under which the family will be adjusted. Cohen and McKay (1984) mentioned that social support as a moderator served as a stress buffer by influencing individuals’ interpretations of stressors and knowledge of coping strategies. When families are exposed to high levels of stress, there will be interaction between the high stress experienced by the family and social support. This result is congruent with the results of several studies that support the moderator model of social support between stress and different outcome variables, such as family adjustment and adaptation, psychological distress, depression and marital adjustments (Cohen & Wills, 1985 ; Cohen, 1987; Dunn, Burbine, Bowers, Tantleff-Dunn, 2001; Ievers, et al., 1998; Pengilly & Dowd, 2000; Pot, Deeg & Dyck, 2000; Roos,; Speechley & Noh, 1992). In contrast, a mediating model assumes that social support functions as an intervening variable between the stressor and outcome (Quittner, Glueckauf, & Jackson, 1990). Changes in the level of social support might in turn affect individuals’ adjustment levels. Social support as a mediator does not specify the conditions under which stress and adjustment are linked, but rather it outlines the processes through which stress affects adjustment (Baron & Kenny, 1986). In the present study, the condition of the direct relationship of stress to adjustment is becoming non significant was not met, so there is 134 no support for the mediating model of social support. This result may be because a mediational hypothesis implies a causal order that is difficult to test with cross-sectional data. The present results are consistent with the majority of studies that have tested and failed to find evidence for the mediator role of social support (Tak, McCubbin, 2001). Adjustment In this study, family adjustment was the conceptual outcome variable. Family adjustment was measured by using two subscales of the FAD: the General Family Functioning subscale and the Communication subscale. The mean score of parents on the general family functioning subscale was 1.85. The mean score of parents on the communication subscale was 2.18. The cut-off score for this scale is 2.00 as described by Miller et al (1985). This cut-off score is described as unhealthy by Miller et al (1985, p. 353). In this study 28 parents (37%) reported scores in the unhealthy range on the general family functioning subscale, and 45 (63%) of the parents reported scores in the unhealthy range on the communication subscale. This result is congruent with the results of Board and Rayan-Wenger (2002), who examined the long-term effects of PICU hospitalization on family functioning. Three groups of families were studied: those with children in a PICU, those with children in a general care unit, and a comparison group of parents with non-hospitalized children. The families in the study were followed-up for 6 months after the children’s illness. The results showed that families who have children in the PICU perceived themselves as more dysfunctional than families in the other groups. The effects of the stress, coping, and social support on family adjustment were tested by using multiple regression analysis. The result of regression analysis indicated that of all the independent variables in the model, pattern I coping made the most 135 significant contribution to predicting general family functioning. Previous research has yielded equivocal results with respect to the association between coping and adjustment. As in the literature on stress, differences in conceptualizations and measurement tools make comparisons among studies challenging. While some studies have found that coping was a predictor of adjustment (Frey et al., 1989; Reider ,1989 ; Kosciulek ,1993 & 1994; and Lin, 1998), other studies found no association (Hill ,1993; Phipps & Droter ,1990). A stressful family life event was the strongest predictor of the communication subscale. These results corroborate the findings of Kaul (1995), who found that the overall number of negative stressors a mother of a child with congenital heart disease experienced during the past year proved to be a significant predictor of maternal adjustment among CHD children. Social support did not predict family adjustment. These findings were unanticipated as there is evidence in the literature (Lesk & Jiricka 1998; Musil, et al 2006; Uzark et al. 1992) to show that social support is an important factor in adjustment and family functioning. These results may be attributed to the sample size. The correlation between social support and adjustment in this study approaching significance. Maybe with more participants, this correlation will be significant, and the relationship will be more clear. A further reason for the differences may be related to sample characteristics and measurement. The previous studies used families with mixed diagnoses and different measures for social support. One study, Kaul (1995), used a sample of CHD parents and used the same measure of social support used in this study 136 and found that social support as measured by ISSB does not predict adaptation in mothers of CHD children. The effects of stress, coping, and social support on family adjustment after controlling for parent’s gender, age, child’s age were examined by hierarchical multiple regression analysis. Although none of the independent variables alone was a significant predictor of family adjustment, all together, the variables had a significant incremental variance in adjustment. Adding more control variables to the model explained more variance in adjustment. Parents who have children with no previous heart surgery, who were married, and who have a male child adjust better to their child’s disease. Findings of the Study and the Resiliency Model of Stress, Adjustment, and Adaptation The framework used for this study was based on the adjustment phase of the Resiliency Model of Stress, Adjustment, and Adaptation (McCubbin et al., 1996). In this model, the accumulation of stressors, coping, and resistance resources (social support) all impact family adjustment. Together, the variables in the model accounted for 28% of the variance in family adjustment. Coping was the predictor that made the most significant prediction of general family adjustment while negative family life events made a significant prediction of the communication subscale. These results support the premises of McCubbin et al. (1996), which suggest that the pile-up of stress arising from the accumulation of stressful family life events and coping are very important factors in the adjustment of parents who have chronically ill/or critically ill children. 137 Limitations A non-probability convenience sample (n= 74) was used, consisting of parents of CHD children in the PICU after heart surgery. The use of a convenience sample may weaken the generalizability of the study results since a convenience sample reflects a specific, targeted group, as opposed to a random sample that may potentially reflect the general population of parents of children with CHD. Also, the sample size was relatively small (n= 74). This small sample size may have obscured significant effects or relationships that otherwise may have occurred in a larger sample. A larger sample would have made the study stronger. In addition, the use of a cross-sectional design was also a limitation. Relationships such as causal relationships between the study concepts, the moderating and mediating effects of social support on the relationship between stress and adjustment might have been better explained by a longitudinal study. However, despite these limitations, the findings of the current study have important implications for nurses and other professionals who work with families of CHD children. Implications of the Study for Practice The dynamics of family stress, coping and adjustment must be understood in order to plan effective nursing interventions. Intervention studies should be developed based on a solid foundation of knowledge. Exploring family’s adjustment during a child’s PICU hospitalization will provide researchers with a more substantive basis for developing intervention studies for the period immediately following children’s surgery. Nursing interventions aimed at facilitating coping and minimizing the negative impact of this stressor may have a positive influence on the family’s ability to adjust to the event 138 (Pinelli, 1997). Through early detection of parents who may be at risk for relationship deterioration or family disorganization, health professionals can intervene with preventive strategies. The role of nursing can be viewed as assisting families during the process of adjustment (Pinelli, 1997). The results of this study show that parental role alteration was one of the most important dimensions for both fathers and mothers when their child was in the PICU. Nurses need to understand that parental role is very important to parents. Nurses should encourage parents to provide nursing care and encourage them to hold their child when possible. This may help parents feel more in control of other aspects of the critical care situation and thus be better able to help their child in crisis. As noted, coping accounted for the largest portion of the variance in family adjustment. Such a finding is important and has implications for practice. In practice, a comprehensive understanding of how positive family coping strategies influence family adjustment is needed. Such understanding should also include examining challenges that occur in life due to life events as well as family coping and adjustment differences. Understanding the nature of parents’ stress, coping, social support, and the effect of these variables on the parents’ adjustment allows for the development and implementation of specific nursing interventions for this special population. Nurses can play a vital role as a resource that helps parents manage and cope with their crisis situation because providing support and guidance to families in their adjustment to their child’s illness is an important component of health promotion (Kruger, 1992). In addition, scientific knowledge gained about stress, coping, social support and adjustment 139 will form a relevant and substantive base for nursing practice as well as for further theory development. Theory Development In nursing, stress, coping, social support and adjustment are concepts relevant to the development of a body of nursing knowledge. Roy (1984) described nursing’s perspective as focused on those “processes by which persons positively affect their health status” (p. 266). Stress theory was the predominant theoretical perspective underlying the research on parents and family responses. This research is based on McCubbin and McCubbin’s (1996) resiliency model, and testing this model with this population provides support for the model’s validity in dealing with this population, and this can expand the usefulness of the model. Implications of the Study for Future Research Based on the findings of this study, several recommendations for future research are offered. Data were collected at only one point in time. It is possible that responses may change over time. Longitudinal research could further clarify the concepts examined in this study by revealing cause/effect relationships. Plus, longitudinal research could identify some of the markers of good or poor adjustment that persist over time. Future research could also be improved by measuring some of the variables in a different way. All of the measures employed in the current study were self-reported and hence depended upon families’ perceptions. For future research, a triangulation study using both the instruments in this study and an interview to elicit qualitative data might be productive. 140 One of the main purposes of current and future research in this field is to develop interventions which can assist families who are raising a child with congenital heart disease. Results of the present study suggest certain types of interventions that may improve family adjustment. For example, life events stress was shown to have a significant relationship to family adjustment. This suggests that it might be useful to teach families stress management techniques to help deal with general life stress. One technique that might be useful and can be applied by the researcher in future research is called the nursing mutual participation model of care (NMPMC) developed by Curley and Wallace (1992). The NMPMC is an intervention aimed at facilitating the parents’ ability to reduce their own stress; Curley and Wallace (1992) also used it in the PICU, but their population consisted of parents of children with different diagnoses. The sample in this study was drawn from two sites in the United States. It is unknown how these families differ from others throughout the United States or the world. This study could be replicated with a larger group of families from many sites, or a comparative study with Egypt or any other country could be performed. Random sampling of families would also aid in the generalizability of the results. Replicating the study in Egypt with a larger, random, more diverse sample, and comparing the two studies will give more knowledge regarding the differences in conceptualizing these important concepts across countries, and it would provide a basis for intervention studies. Additionally, in spite of trying to include more fathers in this study, there were only 8 fathers included. The inclusion of more fathers is also a prime topic for future research. 141 Conclusion In sum, this research extends our understanding of parenting stress, coping, social support and adjustment in several ways. In addition to the emphasis on the importance of assessing different kinds of stressors – and not focusing only on the current stressors families are experiencing – the findings underscore roles of coping and social support in the relationship between stress and adjustment. More research identifying the stressors experienced by families of CHD children needs to be done. A comprehensive understanding of how positive family coping strategies influence family adjustment is crucial. Such understanding should also include examining challenges occurring in life due to life events as will as family coping and adjustment differences between fathers and mothers. 142 Summary The purpose of this research was to explore the relationship between family and child demographic characteristics, stress, coping, social support and adjustment in families who have a child in the PICU after heart surgery. Seventy-four parents (8 fathers, 66 mothers) participated in the study. McCubbin and McCubbin’s Resiliency Model of Family Stress, Adjustment and Adaptation provided an organizing framework for the study. Findings of this study indicate that stress due to the accumulation of intra-family strain and stressful family life events contributes to perceptions of poorer family functioning and poor communication and interaction within the family. Both fathers and mothers reported that the overall PICU experience was stressful for them and rated their parental roles and their child’s behaviors and emotions as the most stressful dimensions of their PICU experience. Parents are frightened by some of the behaviors their child displays, such as being afraid, acting or looking as if in pain, and whining, or crying. The least stressful area in the PICU for parents concerned the behaviors of the professional staff. The participants in this study used the three coping patterns of CHIP in different degrees to cope with their situation. Coping pattern Ι, which involves family integration, cooperation and having an optimistic definition of the situation, was used more often by the parents as compared to the other two patterns of coping (pattern ΙΙ coping: maintaining social support, self-esteem and psychological stability; and pattern ΙΙΙ: understanding the health care situation through communication). Also, the findings indicated that the greater the accumulation of stressful family life events and the greater 143 the stress from the PICU environment, the less the ability of parents to use social support, self-esteem and psychological stability as coping behaviors. In this study, family adjustment was the conceptual outcome variable. Family adjustment was measured by using two subscales of the FAD: the General Family Functioning subscale and the Communication subscale. In this study, 28 parents (37%) reported scores in the unhealthy range on the general family functioning subscale, and 45 (63%) of the parents reported scores in the unhealthy range on the communication subscale. The effects of stress, coping, and social support on family adjustment were tested using multiple regression analysis. The result of the regression analysis indicated that of all the independent variables in the model, pattern I coping made the most significant contribution to predicting general family functioning. Adding more control variables to the model explained more variance in adjustment. Families who have children with previous heart surgery, who were married, and who have a male child adjust better to their child’s disease. Although social support did not predict family adjustment in this study, it worked as a moderator variable between intra-family strain, stressful family life events and FAD general family functioning. 144 Appendix A Family Inventory of Life events and Change (FILE) Directions: Over their life cycle, all families experience many changes as a result of normal growth and development of members due to external circumstances.
