The typical informal caregiver is female, either a spouse or adult child of the care recipient, and seldom shares the responsibilities of caregiving with other family members. The spouses worry about the ill relative, but also about what consequences the disease might have for their own life. The worries seem to vary with gender and disease. There are, to our knowledge, few previous longitudinal studies that have focused on gender differences among spouses of stroke patients. Objectives: To explore gender differences among spouses in perceived psychological well-being and general life situation, during the first year after the patients’ stroke event. Design: Longitudinal study with three assessments regarding psychological well-being and general life situation during 1 year. Settings: The study took place at a stroke ward, Stockholm, Sweden. Participants: Consecutively 80 female and 20 male spouses of stroke patients admitted to a stroke unit participated. Methods: Data were analysed using analyses of variance. Results: Female spouses have a negative impact on psychological well-being, while male spouses have a lower occurrence of emotional contacts in their social network. Consistently, the female spouses reported lower quality of life and well-being than the male spouses. Conclusions: This study generates the hypotheses that there are gender differences among spousal caregivers of stroke patients; female spouses are more negatively affected in their life situation due to the patients’ stroke event than the male spouses. It is important to take the individual differences under consideration when designing a nursing intervention, to meet the different needs and demands of male and female caregivers.

Keywords: Gender; Nursing; Life situation; Spouse; Stroke; Well-being What is already known about the topic? home (O’Connell et al., 2003; O’Connell and Baker, 2004; Ekwall et al., 2004). The informal caregivers perceive lack of choice to take on the role of care giving, receiving little or no preparation for the caregiving role at home. The typical informal caregiver is female, either a spouse or adult child of the care recipient, and seldom shares the responsibilities of caregiving with other family members. In several studies, caregivers of stroke patients report reduced social life, upset household routines, sleep disturbances, and a great burden of care. What this paper adds Female spouses have a negative impact on psycho logical well-being, while male spouses have a lower occurrence of emotional contacts in their social network. Consistently, the female spouses reported lower quality of life and psychological well-being than the male spouses. It is important to take the individual differences under consideration when designing a nursing intervention, to meet the different needs and demands of male and female caregivers, and the interventions should focus on individual support, so that the caregivers can adapt to their new role and be comfortable and effective as informal caregivers. 1.1. Consequences of stroke Stroke is one of the most disabling chronic diseases in the adult population, with severe consequences for both patients and their families. With time, the burden of informal care giving contributes to physical, psychological and social stress among the informal caregivers, leading to depression, anxiety and decline in the quality of life (Scholte op Reimer et al., 1998; Dennis et al., 1998). In several studies, caregivers of stroke patients report reduced social life, upset household routines, sleep disturbances, and a great burden of care (Thommessen et al., 2001; Boter et al., 2004; Scholte op Reimer et al., 1998). Living with a person, affected by a chronic illness, is often characterized by a reduced sense of individual freedom and increased sense of responsibility. The informal care often takes a great amount of time and energy, and may cause overwhelming feelings (Öhman and Söderberg, 2004). The spouses not only worry about the ill relative, but also about what consequences the disease might have for their own life, and the worries seem to vary with gender and disease (Kuyper and Wester, 1998). The typical informal caregiver is female, either a spouse or adult child of the care recipient, and seldom shares the responsibilities of care giving with other family members (McCann and Christiansen, 1996). 1. Introduction 1.3. Theoretical framework Annually, approximately 15 million people suffer from stroke worldwide (Mackay and Mensah, 2004). In Sweden approximately 30,000 people suffer from stroke every year, of which some 20,000 for the first time (Riks-stroke, 2003). The disease is the leading cause of death worldwide, and one of the most disabling chronic diseases in the adult population, with severe consequences for both patients and their families (Mackay and Mensah, 2004). The health care system’s trend of reducing the length of the patients’ stay in hospitals incurs several problems, such as that the informal caregivers perceive lack of choice to take on the role of care giving, and they often receive little or no preparation for the caregiving role at In Sweden, an extensive part of the care provided to elderly persons is by informal caregivers (Hellström and Hallberg, 2001). An informal caregiver is a person caring for the next of kin. In this care the concept consists of three words: ‘‘informal’’, indicating that the care is given outside the frames of the formal healthcare system; ‘‘care’’, which is what a person does to help another person; and ‘‘giver’’, which refers to the person giving this help. However, the concept of informal caregiving also means something more than just a caring person; it implies that it is based on relationships and that it is voluntary (Ekwall, 2004). Parker expresses that ‘‘all the factors which transform an impairment into a disability also tend to transform family members and ARTICLE IN PRESS J. Larson et al. / International Journal of Nursing Studies 45 (2008) 257–265 friends into informal carers’’ (Parker, 1992). In this paper, the informal caregivers are the spouses of the stroke patients, and spouse is defined as a person living in the same household as the stroke patient i.e., the main informal caregiver. Many attempts have been made to define the term ‘‘Quality of Life’’ (QoL); however, most researchers agree that QoL is a multidimensional construct (Fayers and Machin, 2000). The definitions of QoL are often linked to health and emphasize such components as happiness, personal well-being, life satisfaction, and impact of illness on social, emotional, occupational, and family domains. The World Health Organization Quality of Life Group (WHOQOL, 1993) defines QoL as the individual’s perception of his/her position in life in the context of the culture and value systems in which they live and in relation to their goals, expectations, standards, and concerns. The overall QoL can be described as the dynamic interaction between the external conditions of the individual’s life and the internal perception of those conditions (Browne et al., 1994). Assessment of QoL may be included in randomizedcontrolled studies, to identify those aspects of QoL that may be effected by the therapy or trials that are expected to improve QoL (Fayers and Machin, 2000). Family members are the main source of support for adults, making them an important part of one’s social network (Hellström and Hallberg, 2001). To be able to obtain social support, having a social network is essential. Social network can be defined as the quantity and density of a person’s social relationships, i.e., the number of persons available and included in the social network, and the closeness in the relationships (Hall and Wellman, 1985). Social support can, in the case of being an informal caregiver or patient, be obtained from healthcare personnel as well as from the social network. 259 psychological well-being and general life situation, during the first year after the patients’ stroke event. 2. Method 2.1. Sample and setting Before the study was conducted, a pilot study including five spouses was made, to evaluate the feasibility of the battery of questionnaires, and the time consumed to fill out the questionnaires. The spouses had no difficulties to fill out the questionnaires, and the time spent varied between 30 and 40 min. During the time period November 2000–July 2002 approximately 500 patients were discharged from a stroke unit in Stockholm, Sweden to their own homes after the stroke event, and of those 253 patients were living with a spouse, i.e., 253 consecutive spouses of stroke patients were eligible for this study. After informed consent from the patients, the spouses were approached in connection with the patient’s discharge from hospital regarding participation in the study. A self-selected sample (40%), consisting of 80 female and 20 male spouses, consecutively accepted the invitation to participate. The most common reason for non-participation among both the men (22%), and the women (24%), were their own illness. A comparison between the non-participants and participants is described elsewhere (Larson et al., 2005). The spouses were followed with assessments at baseline (at inclusion in the study, after the patients’ stroke event), and after 6 and 12 months. Internal dropouts over time consisted of eight women and one man. 2.2. Measurements 1.4. Gender perspective Female caregivers perceive emotional support, behavioural management, and carrying out household tasks as significantly more time-consuming and difficult than male caregivers, and they also express frustration in response to the stroke regarding taking care of their partner. Male spouses deal with changing roles due to the stroke event, and learn new skills and behaviours as they take over tasks that women traditionally perform (Pierce and Steiner, 2004; Robinson-Smith and Mahoney, 1995). There are, to our knowledge, few previous longitudinal studies that have focused on gender differences regarding the life situation among spouses of stroke patients. 1.5. Aim The aim of the present study was to longitudinally explore gender differences among spouses in perceived The collected background data included age and sex of the spouse and patient, and medical history of the spouse. To gain a deeper knowledge of the spouses’ psychological well-being and general life situation, we also included assessments that could be seen as a part of the main concept. The present QoL was measured with a visual analogue scale, consisting of a non-numerical vertical line (100 mm) with verbal extreme point markers, ‘‘the worst possible quality of life’’ (0 mm) and ‘‘the best possible quality of life (100 mm).’’ The spouses were asked to mark their present QoL (Ahlsiö et al., 1984). This general measurement of QoL was chosen due to the possibility for each respondent to make their own decision of what is included in the definition of QoL. The patient’s level of self-care was proxy assessed by the spouse with the Barthel Index (Mahoney and Barthel, 1965). This scale evaluates basic activities of ARTICLE IN PRESS 260 J. Larson et al. / International Journal of Nursing Studies 45 (2008) 257–265 daily living, such as feeding, grooming, transfer, dressing, toilet use, bathing, walking, incontinence of bowel and bladder, and stair walking. The ADL items scores from 0 (complete functional impairment) to 100 (complete functional independence). Cronbach’s a coefficient was in the present study 0.91. Well-being was measured with the short form of Bradley’s Well-being Questionnaire, consisting of three 4-item subscales: negative well-being, energy, and positive well-being. The overall scale, general well-being, is based on these three subscales (Bradley, 1994). The total score of general well-being ranges from 0 to 36, and each subscale ranges from 0 to 12, the higher the score, the better perceived well-being. The internal consistency reliability for the three subscales and the general wellbeing in the present study was 0.85, 0.78, 0.89, and 0.87, respectively, as measured with Cronbach’s a coefficient. The Well-being Questionnaire has earlier been tested in a Swedish setting by Wredling et al. (Wredling et al., 1995). Life situation was measured with the Life Situation Among Spouses after the Stroke event-questionnaire (LISS), consisting of 13 questions, in four subscales: worries, powerlessness, personal adjustment, and social isolation. The total score ranges from 13 to 65 points, where the score of 65 is describing a very good general life situation, and 13 is the lowest score, describing the worst possible life situation. Cronbach’s a coefficient showed internal consistency reliability for the four subscales and the total scores 0.86, 0.86, 0.84, 0.86 and 0.80, respectively, in the present study (Larson et al., 2005). The health state was evaluated with the graded visual analogue scale part of the EuroQoL-instrument which ranges from 0, ‘‘worst imaginable health state,’’ to 100, ‘‘the best imaginable health state’’ (EuroQolGroup, 1990). This general measurement of health state was chosen due to the possibility for each respondent to make their own decision of what is included in the definition of their own health state. Sense of coherence (SOC) was measured with the short version of 13 questions (Antonovsky, 1993). The concept of SOC includes three components: the perception of comprehensibility, manageability, and meaningfulness. Possible scores range from 13 to 91. A higher score indicates a stronger sense of coherence. The questionnaire has been tested for validity and reliability in Sweden by Langius et al. (Langius et al., 1992). In the present study internal consistency, measured with Cronbach’s a coefficient, was 0.71. Perceived social support was measured with an abbreviated Swedish version of the Interview Schedule for Social Interaction (Undén and Orth-Gomer, 1989, Henderson et al., 1980). Six items measure availability of social integration (AVSI), indicating how many people who are available for social support, and seven items measure availability of attachment (AVAT), indicating occurrence of emotional contacts. The AVSI total score ranges from 6 to 36, and the AVAT total score ranges from 1 to 7, the higher the scores, the higher numbers of existing contacts in the social network. Both AVSI and AVAT showed a high internal consistency, with Cronbach’s a coefficient, of 0.90 and 0.78, respectively, in the present study. The Comprehensive Psychopathological Rating ScaleSelf Affective (CPRS-S-A) was used to measure the psychological health during the past 3 days. Possible scores range from 0 to 60. A high score indicates a deteriorated psychological health, and a score higher than 10 points indicates a clinical significant risk for depression (personal communication). If the spouses had a score above 10 points, the researchers contacted them by telephone and offered guidance of how to get help. This scale has been tested for validity and reliability in a Swedish study (Svanborg and Åsberg, 1994). In the present study internal consistency, measured with Cronbach’s a coefficient, was 0.90. 2.3. Ethical consideration The Local Ethics Committee of the Karolinska Hospital approved the study, Dn:01-142. All data were handled anonymously. The participants received written and verbal information about the study and gave their informed consent. 2.4. Data analysis w2 test and independent Student’s t-test were performed to compare male and female spouses attending the study, regarding age of spouse and patient, sex distribution, and number of strokes that the patient had suffered. Analysis of variance (ANOVA), with repeated measures, was performed for all main outcome variables, comparing male and female spouses over time (baseline, 6 and 12 months). Interaction effect has been studied between within-subjects factor (i.e., baseline, after 6 and 12 months) and between-subjects factor (i.e., male or female spouse). The analyses were adjusted for age. Student’s independent t-test and Mann–Whitney U-test, when applicable, were conducted to crosssectionally compare male and female spouses regarding the baseline, 6 and 12 months assessments. Since a few participants did not fill out all of the questionnaires, the analyses were restricted only to those from whom data was available for all assessments, i.e., ‘‘per protocol’’ analyses. In this study probability values of o0.05 were considered as statistically significant. The statistical analyses were performed using the SPSS software 12.0 for Windows. ARTICLE IN PRESS J. Larson et al. / International Journal of Nursing Studies 45 (2008) 257–265 3. Results Among the participants, there were significant differences (p ¼ 0.02) in age, between the male (mean age 72.10 year, SD ¼ 11.94) and female spouses (mean age 66.24 year, SD ¼ 9.31), but no other significant differences were found regarding demographic data (Table 1). When comparing the male and female groups crosssectionally at baseline, the analyses showed that the female spouses had a lower general well-being (p ¼ 0.02), energy (p ¼ 0.03), and higher AVAT (p ¼ 0.02) than the male spouses (Table 2). After 6 months the female spouses had statistically significant lower general well-being (po0.01), energy (p ¼ 0.04), positive well-being (p ¼ 0.01), and SOC (p ¼ 0.02) than the male spouses. The female spouses also had a higher negative well-being (p ¼ 0.04), AVAT (po0.01), and CPRS-S-A (p ¼ 0.04) than the male spouses (Table 2). At the 12 month assessment, female spouses continued to have a higher negative well-being (p ¼ 0.02) and AVAT (p ¼ 0.02) than the male spouses (Table 2). The ANOVA (Table 2) showed significant differences between male and female spouses over time, in general well-being (p ¼ 0.03), and positive well-being (p ¼ 0.04), when adjusted for age. No other significant differences were found between the genders. The ANOVA also showed significant differences over time within groups regarding Barthel Index (p ¼ 0.04), and energy (p ¼ 0.04). 4. Discussion 4.1. Findings The main findings in the present study reveal gender differences over time, among spouses of stroke patients in well-being, as well as in the social network. Already at baseline we found gender differences, however, it is of importance to consider that the baseline assessment took place after the patients’ stroke event, i.e., this could be interpreted as an early effect of the stroke event. 261 Our results show that the female spouses are more negatively affected in their caregiver role than the male spouses, resulting in a poor psychological well-being for the women, which is also supported by other studies (Borden and Berlin, 1990; Wyller et al., 2003). It is often difficult to distinguish between informal caregiving and the patterns of personal care within family and gender relations. Many women traditionally perform tasks for their spouses and families that would be classified as ‘‘caring’’ if provided by men in reverse (Twigg and Atkin, 1994). According to Goode’s theory of role strain, women have a limited amount of time, energy, and commitment to dedicate to role responsibilities, trying to balance multiple roles of being a mother, wife, employee, and caregiver, which might result in role strain and burden (Goode, 1960). Both genders increased their perceived general quality of life during the 12 months, although the male spouses consistently had a higher quality of life than the women. This might depend on the fact that male caregivers are more likely to feel needed, useful and appreciated, and they also feel that they have chosen to take on the caregiving role, a role that gives more meaning to their lives (Yee and Schulz, 2000; Matthews et al., 2004). Male caregivers also receive outside help with housekeeping more frequently than female caregivers (Matthews et al., 2004). Furthermore, viewed from a traditional gender perspective, caring is often a new task for elderly men, but not for women; hence, it could be seen as something new added to the mens’ life experience. The caregiving role is generally not expected of men and, due to that, others are more likely to notice and to assist them in this role to a greater degree than they would for women (Ekwall et al., 2004). Our findings revealed that female spouses, already at baseline, have a significantly higher perceived social support when it comes to occurrence of emotional contacts (AVAT) than male spouses. This finding is in agreement with the results in a study of spouses of patients with Alzheimer’s disease, where wives were more likely to report having a confidant than the husbands (Pruchno and Resch, 1989). Many spouses Table 1 Comparison of male and female spouses with w2 and independent t-test (n ¼ 100) Age of spouse (years) Age of patient (years) Number of strokes per patient EducationX12 year given in per cent Male (n ¼ 20) Female (n ¼ 80) Mean (SD) Mean (SD) 72.10 (11.94) 70.90 (11.30) 1.30 (0.66) 15.00% 66.24 (9.31) 70.78 (9.88) 1.29 (0.68) 26.30% p-value 0.02 0.96 0.94 0.29 262 Table 2 ANOVA and cross-sectional independent t-test, male and female spouses.

In general, many networks often give short-term aid and support. However, support for a longer period of time, as needed by the informal caregivers, may not be possible to obtain from the social network (Cohen and Syme, 1985). Most participants in our study were spouses of patients with high scores in the Barthel Index, indicating that the patients suffered minor strokes, i.e., the patients were independent in their ADL ability. However, stroke patients affected of a minor stroke, without remaining functional deficits may still have invisible disabilities, such as mental fatigue, emotionalism, concentration and memory difficulties (Stone, 2005). A demographic difference found in the present study applies that male spouses are statistically significantly older than the female spouses, which can be explained by the fact that women are, on average, several years older than men when they suffer their first stroke, i.e., male spouses are often older than female spouses (Wyller, 1999). The same tendency is also found among male and female spouses of patients with Alzheimer’s disease (Pruchno and Resch, 1989). Nurses must ensure that the informal caregivers are assisted in the transition of care from the structured hospital care to home settings and to provide support, so that the caregivers can adapt to their new role and be comfortable and effective as informal caregivers (Bugge et al., 1999). The leading cause of costly long-term institutionalization of stroke patients is negative health effects, experienced by family caregivers. Nursing interventions are needed to reduce these negative health effects, and to inform the caregivers on how to care for the stroke patient as well as for themselves (Han and Haley, 1999; Bakas and Burgener, 2002). findings are unique for caregivers. Further, the group size of male spouses is only one fourth of the female group size; however studies of this kind of population tend to have similar sex distribution (Bugge et al., 1999; O’Connell and Baker, 2004; Smith et al., 2004). The sample was also self-selected, i.e., approximately 40% of the eligible spouses accepted participation in the study. The participants in this study are live-in spouses of the patient, and most participants were spouses of patients that had suffered mild strokes. This implies that the results cannot be generalized to caregivers in general, i.e., the findings are valid for the sample in this study only. 4.1. Strengths Acknowledgements Some of the strengths in this study are the high participation rate (91% participated in all three assessments made), and that the stroke patients, with regards to their high level of independency in ADL, are representative for the general stroke population in Sweden, living at home with co-residents (HulterÅsberg, 2004). Another strength of the study is that the spouses were followed for one year after the stroke event. This study was funded by Health Care Sciences Postgraduate School. We would also like to thank Hans Pettersson for statistical advices, and Lynn Stevenson for linguistic advices. 4.2. Limitations There are some limitations in this study that should be mentioned. We have no ‘‘non-caregiver control group’’ to compare our results with, which would reveal if our 5. Conclusion and implications Results of this study show that female spouses of stroke patients have a negative impact on their psychological well-being, while the male spouses have a lower occurrence of emotional contacts in their social network. Already at baseline, and consistently over time, the female spouses reported lower quality of life and well-being than the male spouses. This study generates the hypotheses that there are gender differences among spousal caregivers of stroke patients. Today, the homehelp service is often modelled on the female domestic role, and therefore the home help may be of little or no use for female caregivers in traditionally male tasks that they find daunting (Twigg and Atkin, 1994). It is important to take the gender differences under consideration when designing a nursing intervention, focusing on individual support, to meet the different needs and demands of male and female caregivers. This process must start already during the patients’ hospitalization and continue in the community setting. References Ahlsiö, B., Britton, M., Murray, V., Theorell, T., 1984.
