THE LOCKER ROOM AS A DEVELOPMENTAL CONTEXT: PREDICTING PERCEPTIONS OF PROSOCIAL AND AGGRESSIVE BEHAVIOR IN YOUTH HOCKEY PLAYERS Scott Anthony Graupensperger A Thesis Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements for the degree of MASTER OF ARTS May 2016 Committee: Marie S. Tisak, Advisor John Tisak, Co-Chair Eric Dubow © 2016 Scott Graupensperger All Rights Reserved iii ABSTRACT Marie S. Tisak, Advisor While many studies have investigated prosocial and aggressive behavior in youth sport, the specific contexts that correspond with sport participation have rarely been studied. To further the understanding of sport as a developmental context, the current study examined the specific setting of the youth hockey locker room and the perceptions of prosocial and aggressive behaviors within it. Specifically, to gain a deeper understanding of locker room social behaviors, the present research used hierarchical multiple regression to test the hypothesis that age, perceived adult supervision, task cohesion, and social cohesion would predict the perceptions of prosocial and aggressive locker room behavior. The results indicated that both adult supervision and task cohesion significantly predicted perceived prosocial behavior and inversely predicted perceived aggression. The presence of an adult figure in the locker room appears to predict the perception of more positive social behavior. These findings also suggest that athletes who perceive more unity in working towards a shared goal perceive greater prosocial behavior and lesser aggressive behavior. Ultimately, the findings from the current study contain highly useful practical implications for youth sport programs and coaches as they strive to create sport environments that are conducive to building character. iv ACKNOWLEDGMENTS I am sincerely grateful for my many sources of support and encouragement throughout this process.

Of interest is the psychosocial development of young athletes through sport participation. Experts in the area of youth sport psychology, Weinberg and Gould (2003), assert that there is an acute need for research to provide a more complete understanding of when and how social behaviors, such as aggression, are most likely to occur in sport settings. An example of a sport related context, seen in the sport of ice hockey, is the locker room. According to the USA Hockey, Inc. Season Final Registration Report, there were 358,744 active and registered youth hockey players in America during the 2014-2015 season (USA Hockey, Inc., 2015), and despite past research studying youth hockey as a whole, little attention has been given to the context of the locker room and how it may impact a child’s development. Preliminary analysis reveals that youth hockey players spend over four hours a week in a locker room, on average, confirming that this context may have a large impact on young athletes. The following review discusses the importance of context in terms of youth development, the development of morality and its components, and finally, team cohesion and its potential impact on the behavior found inside a youth hockey locker room. Context Bronfenbrenner (1979) was critical of developmental psychology by pointing out that much of the research in the field is overly focused on the child, while researchers know very little about the child’s environments and how certain contexts can affect the course of development. Moreover, Bronfenbrenner posits that development of any kind is context PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 2 dependent. The various ways in which children spend their time exposes them to distinct learning environments and unique opportunities for growth and development (Larson & Verma, 1999; Whiting, 1980). Within different contexts, the situational variables are plentiful; including structured versus non-structured activities, level of adult supervision, and cooperative versus competitive activities. The large number of contextual variables provides many unique opportunities for social interactions in children. Organized youth activity. One specific context for development that has been examined is the organized youth activity setting. Activities in which children are supervised in a structured setting have been found to provide children with beneficial experiences that encourage initiative, identity exploration, and the development of teamwork skills (Hansen, Larson, & Dworkin, 2003). Hansen and colleagues also explain that there is a degree of variation within the context of organized youth activities that can offer distinct patterns of learning experiences, such as service and faith-based activities being reported to provide experiences in prosocial norms, while the context of youth sports has been more related to emotional development experiences. Longitudinal research shows a predictive relationship between participation in organized youth activities and positive outcomes such as reduced problem behavior, adjustment skills, and staying in school (DeMartini, 1983; Eccles & Barber, 1999; Eccles & Templeton, 2002). The developmental benefits found in organized youth activities are far greater than in unorganized comparison activities (Hansen et al., 2003). Because organized youth activities such as sport often involve a common group goal, high levels of cooperation, and are of voluntary nature, Larson and Verma (1999) suggest that it is the ideal context for development, when compared to other non-structured or mandatory activities (i.e., hanging out with friends, academic classes). Children are constantly learning and developing, and although organized PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 3 youth activities may be the most germane context to the current study, it is but one of many that a child will experience. Participating in organized youth sport is highly significant from a developmental standpoint, in that sport provides unique social opportunities and exposes a child to adaptive demands that resemble those found in important life settings (Scanlan, 2002). Sport programs have a unique ability to teach and build transferrable life skills that lead to positive outcomes for youth participants (Turnnidge, Côté, & Hancock, 2014). Experiences found in the context of youth sport, specifically in a team setting, have the potential to help prepare a child for teamwork and other social settings in the future. Furthermore, sport participation can provide developmentally constructive outcomes such as character-building, identity development, confidence, and meaningful peer and adult social connectedness (e.g., Camiré & Trudel, 2010; Fraser-Thomas & Côté, 2009; Shields & Bredemeier, 2008). Moreover, Hansen and colleagues (2003) assert that within the context of youth sport, children learn emotional regulation skills such as the ability to control their temper. Forneris, Camiré and Trudel (2012) suggest that those with a vested interest in youth sport (e.g., parents) hold the expectancy that sport participation be a developmentally constructive activity in which youth learn competencies that will extend beyond the realm of sports. Specifically, Arnold (1994, 2001) suggests that sport participation is laden with moral values such as instilling respect for oneself and opponents, equal opportunity, cooperation, and fairness. Similar research has shown that sport activities promote the development of social responsibility, self-control, and moral reasoning (Coakley, 1983; Matsuba & Walker, 1998). Moreover, there is a large volume of evidence suggesting that participation in extracurricular activities, such as organized youth sport, is associated with less antisocial behavior (e.g., school PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 4 dropout and arrest) during adolescence (e.g., Mahoney, 2000; Rutten, et al., 2007; Vazsonyi, Pickering, Belliston, Hessing, & Junger, 2002). While there is an abundance of empirical support for sport as a developmentally beneficial context, Coakley (2011) warns of the common misperception that sport involvement alone can magically yield positive developmental outcomes due to its “inherently good and pure nature.” The positive impact of sport on youth development, has been largely unquestioned (Coakley, 2011) – suggesting that there is a need for deeper exploration on the developmental impact of youth sport participation. Although not inherent, there has been progress in the past decade to formulate frameworks that ensure developmentally productive outcomes. Positive youth development (PYD). Stemming from several disciplines, PYD is a theoretical perspective that views youth as a valuable resource to be fostered, rather than a problem that requires management (Damon, 2004). Turnnidge and colleagues (2014) assert that an important component of this approach is that it engages youth in activities that build upon existing strengths. Three common goals of a developmentally constructive youth sport program are: (a) providing opportunity for physical activity and health, (b) developing foundational motor skills for recreational or elite sport participation, and (c) facilitating psychosocial development through opportunity to learn life-skills (e.g., discipline, commitment, and teamwork) (Côté & Fraser-Thomas, 2007). In the sport context, PYD has been operationalized as consisting of four developmental outcomes that are referred to as the four C’s: confidence, competence, connectedness and character (Côté, Bruner, Erickson, Strachan & Fraser-Thomas, 2010). When combined, the 4C’s create a holistic athlete development framework (Vierimaa, Erickson, Côté, & Gilbert, 2012) that organized youth activities should aim to provide to ensure that the overall sport experience is PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 5 developmentally constructive (Lerner et al., 2005). This framework proposes that all young people possess the potential for positive, successful, and healthy development (Lerner et al., 2005). Weiss and Wiese-Bjornstal (2009) describe PYD as the development of personal skills that will help children to one day become a successful and functional member of society. Past research suggests that the context of youth sport has the capacity to promote the framework of PYD (Weiss, 2008), which Weiss and Wiese-Bjornstal explain is partially a result of the fact that physical activity programs such as youth sports involve supervision from coaches that organize activities specifically designed for optimal youth outcomes. Petitpas, Cornelius, Van Raalte, & Jones (2005) established a PYD based framework designed to be used for planning youth sport programs to ensure that they appropriately foster development. This framework consists of three conditions that must be met in order for a sport experience to maximize healthy youth development: (a) Must take place in an appropriate context, which involves intrinsically motivating activities, a valued role within the team, voluntary participation, clear goals and rules, and take place within a psychologically safe environment, (b) must involve being surrounded by external assets that include a close relationship with coach or mentor, adult monitoring, and community service opportunities, and (c) must promote the acquisition of internal assets such as goal-setting, problem-solving skills, a sense of purpose and identity, and confidence building in skills that can be applied outside of sport (Petitpas et al., 2005). With these three conditions being satisfied, sport can provide an effective forum for youth to learn about themselves and acquire life-skills that will help them as they transition into adulthood. Ultimately, developmental outcomes in youth sport are contingent upon many factors including the nature of the specific sport (Côté & Fraser-Thomas, 2007), the actions of adults involved (Lauer, Gould, Roman, & Pierce, 2010), and the social relationships PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR that are a result of the sport participation (Fry & Gano-Overway, 2010). Supervision. There exists an important link between environmental factors, such as the amount of adult supervision, and the behavior of athletes. Establishing meaningful relationships with caring adults is a highly important asset in young peoples’ lives in terms of promoting optimal development and low levels of risky behavior (Bower, Johnson, Warren, Tirrell & Lerner, 2015; Li & Julian, 2012). Strong coach-athlete relationships are consistently associated with less antisocial and more prosocial behavior in sport (Rutten, Schuengel, Dirks, Stams, & Biesta, 2011; Rutten et al., 2007). In general, the presence of supportive non-parental adults is associated with favorable youth developmental outcomes (Bowers et al., 2012). Because aggression is more common in contexts that lack adequate adult supervision (e.g., playground; Snyder et al., 2003) it is important that coaches and involved adults maintain supervision. There is also something to be said for sport experiences in which the children involved are less supervised. In a summary of relevant research, Green and Chalip (1998) point out that adult supervision has the potential to ruin the fun and take away from the value of peer socialization in youth sport. There is a large body of literature addressing the developmental benefits of youth-initiated deliberate play that is largely unsupervised by adults (e.g., Côté, Baker, & Abernathy, 2007; Côté & Erickson, 2015). Without an adult present, children are exposed to more diverse social situations in sport (Lester & Russell, 2008), which allows childautonomy in negotiating and solving social circumstances (Jarvis, 2007). In a less structured environment with less adult supervision, children begin to develop responsibility for the nature of their own social participation (Côté & Erickson, 2015), which has a positive impact on developing interpersonal social skills that are critical for continued sport participation (Bruner, Eys, & Turnnidge, 2013) as well as the ability to work with and establish productive 6 PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 7 relationships with teammates at the higher levels of sport (Gould, Dieffenbach, & Moffett, 2002). While adult supervision may improve behavior of young athletes, there are also developmentally constructive properties to less supervised situations. Moral Development Sport can be an effective platform to instill transferrable life skills such as strong moral character (e.g., Fraser-Thomas, Côté, & Deakin, 2005; Turnnidge, Côté, & Hancock, 2014). Although researchers acknowledge that character is a broad term, in the current study, character will be investigated specifically in terms of locker room social behaviors between teammates. As Kohlberg (1969) describes, morality is the systematic thoughts and emotions regarding right and wrong in social relationships, which begin forming during childhood and gradually develop into adulthood. Bolter and Weiss (2012) purport that the terms ‘character’ and ‘moral development’ are often used interchangeably in the context of sport, where character refers specifically to perspective-taking and moral reasoning embodied by the engagement of prosocial behaviors and the avoidance of antisocial behaviors (Bredemeier & Shields, 2008; Vieremaa, et al., 2012), while Weiss, Smith, and Stuntz (2008) identify moral development as an umbrella term used in reference to sportspersonship, prosocial behavior, and fair play. Although explicit conceptualizations of right and wrong are different for each individual based on their varying understandings of rights, justice, fairness, and the welfare of people (Turiel, 1983; 2006), sport can be valuable domain to instill broad character values. Throughout the last century, the concept of morality has taken on various theories and emphasis. The cognitive-developmental emphasis of morality suggests that the development of morality takes place through a process of sequential stages (Gibbs, 2003; Kohlberg, 1969; Piaget, 1932/1965) or domains (Turiel 1966, 1983). The moral identity theory (Damon, 1978), on the PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 8 other hand, emphasizes the development of morality as a product of an overall self-identity, which leads the individual to feel a sense of moral responsibility. The moral domains of social development. Turiel (1975, 1978, 1983) divides social development into three distinct domains: moral, societal, and psychological. The moral domain involves issues relating to justice, fairness, rights, and welfare, including acts of hitting, lying, and stealing. The social domain pertains to systems of social relations, such as groups and social systems, such as whether to address an adult by his/her first name of last name. Lastly, the psychological domain refers to aspects such as personality, self, and identity, such as personal choice (Nucci, 1981). The most notable difference between Turiel’s domain theory and those of Piaget (1932/1965) and Kohlberg (1969, 1971) is that Turiel considers the moral and social domain to be separate entities, while Piaget and Kohlberg consider morality and social conventions to be the same conceptual domain (Turiel, 1983). Morality is distinguished as its own domain by adhering to the criteria of generalizability, obligation, inalterability, and independence from authority and rules (Smetana, 2006). The generalizability criterion refers to the judgment of moral transgressions, such as hitting, to be wrong, regardless of the social context (e.g., sport or school). Children judge that peers are obligated to follow moral rules and that such rules are not alterable (cannot change or be eliminated). This rigidity of moral rules poses an issue in sport as athletes commonly experience bracketed morality in which competition and sport are perceived as isolated from conventional contexts in that ethics and moral codes do not apply (Bredemeier & Shields, 1986). Lastly, moral transgressions are considered wrong even in the absence of specific prohibitory rules (e.g., an authority eliminates the rule or does not have a certain rule, such as prohibiting stealing). Components of morality. The context of team sport is a favorable domain for studying PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 9 social behaviors as they relate to peer groups (Holt, Black, Tamminen, Fox, & Mandigo, 2008). Generally speaking, the term ‘morality’ is made up of two separate dimensions (Tisak, Tisak & Goldstein, 2006). The first is the positive component, which entails behavior that is intended to benefit another (e.g., sharing), and is commonly referred to as prosocial behavior (reviewed in Carlo, 2006). The other is the negative component of morality, which is behavior that involves a negative consequence to another or that violates their rights and welfare, such as aggression (reviewed in Tisak, et al., 2006). Although ‘character’ can be a very broad term, character outcomes in sport are typically investigated in terms of two moral dimensions: prosocial behavior and antisocial behavior (Kavussanu, Seal, & Phillips, 2006; Sage, Kavussanu, & Duda, 2006), however, the current study will specifically investigate aggression rather than all antisocial behaviors. Prosocial behavior. In sport psychology literature, prosocial behavior is commonly defined as voluntary behavior with the intent of benefitting another (Eisenberg & Fabes, 1998), such as encouraging a teammate. This definition, despite focusing on behavior during gameplay, has been widely accepted in sport psychology. Nonetheless, the many different aspects of prosocial behavior have caused ambiguity in establishing a concrete definition among researchers within developmental psychology (Tisak & Ford, 1986). For example, prosocial behavior has been defined as the concern for another’s well-being (Cialdini, Kenrick, & Bauman, 1982), while other researchers maintain that prosocial behavior cannot be defined by using unobservable and abstract motivations (Eisenberg & Mussen, 1989; Gelfand & Hartmann, 1980). Additionally, the behaviors considered to be prosocial have varied among researchers. Many have limited the definition to helping and sharing behaviors, while others have added altruistic and comforting behaviors (Eisenberg & Fabes, 1998; Galliger, Tisak, & Tisak, 2009; Jackson & PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 10 Tisak, 2001). The definition for the current study is grounded in the framework of Tisak, Holub, & Tisak (2007), which coded prosocial behavior into 5 categories: sharing, helping, compliance, social activity, and self-directed activity. To avoid limiting the definition of prosocial behavior in ways that past research has, the current study, in line with Tisak and Ford (1986), defines prosocial behavior as any action that is perceived to benefit others, or prompt harmonious relations with others (Hay, 1994). Specifically, prosocial behavior is a form of positive peer interaction that is key to a child’s healthy development because it can encourage feelings of acceptance, support, belonging, and caring (Carlo 2006; Sebanc, 2003). Additional longitudinal self-report research findings suggest that prosocial behaviors are related to better adjustment for adolescents (Wentzel, Barry, & Caldwell, 2004). Regarding the developmental changes occurring in the rate and frequency with which a child behaves prosocially, the existing literature has been far from univocal as prior research has shown that prosocial behavior can increase, decrease, or remain unchanged depending on the age of the participants and the specific type of prosocial behavior being measured (Jackson & Tisak, 2001). Some sources of literature suggest that the rate of prosocial behavior increases with age (Eisenberg & Mussen 1989; Galliger et al., 2009; Romano, Tremblay, Boulerice, & Swisher, 2005), as children become gradually more reliant on their peers (Greener & Crick, 1999). However, a similar study examining mother-child and teacher-child reports found that the level of prosocial behavior gradually decreases along the developmental trajectory (Nantel-Vivier, et al., 2009), finally plateauing during early adolescence, despite increasing levels of empathy and PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 11 moral reasoning during this age period. As it currently stands, there is need to further investigate how the rate and frequency of prosocial behavior changes with age. Aggressive behavior. The negative component of morality concerns the welfare of an individual and violations of rights (Tisak & Ford, 1986), which includes matters of aggressive moral infractions (Caprara et al., 2014). Throughout the years, many debates have taken place over the various definitions of aggression and the many different forms it may take (Coie & Dodge, 1998; Parke & Slaby, 1983). For purposes of the current study, aggression can be understood in a three-part definition. The first part to defining aggression is “any form of behavior that is intended to injure someone physically or psychologically,” (Berkowitz, 1993, p. 3). An alternate understanding of this, and part two of the current definition of aggression, is “behavior that is aimed at harming or injuring another person or persons” (Parke & Slaby, 1983 p. 550). The third and final aspect of defining aggression is “an act that injures or irritates another person” (Eron, 1987, p. 435). Although these three parts are quite similar, and possibly redundant, they coalesce to create a specific yet encompassing understanding of an oftenambiguous term. The three-part definition of the current study is broad enough to include many different acts of aggression, even those that are not traditionally associated as an aggressive act. Aggression has been differentiated into two forms. The first type of aggressive behavior is overt aggression, which is physical acts of aggression or verbal threats (e.g., punching, threatening to hit), while the second type is relational aggression in which the offender attempts to cause harm to the victim by damaging their reputation or friendships (e.g., rumor spreading) (Crick & Bigbee, 1998). Vaillancourt and Hymel (2006) classify physical and verbal aggression into an “overt/direct” category and relational aggression into a “covert/indirect” category. Different PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 12 forms of aggression such as property loss or damage, direct physical violations, verbal attacks, and relationally destructive behavior are all accounted for in the working definition of aggression (Tisak et al., 2006). Peers and moral development. There is a large body of literature suggesting that having strong peer relationships (e.g., with teammates) can help a child develop moral sensitivity (i.e., the ability to identify an ethical problem and to understand the ethical consequences of a decision), increased moral reasoning, and prosocial actions and mannerisms (Bandura, 1986; Damon, 1988). Peer relationships largely influence and shape the developmental benefits of youth sport participation (Evans, Adler, MacDonald, & Côté, 2015; Smith, 2003). Weiss and Stuntz (2004) suggest that moral development is likely to occur through peer interactions that are found in youth sport, such as cooperation and conflict. The bulk of the research in this area has focused on the perceived social approval of aggressive acts of peers, and one’s own attitudes and behaviors in sports (Weiss & Smith, 2002). Solomon (2004) indicates that the level of moral reasoning (i.e., ability to decipher between right and wrong) is negatively correlated to the level of aggression in sports. In other words, youth athletes with higher moral reasoning are likely to exhibit lower levels of aggression. An important finding of research in this domain is that youth athletes perceive their peers (i.e., teammates) as being more approving of violence and aggression than themselves (Mugno & Feltz, 1985; Smith, 1974, 1978; Stuart & Ebbeck, 1995) which is important because team norms and attitudes have a high level of influence on a child’s likelihood of behaving aggressively in sport (Stephens, 2000, 2001). Such findings suggest that youth sport is a fertile context to study the development of aggression, antisocial behaviors, and prosocial behaviors. PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 13 Cohesion The team setting in youth sports has a significant influence on the development of individual behavior (Bruner, et al., 2013; Holt et al., 2008). An important concept in regards to inter-team social behavior is the level of perceived cohesion, which is defined as “a dynamic process which is reflected in the tendency for a group to stick together and remain united in the pursuit of instrumental objectives and/or for the satisfaction of member affective needs” (Carron, Brawley, & Widmeyer, 1998, p. 213). While sport cohesion research has largely focused on adult populations, a series of focus groups and open-ended questionnaires with youth athletes from many different sport disciplines allowed researchers to examine the perceptions of cohesion in younger athletes (Eys, Loughead, Bray, & Carron, 2009a). This age-appropriate cohesion instrument was empirically supported (Eys, Loughead, Bray, & Carron, 2009b) and interpreted to suggest that the perception of cohesion in younger athletes is based on task and social orientations (Eys et al., 2009a). Task orientation is when an athlete is primarily concerned with the unity surrounding the achievement of team objectives, while a social orientation is when an athlete is primarily concerned with developing and maintaining social relationships and activities within the group. Because of this distinction, cohesion is measured in terms of two distinct dimensions: task cohesion (i.e., the level of unity a group possesses towards a common goal) and social cohesion (i.e., the level of unity in regards to social aspects) (Bruner, Eys, Wilson, Côté, 2014). The simplified conceptual model of cohesion in younger athletes, by Eys and colleagues (2009a), falls in line with past research suggesting that youth have a more simplified view of peer experiences (Rubin, Wojslawowicz, Rose-Krasnor, Booth-LaForce, & Burgess, 2006). Furthermore, Martin, Carron, Eys, and Loughead (2012) developed an expanded conceptual PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 14 framework for cohesion in an even younger athlete population. This expansion supports that young athletes are able to understand the concept of cohesion in regards to sports teams (Martin, Carron, Eys, & Loughead, 2011). Relevant literature supports the relationship between perceived team cohesion levels and intra-team social behaviors. Recently, in a study that examined cohesion as a mediating factor between social identity and prosocial/antisocial behavior, Bruner, Boardley, and Côté (2014) found a significant positive correlation between both task and social cohesion and prosocial behavior between teammates. Moreover, Bruner and colleagues found a significant negative relationship between task cohesion and antisocial behavior. Further empirical support of this relationship comes from Taylor and Bruner’s (2012) study on youth soccer players that found higher perceptions of cohesion to be positively associated with emotional regulation and negatively associated with antisocial behavior (e.g., social exclusion). Despite these past correlational findings, a predictive relationship between cohesion and social behavior has yet to be supported empirically. Cohesion is an important concept to study because such affiliation with group members is a very commonly reported motive for youth to participate in organized sports (e.g., Russell, 2014; Weiss & Petlichkoff, 1989). Carron and Eys (2012) established a framework that categorizes the correlates of cohesion into four distinct dimensions: environmental factors, personal factors, leadership factors, and team factors. Environmental factors are those which are related to the specific setting in which the group interactions take place. When a group interacts in close proximity (i.e., physically close to each other), they have a greater tendency to bond and have more opportunity for communication (Eys, Burke, Dennis, & Evans, 2015). Some situations in sport involve greater physical PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 15 proximity among group members such as having a team locker room, rooming together for away games, and taking the same classes in school (Eys et al., 2015). Another environmental factor that is associated with cohesion is team size, where task cohesion decreases as the size of the team increases – a negative relationship that has been attributed to the fact that in larger groups, it is more difficult to reach a group consensus (Carron, Eys, Burke, Jowett, & Lavallee, 2007; Carron, Hausenblaus, & Eys, 2005; Widmeyer, Brawley, & Carron, 1990). Furthermore, Widmeyer and colleagues found an inverted-U relationship between social cohesion and team size in a three-on-three basketball league, where medium sized teams of six showed significantly greater cohesiveness than smaller teams of three or larger teams of nine. Personal factors, such as characteristics and behaviors of team members, are also associated with cohesion. Satisfaction is an important personal factor that is associated with both task and social cohesion (Eys et al., 2015). Reimer and Chelladurai (1998) found that satisfaction in sport teams can come from many sources such as the opportunity to feel competent and valued, as well as feeling socially related to the other members of the team. Widmeyer and Williams (1991) summarize the relationship between cohesion and satisfaction by stating that athletes who are highly satisfied are more likely to positively influence the team dynamic, and that athletes who experience high levels of cohesion are more likely to be satisfied. Another personal factor that is a correlate of cohesion is the amount of social loafing (i.e., the tendency for team members to exert less effort for group task) that takes place within the team (Eys et al., 2015). While athletes in team settings may exert less effort because they believe they will not be individually identified, McKnight, Williams, and Widmeyer (1991) found that members of a swimming relay team showed a negative correlation between task cohesiveness and social loafing (i.e., as task cohesion level increased, social loafing decreased). PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 16 Leadership factors are another important correlate to cohesion, specifically the behavior of the coach. In a study on the techniques used by coaches to build cohesion in golf teams, Widmeyer and Williams (1991) found that the coaches do not play a significant part in the team developing group cohesion, but they did find that the coach’s decision style could influence the level of cohesion. When coaches allow their players to have a part in decisions regarding the team, the players will perceive the team to have more cohesion, when compared to a team that had a coach who made all the decisions (Westre & Weiss, 1991). Transformational leadership, which is a coaching style in which the leaders of a team and the participants engage in a mutual and ongoing process of building each other up to higher levels of motivation, moral reasoning, and self-consciousness (Bass & Riggio, 2006), has been found to be positively associated with the perception of team cohesion (Price & Weiss, 2013). Finally, team factors are correlated to level of perceived cohesion in athletes. Roles, which are sets of behaviors that are expected from teammates who are in a specific position of the group, are a team factor that is associated with cohesiveness. Cohesion is higher when teammates are more accepting of their roles (Benson, Eys, Surya, Dawson, & Schneider, 2013), whatever that role may be. Additionally, Gammage, Carron, & Estabrooks (2001) found that the presence of team norms (i.e., a standard for behavior that is expected of team members) is associated with having higher cohesiveness. Norms reflect the team consensus about behaviors that are considered acceptable (Eys et al., 2015), and have been divided into four athlete-specific contexts: competition, practice, off-season, and social (Munroe, Estabrooks, Dennis, & Carron, 1999). There is a circular relationship between the presence of norms and cohesion in which the development of norms leads to the development of cohesiveness, and as the team develops cohesiveness they also develop greater conformity to team norms (Eys et al., 2015). PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 17 Cohesion is most often studied in regards to its effect on team performance, and with an adult population, leaving much room for research in the areas of youth sport, specifically regarding how the level of perceived cohesion may influence social behaviors. Past research has found that level of cohesion is positively correlated to team success (e.g., Carron, Bray, Eys, 2002; Dobersek, Gershgoren, Becker, & Tenenbaum, 2014; Fuster-Parra, Garcia-Mas, Ponseti, & Leo, 2015), collective-efficacy (Filho, Tenenbaum, & Yang, 2015; Spink, 1990), and positive attitudes towards exercise (Estabrooks & Carron, 1999). Additionally, there is evidence that cohesion is positively related to satisfaction from sport participation in interactive team sports (Spink, Nickel, Wilson, & Odnokon, 2005), individual team sports (e.g., swimming, crosscountry skiing) (Evans & Eys, 2015), and youth exercise groups (Bruner & Spink, 2011), while it is negatively correlated to anxiety levels (Eys, Hardy, Carron, & Beauchamp, 2003) and depression levels (Terry et al., 2000). Another positive behavioral outcome associated with a high level of cohesion is significantly increased effort, which was found in a study of high school basketball players (Bray & Whaley, 2001). The advancement and development of measures of youth sport cohesion (e.g., Eys et al., 2009a; 2009b; Martin et al., 2012) have allowed for research to reveal that cohesion is significantly related to many of the goals of PYD (Bruner et al., 2014). Taylor and Bruner (2012) studied the impact of cohesion on personal development in elite level youth athletes (soccer), and found that a high level of task cohesion is associated with satisfaction of psychological needs, which is in turn associated with aspects of positive youth development (i.e., leadership opportunities, emotional regulation, goal setting, and decreased social exclusion). This finding was later supported in a study involving a wide variety of youth sports, reporting that at the individual level, perceptions of both task and social cohesion are in association with higher PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 18 levels of positive youth development (Bruner et al., 2014). Such findings suggest that perceived cohesion may have a bi-directional relationship with personal development of a young athlete. The development of cohesion with age. From a purely developmental standpoint, perceptions of team cohesion remain largely understudied. For example, while Gruber and Gray (1981) measured cohesion levels across different skill levels of basketball teams, they inadvertently grouped skill level based upon age, finding that elementary school and junior high school teams had higher levels of cohesion than did high school teams. These results were later supported by Granito and Rainey (1988) in a study that found that cohesion levels were greater in high school football teams than in college football teams. Although neither of these studies were designed with the intent of studying developmental differences in levels of cohesion, the findings are in line with Carron and colleagues’ (2005) suggestion that athletes at lower levels have greater cohesion because they can more easily reach consensus regarding task and social unity. Despite theoretical ambivalence on this relationship between cohesion and age, there is enough evidence to suggest that this link is worthy of investigation. PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 19 CURRENT STUDY Bandura (1973) stated that the best way to understand behavior is by taking a closer look at the context in which the behavior occurs, rather than the individual that is exhibiting the behavior – suggesting the importance of context when researching the development of social behaviors (e.g., prosocial and aggressive). As seen in the bioecological model, environmental forces of specific contexts share a joint influence with a child’s biology to mold development (Bronfenbrenner, 2005; Bronfenbrenner & Morris, 2006). Despite the contributions of past research suggesting the importance of a child’s environment, many contexts remain understudied. Previous research involving sport participation has heavily focused on the context of sport gameplay, and rarely addressed the surrounding contexts that go along with sport. Because the context of youth sport is considered to be a positive means of teaching children social behavior, the associated situations and contexts warrant an in depth look; therefore, the current study seeks to gain a further understanding of the youth hockey locker room as a context for social development. According to Bronfenbrenner’s (1979) theory of ecological systems, the sports team and locker room fall within the child’s most immediate level of environment known as the microsystem, making this an important developmental context. Sullivan’s (1953) developmental model of interpersonal relationships suggests that team sports may be beneficial during middle childhood (i.e., ages 7-9 years) as peer group acceptance becomes increasingly important, and children begin to need a sense of belonging. Sport involvement during early adolescence (i.e., ages 10-14 year) allows for teammates to experience close relationships with peers of the same sex, which Sullivan refers to as “chumships”, that can meet interpersonal intimacy needs, buffer against loneliness, facilitate social adjustment, and provide feelings of security, psychological well-being, and self-worth. PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 20 As opposed to relationships with adults, Piaget‘s (1932/1965) theory of cognitive development explains that peer relationships are balanced and equal, which provides cognitive, social, moral, and emotional growth through the opportunity to disagree, negotiate, and resolve conflicts with peers. Hartup (2005) reviewed the ways in which children learn from other children, summarizing the dynamics of peer influence by stating that behavior change in youth can be understood as a function of children’s interactions with one another. Moreover, Piaget believed that the experiences between peers that stem from conflict, such as problem solving, are essential to the development of social perspective-taking as well as moral development. In other words, experiences between peers such as conflict, discussion, and cooperation are likely to increase prosocial behaviors and help to develop moral reasoning. Brustad (1992) recommends that youth sport research utilize the framework of cognitive-developmental theory because the cognitive-developmental characteristics will ultimately affect children’s evaluation of information coming from socialization agents (e.g., teammates). A tightknit area of peer interaction, such as the locker room, may have an important impact on a child’s development, which can be understood through the social cognitive theory. Bandura (1986) claims that starting at a young age, a child’s peers can serve as behavior change agents through the processes of modeling, reinforcement, and punishment, in which children use each other to learn social behaviors. Teammates serve as a source of information as to what behaviors are socially accepted and those that are not, through behavioral norms. From this perspective, a child may experience vicarious reinforcements such as witnessing a fellow player be rewarded in some way for an aggressive act. Children who believe that teammates are more approving of aggressive behavior have a higher likelihood of endorsing aggressive actions in sports (Weiss & Smith, 2002). Social behaviors are observationally learned and reinforced, PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 21 which is important to consider when children participate in team sports. Children often exhibit multiple forms of peer interactions (e.g., prosocial, aggressive) that can contribute to their own as well as their peer’s development (Ladd, Kochenderfer, & Coleman, 1997; Parker & Asher, 1987). Therefore, it is important that systematic research on the youth hockey locker room examine both aggressive and prosocial behavior. Focusing only on aggression in the sport of hockey, as past studies have done (e.g., Gee, Leith, & Sullivan, 2015; Loughead & Leith, 2001; Pappas, McKenry, & Catlett, 2004), may limit the research, and neglect the developmentally constructive properties of youth ice hockey. The current study explored social behaviors amongst teammates in the youth hockey locker room, and identified predictors of both types of behavior that can ultimately be used by youth sport organizations to guide policies and enhance youth hockey players’ experiences. Lastly, drawing form the social identity perspective, behaviors of individuals that are a member of a group for a period of time become more normative, and loyalty to the group increases in a process known as depersonalization (Turner, Hogg, Oakes, Reicher, & Wetherell, 1987). Over time, members begin acting in ways that are consistent with the team’s social norms, which assimilates them into the group, leading to an increase of social acceptance by other group members (Krane & Kaus, 2014). This is important to the current study in that individual members may adopt the social behaviors of the team, whether aggressive or prosocial. PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 22 GOALS AND HYPOTHESES 1.) In the locker room, do youth athletes perceive more prosocial or aggressive behavior? The locker room is stereotypically viewed as a symbolic shrine that is the center of team bonding (Curry, 1991). Despite the apparent significance of the locker room, this context has yet to be investigated in terms of character development for youth athletes. The current study sought to initially reveal whether social behaviors in the locker room are perceived to be predominantly prosocial (e.g., sharing, encouraging) or aggressive (e.g., hitting, name calling). To better understand the perceptions of social behavior in the locker room, the participants are first asked to rate their own behavior towards peers, and then asked about their peers behaviors towards themselves. Because youth tend to overestimate their own level of prosociality (e.g., Holub, 2005), we assessed the total amount of prosocial and aggressive behavior perceptions (i.e., created a composite by combining ‘participant to peer’ and ‘peer to participant’ behavior perceptions) as well as just the perceptions of teammates social behaviors (i.e., peer to participant) as these two calculations may differ. Ultimately, to understand whether youth athletes perceive the locker room to be an environment that has more frequent prosocial or aggressive behavior, it is important to assess the perception of their own behavior as well as their teammate’s behaviors. Based on the realistic conflict theory, it is believed that the superordinate goals of teammates in the locker room setting will promote primarily prosocial behavior (Sherif, 1966) similar to the historic Robber’s Cave study of group dynamics (Sherif, Harvey, White, Hood, & Sherif, 1961). This study also addressed whether children perceive themselves as more prosocial to peers, or peers as more prosocial toward them, within the specific context of the youth hockey locker room. Similarly, the current study addressed whether youth hockey players perceive PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 23 themselves as more aggressive to peers, or peers more aggressive towards them. Past research findings have led to the prediction that young athletes will perceive themselves as more prosocial than their peers, and their peers as more aggressive than themselves (Galliger et al., 2009; Tisak, Tisak, & Laurene, 2012). 2.) Description of Bivariate Correlations An important aspect of the current study was investigating the presence of meaningful statistical relationships between the main variables. Although merely finding a significant bivariate correlation provides little deeper understanding of behavior, it is a worthwhile step in terms of exploration. From a developmental psychology standpoint, it is useful to investigate variables that correlate with age; therefore an important goal of the current study was exploring whether age was significantly related to prosocial and aggressive behavior, task and social cohesion, and adult supervision. Moreover, the current study also sought to investigate the presence of meaningful relationships between each of the aforementioned variables. As a control, all variables were also investigated in terms of their potential correlation to length of tenure with the athletes’ current team. 3.) Predictors of perceived prosocial and aggressive locker room behavior The primary purpose of this study was to investigate variables that predict locker room social behaviors. Despite past evidence showing that aggressive behavior decreases with age, and prosocial behavior increases with age (Brame, Nagin, & Tremblay, 2001; Romano et al., 2005; Tisak & Tisak, 1996), the locker room is a unique social atmosphere that may not be comparable to the contexts of such past studies. It is vital to note that the rules of ice hockey change for older children in that more instrumental aggression (e.g., body-checking) is allowed. Fraser-Thomas, Jeffery-Tosoni, and Baker (2014) completed a qualitative study on aggression in ice hockey, PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 24 finding that there develops a complex power dynamic through being able to legally body-check an opponent, which they claim serves as a backdrop for other aggressive behaviors such as bullying. Similarly, Emery, McKay, Campbell, and Peters (2009) found that aggression increases in older age groups of youth hockey players, and concluded that body-checking influences attitudes of aggression. Because of these past findings, age was controlled for in the first step of the prediction analyses. It was expected that adult supervision level would be positively associated with prosocial behavior and negatively associated with aggressive behavior. Therefore, adult supervision was also investigated as a potential predictor of prosocial and aggressive behavior. It was also expected that there would exist an inverse relationship between age and adult supervision level in that younger age predicts higher levels of adult supervision, while older age predicts lower levels of adult supervision. As such, it was important to use a statistical analysis that would control for collinearity between the variables (i.e., hierarchical multiple regression). Based on the work of Bruner et al. (2014) and Taylor and Bruner (2012), it was expected that there would exist a positive relationship between both types of team cohesion and prosocial teammate behavior, as well as an inverse relationship between cohesion and aggressive behavior. This hypothesis is in line with Johnson and Johnson’s (1989) social interdependence theory which posits that team members who work together on group-level tasks make personal investments in developing fluid working relations and subsequently engage in more mutual helping behaviors. This theory also contends that when team members share a collective task they have greater interpersonal liking for fellow members and create a more harmonious environment. Past research has extended social interdependence theory to children as well (e.g., Bertucci, Johnson, Johnson, & Conte, 2011). Because of strong theoretical justification and PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 25 findings from similar past research, task cohesion and social cohesion were included as potential predictors of prosocial and aggressive behavior perceptions. Based on the limited available research (i.e., Granito & Rainey, 1988; Gruber & Gray, 1981), it was expected that age would be negatively correlated with both types of team cohesion. That is, it was predicted that younger athletes would have higher perceptions of task and social cohesion. Because it was hypothesized that both types of cohesion would be strongly related to one another, it was important to control for other variables. To the author’s knowledge, there is not yet a theory that could explain a relationship between age and cohesion. While it is known that children’s conceptualization of cohesion becomes more complex with age (Eys et al., 2009a), there is no theoretical justification to hypothesize any specific relationship between cohesion levels and age. PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 26 METHOD Data for this study were collected from 251 male youth hockey players who attended the Pro Ambitions Summer Hockey camp, at locations across North America. Upon signing their child up for the summer hockey camp, parents were emailed the opportunity to have their child participate in this study. The age of campers ranged from 6 – 16 years old, however, because of readability issues, data for the present study only investigated responses from youth hockey players that were at least 8 years old. Data from 20 participants were omitted because they were not eight years old yet. We sent out a recruitment email to the parents of 3,074 youth hockey players, of which 487 opened the survey. Of the initial 487 participants who opened the questionnaire, 216 decided not to participate, or did not make it past the demographic questions. In total, 251 participants fit the age requirement and submitted a completed questionnaire with enough data to be analyzed. Of the 251 participants that are included in analyses, 86.6% were Caucasian, and 80.5% reported coming from a family with at least one parent who completed a Bachelor’s degree or higher. Although the sample was predominantly Caucasian and was high in socioeconomic status, this causes no external validity concerns as ice hockey is a highly affluent sport, played primarily by Caucasians. Participants had a mean age of 10.98 years old (SD = 1.92), had an average of 6.12 years of experience in hockey (SD = 2.22), and an average of 3.24 years spent with the current team (SD = 2.08). Finally, it was revealed that participants spent an average of 4.04 hours per week in the locker room (SD = 1.98). These data are presented in Table 1. Measures Demographics. To collect the basic demographic information about the child participants, questions were asked of the parental consent giver, as well as of the youth athletes PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 27 themselves. Following the description of the study and the question of parental consent, parents were asked questions regarding the child’s date of birth, parental education levels, and the ethnicity of the child (see Appendix A). Demographic questions asked of the child included age, years of experience playing hockey, most recent level of hockey played, retrospective estimated average hours per week spent in the locker room during the past season, how many years prior to the season of interest had they been a part of team or organization, and finally to list any other sports that they play (see Appendix B). Prosocial and aggressive behavior. To assess the level of perceived prosocial and aggressive behavior, the current study utilized a modified version of a measure developed by Tisak and Tisak (2007), which has been used in prior similar research (e.g., Galliger et al., 2009; Tisak et al., 2012), but never before in a sport-specific population (see Appendix C). The questionnaire assessed children’s views of how often their peers act prosocially and aggressively towards them, as well as how often they act prosocially and aggressive towards peers. When investigating the levels of perceived prosocial and aggressive behavior in the locker room, it is important to assess the behavior of the participant as well as the participants’ perception of teammate behavior. Whereas past research using this scale has differentiated between participant behavior and peer behavior, the current study combines these two questions to create a contextual variable that measures how much prosocial and aggressive behavior takes place in the locker room. By creating a composite measure that analyzed both participants’ perceptions of their own as well as their peers’ social behavior, a more complete understanding of locker room behavior was afforded. To simplify the wording, the term “kind” was used in place of prosocial, and “not kind” in place of aggressive. Participants were asked the following four questions, and PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 28 in line with the original scale developers (i.e., Tisak & Tisak, 2007) responded using a 4-point Likert-type scale of 1 = never, 2 = sometimes, 3 = a lot, 4 = all the time: There are some days that teammates are kind to each other, and some days that they are not kind. 1. In the locker room, how often are you kind or nice to your teammates? 2. In the locker room, how often are your teammates kind or nice to you? 3. In the locker room, how often are you not kind to your teammates? 4. In the locker room, how often are your teammates not kind to you? The means of question one and question two were compared to investigate whether young athletes view themselves or their peers as more prosocial, while the means of question three and question four were compared to investigate whether participants view themselves or their peers as more aggressive. Furthermore, as previously mentioned, questions one and two combine to create a subscale that measures overall prosocial behavior in the locker room context. Similarly, questions three and four combine to formulate a subscale that measures overall aggressive behavior in the locker room context. Adult supervision. To assess the participant’s perceptions of the amount of supervision, a series of simple items were designed. These items are formatted similarly to the measure used for social behavior. The amount of perceived adult supervision was obtained through five 4-point Likert-type scale (i.e., 1 = never, 2 = sometimes, 3 = a lot, 4 = all the time) questions asking: 1. When you are in the locker room before practice, how often is there an adult supervising the team’s behavior? 2. When you are in the locker room before a game, how often is there an adult supervising the team’s behavior? 3. When you are in the locker room after practice, how often is there an adult supervising the team’s behavior? PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 29 4. When you are in the locker room after a game, how often is there an adult supervising the team’s behavior? 5. How often are you and your teammates in the locker room without any adult supervision? Four of the five questions ask about a specific context (i.e., before/after practice and before/after game), while the fifth item is reverse scored. Because this scale assesses the perception of adult supervision in a variety of common locker room situations, the mean score of the five items generates a score of overall locker room supervision perception (see Appendix D). Cohesion. To measure level of perceived cohesion, the current study utilized the Child Sport Cohesion Questionnaire (Martin et al., 2012; see Appendix E). This questionnaire is currently the most valid cohesion measure for youth sport participants. The questionnaire consists of sixteen 5-point Likert-type Scale questions ranging from “1 = strongly disagree” to “5 = strongly agree.” Two items are spurious negatively worded items that are implemented to avoid response agreement tendencies (i.e., circling all 5’s). Of the fourteen items (not including the spurious negative items), seven are designed to measure task cohesion, while the remaining seven measure social cohesion. The task cohesion items assess the level of cohesion working towards a goal (e.g., “In games, we all get along well”). The social cohesion items relate to the level of cohesion as a social unit (e.g., “We stick together outside of our sport”). PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 30 RESULTS Missing data were deemed to be completely at random, which was assessed using Little’s (1988) missing completely at random (MCAR) test. Because the MCAR statistic did not reject the null hypothesis that missing values diverged from randomness, missing values for scalescored variables (i.e., adult supervision, social cohesion, and task cohesion) were replaced using the expectation-maximization algorithm (Dempster, Laird, & Rubin, 1977; Wu, 1983). Missing values for the prosocial and aggressive behavior items were not replaced because sufficient subscale items were not available to create a mean for the participant. This imputation approach is an adequate method of dealing with missing values, where highly correlated subscale items are available for calculating estimates (Osborne, 2013; Schafer & Graham, 2002). Means and standard deviations of all major variables were calculated (Table 1) as well as the inter-correlations (Table 2). Using Cronbach’s alpha to test the reliability of the scales, it was determined that each subscale had a strong internal consistency (i.e., α > .80), well above the widely accepted threshold of .70 (Nunnally & Berstein, 1994). Because the perceived supervision measure was the only instrument that had not been used in past research, it was the main concern during reliability analysis – resulting in a Cronbach’s alpha of .90. Because the prosocial and aggression subscales only had two items each, alphas were not calculated, however, this instrument has been used in past research (e.g., Galliger et al., 2009; Tisak et al., 2012). This composite measure of social behaviors included perceptions of participants own behavior, as well as perceptions of teammate’s behavior. Although these are independent constructs, participant prosocial behavior perceptions correlated strongly with teammate prosocial behavior perceptions (r = .40, p < .01), as did perceptions of participant aggressive PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 31 behavior with perceived teammate aggressive behavior (r = .45, p < .01) – supporting researchers’ decision to create a composite of the two constructs. 1.) In the locker room, do youth athletes perceive more prosocial or aggressive behavior? First, to assess whether young athletes perceive themselves to be more or less prosocial than peers, the means of the two relevant components were compared using a paired samples ttest. This same statistical test was completed to compare the means of the two aggressionspecific dimensions as well, to assess whether youth athletes view teammates as either more or less aggressive than themselves. Descriptive statistics (Table 1) indicate that participants reported perceiving moderately high levels of prosocial behavior for themselves (M = 3.45, SD = 0.59), as well as their teammates (M = 3.05, SD = 0.68), while perceiving low levels of aggressive behavior for themselves (M = 1.31, SD = 0.47) as well as their teammates (M = 1.62, SD = 0.61). When compared to teammates, participants perceived themselves to be significantly more prosocial (t(250) = 9.20, p < .001) and significantly less aggressive (t(246) = -8.35, p < .001). This finding is in line with past research suggesting that children tend to overestimate their own prosocial behavior (Holub, 2005; Tisak et al., 2012) and overestimate peer aggression tendencies (Mugno & Feltz, 1985; Smith, 1974, 1978; Stuart & Ebbeck, 1995). To analyze whether youth hockey players perceived more prosocial behavior or more aggressive behavior in the locker room, the current study compared the means of each social behavior type using a paired samples t-test. Descriptive statistics (Table 1) show that overall, youth hockey players report moderately high levels of perceived prosocial behavior and moderately low levels of perceived aggressive behavior in the locker room. A simple paired samples t-test revealed that total perceived prosocial behavior (M = 3.25, SD = 0.53) was significantly greater than total perceived aggressive behavior (M = 1.46, SD = .46) in the youth PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 32 hockey locker room (t(246) = 32.16, p < .001). Moreover, to account for the possibility that participants overestimated their own perceived prosocial behavior, or underestimated their own perceived aggressive behavior towards teammates, a separate paired samples t-test was run to compare the perception of peer behavior towards the participants, separately. Results indicated that perceived peer prosocial behaviors towards participants (M = 3.05, SD = 0.68) were significantly greater than perceived peer aggressive behaviors toward participants (M = 1.62, SD = 0.61) (t(247) = 19.61, p < .001), showing that skewed estimations did not negate the significant difference between perceived prosocial locker room behaviors and perceived aggressive locker room behaviors. 2.) Description of Bivariate Correlations An inspection of the bivariate correlations between key variables (i.e., Table 2) revealed interesting significant associations. Age was related negatively to perceived prosocial behavior (r = -.14, p < .05), and positively to perceived aggressive behavior (r = .14, p < .05), suggesting that older hockey players perceived less prosocial and more aggressive behavior than younger players. As hypothesized, age was inversely related to task cohesion (r = -.16, p < .05), however, age had no significant relationship with social cohesion. Not surprisingly, age was strongly associated with the amount of perceived supervision in the locker room (r = -.40, p < .01), since older athletes tend to require less adult assistance. As anticipated, social cohesion was strongly related to task cohesion (r = .64, p < .01), but not so strongly as to consider these two constructs to be redundant or in danger of multicollinearity (i.e., r > .9 between predictors; Field, 2013). Social cohesion was positively related to perceived prosocial behavior (r = .37, p < .01) and negatively to perceived aggressive behavior (r = -.15, p < .05), while task cohesion correlated with perceived prosocial behavior (r PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 33 = .46, p < .01) and perceived aggressive behavior (r = -.38, p < .01), indicating that increased cohesion levels were associated with perceptions of more positive, prosocial behaviors, and less aggressive behaviors. Moreover, supervision was significantly related to both social cohesion (r = .18, p < .01) and task cohesion (r = .32, p < .01), indicating that higher supervision levels may be bi-directionally related to a more cohesive team. There was also a strong inverse relationship between perceptions of prosocial behavior and perceptions of aggressive behavior (r = -.55, p < .01). It is also worth noting that athlete’s length of tenure with current team was not associated with either cohesion levels or social behaviors. 3.) Predictors of perceived prosocial and aggressive locker room behavior Hierarchical Multiple Regression Model for Prosocial Behavior The present study investigated variables that predict perceptions of prosocial behavior in the locker room. Hierarchical regression (blockwise entry) was used to predict perceived prosocial behavior based on age, perception of supervision, social cohesion, and task cohesion. When using hierarchical regression, the foundation of the model should be based on theory and relevant past findings (Pedhauzer, 1982), and the hierarchical ordering for entry should rely on causal priority (Cohen, Cohen, West, & Aiken, 2003). Past research shows that age is an important variable when predicting prosocial behavior (Brame et al., 2001; Romano et al., 2005; Tisak & Tisak, 1996), and was therefore entered into the regression model first, followed by supervision, social cohesion, and task cohesion, in the second step. Furthermore, the relationship between age and social behavior cannot be bi-directional, and is subsequently a causal relationship, which Cohen and colleagues (2003) suggest is a basis to include age in step one. A significant regression equation was found for predicting perceptions of prosocial behavior on age independently of other variables in step one (F(1, 249) = 4.60, p <.05). PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 34 Moreover, a significant regression equation was also found for step two, which added three additional predictor variables: perceptions of adult supervision, social cohesion, and task cohesion (F(3, 246) = 24.93, p <.001). Whereas the model with only age as a predictor (i.e., step one) explained 1.8% of the total variance in perceived prosocial behavior, adding supervision, social cohesion, and task cohesion in step two increased the variance explained to 25%. Table 3 reports the results of the multiple regression analysis. While age was a significant predictor of perceived prosocial behavior (β = -.14, p < .05) in step one, controlling for perceived supervision, task cohesion, and social cohesion in step two revealed that age was no longer a significant predictor (β = -.01, p > .05). Adding adult supervision, social cohesion, and task cohesion in step two predicted perceived prosocial behavior above and beyond the effect of age. Task cohesion was found to be the strongest predictor of perceived prosocial behavior (β = .32, p < .001), followed by adult supervision (β = .17, p < .01), while social cohesion was not a significant predictor of perceived prosocial behavior (β = .13, p > .05). It is good practice to always observe the variance inflation factor (VIF) and tolerance collinearity diagnostics. Many authors agree that multicollinearity is only a concern when tolerance is below .2 and/or the VIF is above 10 (e.g., Menard, 2002; Myers, 1990; O’Brien, 2007), which is not the case in the current study as the lowest tolerance level for the model is .548, and the highest VIF value is 1.82 (Mean VIF = 1.50). The Durbin-Watson test statistic, testing the assumption of independent errors, was 1.73. Conservatively, values that fall between 1 and 3 show no cause for concern, and the closer to 2, the better (Field, 2013). Based on this conservative rule, 1.73 is close enough to 2 that the assumption has more than likely been met. PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 35 Hierarchical Multiple Regression Model for Aggressive Behavior The present study also used hierarchical regression to investigate predictors of perceived aggressive behavior in the youth hockey locker room. Consistent with the previous analysis, age was entered in step one, with perceived adult supervision, task cohesion, and social cohesion added in step two. Significant regression equations were found predicting perceptions of aggressive behavior on age (F(1, 245) = 4.91, p <.05) in step one, as well as in step two which predicted perceptions of aggressive behavior on adult supervision, social cohesion, and task cohesion (F(3, 242) = 13.32, p <.001). Age in step one accounted for 2% of the variance in perceived aggressive behavior, while adding the additional predictors to the model in step two accounted for 18% of the total variance. Adding task cohesion, social cohesion, and perceived supervision (i.e., step 2) to the model resulted in a ΔR2 of .16. Table 4 represents the model parameters for predicting perceived aggressive locker room behavior. When age was included individually in step one, it significantly predicted perceived aggressive behavior (β = 0.14, p < .05), but after step two factored in perceived adult supervision, social cohesion, and task cohesion, age was no longer a significant predictor of perceived aggression – indicating that the addition of these three variables predicted perceived aggressive behavior above and beyond the effect of age. Task cohesion was the strongest predictor of perceived aggressive behavior (β = -0.41, p < .001), suggesting that as task cohesion increases, perceptions of aggression decrease. Perceived supervision was also a significant predictor of perceived aggressive behavior (β = -.18, p < .01), indicating that higher levels of perceived supervision is associated with lower levels of perceived aggressive behavior. Lastly, despite being related to perceived aggression in the correlation matrix, social cohesion did not significantly predict perceived aggressive behavior (β = 0.14, p > .05). PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 36 The largest VIF value was 1.84, and the average VIF score was 1.51, which suggests that multicollinearity is of no concern in this model. None of the tolerance levels fall below the 0.2 threshold, therefore there is no cause for concern. The assumption of independent errors was met with a Durbin-Watson test value of 1.77. PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 37 DISCUSSION Based on the current findings, the locker room appears to be a constructive context in which perceptions of behavior are largely prosocial in nature, and perceived aggression is relatively uncommon. This finding supports that the specific sport related context of the locker room is an environment that is constructive to the development of character. Based on the 4C’s model of positive developmental outcomes (Côté & Gilbert, 2009), building character is a primary goal of youth sport participation, which has been measured in previous sport psychology research by calculating the difference between antisocial behavior and prosocial behavior (Erickson & Côté, 2016). In line with Bandura’s (1986) social cognitive theory, the prosocial behaviors found in the locker room may serve as models of reinforcement in which young athletes learn appropriate behavior through peer observation. The primarily prosocial peer interactions in the locker room create a constructive dynamic between children in which behavior is learned from one another (Hartup, 2005). Whereas some contexts, such as the playground, feature more aggressive behavior than prosocial behavior (Snyder et al., 2003), the current study reveals that the perceptions of behavior in the locker room are significantly more prosocial than aggressive, and therefore appears to serve as a context in which young athletes may learn transferrable group social skills. As predicted, the current study revealed that young athletes view peers as less prosocial, and more aggressive than themselves. This finding is consistent with decades of past research, which has consistently found that young athletes perceive peers as being more approving of aggressive behavior than themselves (Mugno & Feltz, 1985; Smith, 1974, 1978; Stuart & Ebbeck, 1995). This finding is also consistent with developmental psychology literature (Galliger et al., 2009; Holub, 2005; Tisak et al., 2012). More specifically, Holub (2005) PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 38 investigated children’s social competency, finding that children commonly overrate their own prosocial ability. It is highly likely that the participants in the current study overrated their own prosocial behavior while underrating their own aggressive behavior. This self-report limitation will be further addressed below. The focus of the current study was to investigate variables that may predict perceptions of prosocial and aggressive behavior in the youth hockey locker room. As anticipated, age initially predicted both prosocial and aggressive behavior before controlling for perceptions of adult supervision, task cohesion, and social cohesion. In the final regression models, it was revealed that perceived adult supervision and task cohesion significantly predicted perceived prosocial and aggressive locker room behavior, while age and social cohesion did not. Pearson’s correlations revealed that age was significantly related to adult supervision as well as task cohesion, which might explain why age was no longer a significant predictor upon adding these variables to the regression models in step 2. Adult supervision was related to perceived prosocial behavior and inversely related to perceived aggressive behavior. These results corroborate existing literature consistently showing that greater adult supervision is positively related to prosocial behavior (e.g., Tisak et al., 2012), and inversely correlated with aggressive behavior (e.g., Snyder et al., 2003). Age is likely inversely related to adult supervision because of factors such as younger ice hockey players needing help with equipment (e.g., tying skates), and older players wanting more autonomy in sport experiences. Perceptions of task cohesion significantly predicted perceived prosocial behavior and perceived aggressive behavior. As predicted, this finding supports the social interdependence theory (Johnson & Johnson, 1989) which claims that team members with a shared task invest in PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 39 developing smooth interpersonal interactions and have greater interpersonal liking and harmony within the group (Bertucci, et al., 2011). Bruner and colleagues (2014) found a similar positive relationship between task cohesion and prosocial behavior of athletes, which was explained through qualitative work from Eys et al., (2009b) suggesting that task cohesion is associated with better teamwork and communication. Bruner et al., (2014) also speculated that stronger intragroup processes, such as greater teamwork, may lead to more prosocial teammate behavior, such as encouragement, and enhanced valuing of teammate contributions that in-turn reduces antisocial teammate behaviors such as aggression. Moreover, task cohesion was inversely related to age – a finding that corroborates existing literature (e.g., Granito & Rainey, 1988; Gruber & Gray, 1981). Carron and colleagues (2005) suggest that less experienced athletes playing at lower levels have greater cohesion as consensus is more easily reached regarding task and social unity, which was supported by the current findings. Furthermore, Carron, Shapcott, and Burke (2007) assert that cohesion decreases as the level of play increases, which may be reflected in the inverse relationship between age and task cohesion. It can also be speculated that as athletes get older there is increased pressure on them to stand out from their teammates, resulting in more selfish play. This, however, is purely speculation, and is a topic that deserves further investigation. Social cohesion was strongly related to prosocial behavior, and inversely related to aggressive behavior. Eys and colleagues (2009b) found that high levels of social cohesion often leads to the formulation of meaningful friendships, which may partially explain why athletes with high perceptions of social cohesion are more prosocial and less aggressive to teammates (Bruner et al., 2014). Another interesting finding is that supervision is strongly related to both social and task cohesion, suggesting that teams who have more frequent adult presence work PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 40 better towards the pursuit of unified goals and are more united in regards to social aspects. This finding adds to Carron and Eys’ (2012) correlates of cohesion framework. Lastly, although no hypotheses were formulated regarding tenure with current team, it was surprising that this was not related to either type of cohesion, or perceptions of either type of social behavior. Practical Implications The timely findings from the current study support Weinberg and Gould’s (2003) call for research that provides youth sport stakeholders necessary information regarding when and how aggression is manifested in the youth sport setting. Specifically, this study effectively investigated predictors of appropriate and inappropriate social behaviors in the youth hockey locker room – a context in which young athletes spend a considerable amount of time – that can be used to inform youth sport program and coaching policies. The practicality of this research is quite timely, given that the locker room is a place where youth sport research should look to better understand pernicious sport issues such as bullying and sport attrition. Given the clear connections between adult supervision and locker room behaviors, it is imperative that youth hockey programs adamantly ensure the presence of adequate adult supervision in the locker room at all times, regardless of the athlete’s age. Doing so appears likely to improve the perceptions of prosocial behavior and reduce the perceptions of aggressive behavior, thus establishing an environment that better promotes character building in young athletes. Often it seems that the coaches are responsible for the supervision of the locker room, which may be problematic as coaches already have many responsibilities that often times make it so that they are not able to be present in the locker room. Before a game or practice, coaches may have responsibilities such as creating the game or practice plans, meeting with opposing coaches, or even scouting the games taking place before their team plays. The same is true following a PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 41 game or practice. It would be beneficial for teams to have parents take turns volunteering as locker room monitors, though this may undermine the perceived sanctity of the locker room in many ways. This is a quandary that may require future research. Given that task cohesion levels predict perceptions of prosocial and aggressive behavior, it may encourage character development if youth sport coaches focus on increasing team cohesion. The benefits of cohesion in sport teams are already well documented in the sport psychology literature (e.g., increased performance, increased sport satisfaction), and it can now be derived that cohesion may also increase the character building qualities of sport participation. Specifically, coaches may take caution against practice plans that involve too much intrateam competition, and instead focus on ways of increasing how the team members work together. By doing so, coaches may contribute to greater levels of perceived prosocial behavior and lesser levels of perceived aggressive behavior in the locker room. Limitations and Future Directions By collecting data via online survey, it made it possible to use a geographically diverse sample, though this procedure did not come without limitations. Reaching youth hockey players required emailing parents or guardians, which created a limitation in that we could not be absolutely certain that parents were not influencing the participant responses. Precautions were taken to the best of our ability, by stressing to the parents the importance of letting their child take the questionnaire in private. It should be noted, however, that parents were allowed to first look over the questionnaire so they knew exactly what their child would be asked. Future research efforts should make certain that parents are not influencing the responses of the child participants. PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 42 It appears that many of the recruited youth hockey players began to take the questionnaire (i.e., answered at least one question) only to terminate immediately - leading to a rather high attrition rate. In line with responsible and ethical research practices, it was made very clear to the youth participants that they could choose to stop the questionnaire at any point. Perhaps many were simply curious to see the questionnaire, and had no real intent of completing it. Future research may consider ways to ensure participants are serious about completing the questionnaire before they begin. Admittedly, participants were all male primarily due to the convenience of recruitment, although females changing in a male dominated locker room may have been overly problematic to the study. While the current study cautiously included only male participants, the reality of the sport of hockey is that both males and females play and often do so on co-ed teams. Because of the complicated nature of males and females dressing together in a locker room, future research may take aim at this dynamic. While ice hockey is already an affluent sport, recruiting participants from a rather expensive summer hockey camp may have created a highly homogenous sample. Apart from the cost involved in the summer hockey camp, it is also plausible that these athletes are much more serious about the sport based on year round training. The current sample may neglect recreationlevel players. Furthermore, participants were volunteers for the study rather than random sample, and more importantly is that parents also volunteered to let their child participate. This may have influenced the sample as parents of highly-aggressive children may not have allowed their children to participate in the study, or even allowed their children to attend the summer hockey camp at all. It may be reasonable to assume that the majority of the participants were wellbehaved children if their parents felt comfortable sending them to an all-day weeklong summer PREDICTORS OF LOCKER ROOM SOCIAL BEHAVIOR 43 hockey camp. Additionally, the retrospective nature of the study is a limitation in that the study took place during the off-season and children may not accurately remember their perceptions from three or four months prior (i.e., hockey seasons typically end in March, data was collected during July and August). Future research would benefit from recruiting participants during the season and directly from the youth sport organizations that the athletes are members of. An additional limitation was the self-report nature of the study, especially regarding prosocial and aggressive behavior. Using observational and peer nomination techniques to assess social behaviors (e.g., Kavussanu, Stamp, Slade, & Ring, 2009; Ridgers, Stratton, & McKenzie, 2010) could extend the findings from the current study. Furthermore, without an element of experimental manipulation, causality cannot be established between any of the relationships. As such, future research should look to experimental design to test whether adult supervision causes more prosocial behavior and/or less aggressive behavior. Similarly, experimental work could seek to investigate group-based cohesion interventions (e.g., teambuilding) to determine whether this variable truly causes increased prosociality and decreased aggression.
