The nature of status: Navigating the varied approaches to conceptualizing and measuring status.

Members of small groups fundamentally desire status as status underpins members' self-concept and dictates behavior in groups. Moreover, group members readily orient and update status perceptions that index the social standing of themselves and other members. Yet, our understanding is obscured by variability in how researchers study status. In the current review, we crystallize knowledge regarding the nature of status by characterizing variability in definitions, measures, and analytic frameworks. We advocate a definition of status that draws together attributes of respect, admiration, and voluntary deference. We also distinguish reputational and relational status operationalizations and address implications pertaining to measurement along with downstream decisions involving data management and analysis. We encourage a deliberate approach to ensure congruency in how status is defined, measured, and analyzed within a research program. This review also guides theory and hypothesis generation regarding how status-related processes may vary based on different forms of status or differing contexts.

Distinctions in group members' status naturally arise during group interactions. High status tends to be associated with an array of benefits, such as receiving more respect and attention, enjoying better psychological and physical health, and having greater access to valued resources and opportunities. As such, people fundamentally desire status, vigilantly attend to their own and others' status, and actively pursue status. Status also powerfully influences group functioning. Whereas a consensually formed status hierarchy may provide order and increase coordination, disputes over status rank can undermine cooperation and encourage conflict among group members. Despite the critical role status plays in social interactions, researchers continue to disagree about how status should be defined and studied. Without a consistent definition and a measurement guideline, it is difficult to produce cumulative knowledge regarding when, for whom, and why status is afforded to others, and the consequences of gaining, losing, or threats to one's status. In this review, we advocate a status definition that identifies respect, admiration, and voluntary deference as three essential attributes of status. We also distinguish status that is consensually conferred by a group (i.e., reputational status) from status conferred by a particular group member (i.e., relational status). We conclude this paper by providing a guide of measurement options and data management strategies that are suitable for studying distinctive research questions.

Modelling Age-Varying Associations among Group Memberships, Neighborhood Connectedness, and Well-Being.

Individuals who maintain group memberships in their community tend to experience improved well-being relative to those who participate in few or no groups. There are, however, few investigations targeting variability in the correlates of group membership across the lifespan. The present examination probed age-related variability in the association between group memberships and subjective connectedness as well as well-being. Participants included 3,940 (mean age = 45.61 years, standard deviation [SD] = 15.62) Canadian and American respondents who completed an online survey during August of 2020 (i.e., amidst the COVID-19 pandemic). Time-varying effects modelling was used to estimate coefficients for group membership at each age within the sample. Memberships in social groups positively predicted connectedness, and this association was strongest in middle-to-older age; a similar association was also evident when predicting well-being. Connectedness was also a positive predictor of well-being throughout most ages. These findings build on emerging research conveying how group memberships have significance for people currently in middle-to-older age.

I AM FAMILY: Understanding the adapted sport experiences of family members of military personnel with physical and psychological illnesses and injuries through the lens of the Invictus Games.

Family are influential actors in adapted sport participation. However, little is known about their experiences with adapted sport. The current study sought to explore the experiences of families in adapted sport through the context of the Invictus Games, an international adapted sport competition for military personnel with physical and psychological illnesses and injuries that is unique in its inclusion of family programming. Family members (n = 21; partners, parents, siblings, and children) of Invictus Games Toronto 2017 competitors participated in semi-structured interviews. Data were analyzed using reflexive thematic analysis. Three themes were identified: recognition of family experiences during service and after onset of disability; creating a sense of belonging; and improving family knowledge and perceptions. This study provides insight regarding how adapted sport events can support the well-being of both individuals with illnesses and injuries and their families.

Developing and evaluating a peer-based mental health literacy intervention with adolescent athletes.

Widespread adolescent involvement in organized sport means that sport contexts are well-suited to 'actively' integrate prevention programs that may promote population-level change. This mixed methods study aimed to evaluate the feasibility and acceptability of a peer-based mental health literacy intervention. The intervention (i.e., Team Talk) was presented to eleven adolescent sport teams in the United States, with a total of 174 participants. Athlete participants completed surveys immediately before and after the intervention-including measures of workshop acceptability, social identity, and help-seeking behaviors. Semi-structured interviews were also conducted with a subset of five athletes, nine parents, and two coaches. With respect to recruitment as an indicator of feasibility, club-level adoption of the intervention was low, with difficulty recruiting clubs for intervention delivery. This signals that feasibility of the intervention-as it is currently designed and implemented by the research team-is low when considering similar competitive adolescent sport clubs and delivered as team-level workshops. Meanwhile, participants reported high acceptability of the intervention, and acceptability levels across participants was predicted by contextual factors related to implementation such as session duration. Regarding limited efficacy testing with measures completed before and after the intervention session: (a) social identity scores increased following the intervention, and (b) significant differences were not identified regarding efficacy to recognize symptoms of mental disorders. Athlete, coach, and parent interview responses also described potential adaptations to mental health programs. This research demonstrates the potential utility of peer-based mental health literacy interventions, while also revealing that further implementation research is necessary to adapt mental health literacy interventions to suit diverse adolescent sport contexts.

Examining non-technical skills for ad hoc resuscitation teams: a scoping review and taxonomy of team-related concepts.

BACKGROUND: Non-technical skills (NTS) concepts from high-risk industries such as aviation have been enthusiastically applied to medical teams for decades. Yet it remains unclear whether-and how-these concepts impact resuscitation team performance. In the context of ad hoc teams in prehospital, emergency department, and trauma domains, even less is known about their relevance and impact. METHODS: This scoping review, guided by PRISMA-ScR and Arksey & O'Malley's framework, included a systematic search across five databases, followed by article selection and extracting and synthesizing data. Articles were eligible for inclusion if they pertained to NTS for resuscitation teams performing in prehospital, emergency department, or trauma settings. Articles were subjected to descriptive analysis, coherence analysis, and citation network analysis. RESULTS: Sixty-one articles were included. Descriptive analysis identified fourteen unique non-technical skills. Coherence analysis revealed inconsistencies in both definition and measurement of various NTS constructs, while citation network analysis suggests parallel, disconnected scholarly conversations that foster discordance in their operationalization across domains. To reconcile these inconsistencies, we offer a taxonomy of non-technical skills for ad hoc resuscitation teams. CONCLUSION: This scoping review presents a vigorous investigation into the literature pertaining to how NTS influence optimal resuscitation performance for ad hoc prehospital, emergency department, and trauma teams. Our proposed taxonomy offers a coherent foundation and shared vocabulary for future research and education efforts. Finally, we identify important limitations regarding the traditional measurement of NTS, which constrain our understanding of how and why these concepts support optimal performance in team resuscitation.

A Season-Long Examination of Team Structure and Its Implications for Subgroups in Individual Sport.

The authors explored how sport structure predisposed a team to subgroup formation and influenced athlete interactions and team functioning. A season-long qualitative case study was undertaken with a nationally ranked Canadian track and field team. Semistructured interviews were conducted with coaches (n = 4) and athletes (n = 11) from different event groups (e.g., sprinters, jumpers) at the beginning and at the end of the season. The results highlighted constraints that directly impacted athlete interactions and predisposed the group to subgroup formation (e.g., sport/event type, facility/schedule limitations, team size/change over time). The constraints led to structural divides that impacted interactions but could be overcome through team building, engaging with leaders, and prioritizing communication. These findings underline how structure imposed by the design of sports impacts teammate interactions and how practitioners, coaches, and athletes can manage groups when facing such constraints. The authors describe theoretical and practical implications while also proposing potential future directions.

A Scoping Review on College Student Physical Activity: How Do Researchers Measure Activity and Examine Inequities?

BACKGROUND: The purpose of this scoping review was to critically examine the design and quality of contemporary research involving college student physical activity participation, focusing on physical activity measurement, assessment of sociodemographic characteristics, and examination of inequities based on sociodemographic characteristics. METHODS: Systematic searches were conducted in 4 electronic databases. RESULTS: From 28,951 sources screened, data were extracted from 488 that met the inclusion criteria. The majority of the studies were cross-sectional in design (91.4%) and employed convenience sampling methods (83.0%). Based on the subsample of studies that reported the percentage of students meeting aerobic (n = 158; equivalent of 150 min/wk of moderate physical activity) and muscle-strengthening activity recommendations (n = 8; ≥2 times/wk), 58.7% and 47.8% of students met aerobic and muscle-strengthening recommendations, respectively. With the exception of age and sex, sociodemographic characteristics were rarely assessed, and inequities based upon them were even more scarcely examined-with no apparent increase in reporting over the past decade. CONCLUSIONS: College student physical activity levels remain concerningly low. The generalizability of findings from the contemporary literature is limited due to study design, and acknowledgement of the influence that sociodemographic characteristics have on physical activity has largely been overlooked. Recommendations for future research directions and practices are provided.

Dynamic characteristics of groups and individuals that amplify adherence to perceived drinking norms in college club sport teams: A longitudinal multilevel investigation.

Social norms positively predict college students' alcohol use, but it is critical to explore heterogeneity in these patterns to identify which students are most susceptible to normative influences. The current study explored the nature of drinking norms within college student peer sport clubs. We examined the association between self-reported alcohol use (i.e., number of drinks in a typical week) and perceived descriptive/injunctive norms as an indicator of norm adherence and then tested moderating effects of social constructs related to the group: Social identification with one's team, along with social network-derived indices of indegree centrality and network density. We sampled members of 35 intact college club sport teams at 3 timepoints across the school year (N = 1,054; 61% female). Multilevel modeling was employed to estimate moderating effects at within-person, between-person, and between-groups levels. Initial analyses revealed that perceived group norms predicted self-reported alcohol use, and that teams approached consensus on the groups' drinking norms over time. Several significant time-varying moderation patterns were uncovered. At timepoints when students identified more strongly with their team (relative to person-mean levels), they more readily adhered to perceived descriptive and injunctive team drinking norms. Students also adhered more closely to these perceived team drinking norms at timepoints when students were nominated as having relatively lower indegree centrality. Cross-level interactions revealed that neither network density nor team sex moderated these associations. Taken together, the current findings advance our understanding of group processes that may produce more salient social influences on students' alcohol use behaviors within proximal peer groups.

Multimorbidity of overweight and obesity alongside anxiety and depressive disorders in individuals with spinal cord injury.

OBJECTIVE: To compare the prevalence of anxiety/depression and overweight/obesity (Aim 1) and the multimorbidity of these conditions (Aim 2) in a sample of adults with and without spinal cord injury (SCI). Aim 3 was to examine whether overweight/obese individuals with SCI differ on the prevalence of anxiety/depressive disorders compared to non-overweight/obese individuals with SCI. DESIGN: Retrospective cohort study. PARTICIPANTS: Individuals ≥16 years old who had patient encounters between January 1, 2011, and February 28, 2018. In total, 761 598 individuals were included, of which 3136 had SCI. MAIN OUTCOME MEASURES: Individuals were identified as diagnosed with SCI, anxiety and/or depressive disorders, and overweight/obesity using the International Classification of Diseases. RESULTS: Age-adjusted odds ratios (ORs) were calculated using logistic regression. In contrast to non-SCI individuals, those with SCI had increased odds of anxiety disorders (OR: 3.58, 95% CI [3.29-3.90]), depressive disorders (OR: 4.33, 95% CI [3.95-4.74]), and overweight/obesity (OR: 3.08, 95% CI [2.80-3.38]). Pertaining to multimorbidity, individuals with SCI had increased odds of having overweight/obesity alongside anxiety disorders (OR: 4.30, 95% CI [3.71-4.98]) and overweight/obesity alongside depressive disorders (OR: 4.69, 95% CI [4.01-5.47]) compared to those without SCI. Individuals with SCI who were diagnosed as overweight/obese had increased odds of having anxiety disorders (OR: 2.54, 95% CI [2.06-3.13]), and depressive disorders (OR: 2.70, 95% CI [2.18-3.36]), relative to non-overweight/obese individuals with SCI. CONCLUSIONS: This work is among the first to find evidence that individuals with SCI are at heightened odds of overweight/obesity alongside anxiety and/or depressive disorders. This early work holds clinical implications for treating these interrelated comorbidities in SCI.

A systematic review of physical activity, sedentary behavior, and substance use in adolescents and emerging adults.

The transition from adolescence into emerging adulthood is marked by changes in both physical activity and substance use. This systematic review characterized associations between movement behaviors (physical activity, sedentary behavior) and frequently used substances (alcohol, cannabis) among adolescents and emerging adults to inform lifestyle interventions that target multiple behavior change outcomes. This systematic review was guided by PRISMA. Electronic databases of PubMed, PsycINFO, and Web of Science were searched from inception through June 25, 2019. The search was designed to identify empirical studies reporting an association between physical activity or sedentary behavior and alcohol or cannabis, with search criteria determining eligibility based on several sampling characteristics (e.g., participants under 25 years of age). After identifying and screening 5,610 studies, data were extracted from 97 studies. Physical activity was positively associated with alcohol use among emerging adults, but the literature was mixed among adolescents. Sedentary behavior was positively associated with alcohol and cannabis use among adolescents, but evidence was limited among emerging adults. Self-report measures were used in all but one study to assess these behaviors. Physical activity is linked to greater alcohol use among emerging adults. Whereas existing studies demonstrate that sedentary behavior might serve as a risk marker for alcohol and cannabis use among adolescents, additional primary research is needed to explore these associations in emerging adults. Future work should also use device-based measures to account for timing of and contextual features surrounding activity and substance use in these populations.

Network centrality, group density, and strength of social identification in college club sport teams.

OBJECTIVE: With the underlying rationale that social identification is related to psychological health and well-being, we aimed to understand how social connections and group structure within college club sport teams relate to students' perceptions of social identification. METHOD: We sampled 852 student-athletes from 35 intact same-sex college club sport teams. Using social network analyses derived from teammates' reports of connections with one another (i.e., time spent outside of sport, and teammate friendships), we computed: outdegree centrality (i.e., self-reported connections with teammates), indegree centrality (i.e., nominations from others), and group-level density. Multilevel models were fit to test the relative effects of outdegree centrality, indegree centrality, and group-level team density on athletes' social identification strength. RESULTS: Outdegree centrality, indegree centrality, and team density were all positively related to the strength of athletes' social identification with their sport team. Examining model results step-by-step, incoming nominations of social connections (i.e., indegree) were associated with social identification beyond the effects of self-reported outdegree centrality. Furthermore, team-level density was significantly related to social identification after accounting for the individual-level effects of centrality. CONCLUSION: Sport is a domain where participants can build social connections with peers, and sport groups offer a salient source for social identification. The current findings indicate that athletes who have greater social connections with teammates may form a stronger sense of social identification. Alongside theoretical contributions to a social identity approach to studying small groups, the current study highlights the utility of studying small groups using social network methodologies.

Social (Un)distancing: Teammate Interactions, Athletic Identity, and Mental Health of Student-Athletes During the COVID-19 Pandemic.

PURPOSE: Physical distancing measures to combat the spread of the novel coronavirus have presented challenges for the mental health and well-being of college students. As campus activities ceased, student-athletes abruptly became isolated from teammates and were no longer able to participate in sport activities that are often central to their identity as an athlete. However, student-athletes who have supportive social connections with teammates during this pandemic may maintain their athletic identity to a greater extent and report better mental health. The present study examined how student-athletes' mental health was associated with teammate social support, connectedness, and changes to athletic identity from before to during COVID-19. METHOD: A sample of 234 student-athletes completed surveys before COVID-19 physical distancing (February 2020), with 135 (63% female) participating in a follow-up in the month following school closures (April 2020). Path models estimated the effects of teammate social support and connectedness (during COVID-19), as well as changes in athletic identity on indices of mental health. RESULTS: Considering all path models tested, student-athletes who received more social support and reported more connectedness with teammates reported less dissolution of their athletic identity and-in most models-reported better mental health and well-being. Indirect effects indicated that student-athletes' change in athletic identity mediated the effects of teammate social support on psychological well-being and depression symptoms. CONCLUSIONS: In addition to advancing theory on how small groups relate to mental health, these findings demonstrate the value in remaining socially connected with peers and maintaining role identities during the COVID-19 pandemic.

Growing into "Us": Trajectories of Social Identification with College Sport Teams Predict Subjective Well-Being.

BACKGROUND: Groups are often a source of social identification that may elicit subjective well-being. When joining and maintaining membership of groups such as sport clubs, it is anticipated that members will experience varying trajectories of identification strength, but it is unclear how these trajectories may relate to well-being. METHOD: Participants were 697 college students (64% female), nested within 35 club-level sport teams. The current study longitudinally assessed students' social identification with sport teams at three timepoints (3-month lags) across a school year to examine the extent that growth trajectories in identification strength predicted indices of well-being (i.e. life satisfaction, happiness, and subjective health) at the end of the school year. RESULTS: Multilevel latent growth modeling revealed that end-of-year well-being was positively predicted by social identification intercepts (b = .24, p = .010) and growth trajectories (b = .75, p < .001). Accounting for baseline identification, steeper increases in social identification (upward trajectories) predicted greater well-being. CONCLUSIONS: Findings support established theory that social identification relates to well-being, while adding novel insights that students may experience unique benefits when their social identity strengthens over the course of a school year. Considering recent declines in college student well-being, groups like sport teams represent a source for social identification that should be fostered throughout the course of one's group membership.

Postpartum Perceived Stress Explains the Association between Perceived Social Support and Depressive Symptoms.

BACKGROUND: Limited research has focused on longitudinal interrelations between perceived social support, perceived stress, and depressive symptoms beyond the first postpartum months. This study tested an alternative primary hypothesis within the stress process model examining whether perceived stress mediated the association between perceived social support and depressive symptoms from 1 to 24 months postpartum. Secondary purposes examined whether these factors 1) changed from 1 to 24 months postpartum and 2) predicted depressive symptoms. METHODS: Women (N = 1,316) in a longitudinal cohort study completed validated measures of perceived social support, perceived stress, and depressive symptoms at 1, 6, 12, 18, and 24 months postpartum via telephone interviews. Analyses examined changes in psychosocial factors (repeated measures analysis of variance) and the extent to which perceived social support and perceived stress predicted depressive symptoms and supported mediation (linear regression). RESULTS: Perceived social support decreased, perceived stress increased, and depressive symptoms remained constant from 1 to 18 months, then increased at 24 months. Low perceived social support predicted 6-month depressive symptoms, whereas perceived stress predicted depressive symptoms at all time points. Perceived stress mediated the association between perceived social support and depressive symptoms across 24 months such that low perceived social support predicted perceived stress, which in turn predicted depressive symptoms. CONCLUSIONS: Intervention scientists may want to focus on strengthening perceived social support as a means to manage perceived stress in an effort to prevent a long-term trajectory of depression.

Longitudinal Associations Between Perceptions of Peer Group Drinking Norms and Students' Alcohol Use Frequency Within College Sport Teams.

BACKGROUND: Students' alcohol use behaviors are shaped by the attitudes and behaviors of others, especially the peers within students' proximal social groups. Explaining the association between perceived drinking norms and alcohol use, researchers propose contradicting pathways that focus on conformity (i.e., social norms predict alcohol use) and projection (i.e., alcohol use predicts perceived norms). The current study examined the extent to which conformity and projection processes were evident in the association between college student alcohol use and the perceived alcohol use norms for students' club sport teams. METHODS: The sample comprised 1,054 college students (61% female) nested in 35 intact same-sex club sport teams. On 3 separate occasions during a single school year (3-month lag), participants reported drinking frequency and perceptions of descriptive and injunctive group drinking norms. We employed random intercepts cross-lagged panel modeling to estimate prospective within-person associations separately from stable trait-like between-person associations. RESULTS: Descriptive and injunctive group drinking norms were both positively related to students' alcohol use frequency at the between-person level. Individuals nevertheless demonstrated variability at the within-person level. Results revealed a strong contemporaneous association between descriptive norms and alcohol use frequency within each timepoint, but no prospective associations. Models including perceptions of injunctive drinking norms demonstrated similar contemporaneous associations with alcohol use frequency, but also identified significant prospective associations signifying conformity. CONCLUSIONS: Findings align with previous research reporting a strong and positive association between student's self-reported alcohol use and subjective peer alcohol use norms. After disentangling within- and between-person effects to probe for conformity and projection processes, the current findings are somewhat contrary to previous research that has reported reciprocal relationships between social norms and alcohol use behavior. Further investigation of the potential conformity and projection mechanisms of social norms is critical to advance norm-based strategies to reduce harm.

A Scoping Review of Recreational Sport Programs for Disabled Emerging Adults.

Purpose: Recreational sport programs are a critical but overlooked pathway for enhancing social participation of emerging adults with disabilities. Specifically, the experiences of recreational sport program members are important for continued community engagement among emerging adults. To address this gap, this scoping review examined the published studies on recreational sport programs for emerging adults with disabilities with the aim of providing future directions for practice (e.g., program instruction) and research (e.g., measurement). Method: Using the PRISMA-SR guidelines, six electronic databases were searched using key terms of disability, age, and recreational sport; findings were extracted and summarized according to the quality parasport participation framework (autonomy, belonging, challenge, engagement, mastery, meaning) and other outcome measures of the included studies. An online 26-item survey was sent to the included studies' authors to further explore the programs' conditions. Results: There were 16,818 records screened with seven articles included. Studies indicate positive outcomes for emerging adults with disabilities immediately following participation in sport programs (e.g., improved self-esteem, autonomy, friendship skills, and balance). No longitudinal studies have been conducted on sustained participation in sport programs or transfer effects of participation. Conclusion: Despite the limited literature, this scoping review provides the foundation for the development of evidence-informed, participant-driven sport programs for emerging adults with disabilities. This study highlights areas for further development for both researches (e.g., evaluating and reporting quality) and practice (e.g., program evaluation).

Program conditions that foster quality physical activity participation experiences for people with a physical disability: a systematic review.

Background: Due to the numerous barriers people with a physical disability face to being physically active, emphasis in practice and research is often placed on creating opportunities for participation. As such, the quality of the experience is often ignored once an individual is participating.Purpose: An understanding of how to create quality physical activity experiences is critical to foster enjoyable and sustained participation. The aim of this systematic review was to identify intervention and/or program conditions that may foster key elements that shape quality participation (QP) experiences.Methods: In all, 24 qualitative and 6 quantitative studies met inclusion criteria. The results of the qualitative studies were synthesized using thematic analysis.Results: The synthesis identified two program conditions as important for fostering QP elements: (1) group-based programing: participating with peers can be linked to belongingness and mastery and (2) leadership: knowledgeable instructors may foster mastery and autonomy. The quantitative studies lacked variability in program conditions and QP elements, which precluded associating specific conditions with elements of a quality experience.Conclusions: Although the qualitative findings highlight two program conditions which may foster QP elements, overall, evaluations of physical activity interventions involving people with disabilities rarely include experiential aspects of participation.Implications for rehabilitationGroup-based programming and leadership are two program conditions that may foster elements of quality participation.Physical activity organizers need to consider group composition. Physical activity programs should consist of peers with a disability, as appropriate, in order to promote belongingness.Physical activity programs should provide disability-specific training to leaders or seek leaders with disability-specific knowledge, in addition to physical activity knowledge and skills.

Perceptions of groupness during fitness classes positively predict recalled perceptions of exertion, enjoyment, and affective valence: An intensive longitudinal investigation.

Group contexts such as fitness classes are popular forms of physical activity, and studying them can uncover new ways to promote exercise adherence. Focusing on the potential for group fitness experiences to vary from class-to-class, we examined how exercisers' dynamic perceptions of groupness relate to recalled perceptions of exercise enjoyment, affective valence, and exertion. These outcome variables are in focus because they are theoretically construed to be determinants of physical activity. Using an intensive sampling methodology across a two-week period, 97 adult exercisers (M age = 42.35 years) completed surveys following each fitness class attended (695 unique responses). Using multilevel confirmatory factor analysis, we confirmed a theorized two-factor structure of groupness at both the within-and between-person levels. Multilevel modeling revealed that class-to-class fluctuations in exercisers' perceptions of groupness explained a considerable portion of variance in recalled perceptions of exertion, enjoyment, and affective valence. Specifically, during classes in which exercisers' perceptions of groupness were relatively higher, exercisers reported more recalled enjoyment, affective valence, and exertion. Focusing on how variability in groupness perceptions may influence exercise adherence, these findings demonstrate the value in fitness classes feeling like authentic groups. In studying the dynamic aspects of group evaluations, the current study makes novel advancements to group theories applied to exercise settings. Perhaps most notably, individuals' variations in their cognitive evaluations of fitness groups were closely linked to their affective responses to exercise.

Social cohesion and peer acceptance predict student-athletes' attitudes toward health-risk behaviors: A within- and between-group investigation.

OBJECTIVES: Collegiate student-athletes often engage in health-risk behaviors such as alcohol misuse and hazing, but the literature in this domain lacks evidence pertaining to how peers shape attitudes towards such behaviors. We investigated how peer acceptance and social cohesion relate to attitudes towards alcohol use, marijuana use, drinking and driving, playing through a concussion, performance enhancing substance use, and hazing. DESIGN: Cross-sectional survey. METHODS: Participants were 387 NCAA athletes from 23 intact teams. Multilevel modeling was used to examine the extent that health-risk attitudes clustered within teams and enabled us to disentangle individual-level and group-level effects of peer acceptance and social cohesion. RESULTS: Intraclass correlation coefficients revealed that health-risk attitudes clustered within teams. At the individual-level, student-athletes who perceived higher levels of peer acceptance, relative to teammates, held riskier attitudes towards alcohol use, playing through a concussion, and hazing. Meanwhile, those who perceived higher levels of social cohesion relative to teammates held less risky attitudes towards playing through a concussion. At the group-level, teams with greater peer acceptance held less risky attitudes towards playing through a concussion, whereas teams with greater social cohesion held riskier attitudes toward playing through a concussion. CONCLUSIONS: These data indicated that health-risk behaviors may cluster within teams, and that peer acceptance and cohesiveness are differentially associated with attitudes toward risky behavior. Given that peer influence is a multilevel phenomenon, it is prudent that prevention efforts leverage social processes within teams, while reducing pressures to engage in risky behaviors.

The Temporal Association Between Physical Activity and Fruit and Vegetable Consumption: A Longitudinal Within- and Between-Person Investigation.

BACKGROUND: Entering college is associated with significant lifestyle changes and the potential adoption of a lifelong lifestyle. This study examined the longitudinal relationship between physical activity (PA) and fruit and vegetable consumption (FVC) in the hopes that findings could inform student health promotion. METHODS: A total of 369 undergraduate students provided complete responses to demographic, PA, and FVC items via an online survey 3 times over a 6-month period. Random intercept cross-lagged panel modeling examined the association between PA and FVC. RESULTS: Models demonstrated a strong fit for both moderate PA and vigorous PA. In both models, FVC, but not PA, was stable across the 3 waves. Neither model revealed a temporal association between PA and FVC. Unlike the moderate PA model, the vigorous PA model revealed a strong positive association between trait-like vigorous PA and trait-like FVC. CONCLUSION: The stability of FVC over time reinforces the importance of facilitating the adoption and maintenance of healthy dietary behaviors among college students, whereas the instability of PA over time highlights the importance of promoting students' PA year round. The absence of a temporal link between PA and FVC indicates that promotion of one behavior should not be assumed to result in improvement of the other.
