"I Pulled Them Apart and Told Them to Stop": A Mixed-Methods Examination of Bystander Behavior, Preparedness, and Emotional Reaction.

The goals of this mixed-methods study were to examine self-reported behavior of bystanders who intervened in specific situations of potential sexual violence and physical dating violence, to explore their sense of preparedness to intervene, and to assess bystanders' emotional reactions to their self-reported action or inaction when witnessing potential sexual and dating violence. The participants (n = 553, 65.2% female, 76% freshmen, M age = 18.7 years), responded to a sequence of questions pertaining to witnessing and intervening in specific potentially dangerous situations, emotional reactions to their action or inaction, and preparedness. Bystander participants also provided narrative responses describing their behavior. We used joint display analyses to integrate, analyze, and interpret the qualitative and quantitative data. Of the 553 participants, 38% witnessed "a man talking to a woman and she looked uncomfortable," 27% witnessed "someone taking an intoxicated person up to their room," and 39% witnessed "someone grabbing or pushing their boyfriend or girlfriend"; of those who witnessed, the percentage of those who intervened was 42%, 25%, and 19%, respectively. Bystander behavior involved one of 5Ds: distract, direct, delegate, distance, diffuse, or a combination. Although most bystanders did not get involved, most (94.6%) reported that they felt prepared to intervene. For those who intervened, most reported feeling positive about their action; however, most who did not intervene reported feeling negative about their inaction. Implications for college bystanders and bystander education programs are discussed.

"A Person I Cared About Was Involved": Exploring Bystander Motivation to Help in Incidents of Potential Sexual Assault and Dating Violence.

The purpose of the present study was to examine what motivates college students to put themselves in harm's way and help their peers in risky situations involving sexual assault and dating violence. College students reported on the frequency of witnessing a wide range of potentially dangerous incidents, whether or not they intervened, why they chose to intervene, what their relationship was to the victim, and reactions to their intervention. A sample of 182 (59.5% female) college students (Mage = 19.3 years) participated. We coded and analyzed narrative responses to the question regarding what influenced their decision to get involved. For female students, relationship to the victim, and, for males, the severity of the situation, were key motivational factors for bystander involvement. Some students reported positive feelings while others reported negative feelings directly related to their involvement. Tapping into the motivations underlying college students' helping behavior will be particularly informative for those designing and implementing bystander intervention programs on college campuses. A better understanding of bystander behavior will not only improve bystander intervention programs but it will also put students in the best position to make informed and responsible choices when faced with a difficult situation.

Relational aggression and victimization during adolescence: A meta-analytic review of unique associations with popularity, peer acceptance, rejection, and friendship characteristics.

INTRODUCTION: This meta-analysis includes 46 studies including 35,468 adolescents (M age = 12.4 years) with a mean sample ages between 10 and 17 years. Just over half of the studies include samples drawn from the U.S. with the remaining samples representing 11 different countries. METHOD: We examined the magnitude of overlap between relational aggression and relational victimization and, using infrequently used semipartial correlations as effect sizes, we examined unique associations of each with peer acceptance, peer rejection, popularity, and positive friendship characteristics. RESULTS & CONCLUSIONS: Results indicate a strong intercorrelation between relational aggression and victimization (r‾ = .48). We found no mean level gender difference in experiences of relational aggression or relational victimization. Relational aggression is positively associated with popularity; victimization is negatively associated with peer acceptance and friendship characteristics. Both, aggression and victimization are positively associated with rejection. We explored method of assessment as a potential source of variability of effect sizes as well as potential publication bias. Future research and implications for prevention and intervention are discussed.

Racial discrimination and cortisol output: A meta-analysis.

RATIONALE: Although the relation between stress and physiology is well documented, attempts at understanding the link between racial discrimination and cortisol output, specifically, have produced mixed results, likely due to study characteristics such as racial/ethnic composition of the samples (e.g., African American, Latino), measures of discrimination, and research design (e.g., cross-sectional, experimental). OBJECTIVES: To estimate the overall association between racial discrimination and cortisol output among racial/ethnic minority individuals and to determine if the association between racial discrimination and cortisol output is moderated by age, race/ethnicity, type of discrimination measure, sex, and research design. RESULTS: Using a random effects model, the overall effect size based on k = 16 studies (19% unpublished) and N = 1506 participants was r¯ = 0.040, 95% CI = -0.038 to 0.117. Studies were conducted predominantly in the U.S. (81%). Notably, experimental studies (r¯ = 0.267) exhibited larger effect sizes compared to non-experimental studies (r¯ = -0.007). Age, race/ethnicity, type of discrimination measure, and sex did not moderate the effect sizes. CONCLUSION: This meta-analysis provides evidence that the measurement of the association between racial discrimination and cortisol is complex, and it offers valuable insight regarding methods and designs that can inform future research on this topic. Limitations and future directions are discussed.

Overt and Relational Aggression Participant Role Behavior: Measurement and Relations With Sociometric Status and Depression.

This study is the first to measure participant role behavior across overt and relational forms of aggression. The Overt and Relational Aggression Participant Role Behavior Scales were designed to measure aggression, assisting, reinforcing, defending, victimization, and outsider behavior during acts of peer aggression in an ethnically diverse sample of 609 adolescents (M age = 12 years). The data fit the hypothesized 12-factor model, and measurement invariance was established across gender. Relational victimization, but not overt victimization, was positively associated with all other relational aggression roles. Each participant role subscale was positively associated with depressive symptoms with the exception of the overt and relational outsider subscales. Future research and intervention efforts should consider overt and relational aggression participant roles, separately.

Bystander interventions for sexual assault and dating violence on college campuses: Are we putting bystanders in harm's way?

OBJECTIVE: The present study investigated the well-being of bystanders who witness and intervene in sexual assault and dating violence situations on campus. PARTICIPANTS: Participants were 321 young men and women from a large university in the southeastern United States. METHODS: Participants completed a survey at the end of the Spring semester of 2015 about risky situations they had witnessed, with follow-up questions about their responses to the situations (eg, whether they intervened or not) and feelings about their responses. Participants also completed standardized measures of posttraumatic stress disorder and depression. RESULTS: Over 90% of the participants reported witnessing at least 1 of the risky events presented to them, and approximately 50% reported intervening in events. Intervening was associated with positive feelings, but traumatic stress symptoms were related to witnessing events and intervening. CONCLUSIONS: Results have direct implications for developing appropriate training programs for bystander intervention programs on college campuses.

Overt and Relational Victimization: A Meta-Analytic Review of Their Overlap and Associations With Social-Psychological Adjustment.

This meta-analytic review includes 135 studies, representing 17 countries, of child and adolescent (ages 4-17) samples of overt and relational peer victimization and examines the magnitude of overlap between forms of victimization and associations with five social-psychological adjustment indices. Results indicate a strong intercorrelation between forms of victimization (r¯ = .72). No gender difference with regard to relational victimization was found, but boys were slightly higher in overt victimization. Overt victimization is more strongly associated with overt aggression; relational victimization is more strongly related to internalizing problems, lower levels of received prosocial behavior from peers, and relational aggression. Both forms are related to externalizing problems. Age and method of assessment were explored as potential sources of variability in effect sizes.

Perceptions of intimacy and friendship reciprocity moderate peer influence on aggression.

Previous research has shown that close friends' influence can exacerbate adolescents' aggressive behavior, but results of studies which examine whether friendships of greater or lesser qualities moderate peer influence effects are inconsistent. The present study tested whether the perception of the positive friendship quality of intimate exchange and friendship reciprocity moderated best friend influence on participant aggression over time. The 243 participants were approximately 12 years old and ethnically diverse. Neither intimate exchange nor reciprocity significantly moderated friend influence on aggression in a simple way, but the interaction of intimate exchange and friendship reciprocity predicted peer influence on participants' aggression over time. Specifically, highly intimate, nonreciprocal best friendships and less intimate, reciprocal best friendships showed greatest influence when friends' proportion of peer nominations for aggression was high. Reciprocity and intimacy should be considered when predicting peer influence on aggression.

Peers' Perceptions of Gender Nonconformity: Associations with Overt and Relational Peer Victimization and Aggression in Early Adolescence.

The current study used reports from 318 early adolescents to examine the associations of peer-reported gender nonconformity with peer- and self-reported overt and relational victimization and aggression and possible sex differences in these associations. Multiple-group structural equation modeling revealed that higher levels of peer-reported gender nonconformity were associated with higher self- and peer-reports of overt and relational victimization and aggression among males and females. The association between peer-reported gender nonconformity and peer-reported overt aggression was moderated by participant sex, such that the association was stronger for females compared to males. Results suggest that perceived gender nonconformity is associated with problematic peer relations, especially among females, in early adolescence and implications of these associations are discussed.

A meta-analytic review of internalizing, externalizing, and academic adjustment among children of deployed military service members.

Parental deployment during military conflicts has the potential to impact child adjustment. As increased numbers of military Service members have children, it is critical to understand the association between military deployment and child adjustment. In order to resolve inconsistencies in the existing literature, we performed a meta-analytic review of 16 studies that report associations of military deployment with internalizing, externalizing, and academic adjustment among children. Results indicate a small association between deployment and poorer adjustment. This association varied across several features of the studies. Age moderation was such that the associations are strongest in middle childhood and weakest during adolescence. The method that adjustment was assessed also moderated this association, such that maladjustment was evident primarily with parents' reports. Study design also moderated associations, such that comparisons to civilian controls indicated associations with maladjustment, whereas comparisons to nondeployed military and prepost comparisons did not. These findings summarize the existing quantitative literature to indicate that parental deployment has a negligible association with child maladjustment and provide a foundation for future research.
