Exploring the interplay of parenting styles, basic empathy, domestic violence, and bystander behavior in adolescent school bullying: a moderated mediation analysis.

Introduction: This study investigates how parental styles, basic empathy, and family violence influence adolescents' bystander behaviors in school bullying. Methods: A survey was conducted with 1,067 students from three middle schools in southern China. Multifactor logistic regression and a moderated mediation model were employed to analyze the relationships between positive and negative parental styles, basic empathy, and bystander behaviors. Results: The study found significant correlations and predictive relationships: Positive parental styles were strongly associated with increased basic empathy (r = 0.29, p < 0.01) and behaviors that protect victims (r = 0.29, p < 0.01). In contrast, negative parental styles correlated positively with behaviors that support bullying (r = 0.12, p < 0.01) and instances of family violence (r = 0.62, p < 0.01). Basic empathy negatively predicted behaviors that promote bullying (ß = -0.098, p < 0.01) and positively predicted protective behaviors toward victims (ß = 0.249, p < 0.001). Furthermore, family violence weakened the positive effects of positive parental styles on both empathy (ß = -0.075, p < 0.001) and protective behaviors (ß = -0.025, p < 0.01). Conclusion: The findings indicate that positive parental styles indirectly promote adolescents' victim protector behaviors by enhancing their basic empathy, underscoring the importance of emotional cultivation. Meanwhile, family violence weakens the positive impact of these parental styles on basic empathy and protective behaviors, harming adolescents' emotional security and behavioral norms.

The Role of Personality, Just World Beliefs, and Rape Myth Acceptance on Sexual Violence Bystander Intentions.

Socioecological models of bystander intervention suggest that a complex decision-making process is required for a prosocial bystander to intervene, starting with intrapersonal variables of cognition and personality. This study investigates how rape myth acceptance, personality, and just world beliefs impact the frequency of positive bystander intention. The study's sample size consisted of 139 college students. Participants completed an online survey in which they read a vignette and indicated whether they would intervene as a bystander at 25 different instances throughout the vignette. Correlational analyses showed that agreeableness and openness were positively associated with prosocial bystander behavioral intention. A multiple regression analysis found only the belief that the world was a safe and good place was predictive of prosocial bystander behavioral intention. The results suggest that bystander intervention education programs should be revised to address just world beliefs.

Expanding Bystander Behavioral Approaches to Address Racial Violence in Health Research, Pedagogy, and Practice.

A bystander to racial violence is conventionally thought of as someone who witnesses an overt act of racial oppression at the interpersonal level, such as police brutality. However, racial violence in health research, pedagogy, and practice often shows up more covertly, like through epistemic injustice, deficits-based framing, and racial essentialism. We aim to expand how we think about bystanders and perpetrators of racial violence within health institutions, and how antiracism bystander behavioral approaches can be deployed to intervene against such violence. Existing public health antiracism frameworks, such as the Public Health Critical Race Praxis and the PEN-3 Cultural Model, offer valuable constructs and processes through which health practitioners, researchers, and academics can disrupt racial violence. Such antiracism frameworks are well suited to provide individuals within public health and health care with the knowledge, skills, and efficacy to intervene as engaged bystanders against racism within their contexts. To illustrate how constructs within antiracism frameworks can be applied by bystanders in various health settings, we outline case examples of antiracism bystander interventions across three scenarios. The more bystanders there are within health institutions that are equipped with antiracism tools, the more likely normative behaviors uplifting White supremacy within these institutions can be disrupted and health equity can be actualized.

Basic moral sensitivity, moral disengagement, and defender self-efficacy as predictors of students' self-reported bystander behaviors over a school year: a growth curve analysis.

Though school children tend to view peer victimization as morally wrong most do not to intervene on the victim's behalf and some instead choose to aid the victimizer. The aim of this longitudinal study was to investigate how students' defending and pro-aggressive bystander behaviors evolved over the course of one school year and their association to basic moral sensitivity, moral disengagement, and defender self-efficacy. Three-hundred-fifty-three upper elementary school students (55% girls; 9.9-12.9 years of age) each completed self-report surveys at three points during one school year. Results from latent growth curve models showed that pro-aggressive bystander behavior remained stable over the year, whereas defending behavior decreased. Moreover, students who exhibited greater basic moral sensitivity were both less likely to be pro-aggressive and simultaneously more likely to defend. Students with defender self-efficacy were not only associated with more defending behavior at baseline but also were also less likely to decrease in defender behavior over time. Conversely, students reporting a higher degree of moral disengagement were linked to more pro-aggressive behavior, particularly when also reporting lower basic moral sensitivity. These short-term longitudinal results add important insight into the change in bystander behavior over time and how it relates to students' sense of morality. The results also highlight the practical necessity for schools to nurture students' sense of morality and prosocial behavior in their efforts to curb peer victimization.

Bystanders to Sexual Violence: Findings From a National Sample of Sexual and Gender Diverse Adolescents.

Mobilizing bystanders to prevent sexual violence is an increasingly popular prevention strategy. While research has identified characteristics related to opportunity and actions around helping, a more nuanced understanding of how helping behavior and its modifiable levers may differ for youth of various genders is needed. The current study examined bystander-helping behaviors in sexual violence situations in a national, social media-recruited sample of adolescents 14 to 16 years of age. Measures of opportunity and self-reported actions were included in an online survey along with items assessing attitudes related to violence and helping. Given that prevention programs may work differently for cisgender, transgender, and nonbinary young people, between-group differences in amount of opportunity and helping behaviors were examined. Further, we examined correlates of opportunities to help as well as helping behaviors within each group. Overall, few attitude and personal experience characteristics consistently predicted opportunities and behaviors across groups. Group differences that emerged, such as the association between attitudes supportive of rape and lower helping for cisgender but not trans or nonbinary youth, support attending to these group differences in both basic and intervention research to inform tailoring of prevention programs.

Whom Would You Help? The Impact of Perpetrator and Victim Gender on Bystander Behavior During a Sexual Assault.

We examined the impact of perpetrator and victim gender on bystander helping choices and assault perceptions. Participants (32 females, 37 males) read about two simultaneously occurring sexual assaults, indicated which victim they would help, and gave their perceptions of the assaults. We used a within-participants design that fully manipulated the perpetrator and victim gender for both assaults. Results showed female victims of male perpetrators and male victims of female perpetrators were most and least likely to be chosen for help, respectively. Cognitive networks derived from open-ended responses provided insight into the rationale used by participants to make helping decisions in ways that differed by perpetrator and victim gender.

Adolescents High in Callous-Unemotional Traits are Prone to be Bystanders: The Roles of Moral Disengagement, Moral Identity, and Perceived Social Support.

Bystanders are the most common role that adolescents play in bullying episodes, they have considerable influence on the formation of the victim's experience and the perpetrator's behavior. Based on the social-cognitive model, the current study examined the mediating role of moral disengagement in the association between callous-unemotional traits and bystander behavior and the moderating roles of moral identity and perceived social support. Participants included 2,286 Chinese adolescents aged 11-16 years (49.3% boys; Mage = 13.46, SDage = 0.93). The study showed callous-unemotional traits were significantly and positively associated with bystander behavior and this relation was partially mediated by moral disengagement. Moral identity moderated the relation between callous-unemotional traits and moral disengagement as well as callous-unemotional traits and bystander behavior. Perceived social support moderated in the direct and indirect associations between callous-unemotional traits and bystander behavior via moral disengagement. The relation between callous-unemotional traits and moral disengagement and the relation between callous-unemotional traits and bystander behavior became weaker for adolescents with high perceived social support. Surprisingly, the relation between moral disengagement and bystander behavior became stronger for adolescents with a high level of perceived social support. The results supported two specific patterns of perceived social support: stress-buffering and reverse stress-buffering. The present study contributes to our understanding of the key mechanisms underlying the association between callous-unemotional traits and adolescents' bystander behavior.

Study protocol for a randomized controlled trial of RealConsent2.0: a web-based intervention to promote prosocial alcohol-involved bystander behavior in young men.

BACKGROUND: Sexual violence (SV) is a significant, global public health problem, particularly among young adults. Promising interventions exist, including prosocial bystander intervention programs that train bystanders to intervene in situations at-risk for SV. However, these programs suffer from critical weaknesses: (1) they do not address the proximal effect of alcohol use on bystander decision-making and (2) they rely on self-report measures to evaluate outcomes. To overcome these limitations, we integrate new content specific to alcohol use within the context of prosocial bystander intervention into an existing, evidence-based program, RealConsent1.0. The resulting program, RealConsent2.0, aims to facilitate bystander behavior among sober and intoxicated bystanders and uses a virtual reality (VR) environment to assess bystander behavior in the context of acute alcohol use. METHODS: This protocol paper presents the design of a randomized controlled trial (RCT) in which we evaluate RealConsent2.0 for efficacy in increasing alcohol- and non-alcohol-involved bystander behavior compared to RealConsent1.0 or to an attention-control program ("Taking Charge"). The RCT is being implemented in Atlanta, GA, and Lincoln, NE. Participants will be 605, healthy men aged 21-25 years recruited through social media, community-based flyers, and university email lists. Eligible participants who provide informed consent and complete the baseline survey, which includes self-reported bystander behavior, are then randomized to one of six conditions: RealConsent2.0/alcohol, RealConsent2.0/placebo, RealConsent1.0/alcohol, RealConsent1.0/placebo, Taking Charge/alcohol, or Taking Charge/placebo. After completing their assigned program, participants complete a laboratory session in which they consume an alcohol (target BrAC: .08%) or placebo beverage and then engage in the Bystanders in Sexual Assault Virtual Environments (BSAVE), a virtual house party comprising situations in which participants have opportunities to intervene. Self-reported bystander behavior across alcohol and non-alcohol contexts is also assessed at 6- and 12-months post-intervention. Secondary outcomes include attitudes toward, outcome expectancies for, and self-efficacy for bystander behavior via self-report. DISCUSSION: RealConsent2.0 is the first web-based intervention for young men that encourages and teaches skills to engage in prosocial bystander behavior to prevent SV while intoxicated. This is also the first study to assess the proximal effect of alcohol on bystander behavior via a VR environment. TRIAL REGISTRATION: Clinicaltrials.gov, NCT04912492. Registered on 05 February 2021.

(Mis)Perceptions of bystander behaviors and approval: The role of gender-specific perceived norms.

Objective: The current study examines college students' perceptions of same-gender and opposite gender peer norms for bystander behaviors in drinking contexts, as well as the association between perceived norms and participants' willingness to intervene and actual behavior. Method: Participants completed an online survey assessing bystander-related perceived norms, willingness, and behavior. A subset of participants also completed a measure of bystander behavior 4-months later. Results: The results indicated a divergent pattern of normative misperceptions for descriptive and injunctive norms, in which participants overestimated descriptive norms and underestimated injunctive norms. Further, participants who perceived greater perceived injunctive norms reported greater willingness to intervene in the future. While those who perceived that their peers intervened more frequently were more likely to have engaged in bystander behavior at baseline and the four-month follow-up. Conclusions: Results also suggest that the role of gender-specific norms is complex and dependent on participants' own gender. The results indicate the potential value of developing norms-based interventions addressing bystander behaviors and implications for the types of normative misperceptions to target.

Sexual and Gender Minority Men's Bystander Behaviors and Barriers in Response to Witnessing Minor Sexual Aggression.

Objective: Sexual and gender minority (SGM) men experience sexual assault victimization. Encouraging people to become involved when they witness high-risk sexual situations as a prosocial bystander is one preventative mechanism to address sexual assault victimization. However, research assessing the extent that SGM men will intervene when they witness a concerning male-to-male sexual situation and barriers that prevent intervention is lacking. We sought to address these gaps. Method: SGM men (n = 323, Mage = 39.4, range 18-77) completed a web-administered survey. Participants were asked if they had witnessed a high-risk sexual situation and, if so, to describe how they intervened; if they did not intervene, they were asked to explain why not. Data were analyzed using thematic analysis. Results: Nearly 50% (n = 157) of participants reported witnessing a situation that may require intervention, of those men 40% reported involvement. When SGM men intervened, their behaviors included direct and indirect verbal and nonverbal strategies. Reasons for not intervening included not appraising the situation as risky, not viewing it as their responsibility to intervene, or lacking the self-efficacy to act. Conclusion: SGM men reported similar barriers to intervention that heterosexual young adults encounter. Participants also provided a variety of intervention tactics that could be included in bystander intervention initiatives to increase their effectiveness and inclusivity. Additional efforts are needed to modify intervention initiatives at both the individual and community level.

Investigating the effects of autonomy-supportive parenting practices on Italian young adolescent students' motivation to defend victims of bullying: findings on the mediating roles of reactance, depression, anxiety, and stress.

This study investigated the effect of autonomy-supportive parenting practices on young adolescents' self-reported motivation to defend victims of bullying, and the possible mediating effects of factors such as reactance, anxiety, depression, and stress. Methods: Data were collected from 578 Italian public school students ages 10-14 (M age = 11.8 years, 52% boys), who completed a survey in their classroom. The survey included self-report measures of parental orientation, motivation to defend victims of bullying, reactance, anxiety, depression, and stress. Results: We found that autonomy-supportive parenting had a positive effect on autonomous motivation to defend, and that this effect was weakly mediated by reactance. Moreover, autonomy-supportive parenting had a negative effect on extrinsic motivation to defend, which was partially mediated by reactance. Reactance had a positive direct effect on extrinsic motivation to defend, but results also showed that anxiety, depression, and stress did not mediate the effect of autonomy-supportive parenting on motivation to defend. Additionally, autonomy-supportive parenting appeared to play a protective role, being associated with lower levels of reactance, anxiety, depression, and stress. Finally, gender differences were found in our sample, with extrinsic motivation to defend being more prevalent in boys, and autonomous motivation to defend being more prevalent in girls. Girls also reported higher levels of anxiety, depression, and stress, compared to boys. Conclusion: Our findings show that autonomy-supportive parenting practices play a significant role in fostering young adolescents' motivation to defend victims of bullying, and that they are also linked with lower feelings of reactance, anxiety, depression, and stress. We argue that interventions aimed at contrasting bullying and cyberbullying among youths should seek to involve parents more and promote the adoption of more autonomy-supportive parenting practices, due to their consistently proven beneficial effects.

Quantifying College Students' Bystander Behavior to Prevent Sexual Assault and Intimate Partner Violence: Can We Make Improvements?

Sexual assault and intimate partner violence (IPV) are prevalent on college campuses, and bystander intervention programs are often employed as a method for preventing such violence. Unfortunately, there are concerns about current strategies for the measurement and quantification of bystander behavior. Accounting for the opportunity to engage in bystander behavior is theorized to be important, but it remains unclear if doing so improves the validity of the measurement of bystander behavior. The current study compares four methods of quantifying bystander behavior when information about the opportunity to help is also available. First-year undergraduate students (n = 714) from three universities participated. Participants completed the risky situations subscale of the Bystander Behavior Scale, using a modified response scale to measure both bystander behavior and opportunity for such behavior. Measures of criterion variables theorized to be linked with bystander behavior (efficacy to intervene, responsibility to intervene, and moral courage) were also completed. Four types of bystander behavior scores were calculated: breadth, missed opportunity, offset, and likelihood. Likelihood scores, which reflect the likelihood of engaging in bystander behavior when presented with the opportunity to help, correlated more strongly with the criterion variables than other scores. Likelihood scores demonstrated added value in quantifying bystander behavior over other scoring methods. Findings from the current study add to the knowledge of how best to measure and quantify bystander behavior. Such knowledge has significant implications for research on correlates of bystander behavior and evaluations of bystander intervention programs for sexual assault and IPV prevention.

Defender self-efficacy and moral disengagement on social support and bystander behaviors among primary school students: a multilevel moderated mediation model.

This study examines the influence of social support on bystander behaviors, the mediating and moderating effects of moral disengagement and defender self-efficacy at the individual and class levels, and their cross-level interaction. A total of 1310 children in grades 4-6 completed our questionnaire survey at four-time points between October and December in 2021. The questionnaires include the Scale of Perceived Social Support (T1), Moral Disengagement Scale (T2), Defender Self-Efficacy Scale (T3), and Bullying Participant Behaviors Questionnaire (T4). The multilevel moderated mediating model results show that (1) social support negatively predicts reinforcer and outsider behavior and positively predicts defender behavior; (2) defender self-efficacy plays a mediating role between social support and defender behavior, moral disengagement plays a mediating role between social support and bystander behaviors, and defender self-efficacy and moral disengagement play a chain mediation role between social support and bystander behavior; (3a) class-level defender self-efficacy has a direct impact on defender behavior and moderates the relationship between individual defender self-efficacy and reinforcer behavior; and (3b) class-level moral disengagement has a direct impact on defender and outsider behavior and a cross-level moderated role between individual moral disengagement and reinforcer behavior. These results show that the individual and class level defender self-efficacy and moral disengagement can influence the bystander behavior of primary school students, which is of great significance for schools to develop anti-bullying moral education courses and design measures to improve students' anti-bullying self-efficacy.

Impacts of GlobalConsent, a Web-Based Social Norms Edutainment Program, on Sexually Violent Behavior and Bystander Behavior Among University Men in Vietnam: Randomized Controlled Trial.

BACKGROUND: Sexual violence against women is prevalent worldwide. Prevention programs that treat men as allies and integrate a bystander framework are emerging in lower income settings, but evidence of their effectiveness is conflicting. OBJECTIVE: This study aimed to test the impact of GlobalConsent on sexually violent behavior and prosocial bystander behavior among university men in Vietnam. METHODS: We used a double-blind, parallel intervention versus control group design with 1:1 randomization at 2 universities. A total of 793 consenting heterosexual or bisexual men aged 18-24 years who matriculated in September 2019 were enrolled and assigned randomly to GlobalConsent or an attention-control adolescent health education (AHEAD) program. GlobalConsent is an adapted, theory-based, 6-module web-based intervention with diverse behavior change techniques and a locally produced serial drama. AHEAD is a customized, 6-module attention-control program on adolescent health. Both the programs were delivered to computers and smartphones over 12 weeks. Self-reported sexually violent behaviors toward women in the prior 6 months and prosocial bystander behaviors in the prior year were measured at 0, 6, and 12 months. RESULTS: More than 92.7% (735/793) of men in both study arms completed at least 1 program module, and >90.2% (715/793) of men completed all 6 modules. At baseline, a notable percentage of men reported any sexually violent behavior (GlobalConsent: 123/396, 31.1%; AHEAD: 103/397, 25.9%) in the prior 6 months. Among men receiving GlobalConsent, the odds of reporting a high level (at least 2 acts) of sexually violent behavior at the endline were 1.3 times the odds at baseline. Among men receiving AHEAD, the corresponding odds ratio was higher at 2.7. The odds of reporting any bystander behavior at endline were 0.7 times the odds at baseline for GlobalConsent, and the corresponding odds ratio for AHEAD was lower at 0.5. CONCLUSIONS: Compared with a health attention-control condition, GlobalConsent has sustained favorable impacts on sexually violent behavior and prosocial bystander behavior among matriculating university men in Vietnam, who would otherwise face increasing risks of sexually violent behavior. GlobalConsent shows promise for national scale-up and regional adaptations. TRIAL REGISTRATION: ClinicalTrials.gov NCT04147455; https://clinicaltrials.gov/ct2/show/NCT04147455.

"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.

The Effects of Sexual Violence Victimization on Perceived Peer Norms and Social Barriers to Bystander Intervention Among High School Students.

The experience of sexual victimization may lead to increased threat-biased information processing, including increased perceptions of peer attitudes that condone sexual violence. The perception that peers generally condone sexual violence may in turn inhibit survivors of sexual violence from intervening to address risk for harm among their peers. To assess this possibility, the present study examined the direct and indirect association between sexual victimization by a romantic partner, perceived peer rape myth acceptance (RMA), perceived social barriers to bystander intervention, and bystander behaviors over 2-month follow-up in a sample of 843 high school students. Multiple regression path analyses revealed a sequence of positive associations between sexual victimization, perceived peer RMA, and perceived social barriers to bystander intervention, respectively. These direct associations to be significant among girls, but not boys, and revealed an additional negative direct association between perceived social barriers to bystander intervention and bystander behavior over 2-month follow-up among girls. Furthermore, sexual victimization was indirectly associated with decreased bystander behaviors among girls through perceived peer RMA and perceived social barriers to bystander intervention, respectively. Taken together, the current findings highlight the importance of addressing misperceptions of peer norms among survivors of sexual violence in bystander intervention programs.

A Systematic Review of Validated Measures of U.S.-Based Bystander Intervention-Related Constructs.

This review aimed to identify U.S.-based, construct-validated measures of bystander intervention. Following PRISMA-P guidelines, electronic databases were searched, and emails were solicited identifying 8,559 articles for title screening. Abstracts and full texts were double screened, resulting in 24 scales meeting inclusion criteria: (a) measured a bystander-related construct in a situation where there was a potential for actual or perceived imminent physical or emotional harm, (b) written in English, and (c) statistically validated on U.S. samples. Most scales addressed the domain of interpersonal violence (67%), with fewer relating to bias/bullying (8.2%), mental health crises (12.5%), and substance use (12.5%). Most scales (71%) assessed the "take action" step of the situational model. The modal construct represented was intent/willingness/likelihood to intervene (50%). The average number of items on a scale was 14, and most (79%) provided Likert-style response options. None of the validated scales assessing behavior first accounted for an opportunity. Sample sizes ranged from 163 to 3,397, with the modal setting from colleges. Overall, samples were young (21.8 years old), White (75%), women (64%), and heterosexual (89%). Results indicate the need to validate additional measures that capture the "interpreting the situation as problematic" step of the situational model. Scales also need to be validated using diverse samples, particularly within the mental health crisis domain. Across all domains, validated measures need to be developed that first account for an opportunity when measuring actual bystander behavior. The information gleaned can be used to assist researchers in selecting measures and guide future measure development.

Defender self-efficacy and moral disengagement on social support and bystander behaviors among primary school students: a multilevel moderated mediation model

Abstract This study examines the influence of social support on bystander behaviors, the mediating and moderating effects of moral disengagement and defender self-efficacy at the individual and class levels, and their cross-level interaction. A total of 1310 children in grades 4-6 completed our questionnaire survey at four-time points between October and December in 2021. The questionnaires include the Scale of Perceived Social Support (T1), Moral Disengagement Scale (T2), Defender Self-Efficacy Scale (T3), and Bullying Participant Behaviors Questionnaire (T4). The multilevel moderated mediating model results show that (1) social support negatively predicts reinforcer and outsider behavior and positively predicts defender behavior; (2) defender self-efficacy plays a mediating role between social support and defender behavior, moral disengagement plays a mediating role between social support and bystander behaviors, and defender self-efficacy and moral disengagement play a chain mediation role between social support and bystander behavior; (3a) class-level defender self-efficacy has a direct impact on defender behavior and moderates the relationship between individual defender self-efficacy and reinforcer behavior; and (3b) class-level moral disengagement has a direct impact on defender and outsider behavior and a cross-level moderated role between individual moral disengagement and reinforcer behavior. These results show that the individual and class level defender self-efficacy and moral disengagement can influence the bystander behavior of primary school students, which is of great significance for schools to develop anti-bullying moral education courses and design measures to improve students' anti-bullying self-efficacy.

Theoretical mediators of GlobalConsent: An adapted web-based sexual violence prevention program for university men in Vietnam.

Sexual violence remains a global problem that disproportionately affects women. Though sexual violence interventions exist, few have been implemented in low- or middle-income countries, and none in Vietnam for young men. We adapted a sexual violence prevention intervention (RealConsent) developed for college men in the U.S. and conducted a randomized controlled trial of the adapted intervention (GlobalConsent) with college men in Vietnam. We assessed the effects of GlobalConsent on sexually violent behavior and prosocial bystander behavior, directly and through theoretically targeted mediators. The study design entailed a double-blind, parallel intervention-control-group design in two universities. Consenting heterosexual or bisexual men 18-24 years starting university in September 2019 (n = 793) completed a baseline survey and were assigned with 1:1 randomization to GlobalConsent or attention control. Both programs were web-based and lasted 12 weeks. Path analysis was performed to study the mediating effects of cognition/knowledge, beliefs/attitudes, affect, and efficacy/intention variables measured at six months on sexually violent behavior and prosocial bystander behavior measured at 12 months. In parallel multiple-mediator models, initiating GlobalConsent lowered the odds of sexually violent behavior mainly indirectly, via knowledge of sexual violence legality and harm and victim empathy and increased the odds of prosocial bystander behavior directly and indirectly, through knowledge of sexual violence legality and harm and bystander capacities. The efficacious direct and indirect effects of GlobalConsent support the cross-cultural applicability of its underlying theory of change and findings from mediation analyses of its sister program RealConsent, suggesting GlobalConsent's national scalability and adaptability across Southeast Asia.

Preventing sexual violence in sport: Determinants of positive coach-bystander behavior.

Given their central role and position, coaches are instrumental in creating safe sport environments, especially in preventing sexual violence, but little is known about bystander behaviors, hampering the development of effective bystander programs in the context of sport. To identify determining characteristics of bystander behavior, 1,442 Belgian youth sport coaches completed an online questionnaire on bystander-related attitudes, norms, autonomy beliefs, and self-efficacy using two hypothetical scenarios of sexual violence in the sports club. Data were analyzed using confidence interval-based estimation of relevance (CIBER). A total of 127 coaches had witnessed sexual violence over the past year, most but not all intervened. Experiential attitude expectation, instrumental attitude evaluation, perceived referent behavior and approval, and subskill presence were positively associated with coaches' intention to intervene. Of the determinants of positive coach-bystander behavior, attitude and perceived norms proved key constituents for programs addressing sexual violence in youth sport. We conclude that interventions aiming at increasing positive affective consequences, reinforcing the sense of group membership, and strengthening the social norm of intervening in case of signs of sexual violence may be most influential to stimulate positive coach-bystander behavior.
