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.

A Latent Transition Model of the Effects of a Youth-Led Sexual Violence Prevention Initiative on Victimization and Perpetration Trajectories Over Time.

PURPOSE: Latent transition analysis was used to characterize transitions over time in profiles of victimization and perpetration of sexual and related forms of violence (i.e., bullying, dating violence, sexual harassment) over a 2.5-year period among middle and high school students. We also examined how profiles of violence varied as a function of participation in a youth-led sexual violence prevention initiative (Youth Voices in Prevention [Youth VIP]). METHODS: Participants were 2,528 youth (53.3% female, average age = 13.73 years) who completed a survey at five points (every six months) over three academic years (fall 2017-fall 2019). Participation in Youth VIP was tracked by researchers and took place from summer 2018 to fall 2019. RESULTS: Four classes (i.e., low violence class, victimization only class, sexual harassment class, mixed violence class) best captured patterns of victimization and perpetration experiences. The latent transition analysis showed that the least severe class had the highest stability, with the fewest students transitioning out of this class over time. Results also demonstrated that, overall, participation in at least one Youth VIP event, compared to not participating in any Youth VIP events, related to positive transitions over time to less severe classes. DISCUSSION: Violence experienced by youth is not homogenous, although classes of violence among youth are generally stable over a 2.5 period. Results also provide further evidence that Youth VIP is a promising approach to prevent sexual and related forms of violence and appears to promote transition into less severe classes of violence over time.

Social Network Influences on Adolescent E-cigarette Use.

Background: Determine if individual adolescent vaping is associated with the vaping behavior of their school-based friendships; whether that association stems from peer influence or peer selection; and whether it varies by age. Methods: Two wave longitudinal survey of 1,208 students in one Midwestern US school district. Students were asked if they ever vaped and to name their seven closest friends within the school district. A roster of all eligible students was pre-loaded into the survey to facilitate network data collection. Terms for network exposure, the proportion of vaping friends; and selection, the number of new friends who vape, were created. Logistic regression and Stochastic Actor Oriented Models were used to test both influence and selection effects. Results: A cross-sectional logistic regression model indicated that friend vaping was associated with individual vaping (AOR = 4.96, p < 0.01); and lagged logistic models indicated that increased friend vaping was associated with individual vaping initiation (AOR = 1.72, p < 0.05). Selecting new friends who vape was also associated with becoming a vaper (AOR = 1.25, p < 0.01). Both influence and selection were present for those less than 14 years old. Conclusions: This is the first study to use social network analysis to show that adolescents who vape or initiate vaping are more likely to do so if their friends vape, and/or they make new friends who vape. Prevention and cessation programs should address the role of friend influence and selection on e-cigarette use; particularly at younger ages.

Diffusion effects of a sexual violence prevention program leveraging youth-adult partnerships.

The purpose of the current study was to examine the diffusion effects of a youth-led sexual violence prevention program (i.e., Youth Voices in Prevention [Youth VIP]). Specifically, social network analysis was used to measure the extent to which Youth VIP changed behaviors for 1172 middle and high school youth who did not attend program events but were friends with Youth VIP participants and completed the first and final survey (approximately 2 years apart). Findings suggest that there was considerable interpersonal communication about Youth VIP among the students generated by program participation. Specifically, youth with friends who participated in Youth VIP were more likely to report hearing their friends talk about Youth VIP and reported talking to their friends about Youth VIP compared with those not connected to Youth VIP participants. However, there were no diffusion effects found for behavioral outcomes (i.e., bystander intervention behavior, violence victimization, and perpetration). Given the mixed findings, further research is needed to determine the extent to which youth-led sexual violence prevention initiatives lead to changes in broader community-wide changes in youths' behaviors.

Mixed Methods Community-Engaged Evaluation: Integrating Interventionist and Action Research Frameworks to Understand a Community-Building Violence Prevention Program.

While mixed methods research can enhance studies of intervention outcomes and projects where research itself transforms communities through participatory approaches, methodologists need explicit examples. As the field of interpersonal violence prevention increasingly embraces community-level prevention strategies, it may benefit from research methods that mirror community-building prevention processes. A multiphase mixed methods study with sequential and convergent components assessed the feasibility, and impact of a prevention program to change social norms and increase collective efficacy in towns. Joint display analysis created a nuanced picture of the acceptability, feasibility, and impact of the program. This article contributes to the field of mixed methods research by bridging discussions of "interventionist" studies with models of community-based participatory mixed methods research into a combined community-engaged method.

High School Students' Perceptions of School Personnel's Intentions to Help Prevent Teen Sexual and Dating Violence: Associations with Attitudes and Intended Behaviors.

Adolescents are at high risk for sexual and dating violence (SDV) at school, indicating need for both adolescents and school personnel to engage in bystander behavior to prevent SDV. Adolescents' perceptions of social norms about bystander behavior, including their perceptions about social norms among school personnel, may impact adolescents' own SDV attitudes and intended bystander behavior. Based on social norms theory, the current research examines adolescents who underestimate, accurately perceive, and overestimate school personnel's reactive (responding to a current situation) and proactive (spreading messaging about prevention) bystander behaviors. High school students (N = 3,404; mean age = 15.7; 87.2% White; 87% heterosexual) and school personnel (N = 1,150) from 25 schools completed surveys. Adolescents who underestimated school personnel's reactive and proactive bystander behavior had more accepting attitudes towards violence and less bystander behavior intentions. Correcting misperceived norms about bystander behavior may improve students' own bystander behavior.

The stability of youth popular opinion leaders selected over time using social network analysis.

Community interventions that use social network analysis to identify and involve influential individuals are promising for behavior change. However, youth friendships are often unstable. The current study examined the stability of the youth selected as influential in a friendship social network, that is, the degree to which youth selected at one time point were also selected at subsequent time points. Influential youth, also called popular opinion leaders (POLs), were selected to be part of a community-wide sexual violence prevention initiative. POLs were selected based on high in-degree (number of times an individual was nominated as a best friend by another student). We found that POLs were unstable: only 29.81%-41.01% of POLs were stable across time. The percentage of POLs who were stable decreased across time. No factors (social identities, behavioral, attitudinal) consistently predicted POL stability. Although these findings are in need of replications, social network interventions for youth may need to repeatedly select new POLs to account for instability.

Attendance at a Community-Based, After School, Youth-Led Sexual Violence Prevention Initiative.

Sexual violence (SV) among adolescents is a pervasive public health concern. Research on community-based prevention programs that seek to reach youth outside of school hours is less developed, but suggests positive effects. In the current paper, we examine attendance at community events and overnight retreats for a youth-led SV prevention initiative, Youth Voices in Prevention (Youth VIP) using survey (n = 2539) and short-answer (n = 1177) data from a broad sample of youth in a small urban district in the Great Plains (United States), where Youth VIP took place. Multivariate logistic regression models using multiple imputation sampling were tested for retreat and community event attendance (respectively). The model of retreat attendance found that those with past SV victimization had significantly higher odds of attending retreats and each additional extracurricular activity youth participated in was associated with increased odds of attendance. The model of event attendance found that male youth had significantly lower odds of attending an event and that odds of attending increased with each additional extracurricular activity reported. Age, race, ethnicity, sexual orientation, and bystander denial were not significant predictors of attendance. Short-answer questions, coded with content analysis, found that youth report being more likely to attend if events feature fun activities with their friends, money, or other incentives; in survey questions, youth report lack of time and lack of interest as the most common reasons for non-attendance. Findings suggest that programming that blends social time and recreational activities with SV content may improve youth attendance; additional recruitment may be needed to engage male youth and youth who are less involved in extracurriculars. This study provides important insight into youth attendance-who attends, who does not, and why-that can be leveraged by others when seeking to engage youth in SV prevention.

Prospective Associations Between Pornography Viewing and Sexual Aggression Among Adolescents.

Adolescence is a critical period for sexuality development; this study examined prospective associations between pornography use and sexual aggression using a longitudinal study of middle and high school students surveyed five times across 3 years (mean age = 13.7 years at baseline; 53.2% female; 76.5% White; 21.0% Native American; 88.9% heterosexual). Across waves, 15.7%-29.0% of adolescents had viewed pornography in the past 6 months. Results indicated significant, reciprocal associations between pornography and sexual harassment perpetration that were stronger for male adolescents, and some significant associations between pornography use and subsequent sexual assault perpetration. Findings underscore the need to consider multiple theories of the link between pornography viewing and aggression and need for media literacy sexual education beginning in middle school.

Evaluating the Impact of a Youth-Led Sexual Violence Prevention Program: Youth Leadership Retreat Outcomes.

Involving youth in developing and implementing prevention programs to reduce sexual violence (SV) has the potential to improve prevention outcomes. However, there has been little focus on youth-led SV prevention programs, and limited evaluation research to help guide efforts. The current study examined the effectiveness of Youth Voices in Prevention (Youth VIP) leadership retreats on SV victimization and perpetration, forms of violence related to SV (e.g., bullying), SV bystander behaviors and readiness, and perceptions of norms related to SV prevention. Results identified mixed findings for program impact, with variations in outcomes that can help guide future youth-led prevention program initiatives. Youth attending a large "kick-off" leadership retreat (that was less youth-led that subsequent smaller retreats) later reported more bystander behaviors, but also reported increased perpetration and victimization, compared to non-attending youth. However, youth attending smaller, more focused leadership retreats held during the school year, reported reductions in sexual harassment perpetration and improved bystander behaviors and attitudes compared to non-attending youth. Evaluation of moderator variables suggests that program impact was generally stronger for younger participants, sexual minority youth, and non-White youth (which were largely Native American youth in this sample). Findings suggest promise for youth-led prevention work but also highlight the need for testing the impact of different training structures and modalities. Clinical trials number: NCT03207386.

Engaging Native American Youth and Their Caregivers in Sexual Violence Research: A Case Study Documenting Challenges, Opportunities, and Lessons Learned.

Native Americans (the preferred term of our partners/co-authors) experience high rates of sexual violence, which is rooted in colonization and multiple historical traumas. Sexual violence leads to numerous deleterious outcomes, underscoring the critical need for prevention early in life. Yet, most research to date on sexual violence has not focused on Native American populations, and we know little about the most effective strategies to recruit and retain Native American individuals in sexual violence prevention research. The purpose of the current study, grounded in principles of participatory action research, is to describe strategies that were used to recruit (e.g., traditional feeds, door knocking) and retain (e.g., monetary incentives, ongoing community engagement) Native American youth for a study that sought to assess, via surveys and qualitative interviews, the impacts of a youth-led sexual violence prevention initiative in a small city in the Great Plains. We also collected qualitative data from Native American caregivers regarding their perceptions of research. Overall, 67.9% (n = 545) of eligible Native American youth completed the survey, and school and door knocking were most effective methods of recruitment/enrollment followed by community and school events and texting. Over the course of 3 years of data collection, there were higher rates of attrition among Native American youth compared to white youth, and several factors (e.g., older age, sexual assault victimization) predicted attrition among Native American youth. Native American caregivers' responses reflected on reasons it is hard to engage youth and caregivers in research (e.g., lack of time, distrust) as well as strategies to enhance engagement (e.g., personal connection, providing community resources). Throughout the paper, Native American co-authors and project partners reflect on these findings. Implications for future sexual violence prevention research with Native American youth and their caregivers that uses decolonized, participatory action research methodologies are discussed.

Youth perceptions of prevention norms and peer violence perpetration and victimization: A prospective analysis.

The purpose of the current study is to prospectively examine the extent to which social norms perceptions regarding commitment to ending sexual violence are associated with subsequent peer victimization and perpetration experiences. Two types of social norms perceptions were examined: 1) peer norms (perceptions of norms among other students in their city), and 2) adult norms (perceptions of norms among adults in their city). Participants were 1259 middle and high school youth from a single school district (three high schools and five middle schools) who completed online surveys at two-time points, 6 months apart. Adolescents for whom perceptions of peer norms were one standard deviation or more above and below the mean of actual norms were "over-perceivers" and "under-perceivers," respectively. Overperceivers overestimated their peers' commitment to ending sexual violence, whereas underperceivers underestimated their peers' commitment to ending sexual violence. Other adolescents were "accurate perceivers"; these adolescents were accurate in their estimation of their peers' commitment to ending sexual violence. In general, underperceivers (22.2% of the sample) were more likely than accurate perceivers (77.8% of the sample) to subsequently experience peer-to-peer perpetration and victimization. Adolescents who perceived adults to have a higher commitment to ending sexual violence were less likely to report subsequent perpetration and victimization for some forms of peer-to-peer violence. These findings highlight the potential promise of the social norms approaches to prevent peer-to-peer violence among youth which aligns with increasing calls in the field to integrate these approaches into comprehensive sexual violence prevention.

Caregivers' Perceptions of a Youth-led Sexual Violence Prevention Initiative: A Brief Report.

Sexual and related forms of violence among middle and high school students are pervasive public health issues, and thus, there is a growing emphasis on the development and evaluation of sexual violence prevention efforts for youth. Caregivers such as parents are important partners in this work as they can facilitate youths' involvement (e.g., give them permission to participate, provide instrumental support such as rides), but their perception of their youth's involvement in sexual violence prevention efforts is largely unexplored. The current paper examined caregivers' perceptions of their teens' participation in a community-wide, out-of-school, youth-led sexual violence prevention initiative. Some caregivers of youth who were involved in the initiative (N = 19; 79.9% White; 21.1% Native American) responded to closed- and open-ended questions about what their teen had talked to them about in relation to the initiative, why their teen participated in the initiative, and how involvement impacted their teen. Furthermore, caregivers who attended events themselves responded to questions about what they learned, what they liked best, and what they liked least. Over half of caregivers said that their teens talked to them about bystander intervention, social emotional skills, and what constitutes sexual violence. Perceptions of the initiative were largely positive both in terms of what the teen learned at part of the programming and in caregivers' own experience participating. These results are promising for the role of caregivers in partners in prevention.

Parents Matter: A Descriptive Study of Parental Discussions With Teens About Violence Prevention and Related Topics.

In the current article we examined the extent to which parents and caregivers engage in violence prevention and related discussions with their youth and the correlates (i.e., demographics, confidence, modeling of emotion regulation) of these experiences. We also examined the ways in which parents access prevention-related information to aid in these discussions with their youth. Participants were 142 parents/caregivers of a middle or high school-aged youth. Results suggested that adults reported speaking with youth about less sensitive prevention topics (e.g., bullying) more often than more sensitive topics (e.g., sexual violence). Whereas there were no demographic correlates for the level of confidence in discussing prevention topics with youth, emotion regulation modeling was positively correlated with confidence discussing prevention with youth. Also, parents who identified as White were less likely to discuss more sensitive topics with youth while parents who identified as American Indian were more likely to discuss more sensitive topics with youth and model emotion regulation. Having more confidence discussing prevention with youth positively correlated to discussing more sensitive and less sensitive topics with youth. These results underscore the need for engaging parents in prevention programming. More specifically, these data suggest that programs that builds parents' confidence and comfort in having prevention-related conversations with their youth, especially about more sensitive topics is needed in addition to programming that enhances parents' ability to model emotion regulation skills for their children.

Prevalence and Correlates of Sexual Revictimization in Middle and High School Youth.

Research consistently shows that individuals who experience a sexual assault are at an increased risk to experience a subsequent sexual assault, a phenomenon known as sexual revictimization. However, little research has used a longitudinal methodology to examine rates and correlates of peer-to-peer sexual revictimization in middle and high school youth. The purpose of this study was to address this gap in the literature. Participants were 1,706 youth in Grades 7 to 10 (51.3% female) who completed surveys at the beginning and end of an academic year, approximately 6 months apart. Results showed that the vast majority (n = 1561, 90.4%) of youth reported no sexual victimization at either time point, 125 youth (7.2%) reported sexual victimization at one time point, and 40 youth (2.3%) reported sexual victimization at two time points. Among victims (n = 165), about one quarter (n = 40, 24.2%) were victimized at both time points. Binge drinking, depression, and suicidal thoughts were all higher among multiple and singular victims compared with nonvictims and among multiple victims compared with singular victims. Girls and sexual minorities were more likely to be multiple and singular victims compared with nonvictims and multiple victims compared with singular victims. Older youth were more likely to be multiple and singular victims compared with nonvictims. These data underscore the need for programming that concurrently focuses on mental health and sexual assault risk reduction, especially among high-risk youth.

Do Depression and Binge Drinking Explain the Increased Risk of Sexual Violence Among Sexual Minority Middle and High School Girls?

Sexual violence (SV) occurs at rates higher among sexual minority youth than heterosexual youth, but the mechanisms explaining this higher risk are understudied. We examined if binge drinking and depression explain the higher rates of SV victimization among sexual minority middle and high school girls. Female students (N = 1,145) in Grades 7th to 10th completed a survey that assessed for SV, binge drinking, depression, sexual orientation identification, and sex at birth. Sexual minority girls had higher rates of SV victimization compared with heterosexual girls. Binge drinking and depression fully mediated the relationship between sexual orientation status and SV victimization among girls. SV prevention programming for sexual minority girls are urgently needed. Programs that seek to reduce binge drinking and depression may be especially impactful in reducing the risk of violence among sexual minority girls.

Adolescents' Relationships With Important Adults: Exploring This Novel Protective Factor Against Interpersonal Violence Victimization and Perpetration.

Despite the increasing influence of peers during adolescence, adults continue to play a significant role in impacting the lives of adolescents. Adolescents' relationships with caring adults are associated with a host of positive outcomes, including improved psychosocial, educational, and behavioral outcomes, and reduced problem behaviors. However, research has not explored the influence of relationships with caring adults on adolescent interpersonal violence (AIV) risk. The aim of this paper was to examine the associations between the presence of an important adult (i.e., an adult youth can go to if they need help with a problem or decision) and youth reports of AIV victimization and perpetration. Participants included 2,173 youth (53.5% female, 76.0% White) in grades 7-10 who participated in a multiple baseline study of a youth-led sexual violence prevention project. Data from the second baseline survey were used to conduct eight binary logistic regression models to test the association between the presence of an important adult and each of the victimization and perpetration types (i.e., any, bullying, sexual harassment, sexual and dating violence). Results showed that youth who reported having an important adult reported significantly lower likelihood of reporting any victimization and perpetration, bullying victimization and perpetration, and harassment victimization and perpetration. There were no significant associations between the presence of an important adult and sexual and dating violence victimization and perpetration. Given the potential for relationships with important adults to protect against some forms of AIV victimization and perpetration, prevention strategies should include connecting youth with important, caring adults and training such adults to help promote attitudinal and behavior shifts that foster AIV prevention.

Use of Social Network Analysis to Identify Popular Opinion Leaders for a Youth-Led Sexual Violence Prevention Initiative.

In the current article, we describe an innovative sexual violence (SV) prevention initiative that used social network analysis to identify youth and adult popular opinion leaders who were subsequently trained in best practices in SV prevention (e.g., bystander intervention) at a kickoff event (i.e., camp) of the initiative. We provide information on recruitment strategies, participation rates and how those rates varied by some demographic factors, reasons for nonattendance, the initial impact of the camp, and lessons learned. Despite challenges with youth and adult engagement, this innovative approach has the potential to transform the way we approach SV prevention among youth.

Age and Sexual Orientation Moderated the Effects of a Bystander-Focused Interpersonal Violence Prevention Program for High School Students.

The objective of the current paper was to identify moderating factors of a bystander-focused violence prevention program for adolescents, Bringing in the Bystander-High School Curriculum. Participants were 2,403 high school students from 25 schools in northern New England (M age = 15.8 years; 50.9% female; 85.1% White, 84.5% heterosexual) who participated in a cluster-randomized controlled trial. We examined impact among different social groups (i.e., by race, gender, age, poverty, sexual orientation) using moderation analyses. The intervention effects for the past 12-month sexual harassment and stalking perpetration were stronger for younger participants and heterosexual participants; poverty, race, and gender did not moderate any program effects. Findings indicate that future prevention research should consider additional targets for older adolescents that may improve intervention program efficacy. An urgent need exists for interventions that are effective for sexual minority adolescents.

Scope and correlates of high school youths' exposure to dating and sexual violence prevention initiatives.

The researchers examined the extent to which high school youth were exposed to dating and sexual violence (DSV) prevention types (e.g., social marketing campaign) across various locations (e.g., in-school) and how exposure to DSV prevention related to perceptions of social norms and collective efficacy. Participants included 877 high school youth who completed in-school surveys across three towns in New England. Most youth (92%) were exposed to DSV prevention. In general, active exposure and active participation, more so than passive exposure, were related to greater perceptions of collective efficacy and perceptions of social norms more intolerant of DSV. Results also suggested that online exposure to DSV prevention was the most consistent correlate of greater perceptions of collective efficacy and perceptions of social norms more intolerant of DSV. These findings provide clues about the types and locations that might be most effective at preventing DSV among youth.
