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.

Social networks and violence victimization and perpetration among youth: A longitudinal analysis.

Interpersonal violence (IV) is a serious concern for adolescents in the United States that has devastating impacts for individuals and communities. Given the increased importance placed on friendships during adolescence, the purpose of the current study was to examine the extent to which IV experiences cluster within youths' friendship networks. Participants were students (N = 1303) in grades 7th to 10th who completed surveys at the beginning and end of an academic year. Results showed that friends' average perpetration (i.e., the percentage of the friends they nominated who perpetrated IV) was strongly associated with likelihood of individual perpetration at baseline but not at the follow-up. For victimization, friends' average report of victimization (i.e., the percentage of the friends they nominated who were victimized) was associated with higher likelihood reporting of victimization (at both baseline and follow-up). Although future research is needed to understand explanatory mechanisms underlying these findings, it is possible that the effectiveness of prevention initiatives may be enhanced by incorporating peer group information.

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.

Formative research to develop an app to prevent dating and sexual violence and alcohol use among high school youth.

The purpose of this study was to conduct formative research to inform the development of an app, that would simultaneously engage youth and adults, to prevent dating and sexual violence (DSV) and alcohol use (AU). Participants (N = 56) were high school students, parents/guardians, and professionals (e.g., school personnel) from across the United States who participated in online focus groups. Overall, participants had positive perceptions of the utility, helpfulness, and effectiveness of an app to prevent DSV and AU among high school students. Participants provided in depth information about both the content (e.g., local rates of DSV and AU) and features (e.g., skills-based, inclusion of incentives, help button) that the app should include. These preliminary data suggest that future research to develop and pilot an app for both youth and adults to prevent DSV and AU among high school students is warranted.

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.

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.

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.

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.

An examination of bystander opportunity and behavior among adolescents on an Indian reservation.

OBJECTIVE: The present study documented the extent to which Native American youth reported opportunities to intervene in situations of sexual assault and harassment, the types of behaviors that youth engaged in when given the opportunity to intervene, and whether youth were engaging in proactive behaviors to change social norms to be intolerant of these forms of aggression. METHOD: Data come from a survey of 144 Native American middle and high school youth living on an Indian reservation. RESULTS: Analyses revealed that in the past 6 months, 59.1% of participants had opportunity to intervene in a sexual assault and harassment. Opportunity to intervene in sexual assault or harassment was associated with lower feelings of mattering and being older. Among participants who reported bystander opportunity to intervene in sexual assault or harassment, 26.3% reported engaging in positive bystander behavior (e.g., trying to get help or using distraction to help). A closer connection to culture was related to a higher likelihood of engaging in positive bystander action. Roughly half of the participants reported engaging in proactive bystander behavior (e.g., efforts to promote intolerance of these forms of aggression) even in the absence of opportunity. Older youth were more likely to engage in proactive bystander behavior than younger youth. CONCLUSIONS: Bystander-focused programs may be an effective tool to prevent sexual harassment and sexual assault among Native American youth, especially those that include culturally relevant content that helps to strength connections to culture and equipping younger youth with skills to engage in proactive 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.

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.

What relates to length of stay in a sober living home among women with histories of victimization and addiction? A longitudinal analysis.

Despite preliminary research suggesting that length of stay in sober living homes (SLHs) is related to sustained sobriety, little research has examined factors that relate to length of stay in SLHs. The purpose of the proposed exploratory study was to prospectively examine baseline characteristics of women with histories of addiction and victimization as correlates of length of stay in a trauma-informed, gender-responsive SLH. Participants (N = 45) were surveyed three times over a 1-year period. Women were invited to participate within a week of their arrival to the SLH. Nearly two-thirds (62.2%, n = 28) of women stayed under 3 months, and 37.8% (n = 17) of women stayed over 3 months. Whereas older age and greater financial worries were associated with staying over 3 months at the SLH, other variables (e.g., demographics, mental health, recent victimization, recent substance use) were unrelated. Findings indicate that efforts may be needed to ensure that younger women as well as women with less financial worries, who may be less likely to stay for longer periods of times at SLHs, have adequate support for sobriety.

Using intergenerational photovoice to understand family strengths among Native American children and their caregivers.

The purpose of the current study was to examine Native American children and caregivers' perspectives of family and cultural strengths using photovoice and to identify lessons learned from the first-ever implementation of intergenerational photovoice with Native Americans. Participants were Native American, low-income caregivers (n = 6) and their children (n = 12) between the ages of 10 and 15 who participated in six photovoice sessions. The themes that emerged from photos and group discussion included myriad challenges faced by Native American families including exposure to community violence, substance abuse, and criminal offending and incarceration. Themes also emerged that highlighted the strengths of Native families that were used to overcome identified challenges, including religion/spirituality, engagement in traditional cultural practices (e.g., prayer, song, dance), healthy activities (e.g., running, meditation). These data provided foundational information that is currently being used, along with other data, to develop a culturally grounded, strengths-focused, family-based program (Tiwahe Wicagwicayapi [Strengthening/Growing Families in Lakota]) to prevent adverse childhood experiences. We also discuss the challenges of intergenerational photovoice and lessons learned to inform future intergenerational photovoice projects.

Community Conversations on Relationship Violence: Town Variations in Prevention Perceptions through Concept Mapping.

To further develop domestic and sexual violence (DSV) prevention strategies at the community level requires an understanding of how community members in towns think about prevention. Using concept mapping, this study sought to better understand community members' perspectives about what DSV prevention strategies would be most feasible, most effective, and generate the greatest community support within their town. Data were collected across four rural Northern England towns. Participants (>90% White) in each town (total sample size = 119) brainstormed, sorted, and rated between 67 and 90 statements per town (x̅ = 75). Based on the results, a 5-cluster solution of school settings, conversations, individual direct action, community building, and community awareness was identified across all four towns as DSV prevention strategies with one town identifying an additional cluster solution of governance. Despite identifying similar prevention strategies, participants from each town rated these clusters of strategies differently on how feasible, effective, and supported they would be in their community. Overall, our results suggest that there were interesting consistencies across four towns in a similar geographic region in terms of how DSV prevention was described. However, individual communities differed in their views of the feasibility and acceptability of the different strategies. These results suggest that different strategies and higher-level actions may be required to address and prevent DSV within different towns and communities and that community narratives can clarify which specific strategies may encounter fewer barriers to implementation.

Exploring the association between anticipated and actual responses to disclosures of intimate partner violence and sexual assault.

Victims of intimate partner violence (IPV) and sexual assault (SA) commonly disclose their experiences to friends or family members, or within other personal relationships. Disclosure recipients' responses to these disclosures are associated with victims' mental health. Previous research has separately measured both actual responses to IPV/SA and anticipated responses to IPV/SA (e.g., response to a hypothetical scenario) from the perspective of disclosure recipients. Yet, little research has described the association between disclosure recipients' anticipated and actual responses. The aim of the current paper was to use a prospective design to examine the association between disclosure recipients' anticipated and actual responses to IPV/SA, including positive and negative social reactions, perceptions of victim responsibility, empathy, and confusion and ineffectiveness about how to respond. Participants (N = 126 college students aged 18-23; 70.6% women) answered questions about their anticipated responses to a hypothetical IPV/SA disclosure scenario, and then six months later answered the same questions about their actual responses to an actual disclosure of IPV/SA. Although most anticipated and actual responses were significantly associated, associations were moderate in size. Some associations were stronger for participants with a closer relationship to the victim, for participants who had their own victimization history, for women, and for men. Individuals can predict their responses to some degree, but are not totally accurate in doing so.

"I learned that I am worth defending": A process evaluation of a sexual assault prevention program implemented on an Indian reservation.

A great deal of programming has been developed to prevent sexual assault (SA) among adolescents. Few studies examine programming implementation among minority groups and present information about program acceptability among participants and community stakeholders. The purpose of the current study was to examine the acceptability of implementing an empowerment SA self-defense program for adolescent girls on an Indian reservation. Data for the study came from posttest surveys of Native American adolescent girls who participated in an SA prevention program (N = 102) and interviews with community stakeholders, including program participants (N = 18). Results showed that acceptability was high among program participants and community stakeholders. Program participants noted that they liked the program overall and liked components of the programming. Participants noted that they disliked pressure to participate, program length, and missing class. Among community stakeholders, all expressed an overall positive impression of the program, felt that the program had a positive impact on program participants, and appreciated that girls learned to use refusal skills. Community stakeholders provided several programming improvement ideas such as incorporating culturally specific content into the program for future implementation. These findings can be used by other researchers, schools, and practitioners implementing prevention programs with Native American girls.

Preventing Teen Relationship Abuse and Sexual Assault through Bystander Training: Intervention Outcomes for School Personnel.

The purpose of the current study was to examine the impact of exposure to Bringing in the Bystander-High School Curriculum (BITB-HSC) on school personnel, which included a seven session classroom curriculum for ninth through twelfth graders (student curriculum), a bystander training workshop for school personnel (school personnel workshop), and reading materials (handout). We examined how exposure to these various BITB-HSC intervention components was associated with school personnel's knowledge and bystander efficacy, intentions, and barriers specific to student relationship abuse (RA) and sexual assault (SA). Participants were 488 school personnel from 12 high schools in upper New England who completed the 4-month follow-up survey that assessed for intervention exposure (284 participants completed both the baseline and follow-up survey). Whereas 53% of participants were exposed to no intervention components, the other half of the sample were exposed to a combination of intervention components. Higher baseline knowledge and reactive bystander intentions were associated with subsequent exposure to both the student curriculum and the handout, and fewer barriers to bystander action predicted exposure to the school personnel workshop. Exposure to the school personnel workshop, student curriculum, and handout was associated with subsequent greater knowledge, exposure to the student curriculum predicted reactive bystander intentions, and exposure to the handout predicted higher reactive bystander intentions and bystander efficacy. Findings suggest that despite challenges with engagement, exposure to the BITB-HSC components may be a useful tool in improving school personnel's responses to RA and SA among high school students.

Efficacy of a Sexual Abuse Prevention Program with Children on an Indian Reservation.

American Indian youth experience high rates of child sexual abuse (CSA). To date, however, we are aware of no programs that have assessed outcomes associated with an evidence-based CSA prevention program among American Indian children. The purpose of the proposed study was to assess the preliminary acceptability and efficacy of IMpower, a 12-hour curriculum that teaches children how to identify their anatomy, recognize risk, say "no," and tell others if they are being hurt. Using a non-randomized, single-arm pilot trial methodology (N = 48 4th and 5th graders), we found that some domains of children's knowledge of CSA as well as their efficacy to resist an attack increased from pre- to posttest. Moreover, 83% of children reported that they liked IMpower, and 96% of children reported that IMpower helped keep them safe. These data provide preliminary evidence that IMpower is an acceptable and effective CSA prevention initiative that requires further evaluation with American Indian children.

Evaluation of a Bystander-Focused Interpersonal Violence Prevention Program with High School Students.

This study evaluated the effectiveness of a seven-session, bystander-focused, classroom-delivered curriculum (i.e., Bringing in the Bystander-High School Curriculum [BITB-HSC]) in reducing rates of interpersonal violence among high school students. High schools (N = 26) were randomly assigned to the treatment or control condition. In classrooms in treatment schools, students (n = 1081) completed a baseline survey, participated in the BITB-HSC, and completed an immediate post-test, a short-term post-test (approx. 2 months after intervention), and a long-term post-test (approx. 1 year after intervention). Youth in control schools (n = 1322) completed surveys at similar time points but did not participate in the BITB-HSC. Participants were 15.8 years old on average and largely White (85.1%) and heterosexual (84.5%). Students exposed to the BITB-HSC demonstrated significant short-term changes in victim empathy and bystander barriers/facilitators, and long-term changes in rape myths, media literacy, bystander readiness, and knowledge relative to youth in the control condition. Although the BITB-HSC had little long-term impact on actual bystander behavior, there were reductions in some forms of violence among students in the BITB-HSC condition relative to the control condition. Future research is needed to determine if, for whom, why, and in what contexts (e.g., classroom-based versus school-wide initiatives) bystander-focused violence prevention initiatives reduce violence.

Perceptions of Community Norms and Youths' Reactive and Proactive Dating and Sexual Violence Bystander Action.

There is enthusiasm for programs that promote bystander intervention to prevent dating and sexual violence (DSV). However, more information about what facilitates or inhibits bystander behavior in DSV situations is needed. The present cross-sectional survey study investigated whether youth perceptions of adults' behavior and community norms were associated with how frequently youth took action and intervened in DSV situations or to prevent DSV. Specifically, study hypotheses were that youths' perceptions of community-level variables, such as adults' willingness to help victims of DSV or prevent DSV, perceptions of community collective efficacy, and perceptions of community descriptive and injunctive norms disapproving of DSV and supporting DSV prevention, would be associated with how frequently youths took reactive and proactive bystander action. Participants were 2172 students from four high schools in one New England state. ANOVA analyses found that descriptive norms were associated with all actionist behaviors, and perceptions of community cohesion were also consistently associated with them. Injunctive norms were associated, but less consistently, with actionist behaviors. Findings suggest that DSV-related social norms, and descriptive norms and community cohesion in particular, might be relevant to youth DSV bystander behavior.
