Introduction: Teen dating violence is a serious public health problem with few effective prevention strategies. This study examines whether the Dating Matters comprehensive prevention model, compared with a standard of care intervention, prevented negative relationship behaviors and promoted positive relationship behaviors. Study design: This longitudinal, cluster-RCT compared the effectiveness of Dating Matters with standard of care across middle school. Standard of care was an evidence-based teen dating violence prevention curriculum (Safe Dates) implemented in eighth grade. Setting/participants: Forty-six middle schools in high-risk urban neighborhoods in four U.S. cities were randomized. Schools lost to follow-up were replaced with new schools, which were independently randomized (71% school retention). Students were surveyed in fall and spring of sixth, seventh, and eighth grades (2012−2016). The analysis sample includes students from schools implementing Dating Matters or standard of care for >2 years who started sixth grade in the fall of 2012 or 2013 and had dated (N=2,349 students, mean age 12 years, 49% female, and 55% black, non-Hispanic, 28% Hispanic, 17% other). Intervention: Dating Matters is a comprehensive, multicomponent prevention model including classroom-delivered programs for sixth to eighth graders, training for parents of sixth to eighth graders, educator training, a youth communications program, and local health department activities to assess capacity and track teen dating violence−related policy and data. Main outcome measures: Self-reported teen dating violence perpetration and victimization, use of negative conflict resolution strategies, and positive relationship skills were examined as outcomes. Imputation and analyses were conducted in 2017. Results: Latent panel models demonstrated significant program effects for three of four outcomes; Dating Matters students reported 8.43% lower teen dating violence perpetration, 9.78% lower teen dating violence victimization, and 5.52% lower use of negative conflict resolution strategies, on average across time points and cohorts, than standard of care students. There were no significant effects on positive relationship behaviors.

This study examines the longitudinal association between baseline adolescent romantic relationship characteristics and later adolescent relationship abuse (ARA). Data are from the first two waves of the National Survey on Teen Relationships and Intimate Violence (STRiV). Girls and boys ages 10 to 18 were recruited randomly from the children of adults participating in a larger national household probability sample panel. About three quarters of the sample identified as White, non-Hispanic. Controlling behavior by a romantic partner consistently predicted later ARA. Higher levels of controlling behavior in the relationship was associated with higher rates of sexual and/or physical ARA victimization and higher rates for similar acts of perpetration. More controlling behavior by the partner was also associated with higher rates of psychological ARA victimization (and higher rates for psychological ARA perpetration). Our results suggest that ARA prevention programs should have explicit discussions of the deleterious effects of controlling behavior with adolescents. Respondents reporting higher feelings of passionate love were also at higher risk of experiencing sexual and/or physical ARA victimization. This finding will need to be considered by clinicians and prevention specialist in their work with youth as a potential risk marker for ARA. Baseline reports of at least one form of ARA were predictive of 1-year follow-up rates of ARA in all of our models, underscoring a long line of research that past aggressive or violent behavior is one of the strongest predictors of current aggressive or violent behavior. We also observed that female respondents were twice as likely to be perpetrators of physical and/or sexual ARA as male respondents. Prevention messaging often is focused on girls as ARA victims and our results imply that messaging should also be directed toward girls as perpetrators.

Highlights• Staff relational practices mediate relations of organization functioning and perceived quality.• Staffing and organizational processes underlie a culture of positive adult-youth interaction.• Staff identifying with the experiences of youth contributes to youths' perceptions of club quality.• Results underscore the importance of workforce development in after-school programs.Abstract Using multilevel data from the national evaluation of Boys and Girls Clubs of America (BGCA), this study examined associations among programmatic structures, workplace and workforce characteristics, and relational practices of program staff as they relate to young people's ratings of their experience attending local clubs. The sample included 57,710 members and 5,231 staff members at 740 BGCA sites throughout the United States. Staff relational practices-including establishing caring relationships, setting high expectations, positive behavior management, encouraging youth input and agency, and cultural sensitivity-explained associations between staffing and organizational functioning and youths' perceptions of the quality of their clubs. Findings suggest a central role of staff relational practices in establishing conditions that youth experience positively, and that staffing and organizational processes, including community engagement and teamwork and efficiency can be viewed as foundations for establishing a culture of positive adultyouth interaction, which in turn can contribute to the promotion of positive youth development. Further, identification with the experiences of youth had a direct association with youths' perceptions of club quality. These results underscore the importance of staff workforce development initiatives as key to improving youth experiences in after-school programs.

This study examined the role of participation in a year‐long school‐based group mentoring program, Project Arrive (PA), on increasing resilience during the first year of high school among students identified as being at high risk for school dropout. Participants were 114, ninth grade students taking part in one of 32 PA mentoring groups, and 71 statistically matched comparison students (53% male, 75% eligible for free/reduced‐price lunch, 62% Latinx). Using a propensity score with inverse probability of treatment weighting (IPTW) to reduce selection bias, and a multi‐level model to account for non‐independence of data within mentoring groups, we examined changes from pre‐test to program exit on seven external resilience resources (developmental supports and opportunities) and four internal resilience assets (personal strengths). At program exit, PA participants had higher adjusted means than comparisons on six external resources, including school support, school belonging, school meaningful participation, peer caring relationships, prosocial peers, and home meaningful participation. PA participants also had higher adjusted means on one internal asset, problem solving. Results point to the promise of group mentoring as an approach for increasing resilience among academically vulnerable adolescents.
