Impact of Sources of Strength on adolescent suicide deaths across three randomized trials.

Universal interventions are key to reducing youth suicide rates, yet no universal intervention has demonstrated reduction in suicide mortality through an RCT. This study pooled three cluster-RCTs of Sources of Strength (n=78 high schools), a universal social network-informed intervention. In each trial, matched pairs of schools were assigned to immediate intervention or wait-list. Six schools were assigned without a pair due to logistical constraints. During the study period, no suicides occurred in intervention schools vs four in control schools, that is, suicide rates of 0 vs. 20.86/100,000, respectively. Results varied across statistical tests of impact. A state-level exact test pooling all available schools showed fewer suicides in intervention vs. control schools (p=0.047); whereas a stricter test involving only schools with a randomised pair found no difference (p=0.150). Results suggest that identifying mortality-reducing interventions will require commitment to new public-health designs optimised for population-level interventions, including adaptive roll-out trials.

Violence perpetration prevalence among Colorado (United States) high school students across gender, racial/ethnic, and sexual identities.

Adolescent violence, including sexual violence, homophobic name-calling, and teen dating violence, are public health problems that cause harm to many adolescents in the United States. Although research on the perpetration of these forms of adolescent violence has increased in recent years, little is known about perpetration rates across gender, race/ethnicity, and sexual orientation. To address this gap, the current study descriptively examined perpetration rates between and across different identities, including self-identified race/ethnicity, sexual identity, and gender identity. In Fall 2017, 9th - 11th grade students (N = 4782) at 20 high schools in Colorado (United States) completed a survey that assessed demographics (e.g., race/ethnicity, sexual identity, and gender identity) and various forms of violence perpetration. Compared to female adolescents, male adolescents reported significantly higher perpetration rates for: any sexual violence (27% vs. 17%); sexual harassment (26% vs. 15%); unwanted sexual contact (8% vs. 4%); and homophobic name-calling (61% vs. 38%). Differences in perpetration rates were also observed among various racial/ethnic, sexual, and gender minority students compared to non-minority students. This emphasizes a need for more research on how minority stress that results from the dynamics of intersecting identities and societal systems of power-including racism, sexism, homophobia, and transphobia-contributes to violence perpetration. Evidence-based violence prevention approaches, particularly strategies targeted at changing social norms about violence, gender, and sexuality, need to be tailored and evaluated for students with diverse cultural and social identities to ensure safe school climates for all students.

Longitudinal Associations Between Sexual Victimization and Substance Misuse Among High School Youth in Colorado.

There are consistently high rates of sexual victimization and substance misuse among youth in the United States. Although there is a known relation between sexual victimization and substance use, there is a gap in the research regarding the magnitude and temporality of these associations. This study examined whether latent classes of sexual victimization and help-seeking attitudes longitudinally predict intentions of future substance misuse 7-10 months later. Students from nine Colorado high schools (N = 533; M = age 16 years) completed surveys across two consecutive school semesters. Latent class analysis was used to identify classes of students who experienced at least one form of sexual victimization (e.g., sexual harassment, unwanted sexual contact) according to 13 sexual victimization items, and level of positive attitudes regarding help-seeking for sexual victimization. Classes were compared on demographic characteristics and for distal outcomes of likelihood of future substance misuse (cigarettes, alcohol, cannabis, prescription drugs, and electronic vaping products) using latent class regression, controlling for previous intentions to use. At Time 1, four classes of sexual victimization were identified with two main classes for comparison: low odds of experiencing sexual victimization (60.1% of sample) and high odds of endorsing all forms of sexual victimization (7.7% of sample). The high sexual victimization class had higher proportions of male and transgender students, compared to other classes. At Time 2 (7-10 months later), students in the high sexual victimization class reported a significantly greater likelihood of future cigarette (p = .017) and prescription drug misuse (p = .007) when compared to the low sexual victimization class. There was no evidence that having higher positive attitudes towards help-seeking resulted in lower intentions to use substances in the future. These findings highlight that addressing sexual violence in prevention programming may have crossover effects of reducing substance misuse and other forms of violence among youth.

Supporting Sexual Minority Youth: Protective Factors of Adverse Health Outcomes and Implications for Public Health.

PURPOSE: Sexual and gender minority (SGM) youth (e.g., gay, lesbian, bisexual, questioning, transgender) are systemically impacted by victimization and poor mental health because of discrimination in society. To prevent adverse outcomes, we must understand factors that help communities support and protect SGM youth. This study examined to what extent protective factors longitudinally predict outcomes 2 years later in an effort to inform more sensitive prevention efforts. METHODS: Students from nine Colorado high schools (N = 2,744) completed surveys across four consecutive school semesters (T1 to T4). Structural equation modeling was conducted to determine the longitudinal associations between baseline protective factors (access to medical and counseling services, help-seeking beliefs, trusted adults, family support, peer support, spirituality) and distal adverse outcomes (substance use, depression, suicidal ideation, peer victimization, bullying perpetration, sexual violence victimization and perpetration, homophobic name-calling victimization, and perpetration), by sexual orientation. RESULTS: All protective factors examined, except for access to medical services, were associated with lower likelihood of adverse outcomes. Associations differed across sexual orientations. For students identified as questioning or something other than heterosexual, lesbian, gay, or bisexual, family support is a notable protective factor of depression, peer victimization, bullying perpetration, and sexual violence perpetration. Family support was not significantly protective for these outcomes among heterosexual, lesbian, gay, and bisexual students. CONCLUSIONS: There is no singular protective factor or universally impactful intervention for public health. Public health initiatives should recognize intersectional identities of young people and build strategies that are relevant to specific identities to create more comprehensive and effective programing.

Connecting the Dots: State Health Department Approaches to Addressing Shared Risk and Protective Factors Across Multiple Forms of Violence.

Violence takes many forms, including intimate partner violence, sexual violence, child abuse and neglect, bullying, suicidal behavior, and elder abuse and neglect. These forms of violence are interconnected and often share the same root causes. They can also co-occur together in families and communities and can happen at the same time or at different stages of life. Often, due to a variety of factors, separate, "siloed" approaches are used to address each form of violence. However, understanding and implementing approaches that prevent and address the overlapping root causes of violence (risk factors) and promote factors that increase the resilience of people and communities (protective factors) can help practitioners more effectively and efficiently use limited resources to prevent multiple forms of violence and save lives. This article presents approaches used by 2 state health departments, the Maryland Department of Health and Mental Hygiene and the Colorado Department of Public Health and Environment, to integrate a shared risk and protective factor approach into their violence prevention work and identifies key lessons learned that may serve to inform crosscutting violence prevention efforts in other states.
