Bullying has far-reaching consequences, and effective bullying prevention can have a long-lasting impact on the well-being of many individuals. To confront bullying in schools, the Olweus Bullying Prevention Program (OBPP) has been implemented in Lithuanian schools since 2008. The OBPP has already been implemented in 466 schools and about…

Using a randomized controlled trial, we investigated changes in both sexual harassment (SH) perpetration and victimization of 2104 middle school students in New York City who received divergent saturation and dosage levels of "Shifting Boundaries," an SH prevention program, which was represented by the length of the program. We assessed…

The effectiveness and program mechanisms of a whole-school anti-bullying program that builds on the socio-ecological framework were investigated by applying person-oriented methods of data analyses. A longitudinal cluster randomized control study was utilized comprising 1377 adolescents (48.5% girls, M[subscript age] = 11.7) who participated in a…

Much of the sexual assault prevention literature on the university level focuses on individual institutions' varied efforts to address incidences of sexual assault on their campuses and their outcomes (Donais et al., 2018). While consent education programming has emerged as one such effort, there is a dearth of evaluative literature in this area…

Background: Adolescent suicide is a public health issue, and school is an ideal setting for prevention activities. LEARN is a peer-led gatekeeper training for high school personnel, parents, and students. The purpose of this study was to evaluate the effectiveness of LEARN as a gatekeeper training. Methods: Paired t tests were used to compare pre-…

Sexual violence among adolescents is a major concern. This study examined the impact of the peer-led "Sources of Strength" program on gender-based violence and attitudes dismissive of sexual harassment. Twenty high schools in Colorado were randomized to intervention (n = 11) or waitlist control (n = 9); students (N = 6461; 9th-11th…

Purpose: To examine beliefs about bullying in physical education (PE) among PE preservice teachers and to examine opinions about training received in this area and the strategies they would use to deal with this phenomenon. Method: We interviewed 44 PE-PSTs (M[subscript age] = 23.91; SD = 2.96) from six Spanish universities in semistructured focus…

Diffusion can contribute to the spread of preventive intervention effects from participants to non-participants, but best practices for randomized trials prevent contamination of conditions. These practices conflict with cultural values of community benefit, which are salient among American Indians. This study embedded social network measures…

Objective: Previous research demonstrates that sociocultural appearance pressures and internalization of appearance ideals lead to disordered eating (DE); however, only a subset of individuals exposed to these influences develop clinically significant DE. Identifying moderators of these associations may increase efficacy of targeted preventions…

Educators have embraced the promotion of social emotional development, student well-being, and mental health as essential educational objectives to promote academic readiness and growth. To address known research-to-practice gaps and limited availability of evidence-based, universal high school programs, we took a community-based participatory…

Objective: Campus sexual assault (SA) prevention programs are widely implemented, despite few having strong empirical support. To inform the development and refinement of prevention programs, we collected pilot qualitative data to capture undergraduates' perspectives regarding desirable program characteristics. Participants: Undergraduates…

Objective: Empowerment Self-Defense (ESD) is a sexual violence prevention approach backed by rigorous empirical research, yet its availability on college campuses is limited. This manuscript evaluates the feasibility and efficacy of an ESD program embedded within a university counseling center. Methods: Participants completed an 8-session ESD…

We describe the conceptual framework and practitioner-based study outcomes of a school-based substance use prevention intervention focused on strengthening student commitment to their personal vision. This study found increases related to goal clarity and identification of a mentor following the intervention. We suggest implications for future…

Health-related internet sources should contain accurate, reliable and updated information, and their usability should be high to enable people to navigate successfully. This study aimed to develop interactive Online Infertility Prevention Training (OIPT) and to reveal design principles by evaluating the online training. The development, design,…

Given the prevalence of alcohol and cannabis co-use among college students, prevention for co-use is crucial. We examined hypothetical receptiveness to substance-specific interventions among students who reported co-use. Students who use alcohol and cannabis were more receptive to alcohol interventions than cannabis interventions. Campus…
