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…

Diabetes is a significant population health threat. Evidence-based interventions, such as the Centers for Disease Control and Prevention's National Diabetes Prevention Program and diabetes self-management education and support programs, can help prevent, delay, or manage the disease. However, participation is suboptimal, especially among…

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…

Parenting programs have been shown to be effective in preventing and reducing externalising problems in young children. Despite their efficacy, the low rate of initial parental engagement in these programs is a major challenge for clinicians and researchers. Few studies have examined factors associated with rates of initial engagement in parenting…

Despite a robust field of study in healthy romantic relationship education and risk prevention interventions that employ traditional forms of delivery, the field of digital health interventions (DHIs) in healthy relationship programming for adolescents remains undefined. The purpose of this scoping review was to summarize the scope of published…

Beginning in 2010, the U.S. Department of Health and Human Services (HHS) sponsored numerous studies testing the effectiveness of Adolescent Pregnancy Prevention programs on youths' risky sexual behaviors. This article presents results from a meta-analysis of such studies completed between 2015 and 2019 and provided to us by HHS. Studies were…

COVID-19 disproportionally impacted the health and well-being of older adults--many of whom live with chronic conditions--due to their higher risk of dying and being hospitalized. It also created several secondary pandemics, including increased falls risk, sedentary behavior, social isolation, and physical inactivity due to limitations in mobility…

Drug use trends change rapidly among youth, leaving educators and researchers struggling to respond promptly. Widely adopted universal evidence-based interventions (EBIs), such as the Michigan Model for Health™ (MMH), and their delivery systems offer an opportunity to reach large youth populations and reduce the onset and escalation of emerging…

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…
