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…

Evidence suggests that co-developed participatory interventions to prevent violence against women and girls (VAWG) may support behavior change. Yet, adolescents are often excluded from intervention development. Moreover, there remains a gap in understanding if intervention co-development can occur online. Our study explored the feasibility of…

In recent years, there has been a notable increase in the prevalence of deliberate self-harm (DSH) among adolescents, which has led to the recognition of this issue as a significant public health challenge. However, school-based prevention programmes for DSH remain scarce. This study aimed to develop, implement, and evaluate the effectiveness of…

Intimate partner violence (IPV) is a global concern. Interventions designed to prevent IPV are often participatory in nature, implemented in face-to-face settings and seek to create 'safe social spaces'. We however do not fully understand how safe social spaces can be created in online spaces. Our study sought to understand the possibility of…

Objective: Latino day labourers (LDLs) in the USA are at increased risk for non-fatal and fatal occupational injuries, which are compounded by stressors that include wage theft, job insecurity and discrimination. This paper describes the development and refinement of Vales+Tú (You are Worthy of More), an injury prevention programme currently being…

Background: Although older adults with intellectual and/or developmental disabilities face high risks of maltreatment, there are few interventions available to reduce these risks. This study describes the development of a research-based intervention that aims to reduce the risks of maltreatment for this population. Method: The development involved…

Background: Educators in rural schools are uniquely situated to address youth mental health disparities, yet often face challenges in delivering mental health supports. This paper describes the process of adapting the evidence-based Coping Power program, a small group prevention program for youth with aggressive behavior problems, to be a…

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…

As evidence-based interventions are scaled, fidelity of implementation, and thus effectiveness, often wanes. Validated fidelity measures can improve researchers' ability to attribute outcomes to the intervention and help practitioners feel more confident in implementing the intervention as intended. We aim to provide a model for the validation of…

Bystanders play an essential role in school bullying prevention. This study examines student bystanders' perceptions of severity and willingness to intervene in scenarios involving physical, verbal, relational, and cyberbullying. It focuses on five distinct victim reactions: pretending nothing happened, seeking help, fighting back, crying, and no…

This three-armed randomized controlled trial examined how moral disengagement and social norms account for change in bullying behavior and their potential as targets of anti-bullying components within separate interventions among 1200 French-speaking Belgian elementary students (48% boys, 9-12 year-olds, 57 classes, nine schools) during 2018-2019…

A systematic review explored the creation and maintenance of community coalitions as effective for alcohol and other drug (AOD) prevention in adolescence. Community coalitions influence the implementation of effective and sustainable community-based prevention via infrastructure supporting development, delivery, and assessment of human service…

This article serves as the first in a series addressing comprehensive suicide prevention programming in the school context. Suicide is currently the second leading cause of death for 10- to 24-year-olds in the United States. As schools are a place where the majority of youth spend a significant amount of time, it follows that they are a natural…

The aim of this study was to test a training and technical assistance program in early care and education (ECE) center-based programs focused on obesity prevention -- Healthy Way to Grow (HWTG). After completing a self-assessment, ECE programs develop actionable policies to improve the wellness environment. Then, they receive individualized…

There has been a growing body of research on best approaches to reduce college men's sexual assault perpetration. While some interventions have successfully decreased perpetrator behavior, very few have accounted for college men's pre-intervention likelihood of offending (i.e., risk status). Considering the difficulties in changing high-risk men's…
