Bystander Program Effectiveness to Reduce Violence Acceptance: RCT in High Schools.

Bystander-based violence prevention interventions have shown efficacy to reduce dating violence and sexual violence acceptance at the individual level yet no large randomized controlled trial (RCT) has evaluated this effect at the high-school level and over time. This rigorous cluster-randomized controlled trial addresses this gap by evaluating intervention effectiveness at both school and individual levels. Kentucky high schools were randomized to intervention or control conditions.

RCT Testing Bystander Effectiveness to Reduce Violence.

Introduction: Bystander-based programs have shown promise to reduce interpersonal violence at colleges, yet limited rigorous evaluations have addressed bystander intervention effectiveness in high schools. This study evaluated the Green Dot bystander intervention to reduce sexual violence and related forms of interpersonal violence in 26 high schools over 5 years.

Design: A cluster RCT was conducted.

From empower to Green Dot : successful strategies and lessons learned in developing comprehensive sexual violence primary prevention programming.

This case study describes Kentucky's partnership with the Centers for Disease Control and Prevention (CDC) EMPOWER (Enhancing and Making Programs Work to End Rape) program to enhance the mission and services of existing rape crisis centers to include comprehensive primary prevention programming to reduce rates of sexual violence perpetration. The planning process and the successful implementation of a statewide, 5-year, randomized control trial study of a bystander prevention program (Green Dot), and its evaluation are described. Lessons learned in generating new questions, seeking funding, building relationships and capacity, and disseminating knowledge are presented.
