Abstract

This meta-analysis examines more than twenty-five years of evidence to determine whether participation in school-based conflict resolution education (CRE) contributes to reduced antisocial behaviors among youth in kindergarten through twelfth grade in U.S. schools. Evidence from thirty-six studies, representing 4,971 students, shows improvements in antisocial behaviors in CRE participants compared to control groups (Effect Size = .26), with larger effects observed during midadolescence ( ES = .53) and early adolescence ( ES = .22) compared to middle childhood ( ES = .06). Improvements in antisocial behavior outcomes attributable to CRE are significant in both practical and statistical terms and are similar for different CRE program approaches.
