Girls in the juvenile justice system are at high risk for dating violence exposure as well as co-occurring problems with delinquency and sexual risk taking. Despite the multitude of negative outcomes associated with dating violence, no evidence-based preventive interventions exist for juvenile justice girls. This study will advance scientific knowledge by testing the efficacy of a promising, skills-based intervention (Date SMART) on reducing dating violence, delinquency and sexual risk outcomes for a broad range of court-involved, non-incarcerated girls.
