Youth violence that takes place within school settings exposes youth to serious social, mental and physical consequences that affect education performance, and life opportunities. Previous work shows positive youth development frameworks can promote social-emotional learning by enhancing empathy and building problem-solving and conflict management skills. Theater-based interventions have been shown to enhance social emotional development by privileging youth voices, and building youth capacities and strengths. The current manuscript presents the evaluation of an arts-based and public health framework conducted to assess the development, implementation and impact of a forum theater production, Say Something, Do Something (SSDS) in St. Louis, Missouri. An iterative mixed methods approach was used, starting with observations of productions. Using convenience sampling, we then conducted post interviews of the theater team (n = 8) and school personnel (n = 10). Respondents highlighted that as a result of engagement of school personnel in program development, the language and scenarios presented were relevant to students. Data indicated that SSDS increased student knowledge and changed attitudes, developed student conflict management and problem-solving skills, and improved interpersonal behavior. SSDS also raised awareness of the importance of, and created the foundation for, additional system and policy changes in the schools. Forum theater is an approach that can enhance socio-emotional learning and conflict management among youth. Collaborative initiatives between public health and the arts are poised to uniquely engage community partners, animate interventions, and impact critical public health issues including youth violence prevention.
