Young women in the juvenile justice system have high rates of prior physical and sexual abuse, substance use and psychiatric disorders. Understandably services usually are based on a therapeutic model to address those needs. Positive Youth Development (PYD) is a complementary alternative format that aims to provide resilience, life competencies, and self efficacy for pro-social actions. We provide a narrative review of PYD programs with a focus on how those relate to youth in closed custody. Sleep and physical activity are two behaviors where incarcerated young women still have personal agency, and we present the additional relevance of those program aspects. We describe methods and findings from a feasibility trial of an existing evidence-based, peer-led program for young women high school athletes used with incarcerated young women. Findings are placed in the context of established models of behavior change. The program was feasible and acceptable, and in this small trial, results demonstrate the format's potential efficacy. PYD may provide a trajectory of success and assets that could durably assist these young women following incarceration.
