This report describes the results of an exploratory study of juvenile justice programs where managers and practitioners are attempting to build youth interventions with strength-based, positive youth development principles. Previous researchers have not adequately documented how such reforms take place, let alone whether they produce effective results for youth, families, and communities. When juvenile justice programs attempt to incorporate strength-based, positive youth development approaches in their work with young offenders, they will likely face resistance from their own staff and from key stakeholders. This study suggests that it is possible to implement these approaches in juvenile justice settings, but more research is needed to substantiate their effects.
