This study evaluates the impact of the Family Integrated Transitions (FIT) program on juvenile recidivism. FIT is a family-based intervention for youths with co-occurring substance use and mental health disorders transitioning to home from incarceration. We used administrative data to compare 36-month recidivism rates for youths receiving FIT (N = 105) versus usual care (N = 169). Participation in FIT was associated with a 30% reduction in felony recidivism, but not related to overall, violent felony, or misdemeanor recidivism. This study provides cautious evidence for a promising approach toward reducing felony recidivism for youths with co-occurring disorders transitioning out of the juvenile justice system.
