We report the results of an evaluation study of a diversion program, operated by the Miami-Dade County Juvenile Assessment Center in Florida. The Post-Arrest Diversion (PAD) program represents an innovative approach to treatment and intervention within the juvenile justice system that utilizes standardized psychosocial risks and needs assessment to provide individual treatment for first-time, non-violent juvenile offenders. The present study evaluated the effectiveness of the PAD program with regard to one-year follow-up recidivism. The sample is comprised of 409 youths (255 male; 154 female) who entered PAD between April and June of 2003. Stepwise, Poisson and OLS regression analyses of the effects of socio-demographic characteristics, type of charges leading to program involvement, recidivism risk level, PAD completion, and arrests while in PAD on the number of recidivism arrests and charges were conducted. The findings suggest that successful completion of PAD significantly reduces recidivism. (Contains 5 tables.)
