Gender differences in outcomes from prison-based residential treatment.

This study examines gender similarities and differences in background characteristics, the effectiveness of treatment, and the predictors of post-release outcomes among incarcerated drug-using offenders. The sample of 1,842 male and 473 female treatment and comparison subjects came from a multi-site evaluation of prison-based substance abuse treatment programs. Three-year follow-up data for recidivism and post-release drug use were analyzed using survival analysis methods.
