A subset of criminal offenders diverted from prison to treatment return to crime after successful completion of treatment. Identifying correlates of recidivism among treatment completers will improve our ability to help treated offenders to better capitalize on their treatment experiences. Data from 156 mandated clients of long-term residential treatment who successfully completed the Drug Treatment Alternative to Prison (DTAP) program (Brooklyn, New York) were examined. Findings revealed that recidivists among DTAP graduates were younger, had more juvenile arrests, disliked treatment rules, found treatment rules oppressive, viewed treatment as unnecessarily long, and were unemployed and living alone after treatment. Theory and policy implications are discussed. (Contains 3 tables.)
