70 male felony offenders treated with the cognitive behavioral approach of Moral Reconation Therapy during and after reincarceration were assessed for reincarceration and rearrests five years after their release. They were compared to a nontreated control group of 82 male felony offenders. Reincarceration in the treated group (37.1%) was significantly lower than recidivism in controls (54.9%). Also, the treated group showed fewer rearrests and fewer days of additional sentence.
