Meta-analysis of moral reconation therapy recidivism results from probation and parole implementations.

A meta-analysis of nine published outcome studies detailing the effects of Moral Reconation Therapy on recidivism in parolees and probationers is presented. The studies included in the meta-analysis had a total of 2,460 MRT-treated individuals and 7,679 individuals in control groups. Only one of the studies included in this report had any affiliation with the developers of MRT. A statistically significant reduction in recidivism, defined as rearrests or reincarcerations, was found (p = .00006) with a transformed effect size of .2238. The results are consistent with a prior meta-analysis on MRT recidivism outcomes with incarcerated felons.
