For example, studies have found:
More frequent and recent prison visitation, especially from fathers, siblings, in-laws, and clergy, is associated with reduced recidivism.
- Dr. Grant Duwe and Dr. Valerie Clark (2011)
- The prison visitation study was published in Criminal Justice Policy Review, a peer-reviewed academic journal
Prison-based chemical dependency treatment reduces the risk of recidivism by 17-25 percent.
The Minnesota Comprehensive Offender Reentry Plan (MCORP), a prisoner reentry pilot project, was found to be successful in reducing recidivism.
- Dr. Grant Duwe (2012)
- The MCORP study was published in Justice Quarterly and was the 2013 recipient of the Donal MacNamara Outstanding Journal Publication Award by the Academy of Criminal Justice Sciences.
