Faith-based organizations administer many of the prison-based programs aimed at reducing recidivism. Many of these organizations also manage treatment programs for substance abusers, at-risk juveniles, and ex-offenders. Much of the research on religiosity and delinquency indicates that the two are inversely related. Therefore, it seems plausible that faith-based programs, which are rooted in religious organizations, may be effective tools for reducing deviant and criminal behavior. However, it is unclear whether the empirical evidence supports such a claim. This study is an evidence-based assessment of the effectiveness of faith-based programs for reducing recidivism. The results of this study indicate that faith-based programs "work" to reduce recidivism. Directions for future research are discussed. (Contains 1 note and 1 table.)
