Offenders face a number of significant challenges upon reentry into the community, including securing employment, locating housing, and accessing adequate substance abuse and mental health treatment. These and related issues, if neglected, only bolster rising recidivism rates which have prompted renewed interest in rehabilitation initiatives such as inmate reentry. Many jurisdictions have implemented programs designed to improve offenders' success after prison, but jail reentry programs are far less common. This study examined the effectiveness of one such program, the Auglaize County (OH) Transition (ACT) Program. Using a quasiexperimental design, recidivism was measured a year after release to determine if participation in the ACT Program was predictive of successful reentry. Findings suggest that program participation is strongly related to outcome success as was criminal history. Implications for correctional policy and suggestions for additional jail reentry research are considered. (Author abstract)
