This study evaluated a community-based correctional program in California, in which parolees tested positive on illicit drugs were given the option of going into a treatment program or having their parole revoked and returned to prison in California. Two comparison groups were constructed to assess the treatment effecta propensity-based comparison group extracted from the general parolee population and program dropouts. Although implicitly coercive, some parolees who finished the program were less likely to be reincarcerated 12 months following release than both comparison groups. However, the observed treatment advantage quickly eroded in the second observation year. Savings realized from the incarcerations avoided were more than enough to pay for the program. Findings from this study suggest that boosting participation in reentry services through coercive measures may yield currently unrealized individual and societal benefits. However, systemic efforts are needed to extend the short-term treatment effects. Design and data limitations in the study weaken the persuasiveness of these findings. Methodological implications and policy issues about coerced treatment are discussed.

Therapeutic communities have become increasingly popular among correctional agencies with drug-involved offenders. This quasi-experimental study followed a group of inmates who participated in a prison-based therapeutic community in a California state prison, with a comparison group of matched offenders, for more than 5 years after their initial prison release. Contrary to successes reported elsewhere, this study found no difference in new arrests and returns to prison between therapeutic community participants and the comparison participants after 5 years. Overall, more than 60% of both groups were returned to prison within 2 years following their initial release. After 5 years, the return-to-prison rate reached about 73% for both groups. The average time spent in prison following initial release was about the same for both groups. Rearrest offenses were also similar in both groups. Policy implications are discussed.

This study estimated the impact of an in-prison, therapeutic community (TC) substance abuse treatment program on management costs in a California prison. A deconstruction method was developed to estimate the opportunity cost of staff time and other resources involved in various prison administrative tasks. Compared to “non-treatment” yards within the facility, the TC environment generated lower administrative costs for disciplinary actions, inmate grievances, and major disruptive incidents resulting in lockdowns. These findings suggest that, in addition to their intended rehabilitative outcomes, prison-based TCs may foster institutional environments that help to control prison management costs.

In the late 1990s, California legislators funded a statewide, community-based correctional program intended to reduce parolee recidivism. Overseen by the California Department of Corrections, the Preventing Parolee Crime Program (PPCP) provided literacy training, employment services, housing assistance, and substance abuse treatment to tens of thousands of parolees. The study found that the PPCP produced modest reductions in reincarcerations and parole absconding, creating the potential for substantial long-term cost savings for California taxpayers. Because the PPCP's positive effects were strongest for parolees who completed their services, future program designers and administrators should consider including mechanisms to improve parolee retention and service utilization. This study also points out the potential benefits of incorporating rigorous evaluation plans into the design and implementation of correctional rehabilitation programs.

This was a cost-benefit study of a statewide program involving multiple community-based services for parolees in California. Program effectiveness was assessed by comparing program costs to incarceration costs avoided due to decreases in recidivism. During the first year following parole release, program participants on average stayed out of prison longer than the comparison population. Participants who completed any of the community-based services stayed out of prison substantially longer. The reductions in re-incarceration yielded a net saving of $21 million in incarceration costs over the study period, after the costs of the program and parole supervision were subtracted, or a 47 percent net return on each program dollar invested. This study did not include potential cost savings to other parties in the justice system. These findings suggest future investments in community-based correctional services might produce substantial financial benefits. A fuller apprehension of the potential benefits would benefit from continuing evaluations, including studies employing a true experimental design.
