The Effectiveness of Incarceration-Based Drug Treatment on Criminal Behavior: A Systematic Review

Many, if not most, incarcerated offenders have substance abuse problems. Without effective treatment, these substance-abusing offenders are likely to persist in non-drug offending. The period of incarceration offers an opportunity to intervene in the cycle of drug abuse and crime. Although many types of incarceration-based drug treatment programs are available (e.g., therapeutic communities and group counseling), the effectiveness of these programs is unclear. The objective of this research synthesis is to systematically review quasi-experimental and experimental (RCT) evaluations of the effectiveness of incarceration-based drug treatment programs in reducing post-release recidivism and drug relapse. A secondary objective of this synthesis is to examine variation in effectiveness by programmatic, sample, and methodological features. In this update of the original 2006 review (see Mitchell, Wilson, and MacKenzie, 2006), studies made available since the original review were included in an effort to keep current with emerging research. This synthesis of evaluations of incarceration-based drug treatment programs found that such programs are modestly effective in reducing recidivism. These findings most strongly support the effectiveness of therapeutic communities, as these programs produced relatively consistent reductions in recidivism and drug use. Both counseling and incarceration-based narcotic maintenance programs had mixed effects. Counseling programs were associated with reductions in recidivism but not drug use; whereas, incarceration-based narcotic maintenance programs were associated with reductions in drug use but not recidivism. Note that our findings regarding the effectiveness of incarceration-based narcotic maintenance programs differ from a larger review of community-based narcotic maintenance programs (see Egli, Pina, Christensen, Aebi, and Killias, 2009). Finally, boot camp programs for drug offenders had negligible effects on both recidivism and drug use

Spend less and reduce crime: hear how this is done in the United States

International guest speaker, Steve Aos, is the Director of the Washington State Institute for Public Policy. The Institute is responsible for conducting practical, non-partisan research at legislative direction on issues of importance to Washington State. Steve will discuss the Institute’s criminal justice research findings, and how they believe that the key to success is to think more generally about crime. What citizens want is less crime and less taxpayer spending, says Steve. Washington State has learned that only by thinking of the criminal justice system as a whole - from prevention, juvenile justice to adult corrections and sentencing - can one allocate resources across "silos" in such a way to achieve those goals.This event is sponsored by Juvenile Justice NSW

Victims and Offenders

Abstract: In 2006, long-term forecasts indicated that Washington faced the need to construct several new prisons in the following two decades. Since new prisons are costly, the Washington legislature directed the Washington State Institute for Public Policy to project whether there are "evidence-based" options that can reduce the future need for prison beds, save money for state and local taxpayers, and contribute to lower crime rates. The institute conducted a systematic review of all research evidence that could be located to determine what works, if anything, to reduce crime. We found and analyzed 545 comparison-group evaluations of adult corrections, juvenile corrections, and prevention programs. We then estimated the benefits and costs of many of these evidence-based options and found that some evidence-based programs produce favorable returns on investment. This paper presents our findings and describes our meta-analytic and economic methods
