Evidence-based practice (EBP) applies the principles and techniques of evidence-based decision making to interventions intended to improve, or ameliorate, the social or clinical problems of affected individuals, including offenders with drug abuse problems. This article provides a general overview of EBP, particularly as it applies to treatment and other interventions for offenders with problems involving drugs (including alcohol). The discussion includes a definition of EBP, notes the implications of using EBPs to make policy and clinical decisions, lists the various efforts by government and academic organizations to identify practices that can be considered evidence-based, describes the criteria used by such organizations to evaluate programs as being evidence-based, raises some cautions about the use of EBPs, and ends with some challenges in disseminating and implementing EBPs.

Within prison settings, the reliance on punishment for controlling inappropriate or non-compliant behavior is self-evident. What is not so evident is the similarity between this reliance on punishment and the use of positive reinforcements to increase desired behaviors. However, seldom do inmates receive positive reinforcement for engaging in prosocial behaviors or, for inmates receiving drug treatment, behaviors that are consistent with or support their recovery. This study provides an overview of the development and implementation of a positive behavioral reinforcement intervention in male and female prison-based drug treatment programs. The active involvement of institutional staff, treatment staff, and inmates enrolled in the treatment programs in the development of the intervention along with the successful branding of the intervention were effective at promoting support and participation. However, these factors may also have ultimately impacted the ability of the randomized design to reliably demonstrate the effectiveness of the intervention.

Following research indicating that the treatment needs of women are different from those of men, researchers and clinicians have argued that drug treatment programs for women should be designed to take their needs into account. Such programs tend to admit only women and incorporate philosophies and activities that are based on a social, peer-based model that is responsive to their needs. To assess the relative effectiveness of women-only (WO) outpatient programs compared to mixed-gender (MG) outpatient programs, 291 study volunteers were recruited (152 WO, 139 MG), and a 1-year follow-up was completed with 259 women (135 WO, 124 MG). Using bivariate, logistic regression, and generalized estimating equation analysis, the following four outcomes were examined: drug and alcohol use, criminal activity, arrests, and employment. In both groups, women showed improvement in the four outcome measures. Comparison of the groups on outcomes yielded mixed results; women who participated in WO treatment reported significantly less substance use and criminal activity than women in MG treatment, but there were no differences in arrest or employment status at follow up compared with those in MG treatment.

Studies have shown that methamphetamine (MA) is rapidly becoming the drug of choice for a large number of substance-abusing offenders and is associated with significantly higher levels of HIV risk behaviors prior to their incarceration. Despite these findings, there has been little follow-up research to determine whether these patterns persist among recently paroled offenders after attendance in an in-prison treatment program. This study uses the self-reported data from 812 substance-abusing offenders in a multisite NIDA-funded project to determine whether, either before incarceration or nine months after release from an in-prison substance abuse program, MA use in the past 30 days was associated with increased HIV risk behaviors. The findings indicate that offenders who used MA prior to and after incarceration and treatment report higher levels of HIV risk behaviors compared with offenders with no MA use. Clinical and policy implications of the findings are discussed.

Although evaluations have found prison treatment programs to be generally effective, most studies report that paroled graduates of these programs are much more likely to remain drug-free if they receive continuing treatment in the community. This article reviews research findings on principles of effective correctional treatment and the interventions that have been shown to be effective with drug-abusing parolees or that have been tested with general drug-abusing populations and show promise for use with parolees. The article concludes with a discussion of several issues that clinicians need to consider in adopting and implementing these interventions.

This study assessed a 26-week voucher-based intervention to reinforce abstinence and participation in treatment-related activities among substance-abusing offenders court referred to outpatient treatment under drug diversion legislation (California's Substance Abuse and Crime Prevention Act). Standard treatment consisted of criminal justice supervision and an evidence-based model for treating stimulant abuse. Participants were randomly assigned to four groups, standard treatment (ST) only, ST plus vouchers for testing negative, ST plus vouchers for performing treatment plan activities, and ST plus vouchers for testing negative and/or performing treatment plan activities. Results indicate that voucher-based reinforcement of negative urines and of treatment plan tasks (using a flat reinforcement schedule) showed no statistically significant effects on measures of retention or drug use relative to the standard treatment protocol. It is likely that criminal justice contingencies had a stronger impact on participants' treatment retention and drug use than the relatively low-value vouchers awarded as part of the treatment protocol.

The present study examines the relationship between substance use, mental health problems, and violence in a sample of offenders released from prison and referred to substance abuse treatment programs. Data from 34 sites (n = 1,349) in a federally funded cooperative, the Criminal Justice Drug Abuse Treatment Studies (CJDATS), were analyzed. Among parolees referred to substance abuse treatment, self-reports for the six-month period before the arrest resulting in their incarceration revealed frequent problems with both substance use and mental health. For most offenders with substance use problems, the quantity of alcohol consumed and the frequency of drug use were associated with a greater probability of self-reported violence. Mental health problems were not indicative of increases in violent behavior, with the exception of antisocial personality problems, which were associated with violence. The paper emphasizes the importance of providing substance abuse treatment in relation to violent behavior among offenders with mental health problems being discharged to the community.

In response to growing numbers of drug offenders cycling in and out of the criminal justice system without treatment for underlying drug problems, the judicial system has increasingly adopted drug courts as a strategy to divert these offenders from incarceration to supervised drug treatment. Our aim was to determine if drug court treatment effectiveness could be improved using contingency management, in the form of twice-weekly vouchers, to reinforce abstinence and positive behaviors for 163 clients over 26 weeks. We found no significant differences in outcomes among the study groups, although the Treatment Plan Group that received reinforcement for positive behaviors showed a trend toward poorer performance. We suspect that the influence of the judge within the courtroom had a stronger impact on drug court clients’ attitudes, drug use behaviors and other outcomes than the relatively low-value vouchers awarded as part of the treatment protocol.

Background

Research has indicated that more intense treatment is associated with better outcomes among clients who are appropriately matched to treatment intensity level based on the severity of their drug/alcohol problem. This study examined the differential effectiveness of community-based residential and outpatient treatment attended by male and female drug-involved parolees from prison-based therapeutic community substance abuse treatment programs based on the severity of their drug/alcohol problem.

Methods

Subjects were 4,165 male and female parolees who received prison-based therapeutic community substance abuse treatment and who subsequently participated in only outpatient or only residential treatment following release from prison. The dependent variable of interest was return to prison within 12 months. The primary independent variables of interest were alcohol/drug problem severity (low, high) and type of aftercare (residential, outpatient). Chi-square analyses were conducted to examine the differences in 12-month RTP rates between and within the two groups of parolees (residential and outpatient parolees) based on alcohol/drug problem severity (low severity, high severity). Logistic regression analyses were performed to determine if aftercare modality (outpatient only vs. residential only) was a significant predictor of 12-month RTP rates for subjects who were classified as low severity versus those who were classified as high severity.

Results

Subjects benefited equally from outpatient and residential aftercare, regardless of the severity of their drug/alcohol problem.

Conclusion

As states and the federal prison system further expand prison-based treatment services, the demand and supply of aftercare treatment services will also increase. As this occurs, systems and policies governing the transitioning of individuals from prison- to community-based treatment should include a systematic and validated assessment of post-prison treatment needs and a valid and reliable means to assess the quality of community-based treatment services. They should also ensure that parolees experience a truly uninterrupted continuum of care through appropriate recognition of progress made in prison-based treatment.
