Drug Courts: A Conceptual Framework

Structural and process characteristics of drug courts may have a major influence on offender outcomes. However, despite the existence of dozens of outcome evaluations in the drug court literature, it is impossible to draw clear conclusions regarding variability in outcomes in relation to drug court characteristics. We describe existing approaches to the description of drug court structure and process and argue that a new approach is needed. To address that need, we propose a conceptual framework of five drug court dimensions: leverage, population severity, program intensity, predictability, and rehabilitation emphasis. These dimensions, each scorable on a range from low to high, lend themselves to a systematic set of hypotheses regarding the effects of structure and process on drug court outcomes. Finally, we propose quantitative and qualitative methods for identifying such effects.

Reducing Drug Use and Crime among Offenders: The Impact of Graduated Sanctions

The evaluation of the Washington, D.C., Superior Court Drug Intervention Program (SCDIP) compared drug felony defendants randomly assigned to either a docket offering structured graduated sanctions in combination with drug testing and judicial monitoring, or a docket using drug tests and judicial monitoring only. Assignment to the graduated sanctions docket was found to reduce drug use prior to sentencing. Program participants were significantly less likely to use drugs prior to sentencing, and, in the year after sentencing, were significantly less likely to be arrested and and had significantly fewer arrests. This paper describes characteristics of the sanctioning program that appear highly correlated with positive outcomes.

A DECADE OF DRUG TREATMENT COURT RESEARCH

As drug treatment courts have multiplied over the past decade, so too have research evaluations conducted on their implementation and effectiveness. This article explores the decade of drug treatment court research conducted at RAND, starting with the experimental field evaluation of Maricopas drug testing and treatment options to the most current 14-site national evaluation of courts funded in 1995–96 by the Drug Court Program Office. The article presents summaries of findings, a brief description of a drug treatment court typology, and suggestion of where future research might focus.

Assessing the Costs and Benefits Accruing to the Public from a Graduated Sanctions Program for Drug‐Using Defendants

This paper presents a cost-benefit analysis of the returns to the public from reductions in recidivism associated with a graduated sanctioning program for drug felony defendants. Estimates of program costs for operating a court-based drug testing and sanctioning program are presented with estimates of the value of potential benefits of averted criminal incidents and crime control. The results, based on the evaluation of the Superior Court Drug Intervention Program in Washington, D.C., found that the program saved two dollars in averted crime-related costs for every dollar spent on the program. This paper presents explicit description of the methods used to derive these results so that they may be applied to the evaluation of other experimental/quasi-experimental programs.

Evaluation of the Breaking the Cycle Demonstration Project: Jacksonville, FL and Tacoma, WA:

This research presents the results of the evaluation of the Breaking the Cycle (BTC) demonstration project in Jacksonville, FL and Tacoma, WA. The BTC demonstration project tested the feasibility and impact of system-wide intervention designed to reduce drug use among offenders. Specifically, the BTC model was designed to identify drug using felony defendants and then apply a combination of drug testing linked to graduated sanctions and drug treatment to promote abstinence among these defendants. The evaluation of BTC revealed that certain elements of the intervention might not be feasible. However, the results of the quasi-experimental impact evaluation discovered that, in spite of partial program implementation, participation in BTC was associated with reductions in criminal behavior.
