The initial data which provided information on the factors contributing to a successful drug treatment court outcome in Delaware are reviewed in this article. This longitudinal study indicates that the strongest predictors of success are stakeholder values related to employment. Factors predicting program completion were found to be race, education, and frequency of drug use. However, it is suggested that these success factors vary with individual characteristics. An ongoing study over a post-treatment period of 24 months will explore whether subsequent outcomes are determined by these same factors, especially drug use relapse and criminal recidivism. Topic areas covered include an overview of research on the drug treatment court movement that has been conducted in the United States; the Delaware drug user treatment court experience; Delaware's drug offender diversion program; correlates of drug treatment court outcome, such as age, gender, race/ethnicity, education, employment, marital status, and drug use; and study methodology and findings. Tables include information on selected demographic characteristics of the sample, program completion rates, and significance levels; multivariate logistic regression results prediction completion of a treatment program; and treatment completion rates by race and education, and significance levels by race.
