The Impact of Dual Diagnosis on Drug Court Failure

There is limited research investigating the relationship between dual diagnosis and drug court outcomes. The current study examines the relationship between dual diagnosis and drug court failure by specific failure type. Utilizing data from a large urban drug court in the Southwestern United States, the study finds mixed results regarding the impact of dual diagnosis on drug court failure. Specifically, while there was no evidence that dual diagnosis predicted overall success/failure, dual diagnosis significantly increased the odds of serious program failure (e.g., new offense, absconding, revocation). In contrast, dual diagnosis significantly decreased the odds of less serious failure (e.g., rule violation, relapse).
