This project utilized the Program Development Evaluation (PDE) method to assess enhanced services provided to clients of the Baltimore City District Drug Treatment Court (DTC) project from October 2010 through March 2014. Clients received one or more of the following services: buprenorphine-enhanced intensive and standard outpatient addiction treatment, halfway house addiction treatment, transitional housing, health-insurance focused case management, and conflict resolution training and mediation services. Parties worked collaboratively to agree upon goals, objectives and implementation measures, and continued partnership to ensure adherence to the program model. This process and outcome report includes a recidivism analysis comparing DTC participants to those who received services and those who did not. Findings include that those who participated in conflict resolution training reduced the likelihood of arrest, conviction, and sentence of incarceration of 1 or more days post-admittance to DTC or post-service provision. Those who participated in conflict resolution training also lasted a longer period of time (or “survived”) without an arrest and without an arrest leading to a conviction than those who did not participate in conflict resolution training. Data challenges and limitations are also detailed.
