Integrating Assertive Community Treatment and Illness Management and Recovery for Consumers with Severe Mental Illness

This study examined the integration of two evidence-based practices for adults with severe mental illness: Assertive community treatment (ACT) and illness management and recovery (IMR) with peer specialists as IMR practitioners. Two of four ACT teams were randomly assigned to implement IMR. Over 2 years, the ACT–IMR teams achieved moderate fidelity to the IMR model, but low penetration rates: 47 (25.7%) consumers participated in any IMR sessions and 7 (3.8%) completed the program during the study period. Overall, there were no differences in consumer outcomes at the ACT team level; however, consumers exposed to IMR showed reduced hospital use over time.
