Community-based treatments for persons with serious mental illnesses have consistently proven to be effective. While most studies evaluate assertive community treatment (ACT) programs collectively, distinct models offer different approaches to improving participant outcomes. This study specifically examined the Strengths model versus more traditional ACT programs. Multivariate analyses tested changes in utilization, symptomatology, and clinical outcomes. Both ACT and Strengths reduced inpatient days while increasing outpatient care. Though all patients improved clinically, Strengths demonstrated a significantly greater advantage with symptomatology reduced by half. Findings support both treatment models, but additional clinical gains may be obtained from the Strengths approach.
