Utility of the behavioral model in predicting service utilization by individuals suffering from severe mental illness and homelessness.

This study compared the effectiveness of the behavioral model to predict two service utilization variables: case manager visits and total services used. Nearly 4000 individuals who were homeless and suffered from severe mental illness provided data for the study. Enabling variables explained more variance of both service utilization variables than predisposing or need variables. Social support from professionals was the strongest predictor for both service utilization variables.
