| Abstract: | Abstract This study examined the ability of the behavioral model to predict utilization of five specific services in a sample of individuals who suffered from severe mental illness and who were homeless at baseline. Nearly 4000 individuals from 18 sites provided data at baseline and 12 months later for this study. Hierarchical logistic regression was used to analyze the data. The behavioral model did not explain much of the variance of utilization of medical services, housing services, and public support. The behavioral model did explain a moderate amount of the variance of utilization of psychiatric services and substance abuse services. Enabling variables explained more of the variance of psychiatric services than either predisposing or need variables. In contrast, predisposing and need variables explained more of the variance of utilization of substance abuse services than enabling variables. Social support from professionals and self-perceived need for service were the most consistent predictors of all of the service utilization variables. |
