The overall goal of the Homeless Families program is to evaluate time-limited, multi-faceted interventions targeted to homeless mothers with psychiatric, substance use, or co-occurring disorders who are caring for their dependent children. The Homeless Families program is being conducted in two phases. In Phase 2 (the focus of this GFA), study sites will conduct evaluations of their interventions using the cross-site protocol developed by the Steering Committee in Phase I. Study sites will compare their documented intervention with an alternative treatment condition using experimental or quasi-experimental designs. Projects may use additional measures to conduct a site specific study.
