This study aimed to investigate the rate at which emergency service use decreased once homeless individuals with mental illnesses were provided stable and independent housing. This study surveyed the current literature, finding that the research was lacking in the specifics as to how hospitalization rates actually decreased and what factors were associated. Thus, the research questions explored in this study were designed to explore the potential reduction rate following housing, what variables affected this reduction, and if supported housing offered more benefits to recovery over standard housing over time. To examine these relationships archival data was obtained on 61 participants involved in treatment with Telecare Corporation and the Orange County Mental Health Agency. A mixed ANOVA was used to assess these variables at 1 year while being homeless and following 1 year being in housing. The findings showed that in this study, type of housing did not have an effect on hospitalization use as well as the 1-year time frame pre and posthousing. Additionally, the specific variables that were assessed also did not show a significant effect on hospitalization reduction rates. It is recommended that this study be replicated for future research with a larger sample size and a longer time frame. This research can inform treatment providers about the recovery process for those who work with clients who are homeless and mentally ill and are just beginning their work toward rehabilitation.
