Homelessness and First-Episode Psychosis: An Integrative Review.

Abstract

Background: About 115,000 young people in the United States experience a first episode of psychosis (FEP) annually. FEP is associated with functional decline and long-term executive functioning impairment. Schizophrenia is a risk factor for homelessness with up to 20% of individuals diagnosed experiencing homelessness. Homelessness conveys many burdens including higher rates of victimization, incarceration, and substance use. The intersection of homelessness and FEP represents a uniquely vulnerable population undergoing the compounding effects of two highly stigmatizing burdensome experiences that negatively impact health outcomes, treatment engagement, and life expectancy.

Aims: This study reviews the literature to explore what is currently known about the impacts of homelessness on individuals with FEP, knowledge gaps, directions for research, and recommendations for action.

Methods: An integrative review was conducted in April 2023 with APAPsychInfo, APAPsychArticle, Medline, and CINAHL.

Results: This is the first known review to examine available literature on homelessness and FEP. Current literature examines aspects of FEP and homelessness, but not the likely compounding and interacting relationships between multiple variables. Although the associations among variables such as FEP, homelessness, substance use, legal involvement, family involvement, and treatment engagement have not been studied, the literature available may be suggestive of a compounding negative effect on FEP outcomes.

Conclusion: FEP programs should define homelessness, report rates of homelessness, and conduct research examining the compounding effects of homelessness and FEP as well as other factors like race and ethnicity. Research and policy should support housing interventions for homeless individuals to improve treatment engagement and health outcomes.
