Why some homeless individuals are unsheltered: A narrative review of self-reported reasons

The rising rate of unsheltered homelessness is a troubling and important public health issue. This narrative review sought to answer the question: What are the reasons that homeless individuals report for being unsheltered? To identify studies, systematic search methods were applied to PubMed, Google Scholar, and PsycINFO databases using the following eligibility criteria: English-written, peer-reviewed studies published from 2000 to 2023 that reported qualitative or quantitative data related to reasons why homeless individuals in a Western country were unsheltered. After duplicates were removed, 14,690 studies were screened and filtered to 10 final studies that fit all eligibility criteria and were included in the review. Eight of the 10 studies reported qualitative data from interviews and focus groups; the two quantitative studies reported data from interviewer-administered surveys. Across studies, eight thematic categories were identified as barriers to staying in shelters or other sheltered locations: lack of safety, triggers for substance use, strict shelter rules, triggers for substance use, perceived inadequate care, unsanitary conditions, required treatment to participate in housing program, no pet or family accommodations, and lack of accessibility for individuals with disabilities. Together, these findings indicate the delicate balance needed in homeless shelters to have both an inclusive/permissive and structured/safe environment for homeless individuals. Attention to the design and operation of homeless shelters, as well as staff training and accommodation for clients with special needs may improve some of these issues.
