Abstract

The physical and mental health care needs of homeless adults are extensive. However, these needs regularly go unmet. Healthcare use behavior is complex and involves a range of obstacles. As such, self-efficacy, an individual’s belief in his or her ability to perform a given behavior, appears to be a relevant factor in healthcare use. While current theory supports this notion and research has confirmed the role of self-efficacy in health behavior generally, a validated measure of healthcare use self-efficacy has not previously existed. The aim of this study was to develop and validate the Healthcare Use Self-Efficacy List (HUSEL) in a sample of homeless adults. Qualitative data collected from homeless adults (N = 10) and case managers (N = 7) were used to ensure that questionnaire items meaningfully reflect the challenges faced in healthcare utilization. A series of analyses involving a larger sample of homeless of adults (N = 131) demonstrated that the HUSEL has sound validity and reliability properties. Results also indicated that healthcare use self-efficacy is associated with number of non-urgent, ambulatory care visits in the past year, presence of unmet medical/surgical need in the past year, and perceived mental health status. The findings are reviewed in light of the existing literature. Clinical implications and future directions are also discussed.
