Promising research and methodological approaches for health behavior research with homeless persons

High-risk health behaviors have high prevalence among homeless persons prompting substantial research on health behavior and behavior change strategies within the population. Previously, much of this research focused solely on the target behavior without consideration of contextual factors that may contribute to the behavior or that may inhibit behavior change. We describe three overlapping trends in homeless health behavior research – longitudinal, qualitative, and participatory – which consider the link between the context of homelessness and health behavior. These approaches contribute to the understanding of the social determinants of health behavior and health and demonstrate opportunities for intervention beyond the individual level.
