Disability and disasters: the role of self-efficacy in emergency preparedness.

Although individuals with physical disabilities have special needs regarding preparedness for a natural or human-made disaster, little is known about the factors involved in motivating members of this population to engage in behaviors which reduce the probability of negative health outcomes. This study proposes and empirically tests an integrated theory-based model for individuals with physical disabilities in which perceived self-efficacy for emergency preparedness moderates the relationship between perceived threat and emergency preparedness behaviors. A nationwide convenience cross-sectional sample of 294 adults self-identifying as having a physical disability completed an online survey. The general linear model was used to assess the effects on preparedness of perceived threat, perceived self-efficacy, and their interaction. In addition to the hypothesized moderating effect of self-efficacy, it was found that minimal (if any) relationship exists between perceived threat and preparedness among those who reported low levels of self-efficacy. Results suggest that self-efficacy and perceived threat operate jointly to motivate individuals with physical disabilities to take precautionary steps to reduce the consequential adverse health effects of natural and human-made disasters. These findings have important implications for the design of effective interventions for individuals with disabilities.
