We examined a brief measure of falls self-efficacy in nursing home residents participating in a pilot randomized controlled trial to study the effects of hip protectors on the prevention of fractures (N = 116, mean age 82 ± 8, 72% female). Internal consistency reliability was acceptable with Cronbach's alpha of .79. Factor analysis supported two factors representing self-efficacy expectations and outcome expectancy. Contrasted groups comparisons and construct validity were examined. We found lower falls self-efficacy in participants who needed help with mobility, in people with lower executive function, and in participants who reported fear of falling. Scores were not associated with prospective falls or adherence with hip protector use. The findings of this study provide preliminary support for the reliability and validity of the scale for future research.
