title: Psychometric properties of the Task Self-Efficacy Scale for everyday activities in older adults.
abstract: Physical and cognitive factors contribute to independence in daily activities, but the confidence to perform an activity (self-efficacy) also contributes to it. The purpose of this study was to assess the psychometric properties of the Task Self-efficacy Scale (TSE) for confidence in performing daily activities, Validity and reliability were assessed in 278 older adults with scores on all items on the TSE for analysis. Factor analysis revealed two factors (self-care and mobility) explaining 72.42% of the variance in the items. Moderate to large correlations were found between the TSE for Self-Care and TSE for Mobility to exertion (.90 to .93, respectively) and fatigue (-.79 to -.84, respectively) associated with activities assessed in the TSE. The expected differences in TSE were found between those with and without mobility difficulties, fear of falls, and shortness of breath with activity. Cronbach's alpha was .96.
