title: An expanded framework to determine physical activity and falls risks among diverse older adults.
abstract: Falling is a major health-related risk among older adults due to injuries, disability, and even death. Although physical activity (PA) can prevent falls, most older adults are inactive due to limited motivation. The purpose was to examine a motivational framework whereby the stages of change (SOC) and PA mediated the relations between the theory of planned behavior constructs and falls risks among 172 diverse older adults (M age = 72.36). The participants were assessed using standardized scales. Based on the path analysis, the hypothesized framework fit the sample data. The SOC and perceived control had significant path coefficients for PA (.48 and .43, respectively), and PA was linked to falls risks (-.54). Subjective norm was mostly associated with the SOC followed by attitude and perceived control. The variance explained in the SOC, PA, and falls risks were 28%, 59%, and 29%, respectively. Health promoters can use the proposed framework to promote PA and decrease falls risk.
