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.
跌倒在老年人中是一项与健康密切相关的重大风险，会导致受伤、残疾甚至死亡。尽管身体活动（PA）可以预防跌倒，但由于动力有限，大多数老年人缺乏身体活动。本研究旨在探讨一个动机框架，即行为改变阶段（SOC）和身体活动在172名不同的老年人（平均年龄 = 72.36岁）中，如何介导计划行为理论结构与跌倒风险之间的关系。使用标准化量表对参与者进行评估。基于路径分析，假设框架与样本数据拟合良好。SOC和感知控制对身体活动具有显著的路径系数（分别为0.48和0.43），且身体活动与跌倒风险相关（-0.54）。主观规范主要与SOC相关，其次是态度和感知控制。在SOC、身体活动和跌倒风险中所解释的方差分别为28%、59%和29%。健康促进者可以使用所提出的框架来促进身体活动并降低跌倒风险。
