结果预期是社会认知理论的一个重要组成部分，它与老年人的身体活动有关。然而，这一结构的测量往往采用一维的方法。我们研究了一个理论上一致的三因素（身体，社会和自我评价）的结果预期运动量表在中年和老年人（N = 320; M年龄= 63.8）的有效性。参与者完成了问卷调查，评估结果预期，身体活动，自我效能和健康状况。与竞争模型的假设因素结构的比较表明，三因素模型提供了最佳的数据拟合。结构效度进一步证明了显着的关联与体力活动和自我效能和年龄和健康状况的差异协会。进一步的证据的有效性和应用的社会认知模型的身体活动是必要的。
Outcome expectations, an important element of social cognitive theory, have been associated with physical activity in older adults. Yet, the measurement of this construct has often adopted a unidimensional approach. We examined the validity of a theoretically consistent three-factor (physical, social, and self-evaluative) outcome expectations exercise scale in middle-aged and older adults (N = 320; M age = 63.8). Participants completed questionnaires assessing outcome expectations, physical activity, self-efficacy, and health status. Comparisons of the hypothesized factor structure with competing models indicated that a three-factor model provided the best fit for the data. Construct validity was further demonstrated by significant association with physical activity and self-efficacy and differential associations with age and health status. Further evidence of validity and application to social cognitive models of physical activity is warranted.
