对身体活动的社会认知模型进行了测试，使用了从参与一项健康促进研究基线阶段的弗吉尼亚州西南部14个教堂招募的999名成年人（21%为非裔美国人；66%为女性；38%不活动）的数据进行结构方程分析。在该模型中，年龄、种族、社会支持、自我效能和自我调节对参与者的身体活动水平有影响，但结果预期没有影响。在社会认知变量中，自我调节对身体活动的影响最大。独立于自我调节，自我效能几乎没有影响。社会支持作为自我效能和自我调节的直接前因影响身体活动。该模型与数据拟合良好，并解释了不同成年人组身体活动中46%的方差。
A social-cognitive model of physical activity was tested, using structural equation analysis of data from 999 adults (21% African American; 66% female; 38% inactive) recruited from 14 southwestern Virginia churches participating in the baseline phase of a health promotion study. Within the model, age, race, social support, self-efficacy, and self-regulation contributed to participants' physical activity levels, but outcome expectations did not. Of the social-cognitive variables, self-regulation exerted the strongest effect on physical activity. Independent of self-regulation, self-efficacy had little effect. Social support influenced physical activity as a direct precursor to self-efficacy and self-regulation. The model provided a good fit to the data and explained 46% of the variance in physical activity among the diverse group of adults.
