To produce evidence for factor validity and longitudinal invariance of scales used to examine the theory of planned behavior applied to physical activity.
Self-report questionnaires were administered at 3- (n = 267) and 12-months (n = 333) postpartum.
A single-factor model fit data from the normative beliefs, perceived behavioral control, and behavioral beliefs scales. Attitude and control beliefs were found to be multidimensional. Longitudinal invariance of all scales was supported.
Each scale had strong validity evidence. Future research using these measures will help identify areas for intervention and reveal how changes in these constructs influence physical activity.
为用于检验计划行为理论应用于体育活动的量表的因素效度和纵向不变性提供证据。
在产后3个月(n = 267)和12个月(n = 333)时进行自填式问卷调查。
单因素模型拟合了规范信念、感知行为控制和行为信念量表的数据。态度和控制信念被发现是多维的。所有量表的纵向不变性得到了支持。
每个量表都有强有力的效度证据。使用这些测量方法的未来研究将有助于确定干预领域,并揭示这些构念的变化如何影响体育活动。
