Recent research has used the theory of planned behavior (TPB) to predict sleep. However, this research has focused on between-person effects and has failed to capture the intraindividual variability of sleep-related attitudes, subjective norms, perceived behavioral control, and intentions.
The current study sought to characterize the between- and within-day patterns of these constructs.
Participants (N = 79) completed a 1 week ecological momentary assessment protocol in which they reported their attitudes, subjective norms, perceived behavioral control, and intentions toward nightly sleep opportunity four times per day.
Analyses revealed both between- and within-day variability of these constructs, with perceived behavioral control and intentions demonstrating greater variability than attitudes and subjective norms. Mixed linear models revealed that attitudes and subjective norms significantly increased throughout the week, while perceived behavioral control and intentions significantly decreased throughout the day.
The between- and within-day patterns of the TPB constructs highlight important methodological considerations and provide insight into the potential refinement of sleep promotion efforts.
最近的研究使用计划行为理论（TPB）来预测睡眠。然而，这项研究主要关注个体间的影响，未能捕捉到与睡眠相关的态度、主观规范、感知行为控制和意向的个体内变异性。
本研究旨在描述这些结构的个体间和个体内模式。
参与者（N=79）完成了为期 1 周的生态瞬间评估方案，其中他们每天报告四次对夜间睡眠机会的态度、主观规范、感知行为控制和意向。
分析显示，这些结构既有个体间的变异性，也有个体内的变异性，感知行为控制和意向的变异性大于态度和主观规范。混合线性模型显示，态度和主观规范在整个星期内显著增加，而感知行为控制和意向在整个白天显著下降。
TPB 结构的个体间和个体内模式突出了重要的方法学考虑因素，并为睡眠促进努力的潜在改进提供了深入了解。
