The present research evaluated the social, affective, and cognitive processes underlying sustained patterns of health behavior as articulated by the upward spiral theory of lifestyle change. Specifically, we tested whether positive affect experienced during physical activity changes over time in tandem with perceived social integration (PSI), and whether PSI is associated with future activity indirectly through sociality during physical activity, positive affect during physical activity, and positive spontaneous thoughts about physical activity. Adult participants (N = 226) reported daily on their PSI, physical activity behavior, and affect during physical activity for 11 weeks. Once every 2 weeks, they also reported on features of a specific bout of physical activity, including how social it was, positive affect during the activity, and positivity of spontaneous thoughts about physical activity. Multilevel modeling of daily reports over the 11 weeks revealed that as participants' PSI increased, so did their positive affect during physical activity. Further, structural equation modeling of specific reports revealed a significant indirect effect of PSI on future activity through sociality during an intervening instance of physical activity, positive affect experienced during that activity, and positive spontaneous thoughts about physical activity. The findings reported herein provide evidence consistent with the upward spiral theory of lifestyle change and reveal affective and cognitive mechanisms by which social processes may contribute to positive health behavior change and maintenance: namely, positive affect during physical activity and spontaneous thoughts about physical activity. Beyond its utility for evaluating theory, the present study may inform subsequent research aimed at developing sustainable behavior-change interventions.

本研究评估了生活方式改变的上升螺旋理论所阐述的健康行为持续模式背后的社会、情感和认知过程。具体来说，我们测试了在身体活动期间经历的积极情绪是否会随着时间的推移与感知的社会融合（PSI）一起发生变化，以及 PSI 是否通过身体活动期间的社交性、身体活动期间的积极情绪和对身体活动的积极自发想法间接与未来的活动相关联。成年参与者（N=226）在 11 周内每天报告他们的 PSI、身体活动行为和身体活动期间的情绪。每两周一次，他们还报告了特定身体活动的特征，包括社交性、活动期间的积极情绪以及对身体活动的积极自发想法。11 周内的日常报告的多层次建模显示，随着参与者 PSI 的增加，他们在身体活动中的积极情绪也随之增加。进一步，对特定报告的结构方程建模显示，PSI 通过身体活动期间的社交性、该活动期间经历的积极情绪和对身体活动的积极自发想法对未来活动产生显著的间接影响。本报告中的发现提供了与生活方式改变的上升螺旋理论一致的证据，并揭示了社会过程可能有助于积极的健康行为改变和维持的情感和认知机制：即在身体活动期间的积极情绪和对身体活动的积极自发想法。除了对理论进行评估的效用外，本研究还可以为旨在开发可持续行为改变干预措施的后续研究提供信息。（PsycInfo 数据库记录（c）2020 APA，保留所有权利）。
