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.

感知的社会融合通过积极的影响和自发的思想来预测未来的体育活动。

本研究评估了生活方式变化的向上螺旋理论所阐明的，持续的健康行为模式下的社会，情感和认知过程。具体来说，我们测试了体育锻炼过程中经历的积极影响是否随着感知的社会整合（PSI）随时间而改变，以及PSI是否通过体育锻炼过程中的社交性，体育锻炼过程中的积极影响以及关于以下方面的积极自发想法与未来的活动间接相关：体力活动。成年参与者（N = 226）每天报告其PSI，体力活动行为以及体力活动持续11周的影响。每2周一次，他们还报告了特定体育锻炼的特征，包括社交程度，运动过程中的积极影响，关于体育活动的自发思考的积极性。在过去11周中，对每日报告的多层次建模显示，随着参与者PSI的增加，他们在体育锻炼中的积极影响也随之增加。此外，特定报告的结构方程模型显示，在体育活动的介入期间，PSI通过社交性对未来活动产生了显着的间接影响，在该活动中经历的积极影响以及对体育活动的积极自发思考。本文报道的发现提供了与生活方式改变的向上螺旋理论相一致的证据，并揭示了社交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：在体育锻炼中产生积极影响，以及对体育锻炼的自发思考。除了其用于评估理论的效用之外，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参考。（PsycINFO数据库记录（c）2019 APA，保留所有权利）。
