Previous research finds initial evidence that affordances of interactivity, agency, and modality can help increase physical activity (PA). However, the cross-sectional nature of these studies provides a snapshot of behavior but does not assess the impact of affordances of technology on in PA behavior. In this study, we bridge this gap and test if features of technology that afford interactivity, agency, and choice of modality will be associated with an increase in PA across time. Guided by the Motivational Technology Model (MTM), we scraped 784 user profiles from the BodySpace App (a social weightlifting smartphone application) at baseline and after 70 days and establish the relationship between the use of features that afford interactivity, agency, and modality and behavioral change. Theoretical and methodological implications are discussed.
先前的研究初步发现，互动性、自主性和模态的可供性可以帮助增加身体活动（PA）。然而，这些研究的横截面性质仅提供了行为的快照，而不能评估技术可供性对 PA 行为的影响。在这项研究中，我们弥补了这一空白，并测试了技术的互动性、自主性和模态选择的功能是否会随着时间的推移与 PA 的增加相关。在动机技术模型（MTM）的指导下，我们从 BodySpace 应用程序（一款社交举重智能手机应用程序）中提取了 784 个用户资料，分别在基线和 70 天后进行了分析，并建立了互动性、自主性和模态功能的使用与行为变化之间的关系。讨论了理论和方法学的意义。
