移动的应用程序是管理健康干预和改变关键生活方式领域（如体育活动）用户行为的有效工具，但健身应用程序用户的流失率很高。为了了解如何提高用户保留率，本研究借鉴了技术接受模型（TAM），并探讨了运动自我效能的作用，除了原来的TAM结构，即感知有用性，感知易用性，感知享受，在预测当前用户的意图，继续使用的应用程序。此外，本研究从人与技术互动的角度扩展了TAM，阐明了健身移动的应用程序提供的特定功能方面的感知有用性的前因。样本来自一个大型的在线中国受试者库，通过调查（N = 449）来检验假设。研究结果表明，教学提供、自我监控、自我调节和目标达成等四项技术功能通过感知有用性对持续意愿产生间接影响，且这种间接影响受到运动自我效能的调节，运动自我效能越低，感知有用性与持续意愿之间的关联越强。
Mobile apps are effective tools for administering health interventions and changing user behaviors in key lifestyle areas, such as physical activity, but the attrition rates of fitness app users are high. To understand how to increase user retention rates, the present study draws from the Technology Acceptance Model (TAM) and investigates the role of exercise self-efficacy, in addition to the original TAM constructs, namely, perceived usefulness, perceived ease of use, and perceived enjoyment, in predicting current users' intention to continue using the apps. Moreover, this study extends TAM from a human-technology interaction perspective by elucidating the antecedents of perceived usefulness in terms of specific functions provided by fitness mobile apps. Samples were drawn from a large online Chinese subject pool to test the hypotheses via a survey (N = 449). The results showed that four technological functions-instruction provision, self-monitoring, self-regulation, and goal attainment-had an indirect effect on continuance intention through perceived usefulness, and this indirect effect was moderated by exercise self-efficacy such that the association between perceived usefulness and continuance intention was stronger for those with low exercise self-efficacy.
