运动健身应用程序使用对个体锻炼行为的影响——锻炼自我效能感的中介效应和社会支持的调节效应

Can Fitness App Use Promote Exercise Behavior? ——Based on the Mediating Effect of Exercise Self-Efficacy and the Moderating Effect of Social Support

为探讨运动健身应用程序(App)使用与用户锻炼行为的关系及其作用机制,在锻炼行为生态学模型的视角下,构建了一个有调节的中介模型。对558名18岁以上的运动健身App用户进行了问卷调查,结果显示:(1)运动健身App使用对用户的锻炼行为有显著正向影响;(2)锻炼自我效能感在运动健身App使用与锻炼行为的关系中发挥了中介作用;(3)朋友支持调节了运动健身APP用户锻炼自我效能感和锻炼行为的关系(中介效应的后半路径),即用户感知到的朋友支持越高,其锻炼自我效能感对锻炼行为的正向影响越强。研究结果为运动健身App与锻炼行为之间的积极联结提供了新的证据,对利用新的媒介技术推动全民健身和健康促进具有一定启示意义。

In order to give an interpretation for the relationship and complex mechanism between fitness app use and exercise behavior,a moderated mediation model was constructed from the perspective of the ecological model of physical activity.A total of 558 fitness app users over the age of 18 in China participated in this study.The results show that:(1)Fitness app significantly and positively influenced exercise behaviors.(2)Exercise self-efficacy cognition partially mediated this relation.(3)This mediating effect was moderated by friends support.The findings not only provide new evidence for the connection between fitness app and exercise behavior,but also can help to promote national fitness and healthy promotion.
