社交媒体促进青少年体育行为的影响机制——基于混合方法的研究

Influential Mechanism of Social Media in Promoting Adolescents'Sports Behavior——A Study Based on Mixed Method

目的:探讨社交媒体对青少年体育行为的影响机制,为促进青少年在新媒体环境下的体育行为生成与保持提供参考。方法:采用混合方法揭示社交媒体(社交分享和社交竞争)、社交自我效能感、自我呈现与青少年体育行为的关系,以及社交媒体影响青少年体育行为的机制。结果:社交分享和社交竞争对青少年体育行为具有积极的促进作用,社交自我效能感在社交分享、社交竞争与青少年体育行为之间起中介作用,自我呈现在社交分享、社交竞争与青少年体育行为之间未发挥正向调节作用。社交媒体通过社交互动和运动打卡影响青少年的体育态度和认知,从而促进青少年体育行为。结论:社交媒体不仅塑造用户个人身体认知,还影响用户对传播对象的身体认知以及对体育行为的态度,其通过具身媒介、身体规训、技术工具和信息反馈等开放式闭环作用促进青少年体育行为的发展。

Objective:To explore the influential mechanism of social media in promoting adolescents'sports behavior,and to provide a reference for promoting the generation and maintenance of adolescents'sports behavior in the new media environment.Methods:A mixed-method approach was used to reveal the relationship between social media(social sharing and social competition),social self-efficacy,self-presentation and adolescents'sports behaviors,and the influential mechanism of social media on adolescents'sports behaviors.Results:Social sharing and social competition have positive facilitative effects on adolescents'sports behavior.Social self-efficacy plays a mediating role among social sharing,social competition and adolescents'sports behavior,while self-presentation does not play a positive moderating role between social sharing,social competition and adolescents'sports behavior.Social media promotes adolescents'sports behavior by influencing adolescents'sports attitudes and perceptions through social interactions and sports punch cards.Conclusion:Social media not only shape users'personal body perceptions,but also influence users'body perceptions of communication targets as well as their attitudes toward sports behavior.Social media facilitates the development of adolescents'sports behavior through the open-ended closed-loop role of embodied media,physical discipline,technological tools,and information feedback.
