为揭示数字化时代大学新生的心理适应机制，探讨体像自我差异与社交媒体使用动机的关系，以及社交焦虑在二者之间的作用，采用身体意像评估量表、社交焦虑量表以及社交媒体使用动机量表对1350名大一新生开展调查。结果显示：体像自我差异与社交焦虑显著正向联系，社交焦虑与社交媒体使用动机显著正向联系；社交焦虑在体像自我差异与社交媒体使用动机之间中介效应显著；相比男生，社交焦虑的中介效应在女生群体中显著。研究整合了自我差异理论和网络社会补偿理论，为高校构建促进新生人际适应的线上支持系统提供理论和实践参考。

To reveal the psychological adaptation mechanisms of college freshmen in the digital age, this study explored the relationship between body image self-discrepancy and social media use motivations, as well as the role of social anxiety between them. A survey was conducted among 1,350 first-year college students using the Body Image Assessment Scale, the Social Anxiety Scale, and the Social Media Use Motivation Scale. The results indicated that there is a significant positive correlation between body image self-discrepancy and social anxiety, as well as a significant positive correlation between social anxiety and the social media use motivation. Meanwhile, social anxiety plays a significant mediating role between body image self-discrepancy and motivations for social media use. Moreover, the mediating effect of social anxiety is more pronounced in the female group compared to the male group. Integrating Self-Discrepancy Theory and the Online Social Compensation Theory, this research provided theoretical and practical references for universities to build online support systems that promote freshmen’s interpersonal adaptation.
