This study explores the relationship mechanisms, particularly the mediating roles of self-efficacy and coping styles.MethodsData were collected from 615 college students using questionnaires. Structural equation modeling was employed to analyze the data and investigate both the direct and indirect effects of social media addiction on psychological anxiety through the lens of self-efficacy and coping styles.ResultsThe results indicated a significant positive correlation between social media addiction and psychological anxiety. Specifically, social media addiction was found to not only directly increase psychological anxiety but also indirectly affect it through two pathways: (1) by reducing self-efficacy, which in turn heightened psychological anxiety, and (2) by influencing coping styles, wherein negative coping styles were positively related to psychological anxiety. Moreover, a chain mediation effect was observed where social media addiction led to decreased self-efficacy, subsequently shifting coping styles and ultimately exacerbating psychological anxiety.Discussion and conclusionsThese findings highlight the critical roles of self-efficacy and coping styles in the relationship between social media addiction and psychological anxiety among college students. They provide valuable insights for developing targeted interventions to mitigate the adverse effects of social media addiction on mental health, emphasizing the importance of enhancing self-efficacy and promoting positive coping strategies. By addressing these factors, universities can better support students in maintaining healthy social media habits and reducing psychological anxiety.
