Outline
To explore the relationship between social media addiction and anxiety among college students and the role of bedtime procrastination and stress perception.
A total of 15493 college students were selected by convenience sampling in September 2023 with using the Bergen Social Networking Addiction Scale, the Bedtime Procrastination Scale, the Chinese Perceived Stress Scales and the Generalized Anxiety Disorder 7-item Scale. SPSS25.0 macro program PROCESS was used to analyze the mediating effect of bedtime procrastination and the moderating effect of stress perception.
The social media addiction was positively predicted college students’ anxiety (β=0.307, P<0.001). Bedtime procrastination partially mediated the relationship between social media addiction and anxiety in the college students. The mediation effect value was 0.060 (95% Bootstrap CI=[0.055-0.065]), the mediating effect accounted for 19.54% of the total. Stress perception moderated the relationship between bedtime procrastination and anxiety (β=0.094, P<0.001). As the level of perceived stress increased, the positive association between bedtime procrastination and anxiety became stronger.
Social media addiction can directly affect anxiety in the college students, or indirectly affect it through bedtime procrastination, and perceived stress moderates the path from bedtime procrastination to anxiety in the mediation model.
