摘　　要：目的探讨社交媒体成瘾与大学生焦虑的关系,以及睡眠拖延和压力知觉在其中的作用。方法2023年9月采用方便抽样法选取15493名大学生,使用社交媒体成瘾量表、睡眠拖延量表、中文版压力知觉量表和广泛性焦虑障碍量表进行调查,运用SPSS 25.0的process宏程序检验睡眠拖延的中介效应和压力知觉的调节效应。结果社交媒体成瘾对大学生焦虑具有正向预测作用(β=0.307,P<0.001)。睡眠拖延在社交媒体成瘾与大学生焦虑之间起部分中介作用,中介效应值为0.06(95%Bootstrap CI=[0.055~0.065]),占总效应的19.54%。压力知觉在睡眠拖延和焦虑之间起调节作用(β=0.094,P<0.001),随着压力知觉水平升高,睡眠拖延与焦虑的正向关联越强。结论社交媒体成瘾可以直接影响大学生焦虑,也可以通过睡眠拖延间接影响,且压力知觉调节该中介模型中睡眠拖延到焦虑的路径。Objective To explore the relationship between social media addiction and anxiety among college students and the role of bedtime procrastination and stress perception.Methods 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.Results 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.Conclusion 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.
