The Relationship Between Mobile Phone Addiction and Sleep Procrastination in College Students:a Moderated Mediation Model

目的:考察反刍思维在手机成瘾与大学生睡眠拖延间的中介作用,以及性别的调节效应。方法:采用手机成瘾指数量表、反刍思维量表和睡眠拖延量表对527名大学生进行调查。结果:(1)手机成瘾、反刍思维与睡眠拖延的关系两两之间存在正相关;(2)反刍思维在手机成瘾与睡眠拖延之间起部分中介作用,Bootstrap法检验中介效应显著,占总效应的19%;(3)性别调节了中介模型的前半段及后半段路径。因此,与男大学生相比,女大学生手机成瘾通过反刍思维影响睡眠拖延的正向预测作用中更显著。结论:反刍思维在手机成瘾与大学生睡眠拖延的关系中起部分中介作用,性别在其间起调节效应。

Objective:To investigate the mediating role of rumination in mobile phone addiction and sleep procrastination among college students,as well as the moderating effect of gender.Methods:A survey of 527 college students was conducted using the Mobile Phone Addiction Index Scale,Rumination Thinking Scale and Sleep Procrastination Scale.Results:(1)There was a positive correlation between mobile phone addiction,rumination thinking and sleep procrastination,and(2)rumination played a partial mediating role between mobile phone addiction and sleep procrastination,and the Bootstrap method tested a significant mediating effect,accounting for 19%of the total effect.(3)Gender modulates the first and second half paths of the mediation model.Therefore,compared with male college students,the positive predictive effect of mobile phone addiction affecting sleep delay through rumination thinking was more significant in female college students.Conclusion:Rumination plays a mediating role in the relationship between mobile phone addiction and sleep delay among college students,and gender plays a moderating effect in between.
