就寝拖延在大学生手机依赖与睡眠质量间的中介作用

The mediating effect of bedtime procrastination on mobile phone dependence and sleep quality in college students

目的探讨就寝拖延在大学生手机依赖与睡眠质量之间的中介作用,分析影响大学生睡眠质量的因素及作用机制。方法2022年10月-2023年5月采用便利抽样法,选取1469名石河子在校大学生为调查对象。采用一般资料调查表、就寝拖延量表、青少年手机使用依赖自评问卷及匹兹堡睡眠质量指数量表进行问卷调查,采用Process程序进行就寝拖延的中介作用分析。结果石河子大学生睡眠质量得分为(7.39±2.56)分,55.4%(814/1469)有睡眠质量问题。大学生就寝拖延得分为(26.68±5.78)分,手机依赖得分为(28.60±10.99)分,手机依赖症状报告率为25.70%(377/1469)。就寝拖延得分与睡眠质量得分、手机依赖得分呈正相关(r值分别为0.211、0.524,P<0.001),睡眠质量得分与手机依赖得分呈正相关(r=0.295,P<0.001)。就寝拖延在手机依赖和睡眠质量之间起部分中介作用(SE=0.011,95%CI:0.002~0.018,P<0.05),中介效应占15.1%。结论就寝拖延在大学生手机依赖与睡眠质量间起一定的中介作用,可采取相关措施改善大学生手机依赖,减轻就寝拖延,进而提升睡眠质量。

Objective To explore the mediating role of bedtime procrastination in the relationship between cell phone dependence and sleep quality among college students,and analyze the factors and mechanisms that affect the sleep quality of college students.Methods A convenience sampling method was employed to select 1469 college students at Shihezi University as participants from October 2022 to May 2023.Questionnaires including a general information survey,a bedtime procrastination scale,a self-assessment questionnaire for mobile phone dependence among adolescents,and the Pittsburgh Sleep Quality Index were administered.The Process program was utilized to analyze the mediating effect of bedtime procrastination.Results The sleep quality score of Shihezi University students was(7.39±2.56)points,and 55.4%had sleep quality problems.The score of bedtime delay was(26.68±5.78),the score of mobile phone dependence was(28.60±10.99),and the reporting rate of mobile phone dependence was 25.70%(377/1469).Sleep delay was positively correlated with sleep quality and cell phone dependence(r=0.211,0.524,P<0.001),and sleep quality was positively correlated with cell phone dependence(r=0.295,P<0.001).Bedtime procrastination had a partial mediating effect between phone dependence and sleep quality(SE=0.011,95%CI=0.002-0.018,P<0.05),and the mediating effect accounted for 15.1%.Conclusion Bedtime procrastination plays a certain mediating role between mobile phone dependence and sleep quality among college students.Relevant measures can be taken to improve mobile phone dependence,reduce bedtime procrastination,and thereby enhance sleep quality.
