摘要目的 探讨大学生睡眠质量、网络成瘾在负性生活事件与心理健康间的多重中介效应.方法 运用横断调查方法,采用青少年生活事件量表、匹兹堡睡眠质量指数量表、中文网络成瘾量表和一般健康问卷对733名大学生进行调查,采用SPSS进行数据分析,并用Bootstrap法进行多重中介效应检验.结果 负性生活事件、睡眠质量、网络成瘾与心理健康的得分分别为46.0(33.0,66.5)分、5.0(3.0,7.0)分、44.0(37.0,50.0)分和5.0(2.0,9.0)分,并且两两之间均呈正相关(r=0.39～0.55,均P＜0.01);负性生活事件对心理健康的直接效应显著,效应值为0.013,效应量为17.97％,睡眠质量和网络成瘾在负性生活事件与心理健康间的简单中介作用显著,效应值分别为0.047、0.009,效应量分别为64.85％、11.94％,且睡眠质量和网络成瘾的链式中介作用也显著,效应值为0.004,效果量为5.24％.结论 负性生活事件不仅直接影响大学生的心理健康状况,还可以通过睡眠质量-网络成瘾的多重中介作用间接影响大学生的心理健康.

abstractsObjective To explore the multiple mediating effect of sleep quality and internet addiction between negative life events and mental health among college students.Methods A cross-sectional study was used to investigate 733 college students with adolescent self-rating life events checklist,Pittsburgh sleep quality index,the general health questionnaire and internet addiction scale for Chinese revision.SPSS and Bootstrap method were used to test the hypothetical model.Results The scores of Negative life events,sleep quality,interaet addiction and mental health were 46.0 (33.0,66.5),5.0 (3.0,7.0),44.0 (37.0,50.0) and 5.0(2.0,9.0) respectively,and they were positively correlated with each other (r=0.39-0.55,P＜0.01).Negative life events had a direct effect on mental health.The effect value was 0.013,and the effect size was 17.97％.The simple mediating effects of sleep quality and internet addiction between negative life events and mental health were significant.The effect values were 0.047 and 0.009,and the effect sizes were 64.85％ and 11.94％,respectively.The chain mediating effect of sleep quality-internet addiction was also significant,and the effect value was 0.004 and the effect size was 5.24％.Conclusion Negative life events not only directly affect mental health in college students,but also indirectly affect their mental health through the multiple mediating effects of sleep quality and internet addiction.
