The Relationship Between Procrastination and Sleep Quality:The Mediating Effects of Rumination and Depression and Gender Differences

目的:探讨反刍思维、抑郁情绪在拖延和睡眠质量之间的中介作用及其性别差异。方法:采用Aitken拖延问卷(API)、反刍思维量表、抑郁自评量表(PHQ-9)和匹兹堡睡眠质量指数对北京市5704名学生进行问卷调查。结果:(1)拖延与睡眠问题、反刍思维、抑郁情绪均显著正相关;(2)拖延对睡眠问题有显著的正向预测作用,反刍思维、抑郁情绪在其中链式中介作用显著;(3)拖延对抑郁情绪的影响、反刍思维对抑郁情绪的影响存在性别差异,反刍思维和抑郁情绪在拖延和睡眠质量之间的链式中介作用存在性别差异。结论:拖延对睡眠质量有显著直接影响,并通过反刍思维和抑郁情绪起到间接作用,这一链式中介作用存在性别差异。

Objective:The current study aimed at exploring the mediating effects of rumination and depression in the relationship between procrastination and sleep quality as well as their gender differences.Methods:A sample of 5,704 students was recruited,and the Aitken Procrastination Inventory(API),Ruminative Responses Scale(RRS),Patient Health Questionnaire-9(PHQ-9)and Pittsburgh Sleep Quality Index(PSQI)were used.Results:(1)The correlations among sleep quality,rumination,depression,and procrastination were positive and statistically significant;(2)Procrastination showed a significantly positive effect on college students'sleep problem,and the chain mediating effect of rumination and depression in the relationship between procrastination and sleep quality was significant;(3)There were gender differences in the effects of procrastination and rumination on depression,as well as in the chain mediating effect of rumination and depression in the relationship between procrastination and sleep quality.Conclusion:Procrastination showed not only a direct effect on sleep quality,but also indirect effects via rumination and depression.A gender gap was also found in the chain mediating effect of rumination and depression.
