社会支持对大学生睡眠质量的影响:有调节的中介效应

Effect of social support on sleep quality of college students:moderated mediating effect

目的探讨大学生社会支持对睡眠质量影响的内部机制,为改善大学生的睡眠质量提供理论依据。方法采用领悟社会支持量表(Perceived Social Support Scale,PSSS)、Connor-Davidson弹性量表简化版(Connor-Davidson Elasticity Scale Simplified,CD-RISC10)、广泛性焦虑量表(Generalized Anxiety Scale,GAD-7)、匹兹堡睡眠质量指数量表(Pittsburgh Sleep Quality Index Scale,PSQI)对山东省1036名大学生进行调查。结果社会支持对大学生睡眠质量有显著的正向预测作用(β=-0.19,P<0.001),大学生的心理弹性在社会支持与睡眠质量中起部分中介作用,中介效应占总效应的57.89%,社会支持与焦虑情绪的交互项对心理弹性的预测作用显著(t=-4.72,P<0.001),焦虑情绪能够调节社会支持对睡眠质量的作用(t=2.70,P<0.01)。结论社会支持对大学生的睡眠质量有提升作用,心理弹性和焦虑情绪在大学生社会支持与睡眠质量的关系中分别存在中介和调节效应。

Objective To explore the internal mechanism of effect of social support on sleep quality among college students so as to provide a theoretical basis for improving college students’ sleep quality. Methods The Perceived Social Support Scale(PSSS), simplified version of Connor-Davidson Resilience Scale(CD-RISC10), Generalized Anxiety Disorder Scale(GAD-7) and Pittsburgh Sleep Quality Index Scale(PSQI) were used to survey 1,036 college students in Shandong Province. Results Social support had a significant and positive predictive effect on sleep quality of the college students(β=-0.19, P<0.001). The college students’ psychological resilience played a partial mediating role in social support and sleep quality, and the mediating effect accounted for 57.89% of the total effect. The interaction between social support and anxiety had a significant effect on the prediction of mental resilience(t=-4.72, P<0.001). Anxiety could regulate the effect of social support on sleep quality(t=2.70, P<0.01). Conclusion Social support has an effect on improving sleep quality of the college students. Psychological resilience and anxiety have mediating and regulating effects on the relationship between the college students’ social support and sleep quality, respectively.
