医学生睡眠在心理压力与情绪障碍间的中介效应与调节效应分析

Mediating and Moderating Effects of Sleeping on Psychological Stresses and Emotional Disorders of Medical Students

目的:探讨医学生睡眠在心理压力与情绪障碍间的中介效应与调节效应。方法:以自制调查表、CPSS量表、PSQ量表、SDS量表、SAS量表对520名医学生进行调查。结果:睡眠在压力对焦虑、抑郁的中介效应分别占总效应的比例为43.33%和43.40%,睡眠指数和压力中心化后的交互项分别对SAS标准分、SDS标准分均无统计学意义(P>0.05)。结论:医学生睡眠好坏不仅能预测他们是否会有情绪障碍,而且在压力对情绪障碍的影响中有部分中介作用,但没有调节作用。

This paper explores the mediating and moderating effects of sleeping between psychological stresses and emotional disorders of medical students. 520 medical students are investigated by using self-made questionnaires,Chinese Perceived Stress Scale(CPSS),Pittsburgh Sleep Quality Index(PSQI),Self-rating Depression Scale(SDS) and Self-rating Anxiety Scale(SAS). The results show that the mediating effects of sleeping on anxiety and depression accounted for the proportion of total effects are respectively 43.33% and 43.40%. There are no significant differences in SAS standard score and SDS standard score of interaction between sleep index and stress centralization,which means that sleep quality of medical students can directly predict whether they will have emotional disorders such as anxiety and depression,and stresses have certain mediating effects on anxiety and depression but have no moderating effects.
