高职生的睡眠质量在负性情绪与自我效能感间的中介作用

Mediating Effects of Sleep Quality between Negative Emotion and Self-efficacy in Vocational College Students

采用抑郁-焦虑-压力量表简体中文版(DASS-21)、匹兹堡睡眠指数量表(PSQI)和一般自我效能感量表(GSES)对575名高职生进行调研,运用二分类Logistic回归分析方法,分析高职生的负性情绪、睡眠质量和自我效能感的关系。结果表明:高职生抑郁检出率为25.6%,焦虑检出率为48.0%,压力检出率为24.5%,睡眠问题检出率为29.7%,自我效能感(24.07±5.25)分,低于国内成人常模(t=-20.826,P<0.001);高职生的抑郁、焦虑、压力正向预测睡眠质量(P<0.05),睡眠质量负向预测自我效能感(P<0.05);抑郁、焦虑、压力通过影响睡眠质量间接影响自我效能感(P<0.01)。可见,高职生的睡眠质量和负性情绪对其自我效能感具有重要影响,睡眠质量在负性情绪与自我效能感之间起部分中介作用。

Depression Anxiety Stress Scales(DASS),Pittsburgh Sleep Quality Index(PSQI)and General Self-Efficacy Scale(GSES)are used to investigate 575 higher vocational college students.The relationships between their negative emotion,sleep quality and self-efficacy were analyzed by binary Logistic regression analysis method.The results show that the detectable rate of depression,anxiety and stress of higher vocational college students was 25.6%,48%,24.5%,respectively.The prevalence of sleeping problems in them was 29.7%and self-efficacy was(24.07±5.25)which was below that of the national adults(t=-20.826,P<0.001).Depression,anxiety and stress had significant positive effects on sleep quality(P<0.05);Sleep quality negatively predicted self-efficacy(P<0.05);Depression,anxiety and stress indirectly influenced the self-efficacy through the sleep quality(P<0.01).A conclusion can be drawn that negative sleep quality and emotion had impacts on the self-efficacy in vocational college students,and the sleep quality played a partly mediating role between negative emotion and self-efficacy in vocational college students.
