认知情绪调节对健康青年女性睡眠质量的影响:抑郁的中介与遮掩效应

Effects of Cognitive Emotion Regulation on Sleep Quality of Healthy Youth Female:Mediating and Suppressing Effects of Depression

目的:探讨认知情绪调节对健康青年女性睡眠质量的影响,并考察抑郁情绪的中介作用。方法:采用中文版认知情绪调节问卷(CERQ-C)、匹兹堡睡眠质量指数量表(PSQI)和流调中心用抑郁量表(CES-D)对533名健康青年女性进行测量。结果:①27.2%(PSQI≥8)~47.5%(PSQI>5)健康青年女性存在睡眠质量问题。②健康青年女性非适应性策略与抑郁情绪(r=0.465,P<0.001)、睡眠障碍(r=0.342,P<0.001)显著正相关;适应性策略与抑郁情绪显著负相关(r=-0.116,P=0.007),与睡眠障碍相关不显著(r=0.054,P=0.216);抑郁情绪与睡眠障碍显著正相关(r=0.500,P<0.001)。③抑郁情绪在非适应性策略和睡眠质量之间起部分中介作用。④适应性策略与睡眠质量之间存在抑郁情绪的遮掩效应。结论:认知情绪调节对健康青年女性睡眠质量的影响受到抑郁情绪的部分中介和遮掩作用。

Objective:This study investigated the role of depression in mediating the influence of cognitive emotion regulation on sleep quality of healthy youth female.Methods:The Chinese version of Cognitive Emotion Regulation Questionnaire(CERQ-C),the Pittsburgh Sleep Quality Index(PSQI)and the Center for Epidemiological Studies Depression Scale(CES-D)were administrated to 533 healthy youth females.Results:①27.2%(PSQI≥8)~47.5%(PSQI>5)of the healthy youth females had poor sleep quality.②Less adaptive strategy of healthy youth females was significantly positively correlated with depression(r=0.465,P<0.001)and sleep quality(r=0.342,P<0.001);adaptive emotion regulation strategy was significantly negatively correlated with depression(r=-0.116,P=0.007),and was not significantly correlated with sleep quality(r=0.054,P=0.216);depression was significantly positively correlated with sleep quality(r=0.500,P<0.001).③Depression partially mediated the relationship between less adaptive strategy and sleep quality of healthy youth females.④The relationship between adaptive strategy and sleep quality of healthy youth females was suppressed by depression.Conclusion:There were partial mediating and suppressing effects of depression in the relationship between cognitive emotion regulation and sleep quality of healthy youth females.
