睡眠不足对中小学生负性情绪的影响:一个链式中介模型

The Effect of Lack of Sleep on Negative Emotion in Primary and Secondary School Students:A Chain Mediation Model

睡眠不足已然成为当代中小学生普遍面临的问题。为考察社会支持与情绪调节自我效能感在睡眠不足与中小学生负性情绪关系间的中介作用,研究采用睡眠不足问卷、抑郁-焦虑-压力量表简体中文版、社会支持评定量表和情绪调节自我效能感量表,以整群抽样法抽取江苏、安徽1103名中小学生进行调查。结果发现:(1)睡眠不足显著正向预测中小学生负性情绪;(2)社会支持与管理消极情绪自我效能感在睡眠不足与中小学生负性情绪间发挥单独中介作用;表达积极情绪自我效能感的中介作用不显著;(3)社会支持与管理消极情绪自我效能感在睡眠不足与中小学生负性情绪间发挥链式中介作用。可见,睡眠不足对中小学生负性情绪有显著预测作用,社会支持、管理消极情绪自我效能感在其中具有单独及链式中介效应。

Lack of sleep has become a common problem for contemporary primary and secondary school students.To examine the mediating role of social support and emotion regulation self-efficacy in the relationship between sleep loss and negative emotion of primary and secondary school students,we used the Lack of Sleep Questionnaire,the Simplified Chinese version of the Depression-Anxiety-Stress Scale,the Social Support Rating Scale and the Emotion Regulation Self-Efficacy Scale.A whole group sample of 1103 primary and secondary school students in Jiangsu and Anhui were selected for the survey.The results found that:(1)Lack of sleep significantly and positively predicted negative emotion in primary and secondary school students;(2)Social support and perceived self-efficacy in managing negative emotion played a separate mediating role between lack of sleep and negative emotion in primary and secondary school students;the mediating role of self-efficacy for perceived self-efficacy in expressing positive emotion was not significant;(3)Social support and perceived self-efficacy in managing negative emotion played a chain mediating role between lack of sleep and negative emotion in primary and secondary school students.It shows that lack of sleep has a significant effect on the negative emotion of primary and secondary school students.Social support and perceived self-efficacy in managing negative emotion have separate and chained mediating effects.
