压力知觉对大学生心理健康的影响——睡眠质量的中介作用

Influence of perceived stress on the mental health of college students:The mediating role of sleep quality

探究大学生睡眠质量在压力知觉与心理健康关系间的中介作用.采用压力知觉量表、匹兹堡睡眠质量指数量表和症状自评量表对苏州大学、苏州城市学院、苏州大学应用技术学院、苏州科技大学352名在校大学生进行在线问卷调查.结果表明:(1)不同性别和不同生源地的大学生在压力知觉、睡眠质量及心理健康上并无显著差异;(2)大学生压力知觉、睡眠质量、心理健康两两之间呈显著正相关;(3)压力知觉对心理健康的直接效应,以及睡眠质量在压力知觉和心理健康之间的中介效应均显著,直接效应值和中介效应值分别为0.16、0.13.可见,大学生压力知觉可以直接预测其心理健康,也可以通过睡眠质量的中介作用间接影响其心理健康.建议高校采取更加科学有效的措施来提升学生心理健康水平,具体措施包括加强心理健康教育,提升个体心理韧性,以及提高学生体育锻炼积极性,培养规律作息习惯.

To explore the mediating role of sleep quality in the relationship between stress perception and mental health of college students,an online questionnaire survey was conducted on 352college students from Soochow University,Suzhou City University,Applied Technology College of Soochow University,and Suzhou University of Science and Technology by using Perceived Stress Scale,Pittsburgh Sleep Quality Index,and Symptom Checklist 90.The results showed that:(1)There were no significant differences in stress perception,sleep quality and mental health among college students of different genders and different origins;(2)There was a significant positive correlation between stress perception,sleep quality and mental health of college students.(3)Both of the direct effect of stress perception on mental health and the mediating effect of sleep quality on the relationship between stress perception and mental health were significant,with direct and mediating effect sizes of 0.16and 0.13 respectively.It can be seen that the stress perception of college students can directly predict their mental health,and can also indirectly affect their mental health through the mediating effect of sleep quality.It is suggested that colleges and universities should take more scientific and effective measures to improve students′mental health,including strengthening mental health education,enhancing individual psychological resilience,improving students′enthusiasm for physical exercise,and cultivating regular work and rest habits.
