压力对睡眠质量的影响及机制研究：应对弹性的调节作用

The Effect of Stress on Sleep Quality and Its Mechanism: The Modulatory Role of Coping Resilience

摘要: 目的：探讨个体压力与睡眠质量之间的关系，以及应对弹性的调节作用。方法：2024年5月采用匹兹堡睡眠质量指数量表(Pittsburgh Sleep Quality Index, PSQI)、中文版压力知觉量表(Chinese Perceived Stress Scale, CPSS)、应对弹性量表(Coping Flexibility Questionnaire, CFQ)对436名被试用方便抽样法进行线上的问卷调查，使用共同方法偏差检验，并对睡眠质量和压力知觉、应对弹性之间的相关关系进行检验和描述统计；使用process 4.1进行Model 1调节效应的分析，检验应对弹性在压力知觉与睡眠质量之间的调节作用。结果：(1) 有19.50%的被试存在睡眠质量问题；(2) 睡眠质量与压力知觉呈显著正相关。(3) 应对弹性在压力知觉和睡眠质量之间有一定的调节作用，能有效缓解压力知觉对睡眠质量的消极影响。结论：部分民众存在睡眠质量问题，当个体感知到的压力越大，其睡眠越差；而个体应对压力事件的灵活程度在压力对睡眠质量之间起着缓冲作用，可以有效减少压力对睡眠的影响。

Abstract: Objective: To explore the relationship between individual stress and sleep quality, as well as the moderating effect of coping resilience. Methods: In May 2024, a convenience sampling method was used to conduct an online questionnaire survey of 436 participants using the Pittsburgh Sleep Quality Index (PSQI), the Chinese Perceived Stress Scale (CPSS), and the coping resilience Questionnaire (CFQ). Common method bias was tested, and the correlation and descriptive statistics between sleep quality, perceived stress, and coping flexibility were examined. Model 1 of process 4.1 was used to analyze the moderating effect of coping flexibility on the relationship between perceived stress and sleep quality. Results: (1) 19.50% of the subjects had sleep quality problems; (2) Sleep quality was significantly positively correlated with perceived stress. (3) Coping resilience has a certain regulatory effect between perceived stress and sleep quality, and can effectively alleviate the negative impact of perceived stress on sleep quality. Conclusion: Some individuals have sleep quality problems, and the more an individual perceives stress, the worse their sleep will be. Meanwhile, the flexibility with which individuals cope with stressful events serves as a buffer between stress and sleep quality, effectively reducing the impact of stress on sleep.
