新型冠状病毒肺炎疫情下武汉市居民压力知觉与睡眠质量的关系:心理弹性的调节作用

The relationship between perceived stress and sleep quality of Wuhan residents during COVID-19 outbreak: psychological resilience as a moderator

目的了解面临新型冠状病毒肺炎突发疫情时武汉市居民睡眠质量状况,探讨心理弹性、压力知觉与睡眠质量之间的关系。方法 2020年2月1―5日利用微信App,收集到1 178名武汉市居民填写的失眠严重指数量表、压力知觉量表和心理弹性量表数据,运用分层回归方程模型分析调节作用。结果被调查居民睡眠质量总分中位数为3.11(0.93,7.04)分,24.62%的被调查居民存在睡眠质量问题。在婚姻状况、压力知觉、心理弹性方面,居民睡眠质量得分差异有统计学意义(均有P<0.001)。睡眠质量总分与压力知觉呈正相关(r=0.378,P<0.001),与心理弹性呈负相关(r=-0.299,P<0.001),心理弹性与压力知觉总分呈负相关(r=-0.563,P<0.001)。心理弹性在压力知觉和睡眠质量间起调节作用(β=-0.249,P=0.011)。结论突发新型冠状病毒肺炎疫情下压力知觉直接影响居民睡眠质量,心理弹性能减缓压力知觉的负面影响起到保护作用。

Objective To examine the situation of sleep quality and to explore the moderate effect of psychological resilience between perceived stress and sleep quality of Wuhan residents during COVID-19 outbreak. Methods From February 1 to 5 in 2020, a WeChat survey was established among 1 178 Wuhan residents aged more than 18 years with the insomnia severity index(ISI), perceived stress scale, and 10-item connor-davidson resilience scale. Moderating effect was analyzed with hierarchical regression analysis. Results The median of ISI scores was 3.11(0.93, 7.04) among the residents, and 24.62% of the interviewee were suffered from poor sleep quality. There were significant differences between ISI scores and marital status, and perceived stress, and psychological resilience(all P<0.001). ISI scores were positively correlated with perceived stress(r=0.378, P<0.001), and negatively correlated with psychological resilience(r =-0.299, P<0.001). And negative correlation was found between psychological resilience and perceived stress(r =-0.563, P<0.001). Psychological resilience moderated the relationship between perceived stress and sleep quality(β=-0.249, P=0.001). Conclusion The psychological resilience could buffer negative effect of perceived stress on sleep quality, and is a crucial protective factor for improving sleep quality among residents during the COVID-19 outbreak.
