The 2019 coronavirus disease (COVID-19) has spread worldwide, and its associated stressors have resulted in decreased sleep quality among front-line workers. However, in China, the general public displayed more psychological problems than the front-line workers during the pandemic. Therefore, we investigated the influence of perceived stress on the sleep quality of the non-diseased general public and developed a moderated mediation model to explain said relationship.
Questionnaire-based surveys were conducted online from February 18-25, 2020 with 1630 Chinese participants (aged 18-68 years).
Around one-third (36.38%) of participants were poor sleepers during the COVID-19 pandemic. Moreover, higher perceived stress was significantly associated with higher anxiety levels, which, in turn, was associated with lower sleep quality. Self-esteem moderated the indirect effect of perceived stress on sleep quality through its moderation of the effect of perceived stress on anxiety. This indicated that the mediation effect of anxiety was stronger in those with low levels of self-esteem than in those with high levels of self-esteem.
These findings suggest that both the sleep quality and perceived stress levels of the non-diseased general public required attention during the COVID-19 pandemic. Our findings also identify personality characteristics related to better sleep quality, demonstrating the important role of self-esteem in environmental adaptation.
2019 年冠状病毒病（COVID-19）已在全球范围内传播，其相关压力源导致一线工作者的睡眠质量下降。然而，在中国，大流行期间公众的心理问题比一线工人更多。因此，我们调查了感知压力对未患病普通公众睡眠质量的影响，并建立了一个调节中介模型来解释这种关系。
我们于 2020 年 2 月 18 日至 25 日在线进行了基于问卷调查的研究，共有 1630 名中国参与者（年龄在 18-68 岁之间）。
大约三分之一（36.38%）的参与者在 COVID-19 大流行期间睡眠质量较差。此外，较高的感知压力与较高的焦虑水平显著相关，而较高的焦虑水平又与较低的睡眠质量相关。自尊调节了感知压力对焦虑的影响，从而调节了感知压力对睡眠质量的间接影响。这表明，在自尊心较低的人群中，感知压力对焦虑的影响的中介效应要强于自尊心较高的人群。
这些发现表明，在 COVID-19 大流行期间，未患病普通公众的睡眠质量和感知压力水平都需要引起关注。我们的研究结果还确定了与更好的睡眠质量相关的人格特征，这表明自尊在环境适应中起着重要作用。
