The COVID-19 outbreak witnessed in the first months of 2020 has led to unprecedented changes in society's lifestyles. In the current study, we aimed to investigate the effect of this unexpected context on sleep.
During the COVID-19 outbreak, we performed an online survey with individuals formerly recruited for validation of the Spanish version of the sleep questionnaire Satisfaction, Alertness, Timing, Efficiency, and Duration (SATED). In the current survey, we asked the participants to complete the previously answered questionnaires including the Pittsburgh Sleep Quality Index (PSQI), a modified version of the Epworth Sleepiness Scale (ESS), and the SATED questionnaire. We also assessed the mood by the Profile of Mood States (POMS) questionnaire.
The 71 participants were mostly women (75%) with a mean (± SD) age of 40.7 ± 11.9 years. Comparing the previous PSQI score to that during the COVID-19 outbreak, we observed worsening sleep quality (5.45 ± 3.14 to 6.18 ± 3.03 points, p = 0.035). In parallel, there was an increase in the negative mood (p = 0.002). Accordingly, the decrease in sleep quality was substantially correlated with negative mood (p < 0.001). There were no differences in the ESS or SATED.
The COVID-19 outbreak-associated events correlate with decreased sleep quality in association with an increase in negative mood. Considering the importance of sleep for a healthy life, and in particular for immune function, efforts should be made to improve awareness on this matter and to offer psychological assistance to affected individuals.
2020 年初爆发的 COVID-19 疫情导致社会生活方式发生了前所未有的变化。在本研究中，我们旨在探讨这种意外情况对睡眠的影响。
在 COVID-19 疫情期间，我们对以前为验证西班牙语版睡眠问卷满意度、警觉度、时间、效率和持续时间（SATED）而招募的个体进行了在线调查。在本次调查中，我们要求参与者完成以前回答过的问卷，包括匹兹堡睡眠质量指数（PSQI）、嗜睡量表（ESS）的修改版和 SATED 问卷。我们还使用心境状态问卷（POMS）评估了情绪。
71 名参与者主要为女性（75%），平均（± SD）年龄为 40.7 ± 11.9 岁。将之前的 PSQI 评分与 COVID-19 疫情期间的评分进行比较，我们观察到睡眠质量恶化（5.45 ± 3.14 至 6.18 ± 3.03 分，p = 0.035）。与此同时，负面情绪增加（p = 0.002）。因此，睡眠质量的下降与负面情绪呈显著相关（p < 0.001）。ESS 或 SATED 没有差异。
与 COVID-19 疫情相关的事件与睡眠质量下降相关，同时负面情绪增加。考虑到睡眠对健康生活的重要性，特别是对免疫功能的重要性，应努力提高对此事的认识，并为受影响的个体提供心理援助。
