The COVID-19 pandemic has led to increased depressive symptoms and diminished sleep quality among nurses. This study explores the relationships among social support, sleep quality, and depressive symptoms among Chinese nurses during the COVID-19 outbreak, with a focus on the mediating role of sleep quality.
A cross-sectional study involving 2140 nurses was conducted from August to September 2022. The participants completed the Social Support Rating Scale, the Hospital Anxiety and Depression Scale, and the Pittsburgh Sleep Quality Index. The data were analyzed via serial multiple mediation analysis with the PROCESS macro in SPSS.
Depressive symptoms affected an estimated 40.4% of the participants, with 69.2% reporting poor sleep quality. The present study revealed a significant negative correlation between social support and sleep quality and depressive symptoms (r = -0.229, p < 0.001; r = -0.322, p < 0.001, respectively). Furthermore, a substantial positive correlation was observed between sleep quality and depressive symptoms (r = 0.514, p < 0.001). Additionally, social support had a significant indirect effect on depressive symptoms through sleep quality (standardized effect = -0.0535, 95% CI = [-0.0648, -0.0424]). Sleep quality was found to mediate the relationship between social support and depressive symptoms in all subgroups, with variations based on years of experience, education levels, and hospital type.
Depressive symptoms were inversely associated with social support, which was moderated by sleep quality. Interventions targeting social support provision and sleep quality promotion are suggested for managing depressive symptoms among nurses during the COVID-19 pandemic.
新冠疫情导致护士群体中抑郁症状增加，睡眠质量下降。本研究探讨了新冠疫情期间中国护士的社会支持、睡眠质量和抑郁症状之间的关系，重点关注睡眠质量的中介作用。
于2022年8月至9月进行了一项横断面研究，共纳入2140名护士。参与者完成了社会支持评定量表、医院焦虑抑郁量表和匹兹堡睡眠质量指数。数据通过SPSS中的PROCESS宏进行系列多重中介分析。
估计有40.4%的参与者出现抑郁症状，69.2%的参与者报告睡眠质量差。本研究显示社会支持与睡眠质量和抑郁症状之间存在显著负相关（r = -0.229，p < 0.001；r = -0.322，p < 0.001）。此外，睡眠质量与抑郁症状之间存在显著正相关（r = 0.514，p < 0.001）。此外，社会支持通过睡眠质量对抑郁症状有显著间接效应（标准化效应 = -0.0535，95% CI = [-0.0648, -0.0424]）。发现睡眠质量在所有亚组中均中介了社会支持与抑郁症状之间的关系，并因工作年限、教育水平和医院类型而异。
抑郁症状与社会支持呈负相关，睡眠质量起调节作用。建议在新冠疫情期间针对护士群体提供社会支持和促进睡眠质量的干预措施，以管理其抑郁症状。
