Nurses are at high risk for depression and anxiety symptoms after the outbreak of the COVID-19 pandemic. We aimed to assess the network structure of anxiety and depression symptoms among Chinese nurses in the late stage of this pandemic.
A total of 6,183 nurses were recruited across China from Oct 2020 to Apr 2021 through snowball sampling. We used Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder scale-7 (GAD-7) to assess depression and anxiety, respectively. We used the Ising model to estimate the network. The index "expected influence" and "bridge expected influence" were applied to determine the central symptoms and bridge symptoms of the anxiety-depression network. We tested the stability and accuracy of the network the case-dropping procedure and non-parametric bootstrapping procedure.
The network had excellent stability and accuracy. Central symptoms included "restlessness", "trouble relaxing", "sad mood", and "uncontrollable worry". "Restlessness", "nervous", and "suicidal thoughts" served as bridge symptoms.
Restlessness emerged as the strongest central and bridge symptom in the anxiety-depression network of nurses. Intervention on depression and anxiety symptoms in nurses should prioritize this symptom.
新冠疫情爆发后，护士出现抑郁和焦虑症状的风险较高。本研究旨在评估新冠疫情后期中国护士的焦虑和抑郁症状的网络结构。
2020 年 10 月至 2021 年 4 月，通过滚雪球抽样的方式在中国招募了 6183 名护士。我们使用患者健康问卷-9（PHQ-9）和广泛性焦虑障碍量表-7（GAD-7）分别评估抑郁和焦虑。我们使用伊辛模型来估计网络。使用“预期影响”和“桥接预期影响”指标来确定焦虑-抑郁网络的中心症状和桥接症状。我们通过病例删除程序和非参数 bootstrap 程序测试了网络的稳定性和准确性。
该网络具有很好的稳定性和准确性。中心症状包括“不安”、“难以放松”、“悲伤情绪”和“无法控制的担忧”。“不安”、“紧张”和“自杀念头”是桥接症状。
在护士的焦虑-抑郁网络中，不安是最强的中心和桥接症状。干预护士的抑郁和焦虑症状应优先考虑这一症状。
