白内障患者焦虑和抑郁症状的网络分析

Network Analysis of Anxiety and Depressive Symptoms in Cataract Patients

摘要: 本研究采用便利抽样法选取2023年6月至2023年12月在青海省西宁市第一人民医院眼科住院的627名白内障患者为调查对象。采用广泛性焦虑量表(generalized anxiety disorder-7 item scale, GAD-7)、患者健康问卷抑郁症状量表(patients’ health questionnaire depression scale-9 item, PHQ-9)对其进行测量。采用R 4.3.3软件进行描述性统计和网络模型构建，基于网络视角探索白内障患者焦虑–抑郁症状的网络特征，识别核心症状和桥梁症状。结果发现，“感到不安、担心及烦躁”和“无法控制担心”、“做事时提不起劲或没有兴趣”和“感到心情低落、沮丧或绝望”之间存在明显的正则化偏相关。“无法控制担心”和“很难集中精神做事”是网络的核心症状，“感到好像有可怕的事会发生”和“很难集中精神做事”是网络的桥梁症状，以这些因素作为切入点，可降低网络的严重程度，从而有效降低焦虑和抑郁水平。

Abstract: In this study, 627 cataract patients who were hospitalized in the Department of Ophthalmology of the First People’s Hospital of Xining City, Qinghai Province from June 2023 to December 2023 were selected by convenience sampling method. The PHQ-9 and the GAD-7 were used. The R 4.3.3 software was utilized for descriptive statistics and network modeling to explore the network characteristics of anxiety-depression symptoms in cataract patients based on the network perspective and identify central and bridge symptoms. It was found that a significant regularization partial correlation was observed between the symptoms of “nervousness or anxiety” and “uncontrollable worry”, “anhedonia” and “depressed or sad mood”. “Uncontrollable worry” and “concentration difficulties” are central symptoms of the network, and “afraid something will happen” and “concentration difficulties” are bridge symptoms of network. Using these factors as an entry point reduces the severity of the network and thus effectively reduces anxiety and depression levels.
