BackgroundThis study aimed to report the prevalence of COVID-19 over-concern and its associated factors after the relaxation of the health-protective measures in China.MethodsA team of seven experts in psychiatry and psychology specializing in COVID-19 mental health research from China, Hong Kong, and overseas reached a consensus on the diagnostic criteria for COVID-19 over-concern. Individuals had to meet at least five of the following criteria: (1) at least five physical symptoms; (2) stocking up at least five items related to protecting oneself during the COVID-19 pandemic; (3) obsessive-compulsive symptoms related to the COVID-19 pandemic; (4) illness anxiety related to the COVID-19 pandemic; (5) post-traumatic stress symptoms; (6) depression; (7) anxiety; (8) stress and (9) insomnia. An online survey using snowball sampling collected data on demographics, medical history, views on COVID-19 policies, and symptoms of COVID-19 over-concern. Multivariate linear regression was performed using significant variables from the previous regressions as independent variables against the presence of COVID-19 over-concern as the dependent variable. Breush-Pagan test was used to assess each regression model for heteroskedasticity of residuals.Results1,332 respondents from 31 regions in China participated in the study for 2 weeks from December 25 to 27, 2022, after major changes in the zero-COVID policy. After canceling measures associated with the dynamic zero-COVID policy, 21.2% of respondents fulfilled the diagnostic criteria for COVID-19 over-concern. Factors significantly associated with COVID-19 over-concern were poor self-rated health status (β = 0.07, p

本研究旨在报告中国在放宽健康防护措施后，COVID-19过度关注现象的流行情况及其相关因素。方法上，由来自中国、香港及海外七位专注于COVID-19心理健康研究的心理学与精神病学专家团队，对COVID-19过度关注的诊断标准达成共识。个体需满足以下至少五项标准：（1）至少五种身体症状；（2）储备至少五种与COVID-19疫情期间自我保护相关的物品；（3）与COVID-19疫情相关的强迫症状；（4）与COVID-19疫情相关的疾病焦虑；（5）创伤后应激症状；（6）抑郁；（7）焦虑；（8）压力；（9）失眠。通过在线问卷调查，采用滚雪球抽样方法收集了关于人口统计学、病史、对COVID-19政策看法以及COVID-19过度关注症状的数据。采用多变量线性回归，以先前回归分析中显著变量作为自变量，以COVID-19过度关注的程度作为因变量进行回归分析。使用Breush-Pagan检验评估每个回归模型的残差异方差性。结果：2022年12月25日至27日，在零COVID政策发生重大变化后，来自中国31个地区的1,332名受访者参与了为期两周的研究。在取消与动态零COVID政策相关的措施后，21.2%的受访者符合COVID-19过度关注的诊断标准。与COVID-19过度关注显著相关的因素包括自我评价健康状况不佳（β=0.07，p<0.05）等。
