The long-term health consequences of the COVID-19 pandemic on health care workers (HCWs) are largely unclear. The purpose of the present study was to investigate the development of posttraumatic stress disorder (PTSD) in HCWs in a longitudinal manner. Additionally, we further explored the role of risk perception in the evolution of PTSD over time based on a one-year follow-up study. HCWs were recruited from hospitals in Guangdong, China. Demographic information, the PTSD checklist for DSM-5 (PCL-5) and the risk perception questionnaire were obtained online at two different time points: May to June 2020 (T1), with 317 eligible responses, and June 2021 (T2), with 403 eligible responses. Seventy-four HCWs participated in the survey at both T1 and T2. The results revealed that (1) the PTSD prevalence rate in the HCWs (cut-off = 33) increased from 10.73% at T1 to 20.84% at T2, and the HCWs reported significantly higher PTSD scores at T2 than at T1 (p < 0.001); (2) risk perception was positively correlated with PTSD (p < 0.001); and (3) PTSD at T1 could significantly positively predict PTSD at T2 (β = 2.812, p < 0.01), and this longitudinal effect of PTSD at T1 on PTSD at T2 was mediated by risk perception at T2 (coefficient = 0.154, 95% CI = 0.023 to 0.297). Our data provide a snapshot of the worsening of HCWs' PTSD along with the repeated pandemic outbreaks and highlight the important role of risk perception in the development of PTSD symptoms in HCWs over time.
COVID-19 大流行对医护人员（HCWs）的长期健康后果在很大程度上尚不清楚。本研究的目的是从纵向角度研究 HCWs 创伤后应激障碍（PTSD）的发展。此外，我们还根据为期一年的随访研究，进一步探讨了风险感知在 PTSD 随时间演变中的作用。HCWs 是从中国广东的医院招募的。在两个不同的时间点（T1：2020 年 5 月至 6 月，有 317 份合格的回应；T2：2021 年 6 月，有 403 份合格的回应）通过在线收集人口统计学信息、DSM-5 创伤后应激障碍检查表（PCL-5）和风险感知问卷。有 74 名 HCWs 在 T1 和 T2 都参与了调查。结果显示：（1）T1 时 HCWs 的 PTSD 患病率（截点=33）从 10.73%增加到 T2 时的 20.84%，T2 时 HCWs 的 PTSD 评分明显高于 T1（p<0.001）；（2）风险感知与 PTSD 呈正相关（p<0.001）；（3）T1 时的 PTSD 可以显著正向预测 T2 时的 PTSD（β=2.812，p<0.01），T1 时 PTSD 对 T2 时 PTSD 的纵向影响是通过 T2 时的风险感知来介导的（系数=0.154，95%置信区间=0.023 至 0.297）。我们的数据提供了 HCWs 的 PTSD 随着疫情的反复爆发而恶化的快照，并强调了风险感知在 HCWs 中 PTSD 症状随时间发展中的重要作用。
