Abstract：
During the COVID-19 pandemic healthcare workers were repeatedly exposed to traumatic experiences. Facing life-threatening events and repeated exposure to traumatic duty-related situations may cause posttraumatic stress disorder (PTSD). While tonic immobility has been considered a key vulnerability factor for PTSD, little is known about this relationship in the long term. In this study, we aimed to determine whether peritraumatic tonic immobility triggered by COVID-19-related trauma predicts PTSD symptom severity six to twelve months later. We conducted an online longitudinal survey using the PTSD Checklist for the DSM-5 (PCL-5) and the Tonic Immobility Scale to assess PTSD symptoms and the tonic immobility response, respectively. Multivariate regression models revealed a significant association between tonic immobility and PTSD symptoms. Each one-unit increase in the tonic immobility score was associated with a 1.5 % increase in the average PTSD symptom score six to twelve months after the traumatic event that triggered the tonic immobility. Furthermore, participants who showed significant or extreme levels of tonic immobility were 3.5 times or 7.3 times more likely to have a probable PTSD diagnosis, respectively. Hence, peritraumatic tonic immobility seems to have a lasting deleterious effect on mental health. Psychological treatment for health care professionals is urgent, and psychoeducation about the involuntary, biological nature of tonic immobility is essential to reduce suffering.
摘要：
在COVID-19大流行期间，医护人员反复遭受创伤经历。面对危及生命的事件和反复暴露于与任务有关的创伤性情况可能会导致创伤后应激障碍（PTSD）。虽然强直性不动性被认为是创伤后应激障碍的关键脆弱性因素，从长远来看，人们对这种关系知之甚少。在这项研究中,我们的目的是确定由COVID-19相关创伤引发的创伤周围性强直不活动是否能预测6~12个月后PTSD症状的严重程度.我们使用DSM-5（PCL-5）的PTSD清单和Tonic不动量表进行了一项在线纵向调查，以评估PTSD症状和强直性不动反应，分别。多变量回归模型显示，强直性不活动与PTSD症状之间存在显着关联。在引发强直性不动的创伤事件发生后6至12个月，强直性不动评分每增加一个单位，平均PTSD症状评分就会增加1.5％。此外，显示出显著或极端水平的强直性不活动的参与者有可能有PTSD诊断的可能性是3.5倍或7.3倍，分别。因此，围手术期补品不动似乎对心理健康有持久的有害影响。医护人员的心理治疗刻不容缓,关于非自愿的心理教育，补品不动的生物学性质对于减少痛苦至关重要。
