摘要：Objective: Trauma experience may increase the risk of suicidal thoughts. This study aimed to examine the association of COVID-19-related traumatic events exposure with suicidal thoughts and the mediating roles of sleep disturbances（symptoms of nightmares and insomnia severity） among hospital workers in the most affected area by COVID-19. Methods: A total of 16,220 hospital workers in Wuhan city were recruited via an online platform from May 27,2020,to Jul 31,2020. Participants completed a self-reported questionnaire to evaluate the number of COVID-19 related traumatic events,the frequency of nightmares,insomnia severity,suicidal thoughts,symptoms of depression and anxiety,and demographic characteristics. Bias-corrected bootstrap mediation analysis was used to examine the indirect effects of trauma experience on suicidal thoughts through nightmare frequency and insomnia severity when controlling for psychological status and demographics. Results: Of the sample,13.3% reported having suicidal thoughts in the past month. COVID-19-related traumatic events exposure was associated with insomnia,nightmares,and suicidal thoughts. Pathway analyses showed that the relationship between the number of COVID-19 related traumatic events and suicidal thoughts was fully mediated by the frequency of nightmares,but not insomnia severity,after adjusting for demographic characteristics and symptoms of depression and anxiety. Conclusions: Suicidal thoughts are prevalent among hospital workers from the most affected area by COVID-19. The association of trauma experience with suicidal thoughts was fully mediated by the frequency of nightmares. Identification and intervention of nightmares may have important implications for reducing the risk of suicidal thoughts.
