Trauma and stressor-related disorders among health care workers during COVID-19 pandemic and the role of the gender: A prospective longitudinal survey.

Health-care Workers (HCW) are facing a critical situation caused by Coronavirus Disease 2019 (COVID-19) which could impact on their mental health status. In addition, HCW women have been identified as a group at high-risk of developing psychological distress, although no previous longitudinal studies have explored this issue in a sample of HCW. The main aim of the study was to observe the temporal pattern of the stress reactions among HCW as well as to explore its potential predictors of poor outcome. Moreover, we analyzed possible gender differences in stress reaction responses. One thousand for hundred and thirty-two HCW responded an online survey including sociodemographic, clinical, and psychometric tests in May 2020 while 251 HCW answered in November 2020. Bivariate and multivariate analyses as well as repeated measures analyses were used to achieve the aims of the study. The proportion of HCW who fulfilled Acute Stress Disorder criteria did not change over the follow-up period, although we observed a significant improvement in stress reactions responses among HCW. Proximal factors were the most salient predictors of traumatic reactions. Repeated analyses revealed significant gender differences in acute stress reactions. In addition, women showed significantly greater improvement than men in re-experiencing the traumatic event and hyperarousal dimensions. Monitoring of working conditions as well as emotional reactions in HCW facing major disasters should be carried out to prevent the development of peritraumatic stress reactions. In addition, HCW women are characterized by a different pattern of progression in stress responses
