Exposure to critical events can be seen as a stress factor, the impact of which may depend on the proximity to the stressor (Lai et al., 2020; Motreff et al., 2019), personal risk perception (Vandentorren et al., 2018), gender (Wesemann et al, 2020) or occupation (Wesemann et al., 2020). Vulnerability, resilience and the current mental state are also considered relevant (Neria, Nandy & Galea, 2008), but are rarely recorded before disasters. A large study found incident rates for depression (54%), anxiety (45%), insomnia (34%) and distress (72%) among healthcare workers who treated patients with COVID-19 (Lai et al., 2020). In North Rhine-Westphalia in Germany, the cumulative incidence of COVID-19 up to June 4 was 215 per 100,000 population with a mortality rate of 4.2 percent. Therefore, COVID-19 was a serious threat at that time. This can lead to an impairment of the mental health of the hospital staff who treat the affected patients. The city of Essen reported 874 cases with a COVID-19 infection until June 4th. At the University Hospital Essen more than 200 patients with COVID-19 were hospitalized between March and June 2020. During this period, medical staff were routinely exposed to patients with COVID-19. The effects on mental health of hospital employees in response to a pandemic differ individually and very likely depending on the proximity to patients with COVID-19 (Lai et al., 2020). In a different context, female gender has been found to be a predictor of the onset of posttraumatic stress disorders (PTSD) among military healthcare personnel after deployment (McGregor, et al., 2017). Anger is a common response to work-related life-threatening situations (Williamson, Stevelink & Greenberg, 2018). Female gender has also been reported to be an important indicator of the increasing anger of military medical personnel, which can be seen as an emotional indicator of the later occurrence of PTSD, anxiety disorders, or depression (Wesemann et al., 2017). The aim of this study was to assess gender differences in expressed anger of medical hospital staff working with patients with COVID-19. Due to the more frequent double burden on work and family life among German female workers, higher scores are expected for female workers.
