Perceived organizational support and PTSD symptoms of frontline healthcare workers in the outbreak of COVID-19 in Wuhan: The mediating effects of self-efficacy and coping strategies.

The present study aimed to examine the effect of perceived organizational support on the PTSD symptoms of frontline healthcare workers, and to examine the mediating effects of coping self-efficacy and coping strategies in this relationship. A short-term longitudinal study design was used to conduct two waves of online surveys in March and April 2020. Participants comprised 107 medical staff in both waves of investigation. Self-efficacy, coping strategies, and perceived organizational support were reported at Wave 1, and PTSD symptoms were reported at Wave 2. Results indicated that (1) The prevalence of probable PTSD was 9.3% and 4.7% on the Chinese version of the Impact of Events Scale-Revised of 33 and 35, respectively. Local healthcare workers had greater risks of PTSD than the members of medical rescue teams. Doctors reported higher PTSD symptoms than nurses. (2) Perceived organizational support had a significant indirect effect on PTSD symptoms through the mediation of problem-focused coping strategies and the sequential mediating effect of coping self-efficacy and problem-focused coping strategies. The findings highlight the importance of providing adequate organizational support to reduce PTSD symptoms in frontline medical staff during the COVID-19 pandemic.
