ABSTRACT
The COVID-19 pandemic has created a variety of stressors, some of which have been linked to intense stress reactions, such as posttraumatic stress (PTS)-like symptoms. However, we have limited knowledge on cumulative effects of pandemic-related stressors on PTS or on variables that may mitigate the effects of these stressors. We aimed to address some of these knowledge gaps by testing three models to examine the interrelationships among pandemic-related stressors, perceived social support, coping flexibility, and pandemic-related PTS. The sample of this cross-sectional correlational study is comprised of 2291 adults from the United States who completed an online survey between 22 May 2020 and 15 July 2020. Results indicated that greater exposure to secondary stressors, but not COVID-19-related stressors, was associated with increased PTS. After controlling for COVID-19-related and secondary stressors, social support had negative direct and indirect (via coping flexibility) effects on PTS. In addition, social support mediated the effects of COVID-19-related and secondary stressors on PTS. Our findings highlight the complexity of the role of social support in relation to pandemic-related stressors and PTS, and suggest that early interventions that target social support and coping flexibility may help reduce pandemic-related PTS.
