Abstract
This study examined the impact of job demands of responding to the COVID-19 on psychological burnout among disaster responders. Online survey data from 1163 participants from 17 public health centers across South Korea. Multiple regression and threshold regression analyses were conducted with subscales of the MBI-GS as dependent variables. Explanatory variables were categorized into the unique factor of responding to a novel infectious disease disaster and another factor of increased general job demands related to disaster response. The results showed that the unique and general job demands differentially affected on the disaster responders’ emotional exhaustion, cynicism, and sense of professional efficacy. Furthermore, the relationships of the variables with burnout differed at the threshold of three to four imposed tasks. Agency managers and policymakers should continue to recruit and train specialized personnel on an ongoing basis, reorganize job assignments, and consider avoiding overburdening a single responder during disaster response.
