Abstract：Objective To explore the internal mechanism of impact of public epidemic risk perception and acute stress reaction on quality of life (QOL) during the COVID-19 pandemic, and to provide a theoretical basis for improving public health in public health emergencies. Methods Perceived Risk of COVID-19 Pandemic Scale, Stanford Acute Stress Reaction Questionnaire, Revised Self-leadership Questionnaire and World Health Organization Quality of Life-BREF were used to conduct an online questionnaire survey during the short outbreak of COVID-19 in early 2021 (from February 3 to 10, 2021), and a total of 3,098 samples were collected accumulatively. Results The negative predictive effect of epidemic risk perception on QOL was significant (β=-0.48, t=-10.76, P<0.001). Moreover, the negative prediction of epidemic risk perception on QOL was still significant after the intermediary variable was added (β=-0.25, t=-5.68, P<0.001). The degree of acute stress response partially mediated the relationship between public epidemic risk perception and QOL, and the mediating effect accounted for 48.36% of the total effects. The interaction between self-leadership and acute stress response had a significant effect on the prediction of QOL β=0.001, t=2.068, P<0.05). Conclusion The degree of acute stress response and self-leadership had mediating and moderating effects on the relationship between public epidemic risk perception and QOL, respectively. We can reasonably perceive the risk of epidemic through adjusting the internal psychological mechanism so as to maintain and improve the public health status in public health emergencies.
