Abstract
    [Objective] To analyse the role of epidemic risk perception in the relationship between eight biased constitutions(qi deficiency type,yang deficiency type,yin deficiency type,phlegm-dampness type,dampness-heat type,blood-stasis type,qi-depression type and special diathesis type) and quality of life(QOL). [Methods] An online survey was conducted in early 2022 during the epidemic of corona virnus disease 2019(COVID-19,3 to 15 February 2022) using the 30-item short version of Constitution in Chinese Medicine Questionnaire(CCMQ-30),Perceived Risk of COVID-19 Pandemic Scale(PRCPS),and World Health Organization Quality of Life-BREF(WHOQOL-BREF). A sample of 1 181 cases was obtained. [Results] Correlation analysis showed that scores of eight biased constitutions were negatively correlated with scores of QOL(r=-0.321 to -0.524,P<0.001),scores of eight biased constitutions were positively correlated with scores of epidemic perceived risk(r=0.168 to 0.225,P<0.001),and scores of epidemic perceived risk negatively correlated with QOL(r=-0.202,P<0.001). The results of the mediated effects test showed that the impact of scores of biased constitutions on QOL is dominated by direct effects. And the mediated effects of epidemic risk perception between biased constitutions and QOL were statistically significant(P<0.001). The scores of biased constitution had a predominantly direct effect on the negative impact of QOL. The mediating effect sizes of epidemic risk perception in descending order of importance is yang deficiency type(10.85%),special diathesis type(8.88%),dampness-heat type(8.21%),yin deficiency type(7.50%),blood-stasis type(7.44%),phlegm-dampness type(7.27%),qi-deficiency type(6.36%) and qi-depression type(4.98%). [Conclusion] In public health emergencies,perceived risk of epidemic played a partially mediating role in the relationship between biased constitution and QOL to varying degrees,but the mediating effect sizes were all small.
