Drawing on the job demands-resources (JD-R) model and event system theory (EST), this study constructed a moderated mediating model to investigate the direct effect of career calling on work fatigue, the mediating effect of role overload, and the moderating effect of COVID-19 event disruption in the above relationships. We administered an online questionnaire to 488 Chinese police officers who participated in frontline work to prevent and control the COVID-19 pandemic. The results showed a U-shaped curvilinear relationship of career calling with physical fatigue, mental fatigue, emotional fatigue, and role overload. Moreover, role overload partially mediated these curvilinear relationships. In addition, COVID-19 event disruption positively moderated the direct curvilinear effect of career calling on role overload, physical fatigue, and emotional fatigue, as well as the first stage of the mediating effect in the relationship between career calling and physical, mental, and emotional fatigue through role overload. Furthermore, the direct U-shaped curvilinear effects and the indirect effects were more significant when COVID-19 event disruption was high.
本研究借鉴工作需求-资源（JD-R）模型和事件系统理论（EST），构建了一个有调节的中介模型，以考察职业使命感对工作倦怠的直接影响、角色过载的中介作用以及新冠疫情事件干扰在上述关系中的调节作用。我们对488名参与新冠疫情防控一线工作的中国警察进行了在线问卷调查。结果显示，职业使命感与身体倦怠、心理倦怠、情绪倦怠和角色过载呈U型曲线关系。此外，角色过载部分中介了这些曲线关系。此外，新冠疫情事件干扰正向调节了职业使命感对角色过载、身体倦怠和情绪倦怠的直接曲线效应，以及职业使命感通过角色过载对身体、心理和情绪倦怠影响的中介效应的第一阶段。此外，当新冠疫情事件干扰程度较高时，直接U型曲线效应和间接效应更为显著。
