ABSTRACT=Abstract
Background: As experts studying occupational health psychology know, low level of work engagement leads to higher turnover intentions. Some researchers have put a focus on the association between organizational support and work engagement. However, little has been done concerning the mediating effect of psychological capital (PsyCap) on the association between perceived organizational support (POS) and work engagement (vigor, dedication, absorption) among Chinese doctors. 
Materials and methods: A cross-sectional study has been carried out from November to December in 2017, in Liaoning Province, China. The questionnaire consists of Survey of POS (SPOS), the Utrecht Work Engagement Scale (UWES), Psychological Capital Questionnaire (PCQ), demographic and working variables. The self-administered questionnaires were distributed to 1009 doctors. Effective responses were collected from 836 (82.85%) participants. Hierarchical multiple regression and the asymptotic and resampling strategies were used to examine the association between POS and work engagement mediated by PsyCap.
Results: After controlling the demographic and working variables, POS was positively related to vigor (β= 0.402; P < 0.01), dedication (β= 0.413; P < 0.01), absorption (β= 0.373; P < 0.01). PsyCap was positively associated with vigor (β= 0.442, P < 0.001), dedication (β= 0.413, P < 0.001), absorption (β= 0.395, P < 0.001). Thus, PsyCap (a × b= 0.1895, BCa 95% CI: 0.1524, 0.2290); (a × b = 0.1517, BCa 95% CI: 0.1180, 0.1875); (a × b= 0.1693, BCa 95% CI: 0.1299, 0.2099) significantly mediated the association between POS and vigor, dedication and absorption, respectively. 
Conclusion: There was a low level of work engagement among Chinese doctors. POS could indirectly improve vigor, dedication and absorption, partially through mediator PsyCap. POS intervention, education and training in PsyCap should be carried out to cope with work engagement.
