Abstract: Objective: To explore the mediating effects of identity and job burnout in the relationship between perceived social support and general wellbeing among naval personnel. Methods: A crosssectional survey was conducted using cluster sampling among 1,559 Naval personnel from a certain naval unit between May and June in 2023, by the perceived social support scale (PSSS), general wellbeing scale (GWS), military identity scale (MIS), and Chinese military job burnout scale (CMJBS). Correlation analysis, regression analysis, and mediation effect test were performed. Results: Perceived social support was positively correlated with identity and general wellbeing (all P<0.01), and negatively correlated with job burnout (P<0.01). Identity was positively correlated with general wellbeing (P<0.01), while job burnout was negatively correlated with both military identity (P<0.01). Identity and job burnout were negatively correlated (P<0.01). Mediation analysis revealed that identity had medication effect on the relationship between perceived social support and general wellbeing (indirect effect=0.466, accounting for 56.08% of the total effect). Job burnout also served as a mediator (indirect effect=0.497, accounting for 59.81% of the total effect). Moreover, a significant chainmediating effect of identity and job burnout was observed (indirect effect=0.570, accounting for 33.36% of the total effect). Conclusion: The perceived social support can not only directly predict the general wellbeing, but also predict the latter indirectly through the mediating effect of identity and job burnout, as well as their chainmediating pathway.
