Abstract: Objective To investigate the current status and correlation of social support,psychological resilience,occupational stressor and turnover intention among couriers in Beijing. Methods From October 2023 to May 2024,a total of 468 couriers in Beijing who came to health management center of Beijing Rehabilitation Hospital of Capital Medical University for health examination were selected as the survey objects. The general information questionnaire,occupational stressor scale（OSS）,Connor-Davidson resilience scale（CD-RISC）,perceived social support scale（PSSS） and turnover intention questionnaire were used for the survey,and the data were analyzed. Results The scores of occupational stressor,psychological resilience,social support and turnover intention of couriers in Beijing were （85.83±11.28）,（68.23±9.84）,（65.23±8.46） and （10.48±2.81）points,respectively. Occupational stressor was positively correlated with turnover intention,social support was positively correlated with psychological resilience（r=0.579,0.539,both P<0.01）,while psychological resilience and social support were negatively correlated with occupational stressor（r=-0.523,-0.542,both P<0.01）,psychological resilience and social support were negatively correlated with turnover intention（r=-0.493,-0.382,both P<0.01）. The mediating effect analysis showed that social support,psychological resilience played intermediary role between occupational stressor and turnover intention of couriers,accounting for 17.35% and 15.98% of the total effect,respectively.Social support-psychological resilience played a chain intermediary role between occupational stressor and turnover intention,accounting for 8.24% of the total effect and 19.82% of the total intermediary effect. Conclusion The social support and psychological resilience have multiple mediating effects between occupational stressor and turnover intention among couriers in Beijing.
