Abstract: Objective To explore the mediating effect of organizational identity between presenteeism behavior and turnover intention of clinical nurses in Chongqing. Methods From June to August 2023,the questionnaire survey was performed by the general information survey questionnaire,presenteeism behavior scale,organizational identity scale and turnover intention scale among 1 139 clinical nurses from six grade-A tertiary comprehensive hospitals in Chongqing,and the data were analyzed. Results The total scores of clinical nurses' presenteeism behavior,organizational identity and turnover intention were （4.96±1.81）,（30.30±6.92） and （13.37±3.90）points,respectively. The organizational identity was negatively correlated with presenteeism behavior and turnover intention（both P<0.01）,while the presenteeism behavior was positively correlated with turnover intention （P<0.01）. The organizational identity played a partial mediating role in the relationship between clinical nurses' presenteeism behavior and turnover intention,and the mediating effect accounted for 35.00% of the total effect. Conclusions The presenteeism behavior can not only directly affect turnover intention,but also indirectly affect turnover intention through the mediating effect of organizational identity. The hospital managers should take measures corresponding to nurses' presenteeism behavior and organizational identity to reduce their turnover intention.
