Objectives This study contributes to research on the paediatrician shortage by examining occupational identity, job satisfaction and their effects on turnover intention among pediatricians in China. Methods This study employed a multi-stage stratified random sampling method to conduct a questionnaire survey. Of the 4906 survey recipients, valid data were collected from 4198 of the respondents (85.6%). Participants were from seven regions of China (south, central, north, east, northwest, southwest, northeast). Pediatricians who volunteered and provided informed, written consent participated.All variables including basic socio-demographic and work-related characteristics, occupational identity, job satisfaction and turnover intention were based on available literature, and measured on a 5- point Likert scale.Such statistical methods as exploratory factor analysis (EFA), descriptive analysis, common method bias, one-way analysis, pearson correlation analysis and mediating effect analysis were used.Results There were significant differences among the respondents in terms of turnover intention based on age, education, marital status, region, type and grade of practice setting, professional title, years in practise, workload, rest days, and monthly income. Occupational identity and job satisfaction were both negatively related to turnover intention, and occupational identity was positively correlated with job satisfaction(r1=-0.601, p<0.001; r2=-0.605, p<0.001). And the result also showed that job satisfaction plays a mediating role in the association between occupational identity and turnover intention among Chinese pediatricians.Conclusions To reduce turnover intention among pediatricians in China, it is crucial to focus on three aspects: work condition, workload and salary. We suggest healthcare managers should increase investment in pediatric, carry out reforms on salary mechanism and pay more attention to female and young pediatricians.
