OBJECTIVES:Investigation is scare on job satisfaction among general practitioners (GPs) in China. This study aimed to investigate job satisfaction of GPs in China and explore its determinants. METHODS:A multistage-stratified random sampling method was used to collect data with a structured self-administered questionnaire from 3236 GPs (response rate, 99.8%) working in community health institutions in China between October 2017 and February 2018. Multiple linear stepwise regression analysis was used to analyze the associated factors with job satisfaction among GPs. RESULTS:Among these respondents, 1215 (37.5%), 352 (10.9%), and 1669 (51.6%) GPs were dissatisfied, moderate, and satisfied for their current job, respectively. Male GPs, a higher education level, at a higher professional title, at a lower level of income, and those with heavy work stress had a lower job satisfaction. In addition, GPs who often worked overtime, who were at a higher level of emotional exhaustion, at a higher level of depersonalization, at a lower level of personal accomplishment, and who had less occupational development opportunities reported a lower level of job satisfaction. CONCLUSION:These findings suggest that job satisfaction among Chinese GPs is at a moderate level. Region, sex, professional title, education level, working overtime, income level, emotional exhaustion, depersonalization, personal accomplishment, work stress, and occupational development opportunities were significant predictors of job satisfaction.
