Objective To empirically study the core competences evaluation index system for the doctor of public health (DrPH) in China, and to test its discriminant ability, reliability and validity. Methods This study designed the corresponding questionnaire in March 2025. The stratified cluster sampling method was used to select 200 doctors of public health who were enrolled from 2021 to 2024 to conduct a questionnaire survey in China. Cronbach’s α coefficient was used to assess reliability.Pearson correlation analysis assessed internal consistency. T test and F test assessed discriminant validity. Exploratory factor analysis assessed structural validity. Results A total of 189 questionnaires were retrieved. There were 189 valid questionnaires.The effective rate of questionnaire was 100%. The overall Cronbach’s α coefficient of the ability evaluation index system was 0.969, the Cronbach’s α coefficient of the basic knowledge dimension was 0.691, and the Cronbach’s α coefficient of other dimensions were above 0.8. The correlation coefficient between each dimension and the total score was between 0.5 and 0.9.There were statistically significant differences in core competence scores of public health doctors in different grades, public health practitioner certificates, public health practice experience and parents’ occupations (P<0.05). KMO value was 0.916,Bartlett’s spherical test value P<0.001, six common factors were extracted, and the total contribution rate of factor variance was 69.9%. Common factors could basically reflect the core concepts and main dimensions of the evaluation index system for the core competence of doctors in public health. Conclusion The core competences evaluation index system for the DrPH demonstrates good reliability and validity, indicating that it can serve as a tool for the training, evaluation, and assessment of the core competences for the DrPH.
