Methods From August 2019 to March 2020, the reliability and validity of the questionnaire were tested by proportional stratified sampling of 1 260 assistant dentist from 14 provinces and municipalities in China, and internal consistency test, content validity index and factor analysis were used. Results The content validity index of the self-assessment questionnaire of the self-assessment questionnaire is 0.86 and the overall Cronbach coefficient was 0.964. By exploratory factor analysis, 7 common factors were extracted, and the cumulative variance contribution rate was 71.49%. The main factors of each common factor were basically the same as the designed items. Conclusions The questionnaire has a good reliability, content validity and construct validity, which is helpful for the self-evaluation of the competency of assistant dentist in China.
