Development and testing of a post competency scale for traditional Chinese medicine physicians undergoing standardized training

Objective To develop and test a post competency scale for traditional Chinese medicine (TCM) physicians undergoing standardized training to provide an applicable tool for scientific evaluation. Methods Based on literature analysis, behavioral event interviews, and expert consultations, measurement questions were formulated and the initial scale was designed. A questionnaire survey was conducted from July 2022 to May 2023 among TCM physicians undergoing standardized training in China. The rationality of the scale was confirmed through item purification, factor analysis, and tests of reliability and validity. Results The post competency scale consisted of three dimensions (TCM fundamentals and research abilities, TCM thinking and skill abilities, and personal traits and communication abilities) with 21 items. Exploratory factor analysis identified three common factors, accounting for a cumulative variance contribution rate of 62.165%. Confirmatory factor analysis demonstrated that the fit indices of the three-factor model fell within a relatively ideal level. The Cronbach's alpha coefficient of the scale was 0.885. Through convergent validity analysis, the standardized loading coefficients of the 21 items were >0.5, and the average extracted variance (AVE) of the three factors was also >0.5. Moreover, the square roots of the AVE values for each dimension exceeded the correlation coefficients between it and the other dimensions. Conclusions The findings suggest that the post competency scale of TCM physicians undergoing standardized training can provide a reliable scientific basis for training and assessment within China.
