Subsequently, exploratory factor analysis and confirmatory factor analysis was studied among 280 specialist and general physicians. Then, reliability was examined by calculating the intra-class correlation coefficient and investigating Cronbach&#39;s alpha coefficient.<br> <b>Results:</b> Cronbach&#39;s alpha coefficient for the whole scale was 0.849 and the intra-class correlation coefficient was 0.714. Content validity index was 0.849 and content validity ratio was 0.825. Exploratory factor analysis and confirmatory factor analysis resulted in a four-factors model including habitual action, understanding, reflection and critical reflection in the Iranian medical community.<br> <b>Conclusion:</b> The Persian version of Kember reflective thinking questionnaire with four factors has the desired reliability and validity in the Iranian medical community.
