Translation and psychometric evaluation of the reflective capacity scale in Iranian medical education.

Background: Examining the reflective capacity in medical students is a principal step for the development of effective educational strategies to improve it. Reflection scales available in Iran are inadequate due to the lack of focus on students' willingness and tendency to participate in reflection. This study aimed at translation and psychometric evaluation of "Reflective Capacity Scale" in Iranian medical education.

Methods: This methodological research was completed in two parts: translation and psychometric evaluation. After getting permission from the main developer of the tool, the translation process was done based on Polit and Yang model in Persian language. Then, face validity and content validity of the tool were established using a qualitative method. Construct validity was surveyed with exploratory and confirmatory factor analysis via completing the questionnaire by 320 medical students, who were selected using convenience sampling. The reliability of the tool was also checked with two methods of internal consistency and stability. The gleaned data were analyzed with SPSS20 and AMOS.

Results: "Reflective Capacity Scale" includes 16 items that were retained after cross-cultural translation. Face validity and content validity were acceptable. By performing exploratory factor analysis, four factors were identified that accounted for 63.79% of the total variance. In the confirmatory factor analysis, the values of the fit indices confirmed the appropriate fit of the model. The internal consistency reliability of the whole tool was equal to 0.83 and the intra-class correlation coefficient was equal to 0.98.

Conclusion: The translated and validated "Reflective Capacity Scale" provides a robust tool for assessing reflective capacity among Iranian medical students. Its validity and reliability underscore its potential for measuring the reflective capacity of medical students.
