Design and psychometric properties of an instrument to assess metacognition in moral reasoning in medicine.

Aim: The present study aims at designing and assessing the psychometric properties of MCMR instruments to lead the medical ethics education to further goals and more definite steps.

Design: This is a cross sectional study.

Method: This study was conducted in two phases; identifying the items and designing the instrument. In the preliminary phase, the qualitative study was carried out using conventional content analysis method. In the second phase, psychometric evaluation of instrument was done using face and content validity, construct validity and reliability.

Results: On the first phase of this study, 135 items were identified. After determining face and content validity, 111 items reached the stage of exploratory factor analysis. This instrumental analysis indicated the existence of 74 items and ten factors whose variance of the total is explained as 46.883%. Cronbach's alpha value was 0/75. And the intra-cluster correlation coefficient was 0.808.
