Validation Of the Persian Version of The Mentalized Affectivity Scale (MAS) in Medical University Student

Mentalization is the cognitive and affective ability to understand the thoughts and feelings of ourselves and others.The purpose of this study was to investigate psychometric indices of Mentalized affectivity scale.

The research method is Psychometrics. The statistical population included all students of Isfahan University of Medical Sciences and the sample size consisted of 303 students who were selected by available sampling method and evaluated by the Mentalized affectivity scale. In order to prepare the Persian version of the Mentalized affectivity scale, the scale was first translated into Persian by one of the PhD students in Psychology, and after removing the ambiguities, it was approved by the professors of psychology at the University of Isfahan. After matching the translated version and the original version and after fixing the existing bugs, the final scale was prepared. In order to accurately measure the validity of the translated tool, its validity and reliability were examined. In order to investigate the validity of the translated instrument, Cronbachchr('39')s alpha coefficient were used to measure the reliability of the instrument. In order to measure the validity of the structure, the translated tool was examined using structural equations and confirmatory factor analysis using Smart-PLS software.

The implementation of confirmatory factor analysis confirmed the three-factor model of the research and obtained the fitting indices. The internal consistency of the scale, based on the Cronbachchr('39')s alpha coefficient, was 0.82 for the total score and 0.82 and 0.70, 0.89 and 0.91 for identifying, processing and expression emotion components. The correlation coefficients for convergent and divergent validity of the scale were statistically significant.

The Persian version of the Mentalized affectivity scale has a high reliability and validity and can be used as a useful tool for clinical research of psychologists and psychiatrists.
