Psychometric properties and factor structure of the Persian version of Mentalized Affectivity Scale

Mentalized affectivity is a new approach that expresses the process of emotion regulation through a dynamic perspective. Since social-cognitive variables and cultural context play a major role in the process of mentalized affectivity, the present study aimed to assess the psychometric properties of the Mentalized Affectivity Scale in Iran.

A total of 447 students were selected via the convenience sampling method. The Persian version of Mentalized Affectivity Scale was administered simultaneously with other scales. exploratory and confirmatory factor analyses was used to evaluate the validity of the scale. Moreover, convergent validity and divergent validity of this scale were assessed with other scales. The reliability of the scale was calculated by Cronbach's alpha, coefficient theta, and composite reliability.

The results of exploratory factor analysis showed four factors of emotion recognition, emotion processing, emotion tracing, and emotion expression. The significant correlation of factors with the used scales pointed to the content validity and divergent validity of the scale. Cronbach's alpha coefficient for the entire scale was 0.93. The composite reliability of the factors was in the range of 0.82-0.89, and the coefficient theta of the scale was reported as 0.98. With respect to average variance extracted (AVE) greater than 0.5 and composite reliability greater than 0.8, the convergent validity of the factors was confirmed.

As evidenced by the obtained results, the Persian version of the Mentalized Affectivity Scale is a valid scale in the field of emotion regulation and social cognition that can be used for Iranian populations. The factor structure includes four factors.
