Assessing the Psychometric Properties of the Persian Version of Brief-mentalized Affectivity Scale

Objectives Despite the increasing importance of emotion regulation, there are limited scales for its assessment. Mentalized affectivity theory proposes a novel perspective on emotion regulation. This study aims to investigate the psychometric properties of the Persian version of briefmentalized affectivity scale (B-MAS). Methods This is a descriptive psychometrics study. Participants were 414 students from Tarbiat Modares University, Tehran University, and Shahid Beheshti University in the academic year 2022-2023, who were selected by a convenience sampling method. They completed the Persian versions of B-MAS, ten-item personality inventory (TIPI), satisfaction with life scale (SWLS), Beck anxiety inventory (BAI), and difficulties in emotion regulation scale (DERS). Construct validity was evaluated using confirmatory factor analysis (CFA). Convergent and divergent validity were assessed by the Pearson correlation test. Internal consistency (using Cronbach’s α), test re-test reliability, and composite reliability were also evaluated. Results The CFA results confirmed the three-factor solution (identifying, processing, and expressing) and showed the good fit of the model. The significant correlation of the Persian B-MAS score with the BAI, TIPI, SWLS, and DER scores confirmed its convergent and divergent validity. Cronbach’s α for the three factors was from 0.86 to 0.88. Test re-test reliability for the three factors was from 0.75 to 0.80. Composite reliability was from 0.79 to 0.82. Conclusion The Persian version of B-MAS with three subscales has acceptable validity (construct, convergent, divergent) and reliability for psychological studies on the Iranian population.
