Mentalization Scale (MentS): Validity and reliability of the Iranian version in a sample of nonclinical adults.

INTRODUCTION: Mentalizing incapacity is increasingly identified as a common factor in psychopathology. The Mentalization Scale (MentS) is a cost-effective measure built upon the dimensional model of mentalizing. We aimed to evaluate the psychometric properties of the Iranian version of MentS. METHODS: Two samples of community-based adults (N1  = 450, N2  = 445) completed different batteries of self-report measures. In addition to MentS, participants completed measures of reflective functioning and attachment insecurities in the first sample and a measure of emotion dysregulation in the second sample. RESULTS: Due to the conflicting results of confirmatory and exploratory factor analyses, an item-parceling approach was applied, which replicated the original three-factor structure of MentS, yielding Self-Related Mentalization, Other-Related Mentalization, and Motivation to Mentalize. The reliability and convergent validity of MentS were supported in both samples. CONCLUSION: Our findings provided preliminary evidence for using the Iranian version of MentS in nonclinical populations as a reliable and valid measure.

Emotion dysregulation as mediator between mentalizing capacity and affective states: An exploratory study.

Aim: We intended to elucidate the relationship between mentalizing capacity and affective states by investigating the mediatory role of emotion dysregulation. Methods: A sample of nonclinical Iranian adults (N = 445) completed a battery of online self-report measures comprising the Positive and Negative Affect Schedule (PANAS), Mentalization Scale (MentS), and Difficulties in Emotion Regulation Scale (DERS). Results: Correlational analyses demonstrated that self- and other-related mentalizing were significantly and inversely associated with emotion dysregulation, which in turn was strongly linked with positive and negative affects. Using structural equation modeling, the results delineated emotion dysregulation as a mediator between self- and other-related mentalizing and affective states, predicting higher negative and lower positive affects. However, motivation to mentalize failed to predict positive affects and only contributed to lower negative affects directly. Conclusion: Mentalizing capacity was found to be indirectly linked with affective states through emotion dysregulation; hence, along with the previously substantiated association between emotion dysregulation and affective states and the partially established relationship between mentalizing capacity and affective states, we propose mentalizing incapacity to be at fault in the development of affective difficulties.

Psychometric properties of the parental reflective functioning questionnaire in Iranian mothers.

This study aims to examine the psychometric properties of the Persian version of the Parental Reflective Functioning Questionnaire (PRFQ) in mothers, a brief self-report measure that assesses parental mentalization capacity. To examine the factor structure and construct validity of the PRFQ, 430 mothers of 3-6-year-old children completed the Persian version of the PRFQ (Persian-PRFQ) along with the Emotion Regulation Checklist (ERC) and the Strengths and Difficulties Questionnaire (SDQ). Exploratory and confirmatory factor analyses supported the three-factor structure of the PRFQ. Convergent validity was confirmed for the three subscales of the PRFQ, while divergent validity was only confirmed for the PM and IC. Furthermore, the mean score of the certainty of mental states (CMS) in this sample was higher than in other studies, and contrary to the theoretical foundations, the CMS was positively related to interest and curiosity in mental states (IC). In conclusion, our results provided initial evidence for the use of the Persian-PRFQ in the Iranian population.

The Effectiveness of a Parent-Training Program for Promoting Cognitive Performance in Preschool Children.

The study aims to evaluate the effectiveness of a parent training program for promoting cognitive performance of young children through enriching the parent-child interactions among mothers of preschool-aged children in Mashhad, Iran. A total of 29 couples of mothers and their children were assigned to an experimental group (n = 16 couples) and a control group (n = 13 couples). Mothers in the experimental group participated in 12 weekly sessions and were trained how to enrich their daily parent-child interactions as such. Children's cognitive performance was assessed by three subscales of the Wechsler Preschool and Primary Scale of Intelligence (WPPSI). The results of the analysis of covariance (ANCOVA) indicated a significant difference between the experimental and control group. The findings support the effectiveness of the parent training program for enhancing cognitive performance in preschoolers.
