Preliminary data on the psychometric proprieties of the italian version of the reflective functioning questionnaire

Abstract

Introduction Assessing mentalizing abilities is a complex issue. Only recently an instrument assessing mentalizing capacity as a whole, the Reflective Functioning Questionnaire (RFQ), has been developed. Objectives To reach the purpose of our study, we investigated the psychometric proprieties of the Italian version of the RFQ. Methods The study was conducted on a sample including a group of violent offenders and a group of community participants. All subjects fulfilled the RFQ, the Personality Inventory for DSM-5 (PID-5) and the Aggression Questionnaire (AQ). Results The theoretical model was defined and analysed by using Partial Least Squares–Path Modelling with high-order construct definition. Data showed good psychometric proprieties of the Italian version of the RFQ. Also, specific patterns of correlations were identified between the RFQ subscales and both PID-5 and AQ scores. Offenders significantly differed from controls only in relation to one subscale of the RFQ. Conclusions Data supported the factorial structure of the RFQ found in the original validation study. Results also support the existence of a second-order variable, mentalizing, resulting from the convergence of hypomentalizing and hypermentalizing.
