Italian adaptation and psychometric analysis of the moral foundations questionnaire 2

Within the framework of Moral Foundations Theory (MFT; Haidt & Graham, Social Justice Research, 20(1), 98–116, 2007; Haidt & Joseph, Daedalus, 133(4), 55–66, 2004), the aim of the present study is to adapt and discuss the psychometric features of the Moral Foundations Questionnaire 2 (MFQ-2; Atari et al., Journal of Personality and Social Psychol ogy, 2023) in the Italian context. Utilizing a sample of 947 Italian adults, a Confirmatory Factor Analysis (CFA) was conducted, which confirmed the six-factor solution initially proposed for the MFQ-2. Each moral foundation demonstrated acceptable reliability, underscoring the robustness of the questionnaire’s internal consistency. Correlation analyses between the MFQ-2 and MFQ-1 dimensions indicate a significant consistency across the dimensions of both versions, affirming the convergent validity of the MFQ-2. Additionally, Multi-Group Confirmatory Analyses (MGCFAs) indicated that the MFQ-2 exhibits configural invariance across genders. Despite several limitations, this study provides precious insights into the adaptation process of the MFQ-2 for the Italian cultural context, contributing to a broader understanding of the MFT in Italy.
