The Polish adaptation of Moral Foundation Questionnaire (MFQ-PL)

This study presents results of the Polish adaptation and validation procedure of Moral Foundation Questionnaire - a tool for measuring five moral foundations postulated by Moral Foundations Theory by J. Haidt and collaborators (Graham et al., 2011, 2013; Haidt, 2014) - Care/Harm, Fairness/cheating, Loyalty/betrayal, Authority/subversion, and Sanctity/degradation. Psychometric properties of MFQ-PL were evaluated in two samples (N1 = 570, N2= 326) and in aggregated sample, N = 896. Confirmatory analysis (CFA) provided support for five factor model proposed by the theory. This result and high level of temporal stability measure suggest high reliability of MFQ-PL. Our research alongside with other cited studies that employ MFQ-PL confirms high validity of the adapted questionnaire. Also, the research supports the universality of the structure of moral foundations across cultures. The findings proves that MFQ-PL is a reliable and valid tool for measuring scores on five moral foundations. peerReviewed publishedVersion
