Abstract

Introduction: Moral psychologists have long sought to formulate moral values and assess individuals’ and groups’ moral profiles. To this end, following criticisms to the Moral Foundations Theory and its questionnaire (Graham et al., 2011, 2013), Curry (2016) proposed Morality-as-Cooperation (MAC) Theory based on biological evolution and by centralizing cooperation in defining morality. This theory views moral values in terms of seven distinct domains, i.e., Family, Group, Reciprocity, Heroism, Deference, Fairness, and Property. The corresponding scale is Morality-as-Cooperation Questionnaire (MAC-Q; Curry et al., 2019) which is composed of separate sections, namely, Relevance and Judgement. Given the recency of this theory and the paucity of empirical data putting it to the test from countries other than its birthplace, this study aimed to examine reliability (internal consistency) and validity (convergent, divergent, predictive, and incremental) of the Persian version of MAC-Q among Iranians.
Method: The final sample consisted of 552 Iranians above 18 years of age (58.9% female, mean age 31.03, SD = 10.24 years) for the initial MAC-Q structural analyses, and 370 Iranians (51.6% female, mean age 32.65, SD = 10.33 years) for the analyses aimed at convergent, divergent, and predictive validity. Materials included the Persian translation
of 42-item MAC-Q (Curry et al., 2019) and the MFQ-20 (Graham et al., 2011; Nejat & Hatami, 2019), along with a set of external scales relating to the moral values represented in the MAC Theory. Among these scales were Schwartz’s Basic Values Scale, Family Values Scale, Virtues in Action Scale, and Social Dominance Orientation scale. The scales were made available online to respondents. Confirmatory factor analysis, correlation, and hierarchical regression analysis were used for data analysis.
Findings: Cronbach’s alpha coefficients for the Relevance section were higher than .70 except Fairness (.66). For Judgement, Heroism, Fairness, and Property had low internal consistency (below .60) while alphas for the rest of domains were higher than .60. In general, alpha coefficient were higher for the Relevance than the Judgement section. The correlated seven-factor and the hierarchical individualizing-binding two-factor model had good fit in confirmatory factor analysis, especially separately for Relevance and Judgement sections. The majority of MAC-Q subscales, particularly those of Judgement, were significantly and most strongly correlated with their corresponding external scales, suggesting a satisfactory convergent validity for the questionnaire. MAC-Q, especially the Judgement section of it, predicted the majority of the value-related external scales above and beyond Moral Foundations Questionnaire, a finding which indicates good predictive and incremental validity of the Persian MAC-Q.
Discussion: The internal consistency of Judgement Property was similar to Yilmaz et al. (2021) but lower than Curry et al. (2019), while that of Judgement Fairness and Heroism tended to be lower than both. Findings supported the distinctiveness of the MAC theory’s seven moral values among Iranians. Second, similar to prior findings on moral foundations, these seven moral concerns were found to be categorized under two broader individualizing (Fairness, Property, and Reciprocity) and binding (Group, Family, and Heroism) categories. The present study replicated former findings regarding better model fit in separate sections of the questionnaire than the whole of it, with slightly better fit for the Relevance than the Judgement section. However, the Judgement section fared better
than Relevance in convergent and incremental validity. Therefore, while echoing the recommendation to use Relevance and Judgement sections separately, similar to Curry et al., one section could not be strictly preferred to the other in the Persian scale.
