Morality-as-Cooperation Theory in Iran: Validation of the Persian Morality-as-Cooperation Questionnaire

Morality-as-Cooperation Theory (MAC) views moral values in terms of seven distinct domains. Given the recency of this theory and the paucity of empirical data putting it to the test from countries other than the theory’s birthplace, this study aimed to examine reliability and validity of Morality-as-Cooperation Questionnaire (N = 552) in Iran. A set of external scales assessing various values were used for assessing convergent validity of MAC-Q. Both correlated seven-factor and second-order individualizing-binding two-factor models showed good fit, particularly for separate Relevance and Judgement sections. The majority of MAC-Q, especially Judgement, subscales correlated significantly and most strongly with their corresponding external scales. Alphas were generally higher for Relevance than Judgement subscales. Moreover, MAC-Q, especially Judgement, made significant improvement over MFQ in predicting most external scales. We conclude by highlighting MAC-Q subscales in highest need of internal consistency enhancement or content refinement, as well as providing suggestions.
