Abstract It is well established that one’s sense of morality may be readily influenced by one’s culture, education, and life situation. Very few psychometric tools are currently available to measure facets of human morality in different cultures. Therefore, the purpose of the present study was to develop a French adaptation of the Oxford Utilitarianism Scale (OUS-Fr) and formally evaluate its validity. The OUS-Fr was developed through a process of back-translation and administered to a sample of 552 participants. Results from exploratory factor analyses revealed a bidimensional structure with satisfactory loadings that was then also supported in the confirmatory factor analysis check. The OUS-Fr scale demonstrated good psychometric properties, with acceptable internal consistency and coherent results in the convergent validity analyses. These findings contribute to morality measurement literature by providing evidence for the reliability and validity of the French adaptation of the OUS. The OUS-Fr can be viewed as a valuable tool for researchers and practitioners for assessing utilitarian tendencies within the French-speaking population, which could pave the way for cross-cultural understandings that are important for fully understanding the intricacies of human morality.
