Developing a Japanese version of the Moral Foundations Vignettes (MFV-J)

The Moral Foundations Vignettes (MFV, Clifford et al., 2015) was developed to measure moral attitudes using scenarios involving fictional individuals engaging in morally offensive behavior. Here, we present a Japanese version of the Moral Foundations Vignettes (MFV-J) and examine its validity. Analysis of the responses from 443 participants suggested that the best-fit model was a nine-factor model, which the original study theoretically assumed. To assess construct validity, we examined the association between each factor of the MFV-J and the Japanese version of the Moral Foundations Questionnaires. These results demonstrate a pattern similar to those reported in previous studies. Based on these results, the usefulness of the MFV-J is discussed.
