This study examines how cultural values (i.e., individualism and collectivism) and personality (i.e., self-perceived superiority and exhibitionism) jointly affect self-rating among Chinese respondents from mainland China (N= 161), Hong Kong (N= 350), and Taiwan (N= 398). The results demonstrated that respondents with a more individualistic cultural orientation exhibit greater leniency in self-rating than those with a more collectivistic cultural orientation. Furthermore, self-perceived superiority and exhibitionism are related to high self-ratings among individuals who expressed low individualism values, but not among individuals who expressed high individualism or collectivism values. The results suggest that self-rating research needs to take both the individual's cultural values and personality traits into account.
