Abstract: It has been demonstrated that self-concept consistency improves hedonic and eudaimonic well-being. However, culture may influence the relationship between them. Westerners are not only individualistic but also possess independent self-construal and low-level dialectical thinking. Therefore, their self-concept consistency is high and more predictive of their well-being. In contrast, Easterners are collectivistic, and they tend to have interdependent self-construal and high-level dialectical thinking. In this manner, their self-concept consistency is low and less predictive of their well-being. Future research should be conducted on other levels of personality besides dispositional traits and investigate different kinds of self-concept consistency and well-being. Moreover, they should also explore other cultural factors functioning in this process and investigate the comprehensive mechanism through which self-concept consistency and culture can influence well-being.

Key words: self-concept consistency, well-being, culture
