Culture, identity consistency, and subjective well-being.

This research revisits the classic thesis in psychology that identity consistency is a prerequisite condition of psychological well-being and finds that people with a more consistent self-view had a more clear self-knowledge, were more assertive, and had self-experiences that were less affected by the perspectives of others.

Abstract

All individuals have multiple views of themselves. Whereas the consistency among the different aspects of identity is emphasized in Western cultures, the "multiple selves" are often viewed as coexisting realities in East Asian cultures. This research revisits the classic thesis in psychology that identity consistency is a prerequisite condition of psychological well-being. Between individuals (Study 1), people with a more consistent self-view had a more clear self-knowledge, were more assertive, and, most notably, had self-experiences that were less affected by the perspectives of others. Compared with North American participants (Study 2), Koreans viewed themselves more flexibly across situations, and their subjective well-being was less predictable from levels of identity consistency. Also, consistent individuals received positive social evaluations from others in the United States but not in Korea.
