If a person has different values from their culture, they are most likely to have a healthy self-concept.

In individualistic cultures, people must comply with social order and fit in with social roles to have a healthy self-concept. In collectivistic cultures, people must achieve personal goals and fulfill social roles to have a healthy self-concept. In collectivistic cultures, self-concept is affected more by culture because of the social pressure to conform.
