Ego identity, egocentrism, and formal operations

This study examined the relationship between ego identity and formal operations and egocentrism in an adolescent population. Results indicated significant positive correlations between ego identity and formal operations and between ego identity and grade in school. Multiple regression analysis revealed that grade in school explained 21 percent of the variance while formal operational thinking, egocentrism, and sex accounted for only an additional 2 percent of the variance.
