This study examines the changes of relatedness levels in identity exploration among female adolescents along with the factors associated with the changes. The expanded Ego Identity Interview, which covers the domains of occupation, friendships, dating, and sex roles, was administered to university students (N=31) during their first semester as juniors and seniors and then again later in their senior year. Significant changes were noted from the lower to the higher levels in relatedness for three domains of occupation, friendships, and dating. The results suggest that the levels of relatedness develop during university years, and that the period between the first semester as juniors to the senior year is especially important to the changes from the lower to the higher levels in relatedness. The results for the factors associated with changes suggest that events in the proximal contexts for university students in Japan primarily influence their identity exploration from a relational viewpoint. As expected, job-seeking activity was the most crucial factor of the level change. It concludes that for university students in Japan, job-seeking activities contribute to personality development as well as getting a job in adolescence. (JDM)
