[A longitudinal study of university students' identity dimension development].
One hundred and twenty-five freshmen in an education/psychology department t. (56 males and 69 females) and 63 psychology major juniors of the same department. (27 males and 36 females) were administered an identity dimension (ID) scale and a questionnaire on crises and commitments in 11 areas during June 1984. Surveys were repeated with these subjects on February and June '85, and February '86. The principal results were as follows: (a) the number of high ID score students increased in junior and senior years; (b) ID scores were distributed in a two peaked form at graduation; (c) female subjects' levels of crises with 'same-sex friends', 'opposite-sex friends', and on 'study' decreased corresponding with the increase of ID scores; male subjects' levels of crises with 'opposite-sex friends' and on 'desirable life styles and values' increased corresponding with the decrease of ID scores.
