The purpose of this study based on Ego Identity Status Approach was to examine the processes and their factors about identity development in late adolescence from "crisis" and "commitment" point of view in the past and present, and the transition pattern of Ego Identity Status. The main results were as follows: The way of rating Ego Identity Status should be revised regarding "commitment" (Marcia, 1966), that is "have explored / be committing", "be exploring / will be committing", "cannot explore / cannot commit", "intend not to explore / intend not to commit", and "have not explored / is committing." Ego Identity Status in the past was rated by "crisis" and "commitment", and one in the present was classified by "crisis", "commitment", and "future perspective." And "future perspective" was available for classifying Identity Achievement and Moratorium. This study proved that the identity development in late adolescence was explained as a process of "self-identity → psychosocial-identity" (Mizokami, 2004). The other side, identity development on the transition pattern of "D1 (Identity Diffusion 1) → Dl" was blocked because second separation-individuation was unsolved.
