In this article, I made an exploratory study regarding the existence and the kinds of the self-formation mode in adolescence. The self-formation mode was defined as "a mode to promote self formation at a specific level, such as daily life and activities." In the study, 24 junior and senior female university students participated in the semi-structured interview and were asked to talk about how they changed and developed since they entered university. The analysis of their self-narratives revealed that there were several kinds of self-formation modes with different kinds. First, there were at least three kinds of self-formation modes from the perspective of activities: that is, the self-formation modes as "activity for achieving time perspective (SF1)", "basic activity for developing future (SF2)", and "activity without time perspective (SF3)." Second, SF1 was goal-oriented, while SF3 was not; SF2 was between these two. Adolescents with SF2 were interpreted not to have clear future goals, but to believe that basic activities could make their future. The article concluded with a discussion of how the positioning dynamics of SF2 especially had not been addressed in past studies of time perspectives and goals.
