Adolescents implement their own way of being through activities of self-experience, searching for new experience, contact with peers, attitudes towards authority, institutions and society. They try to be independent and autonomous which includes their capacity to think, feel and act uniquely, in their own way. In our previous study (Štěpánková, 2001) we focused on the adolescents' values, needs and attitudes towards selected existential topics (relationships to wright and wrong, responsibility, self-acceptation, self-confirmation, authenticity, etc.). In our qualitative research we found some differences between girls and boys, which corresponds to other research (Schwartz, S.H.& Howard, J. A., 1984; Eisenberg, N., 1986, 1996; Kotásková, J., 1987). In the present study we want to follow up and continue in exploring adolescents ways of thinking about themselveself and understanding their needs related to self.
