The study is focused on the identity of the adolescents. The investigation offers to underline those four types of the psychological identity: the identity which can be obtained; the status of the moratorium; the premature identity and the diffuse identity. The adolescence verifies this growth, assuming, genuinely, consciously, and with one's own will, an orientation that gives meaning to one's life, with which one translates an intelligence of the world, and of one's internal and external reality, then communicates this world with the creativity of his/her own vision to become uniquely oneself, of value to oneself and to others. The results of this study can be used in a practical action of psychological service.
