[An approach to adolescent psychology (author's transl)].

All physicians, not only psychiatrists and psychotherapists, must deal with adolescents in their daily practice. In this critical period of life, medical support, even of brief duration, if available at the right time, can have a decisive impact. The quality of the personal involvement of the adults in the adolescent's environment as well as that of his primary care physician is at least as important as a correct evaluation of his psychological problems.
