[Psychosomatic aspects of adolescence].
During adolescence physical, psychic and social changes occure more rapidly and to a greater extent than during any other period of live. The marked changes concern not only the outern appearence, but also its intrapsychic representations, the body image. The complex integrative processes towards the identity as man or woman cannot be mastered without a certain emotional and physical instability. This is particularly the case if, in addition, nearly infantile disturbances in the socialisation or conflicts specific for this life period are, or have been, present. They can in the sense of a disposition lead to the manifestation of more or less severe crisis in adolescence. These crises interfere not only with the body image, but in many cases with the somatic functions as well. In the study three general aspects of this developmental problem are discussed as far they are relevant in the therapy of psycho-somatic disturbances in adolescents. 1. The implication of the adolescent phase in the course of psycho-somatic diseases. 2. Diseases which mainly occure in adolescence and are predominantly confined to this life period or are mainly influenced by it. 3. The influence which conflicts and phase-specific anxieties and fantasies exercise on the development and establishment of a mature body image and an adult identity.
