This refreshingly succinct paper makes a basic point and illustrates it with clinical cases. The author strongly believes that one should clearly recognize adolescent psychopathology when it exists rather than attempting to view it as a normal part of the "youth culture." Laufer focuses on the internal life of the adolescent as the chief determinant of pathological development. He believes that adolescent pathology in various forms represents "a breakdown in the process of integrating one's physically mature body as part of the representation of oneself." Using clinical illustrations, he points out that therapeutic intervention aiding the adolescent in this task of integration is not only desirable but crucial in resolving pathological patterns which may become fixed by the end of adolescence.
