The relationship between adolescence and schizophrenia is described, with emphasis on the importance of developmental evaluation in considering the formulation of a therapeutic program. The author points out the usefulness of involving the adolescent schizophrenic in the program of therapy: in controlling his own medication, in discussing and assenting to all environmental manipulations, and in feeling that psychotherapy sessions make him part of an alliance. Specific approaches to treatment are suggested, e.g., reality testing, application of the "so what" principle, and strengthening of useful defenses.Abstract Teaser
