[A systemic approach in psychotherapy]

The principle of the systemic disposition of psychotherapy is presented by the example of schizophrenic family systems. There is need of counteracting the "psychotic plays" with a communication of therapeutic strategies. The Heidelberg model works with five perspectives: the referred individuation, the delegation, the several-generations-dynamics of guilt and merit, and the status of mutuality. In schizophrenia family therapy seems to be very helpful also in the realm of a "family psychosomatics". The aim would be the introduction of a family medicine.
