[Systems theory reflections on the treatment of the acute and post-acute stage of schizophrenic psychoses].

Biological, psychical and social phenomena of acute and postacute phase of schizophrenic psychoses are differentiated according to systems theory. During the acute phase the therapeutical interventions aim to stabilize mainly the biological and psychical sphere, whereas for the post-acute phase the emphasis lays on the psychical and social phenomena. This phase-oriented coupling between the therapist, the patient and his/her social network promotes a successive restructuring by generating consensual spheres, which help the patient and his/her social net to find new ways for autonomous development.
