[Value of the family approach].

Studies of relations between schizophrenics and their family have considerably altered our understanding of the disease and its therapeutic approach. However, on the basis of a multidimensional concept of schizophrenia most clinicians consider that the familial approach should be integrated in the overall management of the patient and his family. Theories of communications integrated in the cybernetic model have thrown a new light on interactions between schizophrenics and their family. Behaviours that looked absurd when studied in isolation acquire a new meaning within the family context. The association of redundant functioning modalities detected in the families of schizophrenics are described. By clarifying the communications within the family and by assisting the members of the family, the patient can be given a chance of progressing.
