[Premorbid and social markers of patients with schizoaffective psychoses].

The present study reports on findings in international literature regarding premorbid and social factors of schizoaffective patients and also own findings of the Cologne study (72 schizoaffective patients with a mean follow-up period of 25.6 years). Altogether it can be said that more women suffer from schizoaffective disorders than men. The mean age at first manifestation is higher than that of schizophrenic patients and lower than that of affective disorders, although schizoaffective disorders can occur at any age. Premorbid social adjustment and ability to form a stable heterosexual partnership before onset are good in schizoaffective patients. There seems to be no special premorbid personality of schizoaffective patients. Education and level of vocational training are generally good. Only a few schizoaffective patients belong to the lower social classes. Most schizoaffective patients do not come from a "broken home". Although "life events" are frequent in a schizoaffective population, the relevance of this finding has to be limited: If we evaluate "life events" in regard to single episodes, we find that most episodes, especially episodes occurring during the later course, do not have precipitating factors. In conclusion, it can be said that - besides the already known better prognosis of schizoaffective disorders - several differences exist regarding premorbid and social factors, between schizoaffective disorders and schizophrenia.
