Objective: First treatment contact is preceded by a lengthy prodromal and psychotic prephase. We analysed the occurrence of symptoms and disabilities prior to first contact and their consequences for medium-term illness course. Method: A population-based sample of 232 first episodes of schizophrenia was studied retrospectively using the IRAOS and compared with matched peers from the population of origin. Further illness course was studied prospectively at six cross-sections over 5 years from first admission onwards. Results: Three quarters showed a prodromal phase of 5 years (mean) and a I-year accumulation of psychotic symptoms. First to appear were depressive and negative symptoms and early signs of cognitive and social impairment. Social disability emerged 4 to 2 years before first contact. Further illness course was determined by stage of social development at psychosis onset with the consequence of a significantly poorer course for men than women because of men's earlier illness onset. Symptomatology, type or onset. age and gender influenced social course via stage of social development and, additionally, via young men's socially adverse illness behaviour. Conclusion: Social course is determined by individual stage of social development at illness onset and by early illness course. Therefore, early detection and intervention are needed.
