Predicting the outcome of schizophrenia ten years later

Abstract

A total of 407 new admissions to Woodbridge Hospital, Singapore in 1975 with a diagnosis of schizophrenia were examined 10 years later to determine which variables were predictive of outcome. Useful predictors were marital status, duration of illness and Feighner's diagnostic criteria. Fairly useful predictors were age, sex and educational status. Race, family history, suicidal behaviour, thought disorder, affective blunting, delusions and hallucinations were not useful for predicting long term prognosis.
