Abstract:
One hundred ninety-nine case summaries of a consecutive sample of functional psychoses, which had been classified by Odegård, were diagnosed independently using DSM-III-R criteria by four experienced psychiatrists. Odegård's classification and DSM-III-R showed high concordance for schizophrenia and affective psychoses. Odegård's concept of reactive psychoses had high concordance with atypical psychoses in DSM-III-R. These findings imply that the results of genetic and follow-up studies from Scandinavia might be relevant for these diagnostic categories in DSM-III-R.
