The reliability of psychiatric diagnosis in Israel's Psychiatric Case Register.
To determine the reliability of psychiatric diagnoses in the Israel Psychiatric Case Register, DSM-III criteria were applied to case record abstracts of first admissions to a large psychiatric hospital in Jerusalem. The DSM-III diagnoses were compared with ICD-8 records diagnoses. Between 40 and 50% of those originally diagnosed as schizophrenia were re-diagnosed into less severe categories. The proportion diagnosed as affective disorder doubled from 21% for ICD-8 diagnoses to 40% for DSM-III diagnoses. The unreliability concerned the diagnoses of schizophrenia and affective disorder. Findings suggest that the introduction of standardized diagnostic criteria in Israel will lead to a substantial increase in the number of cases diagnosed as affective disorder, although difficulties involved in differentiating schizophrenia from the major affective disorders remain. The DSM-III findings suggest a high prevalence of affective disorders among Jews.
