Reliability of ICD‐10 research criteria: an Arab perspective

Abstract

Within a broader World Health Organization (WHO) collaborative research around the ICD-10 diagnostic criteria for research, the Regional Office for the Eastern Mediterranean (EMRO) ICD-10 research coordinating center at the Ain Shams Institute of Psychiatry presented the data collected from 8 Arab centers, which investigated a total of 233 patients using the local psychiatric interview schedules and diagnosed according to ICD-10 criteria. Interrater reliability was found to range between an almost perfect (0.81-1) to substantial agreement (0.61-0.80) (using the kappa coefficient) in diagnosing organic mental disorders, substance use disorders, schizophrenic, schizotypal and delusional disorders, affective disorders and neurotic and stress-related disorders. The categories of psychological development and child and adolescent disorders were diagnosed less frequently and the agreement between raters was lower. Though no culture-bound syndromes were encountered in any of the centers, difficulties in diagnosis using the research criteria were identified in the domain of simple schizophrenia and dissociative versus conversion disorders. These difficulties are discussed in consideration of the experience of our psychiatrists.
