DIAGNOSTIC AGREEMENT IN PSYCHIATRY - A COMPARATIVE-STUDY BETWEEN ICD-9, ICD-10 AND DSM-III-R

A random sample of 100 new patients referred consecutively to the psyc hiatric hospital was assessed using the Arabic translation of the PSE. An abstract form was designed to include all PSE scores as well as th e necessary extra data to make ICD-9, ICD-10, and DSM-III-R diagnoses. Kappa correlation was calculated for inter-rater and intra-rater reli ability. Overall reliability and reliability of each major psychiatric diagnosis were compared between the three systems. The use of the PSE helped in achieving good agreement between Arab psychiatrists for all the three systems, but ICD-10 was found to have the highest reliabili ty figures both for three-digit and four-digit psychiatric diagnoses.
