A. Okasha et al., DIAGNOSTIC AGREEMENT IN PSYCHIATRY - A COMPARATIVE-STUDY BETWEEN ICD-9, ICD-10 AND DSM-III-R, British Journal of Psychiatry, 162, 1993, pp. 621-626
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.
