The classification of mental disorders in the Tenth Revision of the International Classification of Diseases

Abstract

SummaryThe chapter dealing with the classification of mental disorders in the Tenth Revision of the International Classification of Diseases (ICD-10) has been developed after consultation with experts in many countries. Each of the categories has been clearly defined so as to facilitate the assignment of diagnoses. The descriptions of categories and the diagnostic guidelines have then been tested in 110 centres located in over 40 countries, and the results have been used to finalize the text. The classification will be issued in several versions - one for statistical purposes, one for clinicians, one for researchers and one for general practitioners. A multiaxial presentation of the classification is being tested at present and will be made available in early 1993. The paper describes the requirements and principles which led to the classification, depicts the process outlined above and gives prospects for the future.
