New ICD-11 Clinical Descriptions and Diagnostic Guidelines for Mental and Behavioural Disorders: Improving Clinical Utility in the Practice of Psychology
A decade of work by the World Health Organization Department of Mental Health and Substance Abuse to develop the ICD-11 classification of Mental and Behavioural Disorders is nearing completion. As of the time of the Congress, the complete ICD-11 Clinical Descriptions and Diagnostic Guidelines (CDDG) will be available for public review and comment and a rigorous program of field testing will have been completed. This address will provide an overview of WHO's work in developing the CDDG and the major features of the new classification.

The development of a more accurate and more clinically useful classification of mental disorders in ICD-11 is an integral part of WHO’s public health efforts. WHO’s 194 member countries are required to report health statistics to WHO using the ICD as a framework, and most use it as a basic component of the architecture of their health care and health information systems. People can only have access to the most appropriate mental health services when the conditions that define eligibility and treatment selection are supported by a precise, valid, and clinically useful classification system. A better ICD will also help WHO to collect more accurate and more reliable information across the globe on the epidemiology and disease burden of mental disorders, how they present in health systems, and where we have the best opportunities for prevention and treatment, especially in settings where resources are scarce.

This presentation will describe major changes introduced in the ICD-11 CDDG and how these are intended to enhance both clinical utility and the ICD-11’s impact as a tool for reducing the global disease burden of mental and behavioural disorders. How these changes can improve the clinical utility of the classification as a part of the daily work of psychologists will be emphasized. Important innovations in several areas will be illustrated through clinical examples, including psychotic disorders, disorders specifically associated with stress, obsessive compulsive and related disorders, disorders due to substance use and addictive behaviours, and personality disorders.
