CONFERENCE ABSTRACT
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.
