ICD-11 GUIDELINES

About the Guidelines

Since 2011, clinicians and researchers in the Global Clinical Practice Network have participated in field studies that tested the reliability, clinical utility, and global applicability of the ICD-11 Diagnostic Guidelines for Mental, Behavioural and Neurodevelopmental Disorders.

As the largest and most diverse clinical research network on mental health ever assembled, GCP.Network members and scholars, led by the Field Studies Coordination Group, engaged in systematic, online case-controlled studies and clinic-based field studies to evaluate and inform the proposed revisions to the ICD-11. More than 16,000 mental health practitioners representing more than 160 countries have participated and continue to participate in this dynamic body of research.

After more than a decade of rigorous field studies and regular convenings of clinicians and researchers around the world, the ICD-11 was approved by the World Health Assembly in May 2019. Following approval by the World Health Assembly, WHO member states can begin reporting health statistics based on the ICD-11 starting on January 1, 2022. It is expected that the transition for member states to adopt and implement the ICD-11 will take place over the next several years. 

We are pleased to make the ICD-11 guidelines available to all GCP.Network members. When viewing the Diagnostic Guidelines, please note that these documents are a pre-publication version and are to be used for educational purposes. Further edits may be made to these guidelines prior to their publication.
