and dissociative disorders

Abstract
Objectives: This symposium will be the fifth in a series of symposia focused on WHO’s ICD-11 and will
include presentations on the following topics: Obsessive-Compulsive and Related Disorders, Disorders
Specifically Associated with Stress, Bodily Distress Disorders, and Dissociative Disorders.
Methods: ICD-11 Working Groups were asked to review available scientific and other information about
use, clinical utility, and experience with relevant ICD-10 diagnoses; to review DSM-5 proposals and
consider whether they were suitable for global application; and to develop proposals for ICD-11 with a
focus on improving clinical utility in a broad range of settings. Proposals are currently being tested in
international field studies.
Results: ICD-11 will introduce a new grouping of Obsessive-Compulsive and Related Disorders,
including new categories of Hoarding Disorder, Body Dysmorphic Disorder, and Olfactory Reference
Disorder. There is reasonable consensus among researchers about the existence of an OCD spectrum, but
WHO field studies suggest that most clinicians do not currently conceptualize this grouping. Disorders
Specifically Associated with Stress is a new grouping for ICD-11, including new categories of Complex
Post-Traumatic Stress Disorder and Prolonged Grief Disorder and positive symptom requirements for
Adjustment Disorder. Bodily Distress Disorders encompass ICD-10 Somatoform Disorders, but pose
challenges in differentiating them from other groupings. Proposals for Dissociative Disorders incorporate
recent evidence about these phenomena. Results from field studies of these proposals will be presented.
Conclusions: Significant changes recommended for these diagnostic categories are being tested in field
studies that will inform the final ICD-11 and enhance the clinical utility of the classification.
