SHOULD OCD BE CLASSIFIED AS AN ANXIETY DISORDER IN DSM-V?

In DSM-III, DSM-III-R, and DSM-IV obsessive-compulsive disorder (OCD) was classified as an anxiety disorder. In ICD-10, OD is classified separately from the anxiety disorders, although within the same larger category as anxiety disorders (as one of the neurotic, stress-related, and somatoform disorders). Ongoing advances in our understanding of OCD and other anxiety disorders have raised the question of whether OD should continue to be classified with the anxiety disorders in DSM-V This review presents a number of options and preliminary recommendations to be considered for DSM-V Evidence is reviewed for retaining OCD in the category of anxiety disorders, and for moving OCD to a separate category of obsessive-compulsive (OC)-spectrum disorders, if such a category is included in DSM-V Our preliminary recommendation is that OCD be retained in the category of anxiety disorders but that this category also includes OC-spectrum disorders along with OCD. If this change is made, the name of this category should be changed to reflect this proposed change. Depression and Anxiety 27:495-506, 2010. (C) 2010 Wiley-Liss, Inc.
