Since 1952, the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders has been the official manual for diagnosing mental disorders in the United States. It provides the specific criteria that are used in clinics and hospitals to diagnose various mental disorders. Treatment recommendations, as well as payment by health care providers, are often determined by DSM classifications.
The most recent edition of the Diagnostic and Statistical Manual, the DSM-5-TR published in 2022, is a minor update of 2013’s DSM- 5. The DSM-5 itself was a significant revision of the previous manual. Modifications were made in the criteria used to identify a number of disorders, and a few new disorders were added. An important change was made in the classification of OCD. It was removed from the category of anxiety disorders, and put in a separate category. OCD’s diagnostic criteria were also somewhat broadened to include cases that would not have been diagnosed as OCD in the past. A number of noted OCD researchers did not agree with these changes. I think that removing OCD from the category of anxiety disorders was a mistake, because OCD has always been categorized as such, and, after all, OCD is first and foremost a disorder of fearful thoughts.
