Diagnostic and Statistical Manual
The Diagnostic and Statistical Manual of Mental Disorders (DSM), of the American Psychiatric Association, lists the standard classifications of mental disorders as used by psychiatrists, psychologists, and other mental health professionals in the United States and some other locations.
The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) is the current edition and renders all previous editions obsolete.
In 1921, American Psychiatric Association was formed as a continuation of the former American Medico-Psychological Association. Editions of the DSM were published as follows:
- DSM-I: 1952
- DSM-II: 1968
- DSM-III: 1980
- DSM-III-R: 1987
- DSM-IV: 1994
- DSM-V: 2013
Somewhat related to the DSM is the World Health Organization's International Classification of Diseases which does include mental disorders. The terminology used has been coordinated between the two organizations for several editions of both publications.
