The DSM, including DSM-IV, is a registered trademark belonging to the American Psychiatric Association. It has attracted controversy and criticism as well as praise. There have been five revisions of the DSM since it was first published in 1952.
The last major revision was the DSM-IV published in 1994, although a "text revision" was produced in 2000. The DSM-V is currently in consultation, planning and preparation, due for publication in May 2012. An early draft will be released for comment in 2009. The mental disorders section of the International Statistical Classification of Diseases and Related Health Problems (ICD) is another commonly-used guide, and the two classifications use the same diagnostic codes.
