The Diagnostic and Statistical Manual of Mental Disorders

Book Definition: The "Diagnostic and Statistical Manual of Mental Disorders" (DSM) is a comprehensive classification of officially recognized psychiatric disorders. DSM-IV was issued in 1993.


The DSM was first published in 1952, as a result of the increasing amount of psychiatrists during WWII. This was followed by revisions in 1968 (DSM-II), which closely involved the APA (American Psychological Association) and included 182 more disorders. The DSM-III was published in 1980, which was more consistent with the ICD (International statistical Classification of Disease and Related Health Problems). In 1987, the DSM-III-R was further revised, many categories were renamed and reorganized, while six were deleted and more were added. The DSM-IV included 297 disorders and is 886 pages long and then lead to the most recent edition, DSM IV-TR. The symptoms and general information about the diagnosis' were altered, however, none of the disorders were eliminated and no additions were made.
