Editing Dissociative identity disorder (section)

====Re-classifications====
The DSM-III intentionally omitted the terms "hysteria" and "neurosis", naming those as Dissociative Disorders, which included Multiple Personality Disorder,<ref>{{Cite book |last1=American Psychiatric Association |url=http://archive.org/details/diagnosticstatis00amer_1 |title=Diagnostic and statistical manual of mental disorders : DSM-III-R |last2=American Psychiatric Association.

In the opinion of [[McGill University]] psychiatrist Joel Paris, this inadvertently legitimized them by forcing textbooks, which mimicked the structure of the DSM, to include a separate chapter on them and resulted in an increase in diagnosis of dissociative conditions. Once a rarely occurring spontaneous phenomenon (research in 1944 showed only 76 cases),<ref>{{cite news |title=''Creating Hysteria'' by Joan Acocella |year=1999 |newspaper=[[The New York Times]] |type=book review |url=https://www.nytimes.com/books/first/a/acocella-hysteria.html}}</ref> the diagnosis became "an artifact of bad (or naïve) psychotherapy" as patients capable of dissociating were accidentally encouraged to express their symptoms by "overly fascinated" therapists.<ref name=Paris2008>{{cite book |isbn=978-0-19-531383-3 |last=Paris |first=J |year=2008 |publisher=[[Oxford University Press]] |title=Prescriptions for the Mind: A Critical View of Contemporary Psychiatry |page=[https://books.google.com/books?id=g66_hwnQHU8C&pg=PA92 92]}}</ref>

"Interpersonality amnesia" was removed as a diagnostic feature from the DSM III in 1987, which may have contributed to the increasing frequency of the diagnosis.<ref name = Kihlstrom/> There were 200 reported cases of DID as of 1980, and 20,000 from 1980 to 1990.<ref name="pmid7788115">{{cite journal | author = Merskey H | title = Multiple personality disorder and false memory syndrome | journal = [[British Journal of Psychiatry]] | volume = 166 | issue = 3 | pages = 281–283 | year = 1995 | pmid = 7788115 | doi = 10.1192/bjp.166.3.281 | doi-access = free }}</ref> [[Joan Acocella]] reports that 40,000 cases were diagnosed from 1985 to 1995.<ref name="Accocella">{{cite book |last=Acocella |first=JR |author-link=Joan Acocella |title=Creating Hysteria: Women and Multiple Personality Disorder |publisher=Jossey-Bass |location=San Francisco |year=1999 |isbn=978-0-7879-4794-1 |url=https://archive.org/details/creatinghysteria00acoc }}</ref> Scientific publications regarding DID peaked in the mid-1990s, rapidly declined,<ref name = Pope/> then has continued on a steady increasing trend since.<ref name=boysen2024/>

In 1994, the fourth edition of the DSM replaced the criteria again and changed the name of the condition from "multiple personality disorder" to the current "dissociative identity disorder" to emphasize the importance of changes to consciousness and identity rather than personality. The inclusion of interpersonality amnesia helped to distinguish DID from [[dissociative disorder not otherwise specified]] (DDNOS), but the condition retains an inherent subjectivity due to difficulty in defining terms such as personality, identity, ego-state, and even [[amnesia]].<ref name = Kihlstrom>{{cite journal | author = Kihlstrom, J.F. | year = 2005 | title = Dissociative disorders | journal = Annual Review of Clinical Psychology | volume = 1 | pages = 227–53 | pmid = 17716088 | doi = 10.1146/annurev.clinpsy.1.102803.143925 | issue=1}}</ref> The [[ICD-10]] classified DID as a "Dissociative [conversion] disorder" and used the name "multiple personality disorder" with the classification number of F44.81.<ref name = ICD10/> In the [[ICD-11]], the [[World Health Organization]] have classified DID under the name "dissociative identity disorder" (code 6B64), and most cases formerly diagnosed as DDNOS are classified as "partial dissociative identity disorder" (code 6B65).<ref>{{cite web |title=ICD-11 for: 6B65 Partial dissociative identity disorder |series=Mortality and Morbidity Statistics |website=icd.who.int |url=https://icd.who.int/browse11/l-m/en#/http://id.who.int/icd/entity/988400777 |access-date=2022-05-25}}</ref>
