<P> "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 . There were 200 reported cases of DID as of 1980, and 20,000 from 1980 to 1990 . Joan Acocella reports that 40,000 cases were diagnosed from 1985 to 1995 . Scientific publications regarding DID peaked in the mid-1990s then rapidly declined . </P> <P> There were several contributing factors to the rapid decline of reports of multiple personality disorder / dissociative identity disorder . One was the discontinuation in December 1997 of Dissociation: Progress in the Dissociative Disorders, the journal of The International Society for the Study of Multiple Personality and Dissociation . The society and its journal were perceived as uncritical sources of legitimacy for the extraordinary claims of the existence of intergenerational satanic cults responsible for a "hidden holocaust" of Satanic ritual abuse that was linked to the rise of MPD reports . In an effort to distance itself from the increasing skepticism regarding the clinical validity of MPD, the organization dropped "multiple personality" from its official name in 1993, and then in 1997 changed its name again to the International Society for the Study of Trauma and Dissociation . </P> <P> 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, but the condition retains an inherent subjectivity due to difficulty in defining terms such as personality, identity, ego - state and even amnesia . The ICD - 10 still classifies DID as a "Dissociative (conversion) disorder" and retains the name "multiple personality disorder" with the classification number of F44. 8.81 . </P> <P> A 2006 study compared scholarly research and publications on DID and dissociative amnesia to other mental health conditions, such as anorexia nervosa, alcohol abuse and schizophrenia from 1984 to 2003 . The results were found to be unusually distributed, with a very low level of publications in the 1980s followed by a significant rise that peaked in the mid-1990s and subsequently rapidly declined in the decade following . Compared to 25 other diagnosis, the mid-90's "bubble" of publications regarding DID was unique . In the opinion of the authors of the review, the publication results suggest a period of "fashion" that waned, and that the two diagnoses "(did) not command widespread scientific acceptance". </P>
