Dissociative identity disorder (DID) is a psychiatric condition that was formerly known as multiple personality disorder (MPD). DID is viewed as the most complex and severe of the dissociative disorders, a category that also includes dissociative amnesia, dissociative fugue, and depersonalization disorder (see Cardeña & Gleaves, 2007 for a discussion of other dissociative disorders). Although it is controversial and long regarded as exotic and rare, a wealth of research has been conducted on DID in recent years, particularly since the 1980s.
