Why has the term "multiple personality disorder" been replaced with "dissociative identity disorder"?

a. The old term was often used to refer to both schizophrenia and DID, thus a new term was needed to end this confusion. b. The word "multiple" suggested the presence of more identities than were commonly observed. c. Fully developed personalities are not present in DID, just varying expressions of different aspects of the patient's personality. d. A new diagnostic term was wanted to remove some of the stigma associated with the old term and its presentation in the media.
