What is another name for dissociative identity disorder?

Dissociative identity disorder (DID), formerly known as multiple personality disorder, is characterized by the presence of two or more distinct personality states, each with its own sense of self and behavior patterns. The name "multiple personality disorder" was used historically and emphasizes the existence of these distinct identities as separate entities within the individual. Although the terminology has shifted to dissociative identity disorder to more accurately reflect the nature of the condition and its relationships with dissociative processes, the public and some literature still reference it as multiple personality disorder due to its historical context. The change in nomenclature helps to highlight the dissociative symptoms that are central to the disorder, rather than just focusing on the multiplicity of personalities.

In contrast, the other terms presented do not accurately represent dissociative identity disorder. "Personality disorder" is a broader category that includes various disorders characterized by enduring patterns of behavior, thoughts, and emotions. "Borderline personality disorder" specifically refers to a different condition characterized by instability in interpersonal relationships, self-image, and emotions. "Severe identity disorder" is not a recognized term in psychiatric classifications. Therefore, multiple personality disorder remains a closely associated identity for dissociative identity disorder, reflecting its historical roots.
