Dissociative Identity Disorder was previously known as what?

Dissociative Identity Disorder (DID) was previously referred to as Multiple Personality Disorder. This terminology was commonly used before it was changed in the Diagnostic and Statistical Manual of Mental Disorders (DSM) to better describe the clinical features of the condition. The term "multiple personality" suggested that an individual had two or more distinct personalities, which could mislead the understanding of the disorder's actual nature.

The change to Dissociative Identity Disorder reflects the complexity of the symptoms wherein a person may experience a fragmented sense of identity. The term "dissociative" highlights how individuals may dissociate from their sense of self in response to trauma or stress, leading to distinct identities or personality states. This definition encompasses a broader understanding of the psychological processes involved, focusing on identity fragmentation rather than merely the existence of multiple personalities.

The other options provided do not accurately represent historical or current terminology associated with DID. While memory loss, identity confusion, and severe dissociation are related concepts, they do not encapsulate the official name change or the specifics of the disorder itself.
