Which disorder is commonly known as multiple personality disorder?

• A. Dissociative Identity Disorder
• B. Dissociative Amnesia
• C. Acute Stress Disorder
• D. Posttraumatic Stress Disorder

Answer: (A)

Dissociative Identity Disorder is the condition historically labeled as multiple personality disorder. It involves two or more distinct identity states that alternate control of behavior, along with notable gaps in memory for personal information or events. This pattern of dissociation goes beyond ordinary forgetfulness and causes clear distress or impairment in daily life. Other options don’t fit because dissociative amnesia involves memory gaps without alternate identities; acute stress disorder is an immediate, short-term response after trauma with dissociative symptoms but not multiple identities; posttraumatic stress disorder centers on intrusive memories, avoidance, and arousal over time, not alternating identities.
