A college student observes a roommate going out wearing uncharacteristically seductive clothing, returning 12 to 24 hours later, and then sleeping for 8 to 12 hours. At other times, the roommate sits on the floor speaking like a young child. Which health problem should be considered?
Correct Answer: B
Rationale: The correct answer is B: Dissociative identity disorder. The roommate displaying different behaviors indicates potential dissociation, where different identities or states of consciousness take control. Seductive clothing and extended absence may indicate a different identity, while childlike speech may suggest another identity. This pattern aligns with the criteria for dissociative identity disorder. Functional neurological disorder (Choice A) involves physical symptoms without a clear organic cause. Dissociative amnesia (Choice C) pertains to memory loss due to psychological trauma. Body dysmorphic disorder (Choice D) involves obsession with perceived flaws in physical appearance. These options do not align with the diverse behaviors and identity shifts observed in the roommate.
