Question 2 of 5
A 22-year-old client presents with a diagnosis of antisocial personality disorder and a history of using drugs, writing numerous checks with insufficient funds, and stealing. He appears charming and intelligent, and the other clients are impressed and want to be liked by him. The greatest problem that may arise from this situation is that:
Correct Answer: A
Rationale: This answer is correct. Persons with antisocial personality disorder typically are very manipulative. This answer is incorrect. The client's behavior cannot cause another person to become psychotic. This answer is incorrect. Psychosis is not a symptom of antisocial personality. One of the criteria for diagnosis of this disorder is that no psychosis be present. In addition, the client would love the attention. This answer is incorrect. Self-mutilative behavior is characteristic of the borderline personality disorder.
