Which disorder within Cluster B includes a pattern of disregard for and violation of the rights of others, with illegal behavior and lack of remorse?

• A. Borderline
• B. Histrionic
• C. Antisocial
• D. Narcissistic

Answer: (C)

The main idea here is recognizing antisocial personality disorder, which is defined by a long-standing pattern of disregard for and violation of the rights of others, often seen as illegal behavior and a lack of remorse after harming others. This pattern typically includes repeated unlawful acts, deceit, impulsivity, irritability or aggression, Reckless disregard for safety, consistent irresponsibility, and a striking indifference to others’ well-being. It tends to emerge by adolescence with conduct problems and persists into adulthood, with criteria about conduct disorder before age 15 supporting the diagnosis.

This helps distinguish it from other Cluster B disorders. For example, a borderline presentation centers on unstable relationships, emotional volatility, fear of abandonment, and self-harm; histrionic features emphasize excessive attention-seeking and emotional shallowness; narcissistic traits focus on grandiosity and a need for admiration, often with lack of empathy but not an enduring pattern of violating others’ rights and illegal behavior.
