Which cluster would include antisocial, histrionic, narcissistic, and borderline personality disorders?

• A. Cluster A
• B. Cluster B
• C. Cluster C
• D. Delusion

Answer: (B)

Grouping personality disorders by clusters based on similar patterns of behavior helps organize how these conditions relate to each other. Antisocial, histrionic, narcissistic, and borderline all share a dramatic, emotional, and unstable way of relating to others and managing self-image. That combination fits together in the dramatic-emotional-erratic group, which is commonly labeled as Cluster B in the DSM-5. Understanding these traits together clarifies why they’re grouped: antisocial actions often involve disregard for norms and others’ rights, borderline features include intense, unstable relationships and self-image, histrionic traits revolve around attention-seeking, and narcissistic traits involve grandiosity and a need for admiration. In contrast, Cluster A captures odd or eccentric patterns (paranoid, schizoid, schizotypal), Cluster C covers anxious and fearful styles (avoidant, dependent, obsessive-compulsive), and delusion is not a personality-cluster label but a symptom that can appear across disorders.
