Which statement correctly identifies DSM-5 Cluster A disorders?

• A. Paranoid, Schizoid, and Schizotypal Personality Disorders are in Cluster A.
• B. Antisocial, Borderline, Histrionic, and Narcissistic Personality Disorders are in Cluster A.
• C. Avoidant, Dependent, and Obsessive-Compulsive Personality Disorders are in Cluster A.
• D. Paranoid Personality Disorder is not part of Cluster A.

Answer: (A)

The key idea is knowing which disorders belong to DSM-5 Cluster A, the odd/eccentric cluster. In DSM-5, Cluster A includes Paranoid Personality Disorder, Schizoid Personality Disorder, and Schizotypal Personality Disorder. So the statement that those three disorders are in Cluster A is correct.

Disorders listed in the other options belong to different clusters: the dramatic/erratic cluster (Cluster B) includes Antisocial, Borderline, Histrionic, and Narcissistic Personality Disorders, while the anxious/fearful cluster (Cluster C) includes Avoidant, Dependent, and Obsessive-Compulsive Personality Disorder. Also, Paranoid Personality Disorder is indeed part of Cluster A, so saying it is not would be incorrect.
