Which cluster includes Schizoid, Schizotypal, and Paranoid personality disorders?

• A. Cluster A
• B. Cluster B
• C. Cluster C
• D. Not Assigned

Answer: (A)

Cluster A is the group of personality disorders described as odd or eccentric. It includes schizoid, schizotypal, and paranoid personality disorders. These conditions share a pattern of unusual or detached social behavior and ways of thinking: schizoid and schizotypal tend to involve social withdrawal or discomfort in close relationships, while paranoid involves pervasive distrust and suspicion. This contrasts with Cluster B, which is dramatic or emotional, and Cluster C, which is anxious or fearful. So the cluster that includes schizoid, schizotypal, and paranoid is Cluster A.
