Which cluster includes paranoid, schizoid, and schizotypal personality disorders?

• A. Cluster A
• B. Cluster B
• C. Cluster C
• D. None

Answer: (A)

Cluster A consists of paranoid, schizoid, and schizotypal personality disorders. These conditions share a pattern of odd or eccentric ways of thinking and relating to others. Paranoid personality disorder is marked by pervasive mistrust and suspicion of others’ motives. Schizoid personality disorder involves social detachment and a limited range of emotional expression. Schizotypal personality disorder includes odd beliefs or magical thinking, unusual perceptual experiences, and discomfort in close relationships. Because they all center on these characteristic odd/eccentric patterns, they are grouped together as Cluster A. The other clusters are different in their predominant patterns: Cluster B covers dramatic, erratic behaviors, and Cluster C covers anxious or fearful patterns.
