Which cluster is the odd or eccentric cluster that includes paranoid, schizoid, and schizotypal personality disorders?

• A. Cluster A
• B. Cluster B
• C. Cluster C
• D. Cognitive perspective

Answer: (A)

Grouping personality disorders into clusters helps you see patterns in how they present. The odd or eccentric cluster is the one that includes paranoid, schizoid, and schizotypal personality disorders because they share unusual or peculiar patterns of thinking, perception, and social interaction. Paranoid involves pervasive distrust, schizoid shows detachment and limited emotional expression, and schizotypal features odd beliefs or eccentric behavior. This cluster is distinct from the dramatic/erratic cluster (antisocial, borderline, histrionic, narcissistic) and the anxious/fearful cluster (avoidant, dependent, obsessive-compulsive). The cognitive perspective is not a personality-cluster category.
