Which cluster includes Paranoid, Schizoid, and Schizotypal Personality Disorders?

The personality disorders that fall under Cluster A are characterized by odd or eccentric behaviors and thoughts. This cluster includes Paranoid Personality Disorder, which involves a pervasive distrust and suspicion of others; Schizoid Personality Disorder, which is marked by a lack of interest in social relationships and a restricted range of emotional expression; and Schizotypal Personality Disorder, which features discomfort in close relationships, cognitive or perceptual distortions, and eccentric behavior.

Cluster A is specifically distinguished from Clusters B and C, which include personality disorders with different characteristics. Cluster B encompasses disorders that are dramatic, emotional, or erratic (such as Borderline Personality Disorder and Narcissistic Personality Disorder), while Cluster C includes disorders that involve anxious and fearful behaviors (like Avoidant Personality Disorder and Obsessive-Compulsive Personality Disorder).

Thus, the inclusion of Paranoid, Schizoid, and Schizotypal Personality Disorders in Cluster A is correct as they share the common theme of eccentricity or oddness in their presentation.
