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

The correct answer is that Paranoid, Schizoid, and Schizotypal Personality Disorders are classified under Cluster A. This cluster is characterized by odd or eccentric behaviors and thought processes.

Individuals with Paranoid Personality Disorder exhibit pervasive distrust and suspiciousness toward others, believing that their motives are malevolent. Schizoid Personality Disorder is characterized by a pattern of detachment from social relationships and a restricted range of emotional expression. Schizotypal Personality Disorder involves acute discomfort in close relationships, cognitive or perceptual distortions, and eccentric behavior.

This classification in Cluster A distinguishes these disorders from those in Cluster B, which includes dramatic, emotional, or erratic disorders such as Antisocial, Borderline, Histrionic, and Narcissistic Personality Disorders, and Cluster C, which comprises anxious and fearful disorders, such as Avoidant, Dependent, and Obsessive-Compulsive Personality Disorders.

Understanding the characteristics of these clusters helps in identifying the nature and patterns of behavior associated with different personality disorders, which is crucial for effective diagnosis and treatment.
