Which disorders are classified as Cluster A personality disorders?

• A. Paranoid, schizoid, and schizotypal
• B. Histrionic, narcissistic, and antisocial
• C. Borderline, antisocial, and dependent
• D. Dependent, avoidant, and obsessive-compulsive

Answer: (A)

Cluster A includes personality disorders that tend to be odd or eccentric in presentation. Paranoid personality disorder involves pervasive distrust and suspicion of others. Schizoid personality disorder shows a pattern of social detachment and limited emotional expression. Schizotypal personality disorder features odd or eccentric thinking and behavior, with discomfort in close relationships and unusual beliefs or perceptual experiences. These share a common theme of social awkwardness and unusual thinking, which is why they fit together as Cluster A. The other groupings reflect different patterns: disorders like histrionic, narcissistic, antisocial, and sometimes borderline are in Cluster B (dramatic/erratic), while dependent, avoidant, and obsessive-compulsive fall into Cluster C (anxious/fearful).
