Which disorders are included in Cluster A?

The disorders that are classified as Cluster A in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) are characterized by odd or eccentric behaviors. This cluster includes Paranoid Personality Disorder and Schizoid Personality Disorder, which fits the characteristics of this cluster.

Paranoid Personality Disorder involves pervasive distrust and suspicion of others, leading individuals to interpret the motivations of others as malevolent. Schizoid Personality Disorder is marked by a pattern of detachment from social relationships and a restricted range of emotional expression. Both disorders reflect the odd or eccentric features that are essential to Cluster A disorders, making them the correct identifiers for this classification.

The other options involve disorders from different clusters: Antisocial and Borderline Personality Disorders belong to Cluster B, which is characterized by dramatic, emotional, or erratic behaviors. Avoidant and Dependent Personality Disorders, on the other hand, are associated with anxious and fearful behaviors and fall under Cluster C. The inclusion of Obsessive-Compulsive and Histrionic Personality Disorders also pertains to Cluster B, linking them to those who exhibit dramatic traits. Hence, the understanding of these clusters helps clarify how different disorders are grouped based on shared features and behaviors.
