Which cluster is the anxious or fearful cluster that includes avoidant, dependent, and obsessive-compulsive personality disorders?

• A. Cluster A
• B. Cluster B
• C. Cluster C
• D. Delusion

Answer: (C)

Anxious or fearful tendencies group together as the cluster that includes avoidant, dependent, and obsessive-compulsive personality disorders. This cluster is defined by chronic anxiety and fearfulness in social situations and relationships, along with a need for order, reassurance, or control. That shared pattern is what ties these disorders together and sets them apart from the other clusters. The other clusters describe different personality patterns: one clusters together odd or eccentric behaviors, and another clusters together dramatic, emotional, or erratic behaviors. A delusion isn’t a cluster of personality disorders at all; it’s a symptom that can appear across various conditions.
