Which cluster of personality disorders includes obsessive-compulsive, avoidant, and dependent types?

• A. Cluster C
• B. Cluster A
• C. Cluster B
• D. Not a Cluster

Answer: (A)

The cluster described as anxious and fearful groups together personality disorders that tend to involve worry, fear of criticism or rejection, and a need for control or perfection. Obsessive-compulsive personality disorder, avoidant personality disorder, and dependent personality disorder all fit this pattern, so they belong to the same cluster. It’s also important to distinguish obsessive-compulsive personality disorder from obsessive-compulsive disorder, which is an anxiety disorder, not a personality disorder. So, the cluster that includes obsessive-compulsive, avoidant, and dependent types is the anxious-fearful cluster.
