There are ten personality disorder types, broken down into three categories: Cluster A, Cluster B, and Cluster C. AVPD belongs to a group of personality disorders characterized by fear or anxiousness -- Cluster C. Also included in Cluster C are obsessive-compulsive disorder (OCPD) and dependent personality disorder (DPD). Psychiatric experts associate AVPD more closely with DPD than with other Cluster C disorders. Individuals with DPD also experience feelings of worthlessness, but seek out a caregiver to fulfill their needs.
