What Are Cluster C Personality Disorders?

Cluster C personality disorders are a group of mental health conditions characterized by anxious and fearful patterns of thinking, feeling, and behaving. These disorders are classified within Cluster C in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). There are three main types of Cluster C personality disorders:

• Avoidant Personality Disorder (AVPD): Individuals with AVPD experience a pervasive pattern of social inhibition, feelings of inadequacy, and hypersensitivity to criticism or rejection. They often fear being humiliated or embarrassed, leading to avoidance of social situations and difficulties in forming and maintaining relationships.
• Dependent Personality Disorder (DPD): People with DPD exhibit an excessive need to be cared for by others. They have an overwhelming fear of separation and struggle to decide or take responsibility independently. They may go to great lengths to gain and maintain support from others, even if it means enduring mistreatment or being in dysfunctional relationships.
• Obsessive-Compulsive Personality Disorder (OCPD): OCPD is characterized by a preoccupation with orderliness, perfectionism, and control. Individuals with OCPD have a rigid adherence to rules, an excessive focus on details, and a tendency to prioritize work or productivity over interpersonal relationships. They may have difficulty relaxing or delegating tasks and often struggle with flexibility and spontaneity.

Cluster C personality disorders typically manifest in early adulthood and can cause significant distress and impairment in various areas of life. While the exact causes are not fully understood, a combination of genetic, environmental, and psychological factors is believed to contribute to their development.

Treatment for Cluster C personality disorders often involves a combination of psychotherapy, such as cognitive-behavioral therapy, and medication to alleviate symptoms, improve coping skills, and enhance overall functioning.
