Cluster C Personality Disorders

Cluster C Overview - The Anxious Crew

• Often struggle with interpersonal relationships due to fear of rejection or need for control.
• Includes three main types:
  • Avoidant Personality Disorder (AvPD)
  • Dependent Personality Disorder (DPD)
  • Obsessive-Compulsive Personality Disorder (OCPD) (Not to be confused with OCD)
• 📌 Mnemonic: Anxious Devils Often Cry (Avoidant, Dependent, Obsessive-Compulsive)

⭐ OCPD is ego-syntonic (patients don't perceive their behavior as problematic), unlike OCD which is ego-dystonic (patients are distressed by their symptoms).
