Obsessive-Compulsive Personality Disorder Obsessive-Compulsive Personality Disorder (OCPD) is a mental health condition whereby an individual exhibits repeated obsessions, compulsions, or both. The need for complete perfectionism, orderliness, and mental control characterize OCPD. OCPD is divided into clusters A, B, or C depending on the similarity in behavioral patterns. OCPD can significantly interfere with the lives of men, women, and children who have the disease. Symptoms of OCPD can appear in puberty but are more likely to begin during early adulthood. Deviations in patterns of behavior become more visible during adolescence and continue to prevail over long periods. The Diagnostic and Statistical Manual of Mental Disorders (DSM) categorizes OCPD as part of the cluster C of personality disorders
