Factors that Differentiate OCD and OCPD

From Psychiatric News Alert: Although obsessive-compulsive disorder (OCD) and obsessive-compulsive personality disorder (OCPD) share some characteristics, a new study indicates they are distinct disorders. Both are impairing disorders marked by compulsive behaviors, but they can be differentiated by the presence of obsessions in OCD and by the capacity to delay reward in OCPD. The study’s senior researcher was H. Blair Simpson, M.D., Ph.D., a professor of psychiatry at Columbia University. The results appear in Biological Psychiatry.

Information about OCD’s description and classification in DSM-5 can be found in the American Psychiatric Publishing book Obsessive-Compulsive Spectrum Disorders: Refining the Research Agenda for DSM-5.

Although individuals with OCPD are often impaired in psychosocial functioning and quality of life, they sometimes also achieve remarkable successes. A prime example is Noah Webster who was  driven by a need for order and who, for 30 years, worked at creating a dictionary of the English language. Read more about him in the Psychiatric News article“Biographer Explores Character, Pathology, and Achievement.”
