Mental health care providers use the manual known as the DSM-5 to guide their diagnoses. This book is published and frequently updated by the American Psychiatric Association (APA). It contains information on symptoms, risk factors, diagnostic criteria, and more about all known mental health conditions.
The DSM-5 classifies OCD and OCPD differently, despite their similar names. While the classifications may seem meaningless at first, they help providers and patients alike understand these conditions.
What is OCD?
OCD is a mental health disorder characterized by obsessive thoughts and compulsive behaviors. Importantly, these intrusive thoughts and rituals make the patient feel distressed. This disorder can affect people across demographics
Until recently, the DSM-5 classified OCD under the umbrella of “anxiety disorders.” However, more research has shown that it is unlike any other anxiety disorder in many ways, so the APA moved it into a category of its own.
Obsessive thoughts are a hallmark of OCD. People with OCD have these thoughts about a variety of subjects. What distresses one person may not affect another. Obsessive thoughts may include:
- Fear of germs, dirt, or other contamination
- Unwanted intrusive thoughts, including those involving aggression, sex, or religion
- Intense stress when things aren’t where the patient believes they should be
- Trouble accepting uncertainty
- Unwanted thoughts about acting inappropriately or dangerously
People with OCD experience compulsions that are usually related to their obsessive thoughts. The compulsions lead people with OCD to perform rituals in hopes of relieving the anxiety from the obsessive thoughts. People with OCD feel compelled to complete these rituals, even if it negatively impacts their lives.
What is OCPD?
OCPD is a personality disorder that causes people to need rigid rules, order, and control over all situations. People with this disorder often feel righteous for doing everything the “right way,” and expect others to adhere to their strict standards.
As the name suggests, the DSM-5 classifies OCPD under the category of personality disorders. This umbrella term includes three subcategories: suspicious, emotional/impulsive, and anxious personality disorders. OCPD falls into the anxious subcategory alongside avoidant personality disorder and dependent personality disorder.
People with OCPD may:
- Work to the point of ignoring social and family obligations
- Exhibit hoarding behaviors
- Fixate on rules, lists, and small details
- Not give generously or spend frivolously, even when they can
- Have such perfectionistic tendencies that it’s hard to complete tasks
- Follow a rigid set of values and morals
- Not delegate tasks unless someone completes the task exactly “right”
Unlike OCD, OCPD does not include a pattern of intrusive obsessions that lead to specific compulsions. Instead, the symptoms of OCPD tend to affect every aspect of the individual’s personality.
