The names are confusingly similar, and people often mix them up. But obsessive-compulsive disorder (OCD) and obsessive-compulsive personality disorder (OCPD) are different conditions, with different experiences and treatments.
The key differences
| OCD | OCPD | |
|---|---|---|
| What it is | Unwanted intrusive thoughts (obsessions) and rituals (compulsions) | A lasting personality pattern of perfectionism, order and control |
| How it feels to the person | Distressing, unwanted, “not me” | Often feels right and reasonable |
| What drives it | Anxiety and a need to prevent harm or feel “just right” | High standards, rules and a need for control |
| Focus | Specific fears, like contamination, harm or doubt | Work, rules, details, schedules and how things “should” be done |
| Insight | Usually knows the thoughts are excessive | Often sees others as the problem |
| Main treatment | ERP (exposure and response prevention) and SSRIs | Psychotherapy, such as CBT |
What is OCD?
OCD involves unwanted, intrusive thoughts, images or urges that cause distress, and compulsions, physical or mental, done to relieve it. People with OCD usually wish the thoughts would go away. Our post on what OCD is and what causes it explains more.
What is OCPD?
OCPD is a personality disorder: a lasting pattern, usually starting by early adulthood, of preoccupation with order, perfectionism and control, at the expense of flexibility, openness and efficiency. Signs can include:
- being so focused on details, rules, lists or schedules that the main point gets lost
- perfectionism that gets in the way of finishing tasks
- devotion to work at the expense of friendships and leisure
- rigid views about morals, ethics or values
- difficulty throwing out worn-out or worthless objects
- reluctance to delegate unless things are done exactly your way
- being careful with money, and stiffness or stubbornness
People with OCPD often see their standards as correct and may feel frustrated when others don’t meet them. Family, colleagues or partners are often the ones who notice the difficulties first.
Can you have both?
Yes. Some people have both OCD and OCPD. They’re separate conditions, but they can overlap, and having traits of one doesn’t mean you have the other.
How each is treated
- OCD: exposure and response prevention (ERP), a form of CBT, and SSRI medicine are the most effective treatments.
- OCPD: psychotherapy is the main treatment, often CBT or other talking therapies that help with flexibility, perfectionism and relationships. Medicine may help with anxiety or depression alongside it.
When to get help
Talk to a doctor or therapist if intrusive thoughts and compulsions, or rigid perfectionism and control, are causing distress or affecting your work, relationships or wellbeing. A professional can work out which, if either, applies to you.

Frequently asked questions
Is OCPD worse than OCD?
Neither is “worse”. They affect people differently. OCD often causes intense distress from intrusive thoughts. OCPD can cause problems in relationships and work because of rigidity. Both are treatable.
How do I know if I have OCD or OCPD?
Ask how the thoughts and behaviours feel. If they feel unwanted and anxiety-driven, and you wish they’d stop, that points to OCD. If you feel your standards are right and others are the problem, that points more to OCPD. A professional can assess you properly.
Is being a perfectionist the same as OCPD?
No. Many people are perfectionists without having OCPD. OCPD is a pervasive pattern that causes real problems in work, relationships or daily life.
Can OCPD be treated?
Yes. Talking therapy can help people with OCPD become more flexible, reduce perfectionism and improve relationships.
