Exposure and response prevention (ERP) is a specific type of cognitive behavioral therapy for OCD. With a trained therapist, you gradually face the thoughts and situations that trigger your obsessions while choosing not to do the compulsion. The National Institute of Mental Health reports that ERP effectively reduces compulsive behaviors.
Key takeaways
- OCD involves unwanted, recurring thoughts (obsessions), repetitive behaviors (compulsions), or both, and it often takes up more than an hour a day.
- Exposure and response prevention (ERP) is the type of cognitive behavioral therapy (CBT) most closely tied to OCD treatment.
- ERP is gradual and planned. You start with situations you can handle and build from there, with a therapist guiding the plan.
- General supportive talk therapy is not the same as ERP. Ask any counselor you see about their ERP training.
- Only a qualified health care provider or mental health professional can diagnose OCD, and medication questions belong with your physician.
What is OCD?
The National Institute of Mental Health (NIMH) describes obsessive compulsive disorder (OCD) as "a disorder marked by uncontrollable and recurring thoughts (obsessions), repetitive and excessive behaviors (compulsions), or both." NIMH notes that symptoms "usually start between late childhood and young adulthood," though they can begin at any time.
Common examples NIMH lists include a fear of germs or contamination, a fear of losing control over your own behavior, excessive cleaning or handwashing, and repeatedly checking that the door is locked or the oven is off. In its OCD guide, NIMH adds that people with OCD often "spend more than 1 hour a day on their obsessions or compulsions."
Everyone double checks a lock now and then. What sets OCD apart is the loop: an intrusive thought creates anxiety, a compulsion brings brief relief, and the relief teaches your brain to reach for the compulsion again next time.
What is exposure and response prevention (ERP)?
The International OCD Foundation (IOCDF) puts it plainly: "The most important type of CBT for OCD is exposure and response prevention (ERP)." ERP has two parts that work together:
- Exposure means practicing confronting the thoughts, images, objects, and situations that make you anxious, per the IOCDF.
- Response prevention, in the IOCDF's words, "refers to making a choice not to do a compulsive behavior once the anxiety or obsessions have been triggered."
The goal is not to force yourself to feel calm. It is to learn, through experience, that you can sit with uncertainty and discomfort without the compulsion, and that the anxiety tends to ease on its own.
How does ERP work, step by step?
NIMH describes ERP as time spent "in a safe environment that gradually exposes them to situations that trigger their obsession and prevent them from engaging in their typical compulsive behavior (such as handwashing)." In practice, the work usually follows a pattern like this:
- Map the cycle. You and your therapist name your obsessions, the compulsions that follow, and the situations that set them off.
- Build a plan. Together you list feared situations from easier to harder. The IOCDF notes that a trained clinician works with you to develop a plan for exposure.
- Start small. You face an easier situation first, such as touching a doorknob without washing right away.
- Resist the compulsion. You stay with the discomfort instead of checking, washing, or seeking reassurance.
- Practice and build. You repeat exposures between sessions and move up the list over time. According to the IOCDF, you "will eventually learn to do your own ERP exercises to help manage your symptoms."
The Mayo Clinic describes the same idea: exposing you over time to a feared object or obsession, then learning ways not to do your compulsive rituals.
Does ERP work?
NIMH states: "Research shows that ERP, a specific type of CBT, effectively reduces compulsive behaviors, even for people who do not respond well to medication." NIMH also notes that ERP can raise anxiety at first, and that compulsions usually decrease as treatment continues.
It is honest work, and it is hard work. The Mayo Clinic notes that "ERP takes effort and practice," and that OCD treatment may not result in a cure. Many people find that ERP helps them spend less time stuck in the loop and more time on the life they want.
Is ERP different from regular talk therapy?
Yes. ERP is a structured, skills based form of CBT, not open ended conversation. The IOCDF cautions that while talk therapy can be "a very valuable treatment for some disorders," there is no research evidence that general talk therapy is effective in treating OCD. It points to ERP and medication as the treatments shown through extensive research to be the most effective.
That is why it matters to ask any counselor directly about their ERP training and experience. Some people with OCD also notice that general reassurance, from a friend or a therapist, can quietly become another compulsion.
What about medication for OCD?
NIMH notes that "mental health professionals treat OCD with medications, psychotherapy, or a combination of treatments," and that the most common medications prescribed for OCD are antidepressants that target serotonin. Whether medication is right for you is a decision for you and your physician or psychiatrist. Foundations counselors provide talk therapy and do not prescribe or advise on medication. If you already take medication, NIMH advises: "Do not stop taking your medication without first talking to your health care provider."
Who diagnoses OCD?
Diagnosis is a clinician's call, not something a checklist or an article can settle. NIMH notes that OCD can be hard to diagnose because its symptoms can look like other conditions, and it recommends you "speak with a health care provider" first. A provider can check for other causes and refer you to a mental health professional for further evaluation or treatment. If you have many of the symptoms above, that is a good reason to ask, not a diagnosis.
What should parents know about OCD in children?
NIMH points out that "children may not realize that their behavior is out of the ordinary," and that children with OCD may need additional help from family members and health care providers. Parents are often the first to notice rituals, repeated questions, or long routines around bedtime, washing, or checking. NIMH's advice is direct: "If you think you or your child may have OCD, talk to a health care provider."
At Foundations, child and teen counseling is available, and the ages each counselor sees vary by counselor.
How can counseling at Foundations help with OCD?

Frequently asked questions
What is exposure and response prevention therapy?
Exposure and response prevention (ERP) is a specific type of cognitive behavioral therapy for OCD. You gradually face the thoughts and situations that trigger your obsessions, with a therapist guiding the plan, and practice choosing not to do the compulsion. Over time, the anxiety tends to ease without the ritual.
Is ERP effective for OCD?
The National Institute of Mental Health reports that research shows ERP effectively reduces compulsive behaviors, even for people who do not respond well to medication. ERP takes effort and practice, and anxiety can rise at first. Results vary from person to person, and treatment may not result in a cure.
How is ERP different from regular talk therapy?
ERP is a structured, skills based form of CBT built around planned exposures and resisting compulsions. General supportive talk therapy is different, and the International OCD Foundation says there is no research evidence that it is effective in treating OCD. Ask any counselor about their ERP training.
Do Foundations counselors offer ERP?
Fifteen Foundations counselors list OCD on their profiles, and some list exposure therapy among their approaches. Because ERP is a specialized skill, ask your matched counselor about their ERP training and experience. Your first meeting with that counselor is a free consultation, which is a good time to ask.
Do I need medication for OCD?
That is a question for your physician or a psychiatrist, not your counselor. NIMH notes that OCD is treated with medication, psychotherapy, or a combination. Foundations counselors provide talk therapy and do not prescribe or advise on medication. Do not stop any medication without first talking to your health care provider.
How do I know if I or my child has OCD?
Only a qualified health care provider or mental health professional can diagnose OCD. NIMH recommends talking to a health care provider if you think you or your child may have OCD. Signs include unwanted, recurring thoughts and repetitive behaviors that take up more than an hour a day or interfere with daily life.
