Exposure and Response Prevention (ERP)
What Is ERP Therapy and How It Treats OCD and Anxiety Disorders
ERP is the empirically supported treatment for OCD, related disorders, and anxiety disorders. ERP is a behavioral modality within CBT. An exposure is when a client is deliberately exposed to their specific trigger(s), which could be a person, place, object, or situation. The same exposures are repeated at an assigned frequency so that the client can obtain habituation. Researchers within the OCD community use the term habituation, but it can be thought of like ‘desensitization.’
As clients engage in exposures, the perceived threat of their intrusive thoughts reduces, making them feel like they are less anxious, guilty, or disgusted. Exposures aren’t necessarily getting rid of these feelings. Instead, it is increasing the client’s tolerance of anxiety, guilt, and disgust.
Exposure and Response Prevention: Reducing Compulsions and Building Resilience
Exposures are 50% of treatment. The other 50% is the reduction of compulsions. The words ‘compulsions’ and ‘rituals’ have the same meaning and are used interchangeably. The “response prevention” part of ERP is simply ritual reduction.
Clients are taught exactly what compulsions they engage in. Clients are often surprised when they learn that some of their routine behaviors are compulsions. Loved ones are equally surprised when they learn about some of the more subtle, covert compulsions. After a client learns what a compulsion/ritual is, they start to track the more frequent compulsions. Awareness of when compulsions are being completed is essential to reducing them over time.
During the treatment process, the provider begins by creating a list of exposures that are tailored to the client’s specific triggers. The client then rates each exposure based on the level of difficulty they believe it would be to complete the exposure. A hierarchy of exposures is created, and the provider will assign lower-level exposures to be completed first. This allows the client to develop confidence and momentum within the treatment process.
It is not necessary for the clients to begin with easier exposures, but it is the most common and client-preferred way. This also helps minimize the chances of the client talking themselves out of treatment. Like we have said numerous times throughout the literature on this website, OCD is very manipulative.
The exposure the client does with their provider during sessions will also be done daily for homework. Your provider will teach you how to make exposures slightly more difficult or easier if the level of difficulty slightly shifts when you do them at home.
ERP Treatment Process, Habituation, and Long-Term Recovery Success
The repetition of exposures allows the client to experience habituation more swiftly, ultimately making them feel better. When a client is non-compliant, ERP will not work. We will not waste your time and resources. This is why we will always be compassionate and transparent with you.
If the client does not do the exposures as assigned, the chances of them working within a comfortable time frame reduces. If a client comes to their session and says that they did not have time to complete their exposure homework or that they “forgot,” we know that the client is engaging in the avoidance ritual.
It is imperative that the client is completely honest with their provider. We need to know all the details of the intrusive thought. This might seem awkward, silly, embarrassing, or scary depending on the intrusive thought, but we can assure you, we have heard it all.
If you are nervous about engaging in ERP treatment, we understand. The most difficult part of ERP is getting started. As the weeks go on, it gets much easier, and clients become increasingly more confident that exposures work.
We are here to support you and look forward to getting you better.

ERP Therapy: Frequently Asked Questions (FAQ)
About ERP Therapy
What is ERP therapy?
Exposure and Response Prevention (ERP) is a specialized, evidence-based form of cognitive behavioral therapy (CBT) designed to treat OCD and anxiety disorders. ERP helps you gradually face feared thoughts, situations, or sensations while learning to resist compulsive behaviors and avoidance. Over time, this reduces anxiety and helps you regain control.
What conditions does ERP therapy treat?
ERP is most commonly used to treat obsessive-compulsive disorder (OCD), but it is also effective for anxiety disorders such as social anxiety, panic disorder, phobias, health anxiety, and generalized anxiety disorder (GAD). It is especially helpful when anxiety leads to avoidance, compulsions, or repetitive behaviors.
Is ERP the most effective treatment for OCD?
Yes. ERP is widely considered the gold standard treatment for OCD and is recommended by major professional organizations. Research consistently shows it is the most effective therapy for reducing OCD symptoms and improving long-term outcomes.
What to Expect During ERP Therapy
What happens during ERP therapy?
ERP therapy involves identifying triggers, understanding how anxiety and compulsions work, and gradually facing fears in a structured, supportive way. Your therapist will help you practice exposures and develop skills to resist compulsions, reassurance-seeking, and avoidance. Sessions are collaborative and tailored to your comfort level.
Will I be forced to do exposures I’m not ready for?
No. ERP is always collaborative and gradual. You and your therapist decide together which exposures to work on and when. Treatment is paced according to your readiness, and you remain in control throughout the process.
How effective is ERP therapy?
ERP is highly effective. Most people with OCD and anxiety disorders experience significant symptom reduction when working with a trained ERP therapist. Consistent participation and practice help improve results and support long-term progress.
How long does ERP therapy take?
Many people begin to see improvement within 8 to 16 weeks, though treatment length varies based on individual needs, symptom severity, and goals. Some clients continue therapy longer to strengthen progress and prevent relapse.
What should I expect emotionally during ERP therapy?
It is normal to feel increased anxiety during exposures at first. Over time, your brain learns that anxiety naturally decreases without compulsions. This process helps reduce fear and builds confidence in handling uncertainty.
Virtual vs. In-Person ERP Therapy
Is virtual ERP therapy effective?
Yes. Research shows that virtual ERP therapy can be just as effective as in-person treatment. Online therapy also allows you to practice exposures in real-life environments such as your home, workplace, or community.
Session Structure and Scheduling
How long are ERP therapy sessions?
Initial sessions are typically 60 minutes, and follow-up sessions are usually 50 minutes. This provides enough time to review progress, plan exposures, and practice skills.
How often are sessions scheduled?
Most clients begin with weekly sessions. Frequency may be adjusted based on your needs, progress, and treatment goals.
Cost and Insurance
Is ERP therapy covered by insurance?
ERP is a form of cognitive behavioral therapy and is often covered by insurance, though coverage varies by provider and plan. It’s best to contact your insurance company to confirm your benefits.
What does ERP therapy cost?
The first session typically ranges from $200 to $275, and follow-up sessions range from $175 to $250. Documentation may be provided for out-of-network reimbursement when applicable.
Getting Started
Do I need a diagnosis to start ERP therapy?
No formal diagnosis is required to begin ERP therapy. Your therapist can assess your symptoms and determine the most appropriate treatment approach during the initial sessions.
For Parents & Family Members
Supporting an adult child through anxiety or OCD with ERP
Understanding Your Role as a Parent
How can I help my adult child with anxiety or OCD without making it worse?
The most helpful support encourages independence and skill-building rather than avoidance or reassurance. Learning about anxiety and Exposure and Response Prevention (ERP) can help you respond in ways that support long-term recovery instead of unintentionally reinforcing anxiety patterns.
What is the difference between supporting and enabling?
Support helps your adult child face fears and build confidence. Enabling, often unintentionally, involves accommodating anxiety—such as providing repeated reassurance, helping avoid triggers, or taking over responsibilities—which can maintain or worsen symptoms over time.
Is it normal to feel unsure about my role now that my child is an adult?
Yes. Many parents struggle with this transition. Therapy and parent coaching can help clarify healthy boundaries while allowing you to remain supportive and connected.
Family Involvement in ERP Therapy
Can parents be involved in their adult child’s ERP therapy?
With your child’s consent, family involvement can be helpful. This may include educational or coaching sessions that teach you how to respond to anxiety in ways that support treatment progress and reduce unintentional accommodation.
How should I respond when my adult child asks for reassurance?
Reassurance-seeking is common in anxiety and OCD. While it may feel helpful in the moment, repeated reassurance can reinforce anxiety over time. ERP-informed guidance helps parents respond in supportive ways that encourage independence and long-term improvement.
How long does it take to see improvement?
Progress varies for each person. Many individuals begin noticing improvement within a few months, though recovery is not always linear. ERP focuses on building lasting skills and confidence rather than quick, temporary relief.
Boundaries, Independence, and Letting Go
How do I set boundaries without feeling like I’m abandoning my child?
Setting boundaries does not mean withdrawing support. Clear, compassionate limits often help reduce anxiety over time and allow your adult child to develop stronger coping skills and independence.
What if my adult child becomes upset when I stop accommodating their anxiety?
This reaction is common at first. Change can feel uncomfortable, but consistent, supportive boundaries often help reduce anxiety over time. Therapists can guide families through this process while maintaining a healthy relationship.
Is it okay to step back even if my child is struggling?
Yes. Allowing your adult child to experience manageable discomfort is often part of recovery. Staying emotionally supportive while encouraging independence helps build confidence and resilience.
Support for Parents
Should parents seek their own support?
Many parents benefit from their own therapy, parent coaching, or support groups. This can help you manage stress, set healthy boundaries, and better support your child’s recovery.
What if my adult child refuses treatment?
You cannot force an adult into therapy, but you can adjust how you respond to anxiety-related behaviors, set appropriate boundaries, and seek professional guidance to support both yourself and your child.
