Some people get stuck in a vicious cycle: Certain situations or intrusive thoughts spark obsessive thinking, which fuels anxiety or distress — often physical as well as psychological. To relieve that discomfort, a person may engage in compulsive behaviors, which bring short-term relief but reinforce the cycle over time. Exposure and response prevention (ERP) therapy is a research-backed way to break that cycle.

ERP is the gold-standard treatment for OCD. It's a specialized form of exposure therapy — the broader family of exposure-based approaches also treats specific phobias, panic, and other anxiety disorders — but ERP's defining response-prevention component makes it especially suited to conditions maintained by compulsions or rituals, such as OCD and related disorders like body dysmorphic disorder and health anxiety. That makes it a worthwhile methodology to incorporate into your treatment plans, particularly if you are drafting one for a client living with OCD. 

Not sure where to start? Here are the basics of exposure and response prevention therapy.

Key insights

1

Exposure and response prevention (ERP), a gold-standard treatment for OCD, is all about breaking the link between specific triggers, the obsessive thoughts they provoke, and the compulsive behaviors used to relieve the resulting anxiety.

2

An ERP therapist helps their client gradually confront those triggers while resisting the urge to lapse into compulsive behaviors, eventually making the feared situations feel more tolerable to face.

What is ERP?

ERP is a specialized form of cognitive behavioral therapy (CBT). Over its decades of use, it has proven to be a highly successful OCD treatment. A client going through ERP practices confronting the thoughts, situations, actions, or images that trigger their obsessions — and the anxiety those obsessions bring — while deliberately resisting the urge to perform their usual compulsions, for example, choosing not to wash their hands after touching a public doorknob. Over time, the anxiety attached to these triggers fades, and the person learns they can tolerate the discomfort without performing the compulsion

Although ERP is a form of CBT, it has some key differences from classic CBT. Its goal is to decouple thoughts from compulsive behaviors, not necessarily to suppress or “fix” troublesome thought patterns. 

Why is ERP so effective for OCD?

Around 60% of clients with OCD who complete ERP treatment experience significant symptom improvement; in some cases, symptoms may resolve completely. ERP works because it breaks the feedback loop in which an intrusive obsession produces anxiety, and the person tries to relieve that anxiety by performing a compulsion — a response that brings short-term relief but reinforces the cycle over time.

The International OCD Foundation puts it this way: “Imagine what would happen if your fire alarm went off every time you burnt a piece of toast or blew out birthday candles.” Eventually, you’d realize that the alarm goes off even when there’s no imminent danger, and you’d stop panicking each time it does. ERP works similarly, gradually weakening the anxiety that fuels compulsions. This was traditionally described as habituation, though current models emphasize inhibitory learning, in which the client develops new, competing “safety” learning that overrides the original fear.

The core components of ERP

A course of ERP often spans 12 or more sessions, though the length varies with symptom severity and complexity. It typically starts with psychoeducation and assessment of a client's triggers. Then, you’ll help your client practice confronting their triggers without spiraling into compulsive behavior. Afterward, you’ll help them process the experience.

The anxiety hierarchy

Some therapists help their clients create an “exposure hierarchy” to guide treatment. You'll work with your client to define and rank their triggers by how much distress each one provokes, then begin exposure with the lower-distress items and work upward.

To establish an exposure hierarchy, you might start by asking your client to list situations they avoid or that cause distress. For someone who struggles with germ exposure, this list might include touching elevator buttons, riding on public transit, being around someone with a cold, and so on. Once they've listed these situations, you can help your client rank which provoke the most discomfort to create a hierarchy.

Exposure

Exposure is the crux of ERP. In this step, clients come face-to-face with their triggers. Generally, ERP treatment starts with lower-level triggers — those at the bottom of the exposure hierarchy — and works up to bigger ones as clients gain comfort and confidence.

Exposure techniques may include:

  • Imaginal exposure, during which clients envision a feared situation. You might guide them to write out a description of the event then read it aloud, or just to describe it in detail.
  • In vivo exposure, or real-life exposure. A client afraid of germs, for example, might practice touching a doorknob in a public space.

Response prevention

Facing fears is only half the battle. To truly retrain the brain, clients also have to resist the urge to self-soothe with compulsive behaviors — for example, not washing their hands immediately after touching the doorknob. 

Techniques that may help reinforce response prevention include:

  • Delaying the compulsion (like hand washing) for a set amount of time.
  • Mindfulness exercises, so the client stays grounded in the present moment to lessen rumination or spiraling.
  • Defusion exercises, which may make the anxiety and obsessive thoughts feel less pressing. For example, you might help your client practice thinking, “I really want to wash my hands because I touched a doorknob, but I am choosing not to.”

CBT & ERP

ERP is a form of CBT, but it works a bit differently — traditional CBT practitioners can pick it up readily with a few key shifts in approach.

Traditional CBT, an evidence-backed treatment for diagnoses including depression and anxiety, works by targeting the interplay between thoughts, feelings, and behaviors — often by identifying and shifting distorted thought patterns that drive unhelpful emotions and actions. ERP, by contrast, is about breaking the cycle linking obsessive thoughts, the anxiety they produce, and the compulsive actions that follow. ERP practitioners aren't necessarily trying to 'fix' or suppress problematic thought patterns, but to help their clients break free of the compulsions that anxiety drives them toward.

While that may seem like a small distinction, it's an important one. The thought-shifting piece of traditional CBT — cognitive therapy, which helps people gather evidence for or against their thoughts — can backfire when applied to OCD without proper adaptation, according to the International OCD Foundation. A cognitive therapist might tell a germ-fearing patient that they're highly unlikely to get sick after touching elevator buttons — but many people with OCD already know this rationally, and are simply unable to overcome the intrusive thought without resorting to compulsive behaviors regardless. For OCD, that kind of reasoning can function as its own compulsion: it mimics reassurance-seeking, brings the same short-term relief, and feeds the same obsession-anxiety-compulsion loop that ERP is designed to break.

Tips for implementing ERP techniques in your practice

Want to start using ERP in your practice? Consider these points before you get started.

Session structure and planning

You can't jump straight into ERP. It's important to do prep work, as well as post-exposure processing work, to avoid unnecessary distress for your clients. This progression will likely include: 

  • Psychoeducation, so your client understands what the ERP process will entail and why it may be helpful
  • Defining fears and exposure progression, as through the exposure hierarchy exercise
  • Gradual exposure, perhaps starting with imaginal exposure before working up to in vivo
  • Response prevention, guiding the client to resist or delay their usual compulsions during and after exposure
  • Post-exposure processing to discuss how the exposure felt and how to move forward

 Documentation and compliance considerations

As a first-line treatment for OCD, as well as an accepted treatment for other mental health conditions, ERP therapy should be covered for clients with relevant diagnoses. Laying out a comprehensive narrative through your documentation should help you stay compliant as you move through treatment. Remember, you should create a “golden thread,” tying together different pieces of documentation including:

  • A client’s intake note
  • Your treatment plan
  • Post-session progress notes 

Headway is here to help, offering rapid credentialing services, documentation templates, and billing and claims support so you can focus on providing great care. 

What are criticisms of ERP?

Clients and therapists alike may resist ERP because it can be distressing for patients, many of whom have spent years avoiding their stressors. ERP has relatively high patient drop-out rates because of its inherent discomfort, and some clinicians are hesitant to use it among children and adolescents for the same reason. While ERP — like any form of therapy — does not work for everyone, it is still considered an effective treatment for OCD, and its drawbacks can be managed with proper planning, guidance, and psychoeducation.
