Exposure and Response Prevention (ERP) Therapy
When something makes us anxious, our natural instinct is often to avoid it, escape from it, seek reassurance, or find a way to feel safe again. These strategies can bring relief in the moment. But when they become part of an anxiety or OCD cycle, they can unintentionally teach the brain that the feared situation really was dangerous and that you needed to do something to prevent a bad outcome.
Exposure and Response Prevention (ERP) is an evidence-based form of therapy that helps interrupt this cycle. Rather than trying to eliminate anxiety or guarantee that your fears won't happen, ERP helps you gradually learn that you can experience uncomfortable thoughts, feelings, sensations, and uncertainty without relying on avoidance or compulsions.
What Does Exposure and Response Prevention Mean?
ERP has two main components: exposure and response prevention.
Exposure involves intentionally and gradually approaching situations, thoughts, images, sensations, or uncertainties that tend to trigger anxiety.
Response prevention involves practicing a different response instead of engaging in the behaviours you would normally use to reduce your anxiety or gain certainty.
These behaviours might include:
Seeking reassurance
Checking
Avoiding
Googling or researching
Mentally reviewing situations
Trying to "figure out" what a thought means
Repeating or redoing things until they feel right
Checking your feelings or physical sensations
Distracting yourself from uncomfortable thoughts
Trying to replace a "bad" thought with a good one
Over time, ERP helps you learn that anxiety and uncertainty can be experienced without needing to immediately fix, escape or neutralize them.
ERP Isn’t About Throwing You Into Your Biggest Fear
A common misconception about exposure therapy is that you'll be forced to confront something terrifying before you're ready. That's not how we approach ERP.
Exposure work is collaborative, intentional and individualized. Together, we identify the situations, thoughts, or experiences that anxiety has taught you to avoid or control and develop opportunities to practice approaching them differently.
We typically begin with exercises that feel challenging but manageable and build from there. The goal isn't to make you as anxious as possible. The goal is to help you build confidence in your ability to experience anxiety and uncertainty without allowing them to determine what you do next.
What Can ERP Help With?
ERP is most commonly associated with Obsessive-Compulsive Disorder (OCD), but exposure-based strategies can also be helpful for several anxiety-related concerns.
ERP and exposure-based therapy may be used to support:
OCD and intrusive thoughts
Health and illness anxiety
Social anxiety
Specific phobias
Panic and fear of physical sensations
Fear of uncertainty
Avoidance related to anxiety
The specific approach will depend on what you're experiencing and what patterns are keeping the anxiety going.
ERP for OCD & Intrusive Thoughts
With OCD, the "exposure" isn't always something you physically do. Sometimes the feared experience is an intrusive thought, image, feeling, or uncertainty.
For example, OCD might demand answers to questions such as:
What if I hurt someone?
What if I'm secretly a bad person?
What if I'm sick and don't know it yet?
What if I made the wrong decision?
What if I can never be completely certain?
Compulsions may then show up as reassurance seeking, checking, researching, avoidance, and rumination such as reviewing memories, analyzing thoughts, or trying to prove that the feared possibility isn't true.
ERP helps you practice allowing uncertainty to exist without completing the compulsive behaviour that OCD is asking for. Over time, the goal is for the question to become something you no longer believe you need to solve.
What Might ERP Look Like in Therapy?
ERP looks different for every person. Together, we may identify your triggers, fears, avoidance patterns, compulsions, and safety behaviours. We then explore what anxiety is asking you to do and what might happen if you respond differently.
Exposure exercises are developed collaboratively and can happen both during sessions and between sessions.
Depending on your goals, this might involve approaching something you've been avoiding, allowing an intrusive thought to be present without analyzing it, reducing reassurance seeking, intentionally leaving something uncertain, or experiencing a physical sensation without immediately trying to make it stop.
ERP isn't about proving that nothing bad will ever happen. It's about learning that you don't need complete certainty in order to move forward.
ERP goals are specific to the fear and the behaviours that have developed around it. For example, imagine someone experiencing health anxiety notices an unfamiliar sensation in their body. Their usual pattern might be:
Trigger: Notice a new physical sensation
Fear: What if this is a sign of something serious?
Compulsion: Google the symptom, check their body repeatedly or ask someone for reassurance
Short-term result: Anxiety decreases temporarily
Long-term result: The brain learns that the sensation needed to be investigated in order to feel safe
An ERP goal might be:
Exposure: Notice the sensation and allow the possibility of uncertainty about what it means.
Response Prevention: Refrain from Googling the symptom, repeatedly checking the body or asking others for reassurance.
Instead of trying to reach the conclusion "I'm definitely healthy," the person practices making room for uncertainty:
"I notice that my mind wants an answer right now. I may not be able to know with complete certainty, and I can continue with my day without solving this."
The goal isn't to prove that the feared outcome won't happen. The goal is to practice not allowing the need for certainty to determine what happens next.
Another example might involve social anxiety. Someone may fear saying something awkward during a conversation and cope by rehearsing sentences in their head, staying quiet, or reviewing the conversation afterward.
An exposure could involve intentionally participating in a conversation without carefully rehearsing what to say. The response prevention could be allowing the interaction to be imperfect and resisting the urge to replay it afterward to determine whether they "did okay."
Over time, these experiences help build greater confidence in your ability to tolerate uncertainty, discomfort, and imperfection.
Making more Room for the Life You Want
Anxiety and OCD can slowly create rules around your life:
Don't go there.
Check one more time.
Make sure you're certain.
Ask someone what they think.
Figure this out before you move on.
ERP helps you begin challenging those rules. As you practice approaching rather than avoiding and responding differently to anxiety, there can be more room for the things that matter to you - your relationships, work, parenting, interests, values, and everyday life.
