Exposure and response prevention (ERP)

ERP therapy is a well-established, evidence-based approach that helps people change how they respond to anxiety or fear. It’s often an option recommended when patterns of avoidance or repetitive behaviours feel hard to step away from, such as with obsessive-compulsive disorder (OCD).

But what does it actually involve, and how do you know if it might suit you?

What is ERP therapy?

Exposure and response prevention (ERP) is a specialised form of cognitive behavioural therapy (CBT). At the heart of ERP are two main areas of focus:

• Exposure: Gradually facing situations, thoughts, or feelings that trigger anxiety.
• Response prevention: Choosing not to carry out behaviours that reduce anxiety in the short term (e.g. checking, reassurance seeking, avoidance, or repetitive actions). 

Rather than trying to get rid of anxious thoughts, ERP helps you build confidence in your ability to experience them without needing to respond in the same way you have before.

How does ERP work?

It’s understandable to want quick relief when anxiety shows up, but over time, habits like avoidance or repetition can actually keep the anxiety cycle going. ERP is based on the idea that anxiety naturally rises and falls on its own, even without you having to do anything to reduce it. 

ERP therapy works by breaking the link between frightening thoughts, images, sensations, feelings, urges, or objects, and the actions used to reduce anxiety.

With the right support, you can begin to:

• face situations or thoughts you would usually avoid
• sit with the discomfort rather than trying to reduce it straight away
• notice that anxiety reduces on its own.

ERP psychology is often structured around three key ideas:

1. Gradual exposure

You don’t start by facing your biggest fears. Instead, you create a list of triggers and work your way up. This means you begin with fears that feel more manageable and build up to ones that might not feel possible at the moment. 

2. Response prevention

You practise choosing not to engage in behaviours that normally bring short-term relief from anxiety. This allows you to see what happens to your anxiety when you simply sit with it rather than trying to get rid of it. 

3. Repetition and practice

ERP works best with regular practice, both in therapy sessions and in everyday life. Practising outside of sessions can often help you make steadier progress. Over time, by facing fears without relying on your usual safety behaviours (such as checking or reassurance seeking), you may begin to notice:

• Your feared outcome is often less likely to occur than it feels in the moment.
• You don’t need to rely on certain routines or rituals to cope with anxiety.
• Anxiety may feel uncomfortable, but it can be tolerated. 

What issues can exposure therapy help with?

ERP therapy is widely used for a range of anxiety-related issues, including:

• obsessive-compulsive disorder (ERP is often considered the first-line approach for OCD treatment)
• phobias
• panic and social anxiety
• general anxiety and worry
• hoarding or difficulty discarding items
• body dysmorphic disorder (BDD) and body-focused concerns (such as repeated checking)
• health-related anxiety (such as frequent reassurance seeking)

It can also be adapted to other challenges in which avoidance and repetitive behaviours play a role. 

What happens in an ERP therapy session?

ERP is a collaborative process and tailored to your needs and goals. While approaches may vary, sessions often include:

Assessment and planning

With a therapist, you explore your experiences, including triggers and patterns, and begin creating a gradual exposure plan together. 

Building an exposure plan

This typically involves creating an exposure ‘hierarchy’ – a list of situations ranked from least to most anxiety-provoking, helping the process feel more structured and easier to handle. 

Carrying out exposures

With guidance, you begin to face selected situations or thoughts, starting at a level that feels challenging yet still manageable. 

Practising response prevention

This frequently involves sitting with anxiety without carrying out your usual responses to ease the difficult feelings. While this may feel uncomfortable at first, it’s often where the key learning happens. Over time, you may notice that your urge to rely on rituals begins to shift. 

Repeating and building confidence

With practice, many people notice:

• anxiety doesn’t rise as high as they expected
• anxiety passes more quickly
• situations and triggers begin to feel more tolerable. 

Between therapy sessions, you may be encouraged to continue practising in your own time to build momentum. 

Who might benefit from ERP?

You might consider exploring ERP therapy if:

• you experience persistent or intrusive thoughts that are hard to shake
• you find yourself repeating actions, rituals, or mental checks to ease anxiety
• anxiety or routines are affecting your daily life or relationships
• you avoid certain places, people, or situations due to fear
• you feel stuck in a cycle of fear and avoidance, even when part of you recognises the fear may not be realistic or logical
• you’ve gained insight through therapy before, but want support changing patterns.

Finding an ERP therapist 

ERP therapy isn’t about facing all your fears at once. It’s about taking steady, practical steps towards the life you want, with the right support by your side. 

Working with a therapist trained in ERP can help you to:

• create a plan that feels achievable 
• move at a pace that feels manageable for you
• stay supported through the more challenging moments.

If you’re considering ERP for OCD, phobias, or other anxiety difficulties, reaching out to a qualified therapist can be a helpful next step.
