Evidence-Based Treatments for OCD: CBT, ERP and Other Therapy Options

Understanding what works — and what really makes the difference.

Feeling stuck with OCD? You’re not alone.

If you’re living with obsessive-compulsive disorder (OCD), you’ve probably tried hard to stop your thoughts or control your anxiety — and found that it only makes things worse. You might be wondering what the best evidence-based treatments for OCD actually are, and whether they could help you.

That’s a fair question. There’s a lot of advice online, and some of it is confusing or contradictory. You might hear about medication, CBT, or exposure therapy, and not know which one is right for you.

This article is here to give you a clear, evidence-based overview — without the jargon — so you can make an informed decision about your next step.

At Openforwards, we help people with OCD and anxiety using therapies that are scientifically backed, practical, and compassionate. We’ll walk you through the key treatments recommended by the NICE Guidelines, explain how they work, and show how we integrate modern approaches like ACT (Acceptance and Commitment Therapy) to make treatment more effective and meaningful.

The Best Evidence-Based Treatments for OCD

Quick Summary: Best Evidence-Based Treatments for OCD

Treatment	What it involves	Recommended By	Best For	Evidence Rating
CBT with Exposure & Response Prevention (ERP)	Facing fears gradually and resisting compulsions	NICE, NHS	Core OCD symptoms	⭐⭐⭐⭐⭐
ACT-Enhanced Exposure	Adds mindfulness, values, and willingness training to ERP	Emerging evidence	People who avoid exposure or seek a values-based approach	⭐⭐⭐⭐
SSRIs (Prescribed Drugs)	Reduces intrusive thoughts and anxiety	NICE, NHS	Moderate-to-severe OCD or combined treatment	⭐⭐⭐⭐
Combination (Therapy & Medication)	Using ERP/ACT alongside SSRIs	NICE, clinical trials	Severe or long-term OCD	⭐⭐⭐⭐⭐

1. Cognitive Behavioural Therapy (CBT), including a specific method called Exposure and Response Prevention (ERP)
2. Medication, usually a type of antidepressant called an SSRI

According to the National Institute for Health and Care Excellence (NICE), the best evidence-based treatments for OCD are:

That’s the official guidance used across the NHS and Talking Therapies services.

But recovery isn’t just about following a formula — it’s about how these treatments are delivered, the skill of your therapist, and how well you can engage with the process.

At Openforwards, our therapists are trained to combine evidence-based methods with compassion and creativity, helping you face OCD at a pace that feels safe yet effective.

Exposure and Response Prevention (ERP): Facing fears, not feeding them

ERP is considered the gold standard psychological treatment for OCD. Here’s what it involves, in plain English:

• Exposure means gradually and directly facing the thoughts, images, memories, sensations, emotions or situations that trigger your anxiety.
• Response Prevention means resisting the urge to carry out compulsions or rituals (like washing, checking, or seeking reassurance).

At first, this can sound terrifying. Why would you choose to feel anxious? But here’s the paradox: the more you avoid or neutralise anxiety, the stronger it becomes. ERP helps your brain learn a new lesson — that you can feel anxiety without acting on it, and that it naturally fades over time.

The goal isn’t to get rid of anxiety altogether, but to break the cycle of fear and compulsion so that OCD stops controlling your life.

Frequently Asked Questions About OCD Treatment

A real story (shared with permission)

A few years ago, I worked with someone — let’s call her Sarah — who spent hours each day checking doors, taps, and appliances. She knew it didn’t make sense, but she couldn’t stop. Together, we created small, structured challenges: leaving the house without checking more than once, sitting with the anxiety, and noticing that nothing bad happened.

In the early weeks, she felt awful — shaky, tearful, certain something bad was going to happen. But gradually, as she practised, her anxiety stopped running the show. She started spending less time on rituals and more time doing what she loved.

That’s what ERP is really about — learning freedom through courage, one small step at a time.

Why ACT Adds Something Extra

At Openforwards, we often use an enhanced form of exposure based on Acceptance and Commitment Therapy (ACT). This approach doesn’t just aim to reduce anxiety — it helps you live a meaningful life while anxiety is present.

Where traditional ERP focuses on getting used to fear, ACT-enhanced exposure focuses on learning to make room for it.

We do this by helping you build three key skills:

1. Willingness: opening up to uncomfortable thoughts and sensations rather than fighting them.
2. Defusion: seeing intrusive thoughts as just thoughts — not rules you need to follow.
3. Values: using what matters most to you (e.g. family, love, creativity, honesty) as your reason for doing exposure practice.

So instead of “I have to touch this doorknob to prove I can do it,” you might say, “I’m touching this doorknob because I want to be present for my family without OCD running my life.”

That shift turns exposure into an act of purpose and self-respect, not punishment.

Why Anxiety Reduction Isn’t the Goal

Research shows that how much your anxiety drops during a session doesn’t predict long-term recovery. People who get better aren’t necessarily the ones who feel calmer fastest — they’re the ones who keep practising, even when it’s hard.

So in therapy, we focus less on “getting rid of anxiety” and more on “building the capacity to live fully with it.” Paradoxically, that’s often when the anxiety finally loosens its grip.

The Therapist Factor: Skill and Courage Matter

You might assume that if ERP is the best treatment, all therapists use it. Unfortunately, that’s not the case. Studies show that many therapists avoid exposure because they worry it could distress their clients or make things worse.

That fear — sometimes called anxiety sensitivity — can lead to watered-down treatment. The result? People stay stuck.

At Openforwards, our therapists are specially trained in ERP and ACT. We know how to guide exposure carefully, with compassion and courage. We help clients go at the right pace, stay accountable, and reconnect with what matters most.

It takes bravery on both sides. The best outcomes happen when therapist and client work together — both willing to face discomfort in the service of freedom.

What About Medication?

Prescribed drugs can help reduce the intensity of anxiety and intrusive thoughts, especially when the effects are severe. In such instances, NICE recommends SSRIs as a first-line option alongside therapy. For some people, combining prescribed drugs with CBT/ERP gives the best results.

If you’re considering medication, your GP or psychiatrist can help you weigh up the benefits and side effects. Therapy can often begin alongside or after medication.  However, medication may inhibit your progress due to emotional numbing and reducing your dosage or coming off it completely can support your recovery.

Making a Decision About Treatment

Here’s what the research — and experience — tell us:

• The best evidence-based treatments for OCD are ERP/CBT, ACT-enhanced exposure, and in some cases, SSRIs (sometimes in combination).
• Anxiety reduction isn’t the key — learning, willingness, and courage are.
• Therapist skill matters — training, supervision, and compassion make exposure both safe and effective.
• Change happens through practice, not just insight.

When you’re looking for therapy, choose someone who:
✅ Offers ERP as part of CBT
✅ Has experience treating OCD and anxiety disorders
✅ Integrates values and meaning into the work
✅ Supports regular practice between sessions

How to Decide Which OCD Treatment Is Right for You

• Mild OCD: Start with CBT/ERP in NHS Talking Therapies or private practice.
• Moderate to Severe OCD: Combine ERP/CBT with medication (SSRIs).
• If you’ve tried therapy before: Ask about ACT-enhanced or inhibitory learning-based exposure.
• If anxiety feels unbearable: Begin with willingness and mindfulness skills, then gradually introduce exposure.
• Always choose: A therapist trained in ERP and ACT who offers structured, supervised practice.

What to Do Next

If you’re struggling with OCD, you don’t have to face it alone. At Openforwards, we specialise in helping people face fear wisely, using evidence-based therapies that restore hope and choice.

Whatever you decide, remember: recovery isn’t about becoming fearless — it’s about learning to live well with fear.
