What Is Obsessive-Compulsive Disorder?

Find a therapist to treat OCD

ERP, ACT, and I-CBT are all evidence-based ways to change your relationship with OCD.

.There isn’t one “right” treatment, there are different ways of approaching OCD.

You have options in OCD treatment and can advocate for yourself.

Be mindful of not getting into a compulsive loop of picking the "perfect" treatment.

If you’ve started exploring therapy for OCD, you’ve likely come across different approaches. There's exposure and response prevention (ERP), acceptance and commitment therapy (ACT), and inference-based cognitive behavioral therapy (I-CBT), a form of CBT specifically targeting OCD.. For many people, choosing can quickly become overwhelming.

It’s also very easy for those with OCD to latch onto the choice process, turning it into another question to focus on: Which one is best? What if I choose the wrong one? What if I waste time?

Rather than approach a decision as something to get “right,” it can be more helpful to think of the treatments as different entry points into the same goal: changing your relationship with OCD so that it no longer dictates how you live your life.

To make the process feel more approachable, I broke down the top three evidence-based treatments for OCD and how to determine the best fit for you.

Exposure and Response Prevention (ERP): Facing Fears

Exposure and response prevention (ERP) is the most widely researched and commonly recommended treatment for OCD, with decades of empirical support. During ERP, you intentionally and systematically approach situations, thoughts, images, or sensations that trigger obsessions, whether through in vivo (real-life) exposures, imaginal scripts, or interoceptive exercises, and you practice response prevention by resistance rituals. such as reassurance-seeking, mental reviewing, checking, or avoidance. Over time, the process retrains your brain to learn that distress can rise and fall on its own and that you can tolerate uncertainty and discomfort without seeking relief through compulsions.

You feel stuck in compulsive behaviors and rituals

You’re constantly seeking certainty, reassurance, or relief

You feel that avoidance is shrinking your life

You’re ready and willing to practice facing your triggers through exposure work

You want to build self-trust in your ability to handle discomfort

You learn best through behavioral practices and consistent daily homework.

ERP helps retrain the OCD brain by allowing intrusive thoughts and doubt to be present without performing compulsions, which ultimately shows your brain that intrusions are not a threat. Rather than trying to calm yourself down or make the anxiety disappear, you allow the discomfort (e.g., anxiety, doubt, guilt, etc.) to rise and fall on its own. Over time, this creates new learning in the brain: I can experience this, and nothing catastrophic happens, and I can tolerate uncomfortable feelings without solving them.

Acceptance & Commitment Therapy (ACT): Psychological Flexibility

Acceptance and commitment therapy (ACT), developed by Steven C. Hayes, offers a different, but highly complementary, perspective. ACT helps you change how you relate to intrusions and emotional discomfort. Through skills like cognitive defusion, mindfulness, and values clarification, you learn to notice thoughts as mental events rather than truths that require engagement. You also learn to tolerate and create distance from anxiety, realizing that you can embrace discomfort while still connecting with what matters to you.

You want a treatment that focuses on values and self-compassion

You have a difficult time accepting the presence of thoughts and emotional discomfort

You would rather focus on exposures that are values-aligned

You’re looking to change your relationship with your internal world

You need more skills than what ERP offers

You learn best through and are open to experiential exercises in sessions.

ACT can be especially helpful if you feel entangled with your thoughts, overwhelmed by emotions, or stuck in cycles of trying to “figure out” what these internal experiences mean. ACT shifts the question from Is this thought true? to Is engaging with this thought helping me live the life I want?

It also supports the development of psychological flexibility, which often makes it easier to engage in ERP and tolerate discomfort. There is growing evidence supporting ACT as both a stand-alone and adjunctive treatment for OCD. Most clinicians, like myself, will pair ERP and ACT.

Inference-Based CBT (I-CBT): Breaking Inferential Confusion

Inference-based CBT (I-CBT), developed by Kieron O'Connor and colleagues, takes a different approach by focusing on the reasoning process underlying OCD: inferential confusion.

From this perspective, the issue is not simply intrusive thoughts but the way the mind moves away from what is directly observable and into imagined possibilities. OCD becomes fueled by “what if” reasoning that feels compelling, even when it is disconnected from reality-based information.

You struggle to trust your sense of self and common sense in the here and now

You do not want to engage in exposure work

You haven’t seen results with other forms of treatment

You want to understand how OCD creates doubt in order to step out of the cycle

You want to build self-trust using your sensory information as opposed to exposure work

You experience taboo themes

You learn best through a cognitive model and homework.

I-CBT helps you identify when you’ve shifted into the OCD sequence and guides you back toward trusting your direct experience, real self/values, and common-sense reasoning. Rather than engaging with the content of the obsession or repeatedly testing it, the goal is to step out of the reasoning process that gave it power in the first place. Over time, you start to realize right away when OCD shows up and the tricks it's trying to play to pull you into the cycle. This gives you more power and knowledge to disengage from OCD and, ultimately, stop reinforcing symptoms.

How to Decide Where to Start?

When people ask how to choose between approaches, the answer is not about mixing every model together or trying to collect as many techniques as possible. Each treatment has its own theory of change, and it is important that your therapist is clear on the model they are using and why.

ERP and ACT are often used together, as ACT can support willingness, defusion, and values-based action, which makes exposure work more effective. I-CBT, however, is a distinct model with a different understanding of how OCD is maintained, and it is used on its own rather than combined with ERP.

While understanding the approaches can be empowering, treatment planning is not something you need to figure out on your own. A trained OCD therapist can help you identify patterns, clarify what is driving your symptoms, and adjust the approach over time. OCD is nuanced, and effective treatment often evolves as new layers of the disorder become more visible.

Being Informed Without Turning It into Another Compulsion

Learning about treatment can be helpful. It can also, at times, become another situation whereby OCD tries to pull you into certainty-seeking. The goal is not to research until you feel 100% sure or to pick a treatment you think is going to get "rid" of OCD. That is compulsive! Many individuals with OCD treatment-hop, trying to seek relief. I always tell clients to really commit to a treatment protocol before trying something new.

You are allowed to ask questions. You are allowed to understand the rationale behind your treatment. You are allowed to share what resonates with you. At the same time, you do not need to pick the “right” treatment in order to begin. You can choose a starting point and adjust as needed.

ERP, ACT, and I-CBT are all defined as evidence-based treatments by The International OCD Foundation. One is not “better” than the other; rather, they’re different ways of helping you relate differently to OCD. The goal is not to find the perfect approach. It is to recognize that you have options and to choose a treatment that resonates with you and how your OCD affects you.

From there, the work becomes about engaging in the process with two feet in staying ope, and showing OCD you’re in the driver’s seat!
