OCD EMDR Therapy: How It Works, When It Helps, and What to Expect
For eight months I did ERP with my OCD therapist, sometimes twice a week. I got better at not checking the stove. I stopped washing my hands until they were raw. But every night I still lay in bed replaying the same intrusive image from when I was twelve, and no amount of exposure work seemed to touch it. When I brought it up, my therapist said maybe we needed to look at trauma alongside the OCD. That night I typed "ocd emdr therapy" into my phone, because I had heard the two conditions sometimes overlap and EMDR handles memories differently than ERP does. If you have found yourself doing similar research after ERP has taken you as far as it can, this blog post will walk through the honest evidence, when EMDR actually helps, and what a session looks like.
What EMDR Actually Is (And Why Some OCD Therapists Now Use It)
EMDR stands for Eye Movement Desensitization and Reprocessing. It was developed by psychologist Francine Shapiro in 1987 as a treatment for PTSD, and it has since become one of the most well-established trauma therapies in the world. The therapy uses bilateral stimulation to help the brain reprocess distressing memories, so they lose their emotional charge. Understanding what EMDR is designed to do explains both its potential value for OCD and its real limits. Here is the framing to hold:
A brief history and the Adaptive Information Processing model
EMDR is built on Shapiro's Adaptive Information Processing (AIP) model, which proposes that psychological distress comes from memories that got "stuck" during storage. Bilateral stimulation, delivered through eye movements, tapping, or auditory tones, is thought to help the brain move stuck memories into a more adaptive form. That is why EMDR works so well for PTSD, where the target memory is often obvious.
What makes EMDR fundamentally different from ERP and CBT
ERP asks you to face the situations that trigger obsessions without performing compulsions. CBT works with the thoughts and beliefs that fuel OCD. EMDR does neither. Instead, it targets the underlying memories, images, or worst-case scenarios that keep OCD alive. For some clients, especially those with a trauma history, that difference matters a lot.
Why interest in EMDR for OCD has grown
Clinicians noticed that a subset of OCD patients had unresolved trauma feeding their obsessions, and that ERP alone did not reach those memories. Marilyn Luber's scripted EMDR protocols for anxiety and OCD, along with Krentzel and Tattersall's Distancing Approach for aggressive and sexual OCD, gave therapists structured ways to adapt EMDR for OCD specifically.
The Honest Evidence: Where EMDR for OCD Actually Stands in 2026
This section matters more than most on this topic, because the internet is full of pages that oversell EMDR for OCD in ways that could keep readers from getting the treatment that would actually help most. The honest picture is more nuanced than either "it works" or "it does not work." Here is where the evidence actually stands:
What the International OCD Foundation actually says
The IOCDF, the top authority for OCD treatment, is direct on this question. The International OCD Foundation's official position on EMDR for OCD states that EMDR is not an evidence-based treatment for OCD and is not recommended as a stand-alone treatment. They note EMDR may be useful as part of an overall treatment plan for co-occurring OCD and PTSD, which is exactly where the strongest case for EMDR sits.
What the research studies actually show
A 2021 systematic review published in the Journal of EMDR Practice and Research examined nine studies (six case reports and three group studies) on EMDR for OCD. All studies showed reductions in OCD symptoms measured by the Yale-Brown Obsessive Compulsive Scale (YBOCS). A 2020 randomized controlled trial comparing EMDR and CBT for OCD found comparable results, with no significant difference between the two groups at six-month follow-up. The evidence is promising but preliminary, and most studies had small sample sizes.
Why ERP remains the gold-standard treatment
ERP has decades of research supporting it, dozens of RCTs, and consistent recommendations from every major OCD authority. Response rates typically run 65 to 80 percent for those who complete a course of treatment. If you have not yet tried ERP with a properly trained OCD specialist, getting started with evidence-based OCD treatment is almost always the right first step before exploring alternatives.
How OCD EMDR Therapy Actually Works: The 8-Phase Framework
If EMDR fits your situation, the therapy follows an eight-phase structure regardless of the condition being treated. The phases are the same for PTSD, OCD, or other applications, but what gets targeted changes based on what is driving the distress. Knowing the structure in advance takes a lot of the fear out of starting. Here is what actually happens in each phase:
Phases 1 and 2: history-taking and preparation
The first two phases build the foundation. Your therapist gathers your full history, including OCD symptoms, past trauma, current stressors, and prior treatment. Then they teach you grounding and stabilization skills, so you can regulate your nervous system if reprocessing gets intense. This phase can take one to three sessions, sometimes longer if you have complex trauma alongside OCD.
Phases 3 and 4: target assessment and desensitization
In phase three, you and your therapist choose a specific target for reprocessing. For OCD, this might be a traumatic memory linked to the onset of your symptoms, a feared worst-case scenario, or a particularly distressing intrusive image. Phase four is the actual desensitization, using bilateral stimulation (eye movements, tapping, or tones) while you hold the target in mind. This is the phase most people picture when they think of EMDR.
Phases 5 and 6: installation and body scan
Phase five installs a positive belief to replace the negative one associated with the target. Someone who believed "I am dangerous" because of an intrusive thought might install "I can have thoughts without acting on them." Phase six scans the body for lingering physical distress and processes anything that remains.
Phases 7 and 8: closure and reevaluation
Phase seven closes the session, ensuring you leave calm and stable. Phase eight, at the next session, reevaluates the target to see how much has shifted and what needs further reprocessing. This cycle continues until the target no longer produces distress.
When EMDR Might Actually Help Your OCD
This is the "when it helps" section your title promises, and it is the most practical part of the article. EMDR is not a good fit for every OCD situation, but for certain specific patterns it can genuinely open doors that ERP alone cannot. Recognizing whether you fit one of these patterns matters more than the general question of whether EMDR "works" for OCD. Here are the four scenarios where EMDR most often helps:
When you have OCD alongside PTSD or unresolved trauma
This is the strongest and most agreed-upon indication for EMDR in OCD treatment. If you have both diagnoses, or if a specific traumatic event sits at the emotional root of your obsessions, EMDR can address the trauma directly. Understanding how trauma-informed therapy approaches the connection between OCD and past experiences helps clarify why this pattern responds so well.
When ERP has not worked or feels impossible to start
Some clients cannot engage with ERP because the exposure work feels intolerable or triggers dissociation. Others complete a course of ERP without meaningful gains. In these cases, EMDR may help by lowering the emotional intensity around triggers first, making later ERP more tolerable and effective.
When your OCD started after a specific traumatic event
If you can identify a specific event that preceded your OCD onset (a health scare, an assault, a significant loss, a moment of witnessing harm), EMDR can target that event directly. Trauma-linked OCD often responds better to trauma-focused work than to standard exposure alone.
When the shame or emotional layer is blocking treatment progress
Aggressive OCD, sexual OCD, and religious OCD often carry intense shame that keeps clients from engaging fully with any treatment. Krentzel and Tattersall's Distancing Approach was developed specifically for these subtypes and uses EMDR to address the shame layer before or alongside ERP.
What to Expect: A Realistic Session Timeline for OCD
Beyond the phase structure, most people want to know what treatment actually looks like in real life. How many sessions? What does bilateral stimulation feel like? What comes up? Knowing this in advance makes the process less intimidating and helps you evaluate whether it is working. Here is what typically happens:
What your first two or three sessions look like
The first sessions focus on history, assessment, and preparation. You will not do bilateral stimulation on day one. Your therapist wants to make sure you have the nervous system regulation skills to handle reprocessing before you begin. Expect to talk about your OCD history, your trauma history, and your goals. This phase usually feels like careful conversation, not intense processing.
What bilateral stimulation actually feels like when the target is an obsession
Once you begin reprocessing, you hold the chosen target (a memory, an image, a worst-case scenario) in mind while your therapist guides your eyes side to side, taps rhythmically on your hands, or plays alternating tones through headphones. Most clients describe the experience as unusual but not overwhelming, sometimes surprisingly emotional, and often followed by a sense that the memory feels smaller or further away.
How long treatment typically takes for OCD
Studies show a wide range, from eight to 45 sessions across different protocols. Most OCD-focused EMDR treatment falls in the 12 to 20 session range, though clients with significant trauma may need longer. This is more sessions than a typical PTSD course because OCD targets are often more complex and layered.
How EMDR and ERP Are Often Combined
The most common real-world use of EMDR for OCD is not as a replacement for ERP but as a companion to it. Experienced clinicians blend the two approaches strategically, and knowing how they combine helps you understand what a comprehensive OCD treatment plan might actually look like. Here are the three main ways they get combined:
The sequential approach (EMDR first, then ERP)
Some therapists use EMDR first to address trauma or shame that is blocking ERP engagement. Once the emotional charge has been reduced, ERP becomes more accessible. This approach fits clients who have found ERP intolerable in the past or who freeze during exposure work.
The parallel approach (both running together)
Other therapists alternate between EMDR sessions targeting trauma memories and ERP sessions targeting current obsessions and compulsions. The two treatments work on different layers simultaneously, with EMDR loosening the underlying material and ERP building tolerance for present-day triggers.
When EMDR alone might be sufficient
For a small subset of OCD clients whose symptoms are strongly linked to a discrete trauma and who do not have ongoing compulsive behavior driving the cycle, EMDR alone may produce significant relief. This is the exception, not the rule. Most OCD needs some form of ERP or CBT work alongside any trauma-focused therapy.
How to Find a Therapist Who Actually Knows OCD and EMDR
Finding a therapist trained in EMDR is one thing. Finding one who also understands OCD is another. Many EMDR therapists trained primarily on PTSD do not know how to adapt the protocol for OCD, and using standard PTSD EMDR on OCD can be ineffective or occasionally counterproductive. The right therapist matters more than the modality itself. Here is how to find one:
Credentials to look for
Look for an LICSW, LMFT, LMHC, or clinical psychologist with EMDRIA-certified training plus specific OCD training. The Behavior Therapy Training Institute (BTTI) through the IOCDF is the gold-standard OCD training. Someone with both credentials is rare and worth seeking out. The same care that goes into choosing the right therapist in Boston applies here, with the added specificity of needing dual training.
Questions to ask before booking
Ask what percentage of their caseload is OCD. Ask what specific EMDR training they have for OCD (Luber protocols, Distancing Approach, Flash Forward Technique). Ask whether they also do ERP. Ask how they decide when EMDR is the right choice versus ERP alone. A qualified therapist answers all four with specificity.
When EMDR is not the right choice
EMDR is generally not recommended for people with active suicidal ideation, active substance use disorders, undiagnosed dissociative disorders, or unstable living situations. In these cases, stabilization work comes first. Standard EMDR should also not be used as a stand-alone approach for pure OCD without any trauma component. In that situation, ERP is almost always the better fit.

Frequently Asked Questions
Is EMDR as effective as ERP for OCD?
Not according to current evidence. ERP has decades of research and 65 to 80 percent response rates in clinical trials. EMDR for OCD has nine peer-reviewed studies showing promise, but the sample sizes are small and it is not considered evidence-based as a stand-alone OCD treatment. The 2020 RCT showing comparable results is encouraging but not definitive.
How many EMDR sessions do you need for OCD?
Most OCD-focused EMDR treatment falls in the 12 to 20 session range, though studies have reported effective treatment courses from 8 to 45 sessions. Clients with significant trauma alongside OCD often need longer treatment than clients with more contained targets.
Does EMDR work for OCD without trauma?
The evidence is weakest here. EMDR was developed to reprocess distressing memories, and its strongest results in OCD come when trauma or emotionally charged memories fuel the obsessions. For pure OCD without any trauma component, ERP and other CBT-based approaches remain the recommended treatments.
Can EMDR make OCD worse?
Occasionally, and this is one reason therapist training matters. Improperly applied EMDR can temporarily activate distress without producing resolution, and using standard PTSD protocols on OCD without OCD-specific adaptation can miss the mark. Working with a therapist trained in both OCD and EMDR minimizes this risk.
Should I try EMDR before ERP for my OCD?
Usually not. ERP is the evidence-based first-line treatment and works for most people with OCD. EMDR becomes a legitimate consideration when trauma sits alongside OCD, when ERP has not worked, or when shame or dissociation makes ERP impossible to engage with. Otherwise, ERP first is the right call.
