EMDR for OCD: What the Research Actually Shows
An honest assessment of EMDR as a treatment for OCD, including what the research shows, when it might complement ERP, and the important role of trauma-OCD comorbidity.
The Short Answer
Exposure and Response Prevention (ERP) is the gold-standard treatment for OCD. That has not changed, and this article is not going to argue otherwise. EMDR was not designed for OCD and should not be used as a standalone treatment for it.
That said, a growing body of research is exploring whether EMDR has a role as a complementary treatment — particularly for people whose OCD co-occurs with trauma, whose symptoms are driven by distressing imagery, or who have not responded fully to ERP alone. About 57% of studies examining EMDR for OCD show positive outcomes, which is encouraging but far from conclusive. Here is what we actually know.
ERP Is the Gold Standard — and It Should Be Your First Choice
Before discussing EMDR, it is important to be direct: if you have OCD, you should be working with a therapist trained in ERP. ERP has decades of research and consistently produces significant improvement in 60% to 80% of people who complete treatment. It is recommended by every major clinical guideline, including those from the American Psychological Association and the National Institute for Health and Care Excellence.
60-80%
ERP works by gradually exposing you to situations that trigger your obsessions while helping you resist performing compulsions. Over time, your brain learns that the feared outcome does not occur and that you can tolerate the uncertainty without ritualizing. This behavioral learning is essential, and EMDR does not provide it.
The Trauma-OCD Connection
Here is where the conversation gets more nuanced. Trauma and OCD co-occur at remarkably high rates.
30-82%
For some people, the relationship between trauma and OCD is direct. A car accident leads to checking compulsions. A sexual assault triggers contamination obsessions. A childhood of emotional abuse fuels perfectionism and intrusive thoughts about being fundamentally bad. In these cases, the OCD and the trauma are entangled — and treating only one may leave the other unresolved.
This is where EMDR becomes relevant. EMDR is one of the most extensively validated treatments for trauma and PTSD. If unresolved trauma is fueling or maintaining your OCD, addressing that trauma with EMDR may improve your overall response to treatment.
What the Research Actually Shows
The evidence for EMDR specifically targeting OCD symptoms is limited but growing.
The positive findings. A systematic review found that approximately 57% of studies examining EMDR for OCD reported positive outcomes, including reductions in obsessive-compulsive symptoms. Some studies have found EMDR to be comparable to ERP in reducing OCD severity, though these studies tend to be small.
The critical caveats. Most studies are small — case series, pilot studies, or trials with limited sample sizes. Many do not adequately control for the trauma component, making it unclear whether EMDR improved OCD specifically or reduced PTSD symptoms that were inflating OCD scores. There are very few large, randomized controlled trials comparing EMDR directly to ERP for OCD.
The intrusive imagery connection. One of the more interesting findings is that EMDR may be particularly relevant for OCD presentations that involve vivid, distressing mental imagery. Some people with OCD experience intrusive thoughts primarily as images — graphic scenes of harm, contamination, or catastrophe. EMDR's mechanism of targeting and reprocessing distressing imagery may have specific utility for this symptom profile.
When EMDR Might Help Alongside ERP
EMDR is most likely to be useful for OCD in these specific scenarios:
Trauma-Driven OCD
When OCD onset is clearly linked to a traumatic event, or when trauma is maintaining the OCD cycle, EMDR can address the trauma while ERP addresses the obsessive-compulsive behaviors. This sequential or parallel approach can be more effective than either treatment alone.
ERP-Resistant Cases
Some people complete a full course of ERP and experience partial but incomplete improvement. If there is an underlying traumatic memory that is driving the remaining symptoms, EMDR may help address what ERP could not reach.
Distressing Intrusive Imagery
If your OCD involves vivid, intrusive images that feel almost like flashbacks — scenes that replay with sensory detail and intense emotional charge — EMDR's reprocessing approach may help reduce the distress associated with that imagery.
Treatment Avoidance Due to Trauma
Some people with both OCD and trauma find ERP too activating because exposure exercises inadvertently trigger trauma responses. In these cases, addressing the trauma with EMDR first can make ERP more tolerable and effective.
When EMDR Is Not the Right Choice for OCD
EMDR does not address the behavioral core of OCD. It does not teach you to resist compulsions, tolerate uncertainty, or break the obsession-compulsion cycle. If your OCD is primarily characterized by doubt, checking, counting, ordering, or mental rituals, EMDR's memory reprocessing mechanism is unlikely to be sufficient.
EMDR should also not be used as a way to avoid the discomfort of ERP. ERP is uncomfortable by design — it works by teaching your brain to sit with distress. Choosing EMDR over ERP because it seems easier would likely mean choosing a less effective treatment.
How to Think About This Practically
If you have OCD, here is a straightforward decision framework:
- Start with ERP. Find a therapist specifically trained in ERP for OCD — the International OCD Foundation (IOCDF) maintains a provider directory. General therapists who "use CBT techniques" are not the same as OCD specialists.
- Assess for trauma. If you have a history of trauma that seems connected to your OCD, discuss this with your therapist. A good OCD therapist will screen for trauma.
- Consider EMDR as an addition, not a replacement. If trauma is complicating your OCD treatment, adding EMDR to address the trauma component may improve outcomes.
- Be skeptical of overselling. Any clinician who claims EMDR can cure OCD or replace ERP is not aligned with the current evidence.
There is no evidence that EMDR can cure OCD. ERP is the most effective treatment for OCD, with decades of research support. EMDR may help reduce OCD symptoms when trauma is a contributing factor, but it does not address the behavioral cycle of obsessions and compulsions that defines the disorder.
Ideally, both. ERP addresses the obsessive-compulsive cycle directly, while EMDR can resolve the underlying trauma that may be fueling the OCD. Many clinicians use a sequential approach — stabilizing OCD symptoms with ERP first, then addressing trauma with EMDR, or vice versa depending on which is more impairing. Discuss the sequencing with a therapist experienced in both.
Some therapists recognize that OCD frequently co-occurs with trauma and that addressing both conditions leads to better outcomes. Others may be less familiar with ERP, which is a specialized skill that not all therapists are trained in. If a therapist recommends EMDR instead of ERP for OCD, ask about their ERP training and experience.
This depends on the complexity of your trauma history. A single traumatic event might be resolved in 3 to 8 EMDR sessions. Complex or repeated trauma may take longer. This addresses the trauma specifically — you would still need ERP for the OCD symptoms themselves.
Yes, some therapists are trained in both. This can be ideal for people with co-occurring OCD and trauma because the therapist can integrate both approaches within a single treatment plan. When searching, look for someone who is specifically trained in ERP for OCD and also certified or trained in EMDR.
The Bottom Line
EMDR is not an OCD treatment. It is a trauma treatment that may have a role in OCD care when trauma and OCD intersect — which they do more often than most people realize. The research is promising but limited. If you have OCD, ERP is where you start. If you also have trauma that seems connected to your OCD, adding EMDR to the picture is a conversation worth having with a qualified clinician.
