Is EMDR evidence-based? What the treatment guidelines say
EMDR has had critics from the start: some called the eye movements a gimmick. At the same time, it is now recommended for PTSD by most major treatment guidelines. This guide summarises what the guidelines actually say, what research shows about the eye movements, and where the evidence is still limited, so you can explain it clearly to clients and colleagues.
The short answer
Yes, for post-traumatic stress disorder. A state-of-the-science review by de Jongh, de Roos and El-Leithy (2024) in the Journal of Traumatic Stress counts more than 30 randomised controlled trials in adults and children, and notes that most international guidelines recommend EMDR as a first-line treatment for PTSD. For other conditions the evidence is more limited.
What the guidelines say
| Guideline | What it says about EMDR |
|---|---|
| WHO (2013) | Trauma-focused CBT or EMDR should be considered for adults, children and adolescents with PTSD. |
| ISTSS (2019) | Strong recommendation for adults, and for children and adolescents, with PTSD. |
| NICE (2018, UK) | Offer EMDR to adults with PTSD who present more than 3 months after a non-combat-related trauma, typically over 8 to 12 sessions. For children and young people aged 7 to 17, consider it only if they don't respond to or engage with trauma-focused CBT. |
| VA/DoD (2023, US) | Recommended, together with cognitive processing therapy and prolonged exposure, as one of the primary psychotherapies for PTSD. |
| APA (2017, US) | Conditional recommendation for adults with PTSD. Strong recommendations went to CBT, cognitive processing therapy, cognitive therapy and prolonged exposure. |
The differences mostly reflect how each panel weighed the evidence and which studies were available at the time, rather than conflicting results. A paper in the Journal of EMDR Practice and Research discusses why the guidelines diverge.
Do the eye movements matter?
This was long the main criticism: perhaps EMDR works only because it is a form of exposure, and the eye movements add nothing. Two lines of research address it.
- Component studies. A meta-analysis by Lee and Cuijpers (2013) found that eye movements had an additional effect, both in clinical trials and in laboratory studies of emotional memories.
- Working memory. Laboratory studies show that holding a memory in mind while making eye movements makes the memory less vivid and less emotional afterwards. The leading explanation is that both tasks compete for limited working memory (van den Hout et al., 2011). That also explains why the stimulation needs to be demanding enough, but not so demanding that the client loses the memory.
Auditory and tactile stimulation are widely used too, but there is less research showing they are as effective as eye movements. Our guide to visual vs auditory bilateral stimulation goes into the details.
Beyond PTSD
EMDR is also being studied for anxiety disorders, depression, psychosis, chronic pain and other conditions, often as an addition to standard care. Results in several areas are promising, but the trials are fewer and smaller than for PTSD, and the major guidelines don't recommend EMDR as a first-line treatment for these conditions. Be open about this with clients who come for something other than trauma.
What about online EMDR?
The evidence on remote EMDR is younger. A systematic review in Frontiers in Psychiatry of 16 studies found promising effects on PTSD symptoms, anxiety and depression, but most studies were small and few had a control group. For now, the safest approach is to deliver the full protocol online exactly as you would in person, with extra attention to safety. Our guide to doing EMDR online explains how.
Explaining the evidence to clients
- EMDR is one of the best-researched treatments for trauma, and the World Health Organization includes it in its guidelines for PTSD.
- It is a structured therapy, not just eye movements. Preparation and safety are part of it.
- How many sessions are needed depends on the number and type of traumatic experiences.
- Other trauma-focused therapies work too. If EMDR doesn't suit someone, there are good alternatives.
