Evidence summary

Independent evidence and credibility scorecard

Independence tiers: 1 = regulator or government body; 2 = academic or Cochrane team with no declared commercial funding for the work; 3 = independent authors analysing mostly manufacturer-run trials, or minor declared industry ties; 4 = manufacturer-funded or manufacturer-authored. For a therapy, we treat EMDR training bodies and practitioner associations as the "manufacturer", and authors who earn income from EMDR training as having a declared tie. Credibility runs from A (highest) to D.

Ten of the 12 sources are based wholly or partly in the UK, the US or the Netherlands. Many of the reviews and trials we relied on come from British and Dutch teams, so findings may partly reflect how the therapy is delivered in those health systems.

What EMDR is: history and the eight phases

EMDR is a talking therapy for trauma. The person recalls a distressing memory in short bursts while paying attention to something that alternates left and right. Originally this was the therapist's moving finger; today it can also be a light bar, tones in headphones, or taps on the hands (VA; Cleveland Clinic). WHO notes that, unlike trauma-focused CBT, EMDR does not involve detailed descriptions of the event, direct challenging of beliefs, extended exposure or homework (WHO 2013).

History: 1987 to today

According to the EMDR Institute, Francine Shapiro noticed in 1987, while walking in a park, that moving her eyes seemed to ease her own distressing thoughts. She called the first version "eye movement desensitization" (EMD), began training clinicians in 1990, created the EMDR Institute that year, and renamed the method EMDR in 1991 (EMDR Institute history). Her 1989 journal paper described a single-session procedure with a case history and a "previous controlled study" (Shapiro 1989). The Institute says training was at first limited to licensed clinicians trained by the Institute itself, and that these restrictions were lifted in 1995 (EMDR Institute).

The eight phases

Guidelines describe EMDR as a standardised, eight-phase therapy (ISTSS 2019). A US hospital summary lists them as follows (Cleveland Clinic):

1. History taking — assessing whether EMDR suits the person, and choosing target memories and goals.
2. Preparation — explaining the process and teaching ways to calm down and feel safe.
3. Assessment — picking a target image, the negative belief about the self linked to it, a preferred positive belief, emotions and body sensations.
4. Desensitisation — sets of bilateral stimulation while holding the memory in mind, noticing what comes up.
5. Installation — strengthening the positive belief.
6. Body scan — checking for remaining physical tension linked to the memory.
7. Closure — making sure the person leaves the session settled.
8. Re-evaluation — reviewing progress at the next session and planning further targets.

Phases 1 and 2 usually happen early; phases 3 to 8 repeat across later sessions (Cleveland Clinic).

Status by country

EMDR is not a regulated product, so there is no licensing body for the therapy itself. Its standing comes from clinical guidelines. In England, NICE recommends it for some adults with PTSD after non-combat trauma (NICE), and it is listed among NHS Talking Therapies options (NHS). In the US, the VA and Department of Defense recommend it (VA/DoD 2023). WHO's 2023 mhGAP guideline lists EMDR among the psychological interventions that "should be considered" for adults with PTSD (conditional recommendation; low certainty of evidence) and that "should be offered" to children and adolescents with PTSD (moderate-certainty evidence) (WHO 2023; recommendation records: adults, children). This replaced the 2013 wording (WHO 2013). The name itself is a US registered service mark (USPTO).

How it works: the eye-movement debate

Shapiro's own explanation, called the adaptive information processing model, holds that distress comes from "unprocessed memories" (WHO 2013 glossary), and that bilateral stimulation helps the person's own information processing integrate the memory (ISTSS description). That model has not been directly tested in a way that would prove it. What can be tested is whether the eye movements add anything.

Dismantling studies: do the eye movements matter?

A dismantling study compares the full therapy with the same therapy minus one component. A 2001 meta-analysis of 34 studies found EMDR no better than other exposure techniques, and no added effect of eye movements. Its authors concluded that the eye movements "are unnecessary" (Davidson & Parker 2001).

A 2013 meta-analysis argued the earlier one may have missed a real effect. Across 15 clinical studies it found a moderate added effect of eye movements (d = 0.41), and across 11 laboratory studies a large one (d = 0.74) (Lee & Cuijpers 2013). In plain terms, d = 0.41 means the average person with eye movements did better than about two-thirds of people without them.

A 2016 dismantling trial randomised 139 patients with PTSD to EMDR with eye movements, EMDR while staring at the therapist's still hand, or EMDR with no visual focus. Both visual-focus groups improved more than the no-focus group, but eye movements were no better than a fixed gaze (Sack et al. 2016). That suggests "dual attention" may help, but not side-to-side eye movement as such.

Working-memory theory

The leading scientific explanation comes from memory research. Holding a memory in mind and doing a second demanding task at the same time competes for limited working memory, so the image becomes less vivid and less emotional. Early experiments found the same blurring with eye movements and with a tapping task that involved no eye movements (Andrade, Kavanagh & Baddeley 1997). A 2021 meta-analysis of 53 laboratory studies found dual tasks cut vividness of negative memories by about 9 points and emotionality by about 6 points on 100-point scales (Mertens, Lund & Engelhard 2021). These are modest changes in laboratory volunteers. They do not show that the effect drives recovery from PTSD in clinic.

What is proven in humans: EMDR as a whole package reduces PTSD symptoms. What is not proven: that the eye movements are essential, or that the adaptive information processing model is correct. Clinics already use taps or tones instead of eye movements.

What works and what does not

Benefits by claim

PTSD in adults

This is where the evidence is strongest. A 2020 systematic review and meta-analysis called trauma-focused CBT and EMDR the first-line treatments (Lewis et al. 2020). A network meta-analysis of 90 trials and 6,560 people, put EMDR among the most effective options against waitlist (SMD −2.07, 95% credible interval −2.70 to −1.44), with effects that lasted 1 to 4 months after treatment (Mavranezouli et al. 2020).

The quality caveat is real. The 2013 Cochrane review rated every comparison as very low quality, because trials were small, often underpowered and at high or unclear risk of bias (Bisson et al. 2013). A 76-trial review found that EMDR's apparent edge over other therapies vanished when only low-risk-of-bias trials were counted (Cuijpers et al. 2020).

What guidelines say. NICE recommends EMDR for some adults with PTSD after non-combat trauma, with the timing and preference conditions set out in NG116 (NICE NG116); recommendations 1.6.18 and 1.6.19 were checked in this pass. NICE did not extend its recommendation to combat-related trauma. WHO's 2013 guideline said EMDR, trauma-focused CBT or stress management "should be considered", with moderate-quality evidence for EMDR in adults (WHO 2013). Its 2023 update keeps EMDR on the list for adults as a conditional recommendation (low certainty of evidence), and cautions that lay providers delivering EMDR may carry risks (WHO mhGAP 2023 recommendation record). ISTSS also recommends EMDR alongside cognitive processing therapy, cognitive therapy and prolonged exposure (ISTSS 2019). The VA/DoD recommends cognitive processing therapy, EMDR or prolonged exposure, and prefers these over medication (VA/DoD 2023).

EMDR vs trauma-focused CBT and prolonged exposure

On average there is no clear winner. Lewis 2020 rated trauma-focused CBT and EMDR as the two first-line treatments, with cognitive processing therapy, cognitive therapy and prolonged exposure as the strongest-evidence trauma-focused CBT options (Lewis 2020). Pooling raw data from 8 trials (346 patients) also found no difference in symptoms, remission or dropout (Wright et al. 2024).

Individual trials point in different directions. In a trial of 60 people, prolonged exposure reduced avoidance and re-experiencing more than EMDR, which did no better than relaxation (Taylor et al. 2003). In a trial of 140 outpatients, EMDR and brief eclectic psychotherapy ended up equally effective, but EMDR worked faster (Nijdam et al. 2012). In 155 adults with PTSD from childhood abuse, EMDR and imagery rescripting both produced large improvements (d = 1.73 and 1.72) with only 7.7% dropout (Boterhoven de Haan et al. 2020). A practical difference is homework: trauma-focused CBT usually includes it and EMDR does not (WHO). The EMDR-funded 2025 review is cited only for its funding; its findings were not checked in this pass (Simpson et al. 2025, funded by the EMDR Association UK).

PTSD in children and teenagers

The evidence is smaller. A 2020 network meta-analysis of 32 trials in young people (Mavranezouli et al. 2020) placed EMDR behind several trauma-focused CBT options; the order of effect sizes was checked against the abstract. WHO rated the evidence for EMDR in children as low quality in 2013 (WHO 2013); its 2023 update says psychological interventions, including trauma-focused CBT and EMDR, "should be offered" to children and adolescents with PTSD, as a strong recommendation, with a caution that lay providers may carry risks (WHO mhGAP 2023 recommendation record), while ISTSS also recommends it (ISTSS). A new Cochrane review on children is under way; only its protocol has been published (Illum et al. 2025).

Soon after a trauma

WHO made no recommendation for EMDR in the first month after trauma, for adults or children, because evidence was very low quality (WHO 2013). ISTSS lists single-session EMDR in the first three months as having only "emerging evidence", but gives multi-session EMDR in that window a standard recommendation for adults with PTSD symptoms (ISTSS 2019).

Complex PTSD and childhood trauma

Our separate complex PTSD guide covers the condition in full. For EMDR specifically, the strongest direct trial is the childhood-abuse study above, where EMDR also reduced depression and dissociation (Boterhoven de Haan 2020). Its author list has not been checked for training ties (Psychology Training), and it compared two active therapies without a waitlist group.

PTSD alongside psychosis

People with psychosis are usually excluded from PTSD trials. A trial randomised 155 people with a psychotic disorder and chronic PTSD to 8 sessions of EMDR, prolonged exposure or waitlist. EMDR beat waitlist (between-group effect size d = 0.65, P = 0.001; prolonged exposure d = 0.78) (van den Berg et al. 2015). We could not re-check the adverse-event comparison with the waitlist (van den Berg et al. 2016). EMDR did not treat the psychosis itself.

Depression, anxiety, pain and other uses

EMDR is promoted for many conditions beyond trauma. The only broad independent review found small numbers of high-risk-of-bias trials in phobias and test anxiety, and too few trials to pool results for any other problem. Its conclusion: "not enough evidence" to advise EMDR outside PTSD (Cuijpers et al. 2020). We found no national guideline that recommends EMDR as a treatment for depression, chronic pain or addiction.

Intensive formats

Some clinics deliver EMDR daily over one or two weeks. A programme combining prolonged exposure and EMDR (16 sessions over 8 days, plus exercise) reported large symptom drops (d = 1.64), loss of diagnosis in 54.9% and 2.3% dropout in 347 people with severe PTSD (Van Woudenberg et al. 2018). There was no control group, . Intensive EMDR is promising but not proven better than weekly sessions.

Risks and adverse effects

• Temporary distress. Recalling trauma brings discomfort. The VA says these feelings "are usually brief" (VA). Cleveland Clinic lists negative thoughts or feelings between sessions as the most common effect (Cleveland Clinic).
• Symptom worsening. In a 60-person trial, worsening was no more common with EMDR than with prolonged exposure or relaxation (Taylor 2003). In the psychosis trial, there was no rise in hallucinations, dissociation or suicidality in the first sessions (van den Berg 2016).
• Dropout. Cochrane found some evidence of more dropout in active trauma therapies than on waitlists (Bisson 2013). In pooled patient data, men were more likely than women to drop out of EMDR (Wright 2024).
• Dissociation. EMDR developers created special protocols for dissociative disorders in the early 1990s (EMDR Institute). We found no good trial data on how often EMDR triggers severe dissociation. See our dissociative disorders guide.
• Harm reporting is thin. Most trials do not report adverse events systematically. "No harms found" often means harms were not measured.

Combining it with medicines and other therapies

EMDR has no drug interactions. The questions are about sequencing and combining.

• Antidepressants. WHO says SSRIs and tricyclics should not be first-line for adult PTSD, and should be considered if stress management, trauma-focused CBT or EMDR have failed or are unavailable, or if there is moderate–severe depression (WHO 2013). The VA/DoD recommends these psychotherapies over medication (VA/DoD 2023). Do not stop a prescribed medicine to start EMDR without medical advice (NHS).
• Other trauma therapies. Intensive programmes combine EMDR with prolonged exposure (Van Woudenberg 2018). We found no trial showing that combining them beats either alone.
• Stabilisation first? The psychosis trial delivered EMDR without a preceding stabilisation phase and found it safe (van den Berg 2015). How much preparation is needed for complex cases is still debated.

Who it may not suit

• People in an active legal case as a witness or complainant, until they have discussed the memory concerns above with their lawyer or the police.
• Children under 7: NICE's EMDR recommendation covers ages 7 to 17, and then only after trauma-focused CBT (NICE).
• Combat-related PTSD: NICE's recommendation is limited to non-combat trauma (NICE), although the VA/DoD recommends EMDR for PTSD generally (VA/DoD).
• People at immediate risk of suicide or in an acute crisis, who need crisis care first. See our crisis warning signs guide.
• Visual impairment or eye discomfort: Taps or tones can be used instead.
• Pregnancy: we found no evidence-based reason to avoid EMDR, and no trials specifically in pregnancy.

How it is delivered, finding a therapist and cost

Course length. EMDR should follow a validated manual and be delivered by trained practitioners with ongoing supervision. The VA describes about 3 months of weekly 50- to 90-minute sessions (VA).

Training standards. EMDRIA-approved basic training includes 20 hours of teaching, 20 hours of supervised practice and 10 hours of consultation (EMDRIA). "EMDR-trained" means a therapist completed basic training; "EMDRIA Certified" and EMDR Europe "accredited" mean further supervised experience.

Finding an accredited therapist. In the UK, the EMDR Association UK lists therapists who have done EMDR Europe-authorised training and are accredited (EMDR UK directory). In the US, EMDRIA keeps a directory of members (EMDRIA). Elsewhere in Europe, EMDR Europe links national associations (EMDR Europe). These directories are run by membership bodies, so they confirm training, not results. Also check the therapist's core professional registration, for example as a clinical psychologist or psychotherapist.

Cost. On the NHS in England, EMDR is free through PTSD services and NHS Talking Therapies (NHS), though waiting times vary. US veterans can get it through the VA (VA). We found no independent survey of private session fees; total cost is roughly the private hourly rate times 8 to 12 sessions.

Follow the money: who sells it and who funded the evidence

Who sells EMDR

• EMDR Institute, Inc. (California, US). Founded by Shapiro in 1990 (incorporation date not checked) (EMDR Institute). It owns the US service mark "EMDR" for "educational seminars for professionals in the field of mental health", registered in 1993 (maintained per a trademark aggregator record; USPTO status not checked directly) (USPTO). It charges licensed clinicians $750 per training weekend, with two weekends needed; consultation fees are extra (EMDR Institute fees).
• EMDRIA (EMDR International Association). A 501(c)(6) business league, not a charity. In 2023 it reported revenue of $5,237,855 (ProPublica, IRS Form 990). It approves basic training and certifies therapists (EMDRIA).
• EMDR Europe is an association of national member associations (membership figures not checked), and accredits trainers (EMDR Europe). The EMDR Association UK offers accreditation and a directory to members (EMDR UK).
• Independent trainers. Private companies also run accredited trainings, for example an Australian firm that lists a trainer named Chris Lee, a co-author of the 2013 eye-movement meta-analysis (Psychology Training).

None of this is unusual for a branded psychotherapy. CBT, schema therapy and others also have paid trainings and accrediting bodies. It matters because people who earn from training have a reason to publish positive results.

Who funded the trials and reviews

• Public or unfunded: the Lewis 2020 review (funding statement not re-checked) (Lewis 2020); the network meta-analyses (funding statements not re-checked) (Mavranezouli 2020); the WHO guideline (UNHCR and WHO Jordan) (WHO).
• EMDR-body funded: the EMDR Association UK announced that it funded this University of Sheffield review (Simpson et al. 2025).
• Not accessed: funding statements for the Cuijpers 2020 review, the Wright 2024 patient-data analysis, the van den Berg psychosis trial and several older trials (see gaps below).

Researcher allegiance

Many key EMDR studies include authors who train clinicians or run EMDR services. Declared examples: the intensive-programme paper states one author "receives income from published books on EMDR therapy and for the training of postdoctoral professionals" (Van Woudenberg 2018). The 2013 eye-movement meta-analysis's first author is listed as a trainer at an EMDR training company (Psychology Training). The independent check is that EMDR's advantage over other therapies disappears in low-risk-of-bias trials, while its advantage over no treatment remains (Cuijpers 2020).

Documented historical criticism

• Herbert et al. (2000), a team of seven authors, argued that EMDR's popularity had "outstripped" the evidence and raised concerns about its "aggressive commercial promotion" and marketing practices (Clinical Psychology Review).
• McNally (1999), compared EMDR's rapid spread with that of 18th-century Mesmerism (Journal of Anxiety Disorders).
• The EMDR Institute's response: its history page acknowledges Shapiro was "severely criticized" for her dissemination method and says early training restrictions were meant as safeguards while the method was experimental (EMDR Institute).

Since those critiques, larger and better trials have confirmed EMDR works for PTSD. The eye-movement question they raised remains open. We found no regulatory actions, lawsuits or official sanctions against the EMDR Institute or EMDRIA.

What this means: The core finding, that EMDR helps adults with PTSD about as much as trauma-focused CBT, is supported by government guidelines and unfunded or publicly funded reviews with no stake in EMDR. The more ambitious claims, that eye movements are essential, that EMDR beats other therapies, or that it treats many other conditions, rely more on researchers with training or practice ties and do not survive the strictest independent analyses.
