Study Comparison
| Study | Year | Type | Journal | Key Finding |
|---|---|---|---|---|
| Wright SL et al. | 2024 | Psychological Medicine | Individual participant data meta-analysis found no significant difference between EMDR and other psychological treatments for PTSD symptom severity, response, remission, or dropout rates. | |
| Seok J et al. | 2024 | Journal of Clinical Medicine | Meta-analysis of 25 RCTs (n=1,042) found EMDR significantly reduces depression (Hedges' g = 0.75), with greater effects in severe cases. | |
| Rasines-Laudes P et al. | 2023 | Psicothema | Meta-analysis of 18 RCTs (n=1,213) found small effect sizes for EMDR in reducing PTSD symptoms, anxiety, and depression at post-treatment and maintenance. | |
| Cuijpers P et al. | 2021 | Cognitive behaviour therapy | Large meta-analysis of 76 trials found EMDR effective for mental health problems (g = 0.93 vs controls), though superiority over other therapies disappeared in low risk-of-bias studies | |

| Lee CW et al. | 2013 | Study | Journal of Behavior Therapy and Experimental Psychiatry | Meta-analysis confirmed eye movements during memory recall reduce emotional intensity, supporting the working memory theory of EMDR's mechanism. |
Study Details
Psychological Medicine
View Summary
This systematic review and individual participant data (IPD) meta-analysis compared EMDR directly against other established psychological therapies for PTSD. IPD meta-analysis is considered a gold-standard approach because it uses raw data from individual participants rather than aggregate study-level statistics, enabling more precise and nuanced comparisons.
The analysis found no statistically significant differences between EMDR and other psychological treatments (primarily trauma-focused CBT) on any outcome measure, including PTSD symptom severity, treatment response rates, remission rates, and dropout rates. This suggests that EMDR and other evidence-based psychological therapies for PTSD produce broadly equivalent outcomes.
These findings are important for clinical practice, as they suggest that the choice between EMDR and other trauma-focused therapies can be guided by patient preference, therapist expertise, and practical considerations rather than differential efficacy.
Journal of Clinical Medicine
View Summary
This meta-analysis and meta-regression examined the efficacy of EMDR specifically for depression by pooling data from 25 randomized controlled trials with 1,042 participants. While EMDR is primarily known as a PTSD treatment, depression is a frequent comorbidity and an increasingly studied standalone target for EMDR.
The overall analysis found a moderate-to-large effect size (Hedges' g = 0.75) favoring EMDR over control conditions for depression reduction. Meta-regression analyses revealed that baseline depression severity was a significant moderator: participants with more severe depression at baseline showed larger treatment effects. This suggests EMDR may be particularly beneficial for individuals with significant depressive symptoms.
Subgroup analyses explored the influence of control condition type, number of sessions, and whether depression was the primary diagnosis versus a comorbidity. The findings expand the evidence base for EMDR beyond PTSD, supporting its potential utility as a treatment for depressive disorders.
Psicothema
View Summary
This systematic review and meta-analysis evaluated the efficacy of Eye Movement Desensitization and Reprocessing (EMDR) for post-traumatic stress disorder by analyzing 18 randomized clinical trials with 1,213 participants.
The analysis found small but statistically significant effect sizes for EMDR in reducing PTSD symptom severity compared to control conditions at both post-treatment and follow-up timepoints. EMDR also showed small effects on comorbid anxiety and depression symptoms. While the results support EMDR as an effective treatment for PTSD, the effect sizes were modest, suggesting the magnitude of benefit may be more limited than some earlier reviews indicated.
The findings reinforce EMDR's standing as an evidence-based treatment for PTSD while providing a more nuanced picture of its efficacy across different outcome measures and timepoints.
Cognitive behaviour therapy
View Summary
This comprehensive systematic review and meta-analysis included 76 trials examining EMDR for various mental health problems. Most trials (62%) focused on PTSD. EMDR showed large effects compared to control conditions (g = 0.93) and small-to-moderate effects compared to other therapies (g = 0.36). However, the superiority over other therapies was not maintained in studies with low risk of bias.
Journal of psychiatric research
View Summary
This was the first meta-analysis to specifically evaluate EMDR's effectiveness for anxiety disorders (as opposed to PTSD). Seventeen trials with 647 participants were included. Results indicated EMDR is efficacious for reducing symptoms of anxiety, panic, phobia, and behavioral/somatic symptoms.
Cochrane Database of Systematic Reviews
View Summary
This Cochrane systematic review examined psychological treatments for PTSD in adults. The review included 70 randomized controlled trials comparing various psychological therapies.
Both EMDR and trauma-focused cognitive behavioral therapy (TF-CBT) showed strong evidence of efficacy for PTSD treatment. EMDR was comparable to TF-CBT in outcomes, supporting its status as a first-line treatment for PTSD.
PLOS One
View Summary
This comprehensive meta-analysis evaluated the efficacy of Eye Movement Desensitization and Reprocessing (EMDR) therapy for PTSD across 26 randomized controlled trials involving over 1,800 participants.
Results showed EMDR significantly reduced PTSD symptoms compared to waitlist controls and was comparable to other trauma-focused therapies like CBT. Effects were maintained at follow-up assessments, suggesting durable benefits.
The analysis supports EMDR as an effective first-line treatment for PTSD, with the advantage of requiring fewer sessions than some alternative approaches.
Journal of Behavior Therapy and Experimental Psychiatry
View Summary
This meta-analysis examined laboratory studies testing whether eye movements - the core component of EMDR therapy - actually reduce the emotional intensity of negative memories.
The working memory theory proposes that simultaneously holding a memory in mind while making eye movements taxes working memory, which degrades the vividness and emotionality of the memory.
Results from 26 studies confirmed that eye movements significantly reduce both vividness and emotional intensity of negative memories compared to control conditions, providing mechanistic support for EMDR's effectiveness.
Evidence Assessment
