META-ANALYSES
EMDR Therapy has been compared to numerous exposure therapy protocols, with and without Cognitive Therapy techniques. It should be noted that exposure therapy uses one to two hours of daily homework and EMDR uses none. The most recent meta-analyses are listed here.

EMDR is equivalent to exposure and other cognitive behavioral treatments and all “are highly efficacious in reducing PTSD symptoms.
Davidson, P.R., & Parker, K.C.H. (2001). Eye movement desensitization and reprocessing (EMDR): A meta-analysis. Journal of Consulting and Clinical Psychology, 69, 305-316. EMDR is equivalent to exposure and other cognitive behavioral treatments. It should be noted that exposure therapy uses one to two hours of daily homework and EMDR uses none.
Lee, C.W., & Cuijpers, P. (2013). A meta-analysis of the contribution of eye movements in processing emotional memories. Journal of Behavior Therapy & Experimental Psychiatry, 44, 231-239. The effect size for the additive effect of eye movements in EMDR treatment studies was moderate and significant (Cohen’s d = 0.41). For the second group of laboratory studies the effect size was large and significant (d = 0.74).
Maxfield, L., & Hyer, L.A. (2002). The relationship between efficacy and methodology in studies investigating EMDR treatment of PTSD. Journal of Clinical Psychology, 58, 23-41 A comprehensive meta-analysis reported the more rigorous the study, the larger the effect.
Rodenburg, R., Benjamin, A., de Roos, C, Meijer, A.M., & Stams, G.J. (2009). Efficacy of EMDR in children: A meta – analysis. Clinical Psychology Review, 29, 599-606. Results indicate efficacy of EMDR when effect sizes are based on comparisons between EMDR and non-established trauma treatment or no-treatment control groups, and incremental efficacy when effect sizes are based on comparisons between EMDR and established (CBT) trauma treatment.

RANDOMIZED CLINICAL TRIALS
Abbasnejad, M., Mahani, K. N., & Zamyad, A. (2007). Efficacy of “eye movement desensitization and reprocessing” in reducing anxiety and unpleasant feelings due to earthquake experience. Psychological Research, 9, 104-117. EMDR is effective in reducing earthquake anxiety and negative emotions (e.g. PTSD, grief, fear, intrusive thoughts, depression, etc) resulting from earthquake experience. Furthermore, results show that, improvement due to EMDR was maintained at a one month follow up.
Ahmad A, Larsson B, & Sundelin-Wahlsten V. (2007). EMDR treatment for children with PTSD: Results of a randomized controlled trial. Nord J Psychiatry, 61, 349-54. Thirty-three 6-16-year-old children with a DSM-IV diagnosis of PTSD were randomly assigned to eight weekly EMDR sessions or the WLC group. EMDR was found to be an effective treatment in children with PTSD from various sources and who were suffering from a variety of co-morbid conditions.
Arabia, E., Manca, M.L. & Solomon, R.M. (2011). EMDR for survivors of life-threatening cardiac events: Results of a pilot study. Journal of EMDR Practice and Research, 5, 2-13. Forty-two patients undergoing cardiac rehabilitation . . . were randomized to a 4-week treatment of EMDR or imaginal exposure (IE). EMDR was effective in reducing PTSD, depressive, and anxiety symptoms and performed significantly better than IE for all variables. Because the standardized IE procedures used were those employed in-session during [prolonged exposure the results are also instructive regarding the relative efficacy of both treatments without the addition of homework.
Capezzani et al. (2013). EMDR and CBT for cancer patients: Comparative study of effects on PTSD, anxiety, and depression. Journal of EMDR Practice and Research, 5, 2-13. This randomized pilot study reported that after eight sessions of treatment, EMDR therapy was superior to a variety of CBT techniques. “Almost all the patients (20 out of 21, 95.2%) did not have PTSD after the EMDR treatment.
Carlson, J., Chemtob, C.M., Rusnak, K., Hedlund, N.L, & Muraoka, M.Y. (1998). Eye movement desensitization and reprocessing (EMDR): Treatment for combat-related post-traumatic stress disorder. Journal of Traumatic Stress, 11, 3-24. Twelve sessions of EMDR eliminated post-traumatic stress disorder in 77.7% of the multiply traumatized combat veterans studied. There was 100% retention in the EMDR condition. Effects were maintained at follow-up. This is the only randomized study to provide a full course of treatment with combat veterans. Other studies (e.g., Boudewyns/Devilly/Jensen/Pitman et al./Macklin et al.) evaluated treatment of only one or two memories, which, according to the International Society for Traumatic Stress Studies Practice Guidelines (2000), is inappropriate for multiple-trauma survivors. The VA/DoD Practice Guideline (2004) also indicates these studies (often with only two sessions) offered insufficient treatment doses for veterans. EMDR therapy is listed as an “A” level treatment in the VA/DoD Practice Guideline (2004, 2010).

Chemtob, C.M., Nakashima, J., & Carlson, J.G. (2002). Brief-treatment for elementary school children with disaster-related PTSD: A field study. Journal of Clinical Psychology, 58, 99-112. EMDR was found to be an effective treatment for children with disaster-related PTSD who had not responded to another intervention. This is the first controlled study for disaster-related PTSD, and the first controlled study examining the treatment of children with PTSD.
Cvetek, R. (2008). EMDR treatment of distressful experiences that fail to meet the criteria for PTSD. Journal of EMDR Practice and Research, 2, 2-14. EMDR treatment of disturbing life events (small “t” trauma) was compared to active listening, and wait list. EMDR produced significantly lower scores on the Impact of Event Scale (mean reduced from “moderate” to “subclinical”) and a significantly smaller increase on the STAI after memory recall.

Prolonged exposure and EMDR for PTSD v. a PTSD waiting-list condition: effects on symptoms of psychosis, depression and social functioning in patients with chronic psychotic disorders. Psychological Medicine, 1-11. In patients with chronic psychotic disorders PE and EMDR not only reduced PTSD symptoms, but also paranoid thoughts. Importantly, in PE and EMDR more patients accomplished the status of their psychotic disorder in remission.
de Roos, C. (2011). A randomised comparison of cognitive behavioural therapy (CBT) and eye movement desensitisation and reprocessing (EMDR) in disaster exposed children. European Journal of Psychotraumatology, 2: 5694 – DOI: 10.3402/ejpt.v2i0.5694. Children (n=52, aged 4-18) were randomly allocated to either CBT (n=26) or EMDR (n=26) in a disaster mental health after-care setting after an explosion of a fireworks factory. Both treatment approaches produced significant reductions on all measures and results were maintained at follow-up. Treatment gains of EMDR were reached in fewer sessions.

Trauma-focused cognitive behavioral therapy or eye movement desensitization and reprocessing: What works in children with posttraumatic stress symptoms? A randomized controlled trial. European Child & Adolescent Psychiatry, 26, 227-236. A mixed sample of full and partial PTSD was evaluated. [B]oth treatments are effective in children with PTSS in an outpatient setting. Results on both child and parent measures support this conclusion.
Edmond, T., Rubin, A., & Wambach, K. (1999). The effectiveness of EMDR with adult female survivors of childhood sexual abuse. Social Work Research, 23, 103-116. EMDR treatment resulted in lower scores (fewer clinical symptoms) on all four of the outcome measures at the three-month follow-up, compared to those in the routine treatment condition. The EMDR group also improved on all standardized measures at 18 months follow up (Edmond & Rubin, 2004, Journal of Child Sexual Abuse).

Research on Social Work Practice, 14, 259-272. Combination of qualitative and quantitative analyses of treatment outcomes with important implications for future rigorous research. Survivors’ narratives indicate that EMDR produces greater trauma resolution, while within eclectic therapy, survivors more highly value their relationship with their therapist, through whom they learn effective coping strategies.
Hogberg, G. et al., (2007). On treatment with eye movement desensitization and reprocessing of chronic post-traumatic stress disorder in public transportation workers: A randomized controlled study. Nordic Journal of Psychiatry, 61, 54-61. Employees who had experienced “person-under-train accident or had been assaulted at work were recruited.” Six sessions of EMDR resulted in remission of PTSD in 67% compared to 11% in the wait list control. Significant effects were documented in Global Assessment of Function (GAF) and Hamilton Depression (HAM-D) score.

Both EMDR and CBT produced significant reduction in PTSD and behavior problems. EMDR was significantly more efficient, using approximately half the number of sessions to achieve results.
Jarero, I., Artigas, L., & Luber, M. (2011). The EMDR protocol for recent critical incidents: Application in a disaster mental health continuum of care context. Journal of EMDR Practice and Research, 5, 82-94. Participants were treated two weeks following a 7.2 earthquake in Mexico. One session of EMDR-PRECI produced significant improvement on symptoms of posttraumatic stress for both the immediate-treatment and waitlist/delayed treatment groups, with results maintained at 12-week follow-up, even though frightening aftershocks continued to occur frequently.

Journal of EMDR Practice and Research, 9, 166–173. Evaluation of co-workers 10 days after they witnessed seven people killed in an explosion revealed a mean of 22 on the SPRINT, indicating severe PTSD symptoms. After two consecutive-day 60-minute EMDR sessions the mean SPRINT scores for immediate and delayed treatment groups declined to equally low levels on both posttest and follow-up.
Kemp M., Drummond P., & McDermott B. (2010). A wait-list controlled pilot study of eye movement desensitization and reprocessing (EMDR) for children with post-traumatic stress disorder (PTSD) symptoms from motor vehicle accidents. Clinical Child Psychology and Psychiatry, 15, 5-25. An effect for EMDR was identified on primary outcome and process measures including the Child Post-Traumatic Stress – Reaction Index, clinician rated diagnostic criteria for PTSD, Subjective Units of Disturbance and Validity of Cognition scales. All participants initially met two or more PTSD criteria. After EMDR treatment, this decreased to 25% in the EMDR group but remained at 100% in the wait-list group.

Treatment of post-traumatic stress disorder: A comparison of stress inoculation training with prolonged exposure and eye movement desensitization and reprocessing. Journal of Clinical Psychology, 58, 1071-1089. Both EMDR and stress inoculation therapy plus prolonged exposure (SITPE) produced significant improvement, with EMDR achieving greater improvement on PTSD intrusive symptoms. Participants in the EMDR condition showed greater gains at three-month follow up. EMDR required three hours of homework compared to 28 hours for SITPE.

British Journal of Psychiatry, 200, 224-231. A comparison of “the efficacy and response pattern of a trauma-focused CBT modality, brief eclectic psychotherapy for PTSD with EMDR. Although both treatments are effective, EMDR results in a faster recovery compared with the more gradual improvement with brief eclectic psychotherapy.
Novo, P. et al. (2014). Eye movement desensitization and reprocessing therapy in subsyndromal bipolar patients with a history of traumatic events: A randomized, controlled pilot-study. Psychiatry Research, 219, 122-128. Although preliminary, our findings support the utility of this treatment approach and suggest that Eye Movement Desensitization and Reprocessing therapy could be a promising and safe therapeutic strategy to reduce trauma symptoms and stabilize mood in traumatized bipolar patients with subsyndromal symptoms.
