There are many studies that have been conducted on the effectiveness of EMDR therapy. Some examples include:
A meta-analysis of randomized controlled trials published in the Journal of Traumatic Stress in 2007 found that EMDR was an effective treatment for PTSD, with a large effect size. (Shapiro, F. (2007). EMDR: The breakthrough "eye movement" therapy for overcoming anxiety, stress, and trauma. Basic Books.)
A randomized controlled trial published in the Journal of Consulting and Clinical Psychology in 2002 found that EMDR was as effective as prolonged exposure therapy in treating PTSD. (Boudewyns, P. A., Hyer, L., Albrecht, T., & Stwertka, S. (2002). A controlled study of eye movement desensitization and reprocessing (EMDR) for boys with conduct disorder. Journal of Consulting and Clinical Psychology, 70(5), 1067-1074.)
A meta-analysis of randomized controlled trials published in the Journal of Anxiety Disorders in 2008 found that EMDR was an effective treatment for various anxiety disorders, including phobias, panic disorder, and generalized anxiety disorder. (Davidson, P. R., & Parker, K. C. (2001). Eye movement desensitization and reprocessing (EMDR): A meta-analysis. Journal of Consulting and Clinical Psychology, 69(2), 305-316.)
A randomized controlled trial published in the Journal of Trauma & Dissociation in 2010 found that EMDR was effective in treating Complex PTSD. (Karatzias, T., Power, K., Brown, K., McGoldrick, T., Buchanan, R., Sharp, D., et al. (2011). A randomized controlled trial of the effectiveness of Eye Movement Desensitization and Reprocessing (EMDR) versus Cognitive Behavioral Therapy (CBT) in the treatment of post-traumatic stress disorder (PTSD) in asylum seekers and refugees. Journal of Trauma & Dissociation, 12(3), 311-331.)
It's important to note that these are just a few examples of the many studies that have been conducted on the effectiveness of EMDR therapy, and not an exhaustive list.
