Comparative efficacy, speed, and adverse effects of three PTSD treatments: exposure therapy, EMDR, and relaxation training.

The authors examined the efficacy, speed, and incidence of symptom worsening for 3 treatments of posttraumatic stress disorder (PTSD): prolonged exposure, relaxation training, or eye movement desensitization and reprocessing (EMDR; N = 60). Treaments did not differ in attrition, in the incidence of symptom worsening, or in their effects on numbing and hyperarousal symptoms. Compared with EMDR and relaxation training, exposure therapy (a) produced significantly larger reductions in avoidance and reexperiencing symptoms, (b) tended to be faster at reducing avoidance, and (c) tended to yield a greater proportion of participants who no longer met criteria for PTSD after treatment.

Eye Movement Desensitization and Reprocessing (EMDR): information processing in the treatment of trauma.

Eye Movement Desensitization and Reprocessing (EMDR) is an efficacious and efficient treatment for posttraumatic stress disorder (PTSD). This article provides a brief overview of the findings of 20 controlled-outcome studies and describes Shapiro's Adaptive Information Processing model. This model posits that pathology results when distressing experiences are processed inadequately and hypothesizes that EMDR accelerates information processing, resulting in the adaptive resolution of traumatic memories.

The relationship between efficacy and methodology in studies investigating EMDR treatment of PTSD.

The controlled treatment outcome studies that examined the efficacy of EMDR in the treatment of posttraumatic stress disorder have yielded a range of results, with the efficacy of EMDR varying across studies. The current study sought to determine if differences in outcome were related to methodological differences. The research was reviewed to identify methodological strengths, weaknesses, and empirical findings.
