Description
This study aims to compare the efficacy and efficiency of Eye Movement Desensitization and Reprocessing (EMDR) and prolonged exposure (PE) in the treatment of posttraumatic stress disorder (PTSD) in adults. Both interventions are standardized treatments for PTSD, however, each intervention’s mechanism of action are different, with EMDR being classified as a bottom-up psychotherapy model and PE being classified as a top-down psychotherapy model. A second aim of this study is to investigate whether differences in treatment response to EMDR compared to PE is moderated by interoception, a person’s ability to be aware of their internal states of their body. To accomplish these goals, a randomized controlled trial will be completed, with participants (adults over 18 meeting DSM-V criteria for diagnosis of PTSD) (N= 300) being randomized to either receive EMDR, PE, or treatment as usual (TAU) for 3 months (weekly sessions, 12 sessions total). Symptoms will be assessed by treatment-blind assessors at posttreatment, and at 3- and 6-months follow-up.

A comparative study of EMDR and prolonged exposure for the treatment of posttraumatic stress disorder: Does interoception moderate differences in symptom reduction?
