Prolonged vs. “dosed” exposure for PTSD: A pilot study


Prolonged exposure and eye movement desensitization and reprocessing (EMDR) are two empirically validated treatments for posttraumatic stress disorder (PTSD). EMDR has several treatment components and findings from dismantling studies indicate that portions of the treatment can be removed without detrimental effects on treatment outcome. The treatment component that has not been tested in a dismantling study is the form of exposure utilized (i.e., “dosed” exposure). This study compared the efficacy and efficiency of prolonged exposure and a dismantled version of EMDR, here labeled “dosed” exposure, for individuals diagnosed with PTSD. The treatments are compared in terms of the participant’s progress, as well as the rate of treatment response. Initial findings from this study will be presented and discussed.
