This study aims to compare two active psychological treatments for PTSD. One is an established therapy, Cognitive Processing Therapy (CPT) which operates as a control condition for a newly developed intervention, an integrative Gestalt-based trauma therapy, Dialogical Exposure Therapy (DET). There is no inactive control condition. We expect the two therapies to perform on a similar level, which would constitute evidence for the efficacy of DET.
