Direct therapeutic exposure
Direct Therapeutic Exposure (DTE) is a behavior therapy technique pioneered by Patrick A. Boudewyns, where stressors are vividly and safely confronted to help combat veterans, and patients suffering from posttraumatic stress disorder (PTSD), panic disorder, or phobias. Exposure therapy has supporting evidence with both simple and complex traumas. A similar therapy is Eye Movement Desensitization and Reprocessing (EMDR).
