Nightmares are one of the most troubling features of posttraumatic stress disorder (PTSD), yet imagery rehearsal training (IRT) is currently the only empirically supported treatment for posttraumatic nightmares. Although IRT is effective, it is unknown whether IRT or the exposure, which is inherent in this procedure, causes the decrease in nightmares. This study will attempt to clarify this issue by using exposure therapy alone to treat a patient with PTSD. The participant is a 39-year-old male who experienced a single traumatic event. Data were collected on his sleep habits, as well as on the frequency and intensity of the nightmares. Results indicate that exposure-based nightmare treatment for PTSD sufferers should be considered in conjunction with standard treatment packages.
