Researchers are evaluating accelerated behavioral therapies for military personnel and veterans experiencing insomnia, nightmares, and PTSD. This randomized clinical trial compares cognitive-behavioral therapy for insomnia and nightmares combined with Written Exposure Therapy to a control group receiving sleep hygiene practices integrated with Written Exposure Therapy. The study aims to determine the effectiveness of these treatments in improving symptoms of insomnia, nightmares, and PTSD in this population. Participants are assigned to one of two groups one receiving cognitive-behavioral therapy for insomnia and nightmares CBTin integrated with Written Exposure Therapy WET, and the other receiving sleep hygiene education combined with WET. Both treatments are delivered in an accelerated group format over five days, with individual therapy sessions before and after the group treatment. The study involves 160 participants who will undergo these interventions. During the study, participants will be assessed using various tools including the Posttraumatic Stress Disorder Checklist PCL-5, Insomnia Severity Index ISI, and Nightmare Disorders Index at baseline and through 3- and 6-month follow-ups. Additional evaluations include clinician interviews, anxiety and depression screenings, and psychosocial functioning assessments. The trial monitors changes in symptoms and treatment effects over time, with safety and adherence tracked throughout the study period, which extends through follow-up visits up to six months post-treatment.
