Accelerated Treatment for Co-occurring Insomnia, Nightmares, and PTSD: A Randomized Controlled Trial
This study is a two-arm individually randomized group treatment clinical trial evaluating behavioral therapies for insomnia, nightmares, and PTSD. The study will compare cognitive-behavioral therapy for insomnia and nightmares to sleep hygiene (Control), both integrated with Written Exposure Therapy for PTSD and delivered in an accelerated (i.e., 5-day) group treatment format, preceded and followed by individual treatment sessions. 160 participants will be randomized into one of two study conditions.
• Defense Enrollment Eligibility Reporting System (DEERS) eligible active-duty military personnel or veteran, 18-65 years old.
• Ability to speak and read English.
• Clinically significant PTSD symptoms (CAPS-5 \> 25 with at least one Intrusion symptom and at least one Avoidance symptom).
• Clinically significant symptoms of insomnia disorder (Structured Clinical Interview for Sleep Disturbance DSM-5 (SCISD) Insomnia Criteria are met and Insomnia Severity Index (ISI) \> 11).
• Nightmares \> 1 monthly (as reported on the SCISD).
• Willing to refrain from new behavioral health or medication treatment for issues pertaining to PTSD, sleep, and nightmares during study participation.
