An interventional study of Cognitive-Behavioral Therapy for Insomnia (CBTi) and Cognitive Behavioral Therapy for Nightmares (CBTn) in Insomnia, PTSD - Post Traumatic Stress Disorder and Nightmares, sponsored by Palo Alto Veterans Institute for Research. Recruiting at 1 site in United States. Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2025-12-03.
Sponsored by Palo Alto Veterans Institute for Research · Not applicable, Interventional, and Treatment
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.
The aims of the study are:
Exploratory Aim: Determine the efficacy of accelerated CBTi+n integrated with WET for improving PTSD symptoms among military personnel with clinically significant symptoms of insomnia, nightmares, and PTSD.
Exclusion Criteria:
Behavioral: Written Exposure Therapy (WET) · Behavioral: Sleep Hygiene
Behavioral: Cognitive-Behavioral Therapy for Insomnia (CBTi) · Behavioral: Cognitive Behavioral Therapy for Nightmares (CBTn) · Behavioral: Written Exposure Therapy (WET)
CBTi focuses on stimulus control, eliminating maladaptive coping habits, reducing arousal, and challenging maladaptive thoughts about sleep in an effort to reduce time to fall asleep and time awake during the night.
CBTn involves writing about a distressing or frequent nightmare, rewriting the narrative of the nightmare to target trauma-related themes, and reading the rescripted nightmare narrative.
WET is a trauma-focused intervention in which individuals write about their worst traumatic experience following scripted instruction from the therapist.
Involves reviewing sleep diary data, sleep education, and reviewing and discussing sleep hygiene practices.
