Nightmares

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 goal of this randomized controlled trial is to pilot the virtual delivery of cognitive behavioral therapy for insomnia (CBT-I) and nightmares (CBT-I\&N) via telehealth as an early intervention for treating posttraumatic sleep disturbance in acute trauma patients exposed to interpersonal violence. The main aims are to: 1. Test the acceptability, feasibility, and satisfaction of sleep-focused CBT delivered early after trauma 2. Evaluate the impact of sleep-focused CBT delivered early after trauma on sleep disturbance 3. Evaluate the impact of sleep-focused CBT delivered early after trauma on PTSD symptoms The investigators will compare CBT-I and CBT-I\&N to sleep education control. Participants will meet with a provider for 6 weekly sessions via telehealth and complete surveys on the participants' symptoms.

Exposure, relaxation, and rescripting therapy (ERRT) is a promising psychological intervention developed to target trauma-related nightmares and sleep disturbances. Though further evidence is needed, ERRT has shown strong support in reducing the number and intensity of nightmares, as well as improving overall sleep quality in both civilian and veteran samples. This study will assess the efficacy in individuals diagnosed with bipolar disorder.
