About this trial
The overall goal of this Phase IIa randomized controlled pilot trial is to assess the potential efficacy of two emerging treatments for post-trauma nightmares and to test the feasibility of study design and methods. Symptom change will be assessed in two treatment arms: (1) Nightmare Deconstruction and Reprocessing (NDR), an exposure-based psychotherapy; and (2) NightWare (NW), a non-exposure approach using a wristband device. The investigators will also assess the feasibility of circadian-dependent blood sampling and use of another wristband to collect physiologic data. Specific aims are: (1) Compare evidence of how well participants tolerate and comply with the two treatments and test feasibility of methods and procedures; (2) Collect additional evidence of the potential efficacy of two contrasting non-pharmacologic approaches to treating posttraumatic nightmares; (3) Explore the operational stress index (OSI) as a reliable, objective measure of sleep disturbance and nightmare events.

Trial design
Parallel
Treatments tested in this trial
Nightmare Deconstruction and Reprocessing
BehavioralA psychotherapy that uses exposure to nightmare images for trauma activation in order to facilitate trauma memory reconsolidation
NightWare
DeviceWristband device that detects physiologic signals during sleep that indicate a possible nightmare and gently vibrates to rouse the sleeper without fully waking them.
Treatment groups
Trial outcomes
Primary outcomes
Disturbing Dreams and Nightmare Severity Index
The DDNSI is a 5-item self-report instrument used to assess nightmare severity and distress both as an inclusion criterion (score ≥10) and as a primary study variable. Possible score range is 0-37, with a recommended cutoff of 10.
Insomnia Severity Index
The ISI is a 7-item self-report measure that assesses not only perceived severity of insomnia with regards to difficulty falling and staying asleep, but also daytime dysfunction. Possible score range is 0-28, with a recommended cutoff of 8 for sub-threshold insomnia.
Secondary outcomes
Operational Stress Index (OSI)
The OSI uses physiological data (heart rate, heart rate variability, skin temperature, movement) to identify stress responses, which may allow researchers to reliably recognize sleep disturbance and nightmare events.
Brain-derived neurotrophic factor (BDNF) levels before and after exposure
Cortisol levels before and after exposure
Adrenocorticotropic hormone (ACTH) levels before and after exposure
