Treating Co-Morbid Sleep Difficulties in Veterans With Posttraumatic Stress Disorder (PTSD): A Pilot Study

Study Summary

A substantial number of US Veterans are suffering from Posttraumatic Stress Disorder (PTSD) following deployment in recent military conflicts, and sleep disturbance is a primary complaint of Veterans presenting to the VA with PTSD. Veterans with PTSD have more self-reported and physician-rated health problems, and health status is associated with PTSD symptom severity. Most Veterans meeting criteria for PTSD report difficulty initiating or maintaining sleep (70-91%), and increased PTSD severity is associated with increased sleep disturbance. Even after receiving treatment for PTSD, Veterans continue to experience residual insomnia at a rate of about 50%, in spite of having achieved PTSD remission. There are currently no PTSD-specific sleep interventions available, excepting an intervention that is specific to nightmares. Given the prevalence of sleep disturbance in Veterans with PTSD, the absence of interventions for PTSD-related sleep problems, and the increasing number of post-deployment Veterans with trauma-related sleep difficulties, such interventions are desperately needed. In this study, we will test the effectiveness of a multi-component cognitive-behavioral sleep intervention for PTSD that targets both nightmares and insomnia for improving the overall sleep experience of Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF) Veterans with PTSD who are also receiving usual care. The primary objective is to pilot test the intervention for efficacy in reducing sleep disturbance. The secondary objective is to examine the relative impact of the intervention on PTSD symptoms. The project is a prospective, randomized, clinical intervention trial. Participants will be randomly assigned to a multi-component cognitive-behavioral sleep intervention for PTSD + Usual Care, or Usual Care alone. We are hypothesizing that 1) Veterans receiving the sleep intervention plus usual care will produce greater improvements (reduced total wake time, increased sleep eff

Primary Outcome

Insomnia severity was assessed using the Insomnia Severity Index (ISI). The ISI is a 7-item questionnaire that provides a global measure of perceived insomnia severity. Each item is rated on a 5-point Likert scale, and the total score ranges from 0-28. The following guidelines are recommended for interpreting the total score: 0-7 (no clinical insomnia), 8-14 (subthreshold insomnia), 15-21 (insomnia of moderate severity), and 22-28 (severe insomnia). The ISI was used to determine treatment eligib
