Integrated CBT-I and PE on Sleep and PTSD Outcomes (Impact Study)

Integrates CBT-I and PE with the goal of enhancing both insomnia and PTSD outcomes. Integrated treatment will be delivered in 14 90-minute weekly sessions. CBTI-PE starts with VA rollout CBT-I for the first 3 weeks with a focus on the effects of PTSD on insomnia. PE protocol (psychoeducation) begins on week 4 of treatment and both treatments overlap till week 6 when CBT-I ends and the active treatment of PE begins (i.e., imaginal and in-vivo exposures). However, CBT-I sleep diary review and sleep time adjustment will continue till the end of treatment to increase adherence

The investigators have included a non-active sleep control arm (3 Sessions)to allow for the dose response of 14 90 minute sessions. The non-active sleep control condition used in this study is a manualized protocol developed to exclude the active components of standard CBT-I treatment. Hygiene includes presentation of sleep hygiene education and reviewing daily stressors that may impact sleep before starting PE on week 4.
