Secondary Outcomes (3)

  • Insomnia Severity Index (ISI)

    Week 0, Week 5, Post-Treatment, 3-Month Follow-Up, 6-Month Follow-Up

  • Clinician-Administered PTSD Scale for DSM-4 Distressing Dream Score (CAPS-4 Nightmare Item)

    Week 0, Week 5, Post-Treatment, 3-Month Follow-Up, 6-Month Follow-Up

  • Clinician-Administered PTSD Scale for DSM-5 (CAPS-5)

    Week 0, Post-Treatment, 3-Month Follow-Up, 6-Month Follow-Up

Study Arms (2)

Arm 1: Experimental

EXPERIMENTAL

Behavioral: TranS-C for PTSD

Arm 2: Active Control

ACTIVE COMPARATOR

Participants receiving sleep psychoeducation control.

Behavioral: Sleep Psychoeducation Control

Interventions

The Transdiagnostic sleep and circadian intervention (TranS-C), developed by Allison Harvey, Ph.D. and Daniel Buysse, M.D., involves a patient-centered, module-based, flexibly structured approach that tackles numerous sleep disturbances using evidence-based strategies with the goal of improving sleep and related impairments in daytime functioning. It is thus well-suited for tackling sleep disturbances and the associated impairments in social, occupational and overall functioning in veterans with PTSD. The proposed study is a randomized, controlled clinical trial examining the effectiveness of a modified TranS-C intervention for veterans with PTSD. The modified approach, TranS-C for PTSD (TSC-PTSD), elevates the importance of nightmare-focused, apnea-focused, and insomnia-focused modules relative to the standard intervention, incorporates an evidence-based relaxation module, and modifies the nightmare and apnea modules based on strategies used for veterans in the VA healthcare system.

Also known as: TSC-PTSD
Arm 1: Experimental

Participants will receive psychoeducation about sleep.

Also known as: SPC
Arm 2: Active Control

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • U.S. Military Veteran aged 18 and above engaged in VA primary and/or mental health care
  • CAPS 5 PTSD diagnosis; or CAPS 5 score \>=25 in the absence of full criteria
  • SCID Insomnia Disorder diagnosis, supported by ISI score \>=10
  • CAPS-IV nightmare score \>=4
  • Sleep-related functional impairment based on a WHODAS score \>=32
  • Willingness to engage in 8-12 sessions of treatment to address their sleep disturbance

You may not qualify if:

  • Current cognitive problems, active psychosis or mania, or other mental/cognitive conditions such as moderate to severe neurodegenerative disease that would render the participant unable to connect to videoconferencing platform, engage in remote psychotherapy, or communicate using the required VA secure email platform
  • No access to reliable internet service connected to a computer, iPad or similar device (telephone not adequate)
  • Inability or unwillingness to use a VA-approved videoconferencing platform and VA secure email;
  • Current engagement in a sleep-focused psychotherapy, or plan to start a sleep-focused psychotherapy in the next 3 months. Sleep-focused psychotherapies include, but are not limited to, CBT-I, BBT-I, and IRT

Model Details: The study involves a randomized, controlled, single-blind trial to evaluate the effectiveness of TranS-C modified for Veterans with PTSD (TSC-PTSD) in male and female Veterans who are enrolled in primary and/or mental health care in the VA system. Study treatment will be implemented remotely via live video visits using a VA-approved platform. Enrolled participants will be randomly assigned to the TSC-PTSD group or to the sleep psychoeducation control (SPC) group.
