Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are current or former members of the uniform services with mild to moderate TBI and chronic insomnia symptoms.
✕Probably not a fit
Patients with significant neurological diseases other than TBI or severe sleep apnea may not benefit from this study.

What this trial studies
This study compares the effectiveness of telemedicine-delivered cognitive behavioral therapy for insomnia (CBT-I) and mindfulness-based treatment for insomnia (MBTI) in treating insomnia and depressive symptoms in adults with mild to moderate traumatic brain injury (TBI) and comorbid post-traumatic stress symptoms. A total of 360 participants will be randomized to receive either CBT-I or MBTI over six sessions, with assessments conducted at baseline, post-treatment, and at 2, 6, and 12 weeks after treatment. The primary outcome will be measured using the Insomnia Severity Index (ISI), while secondary outcomes will include pre-sleep arousal and depressive symptoms. Participants will also wear actigraph monitors and complete electronic sleep diaries throughout the study.
Why it matters
Potential benefit: If successful, this study could provide effective non-pharmacological treatments for insomnia and related symptoms in veterans with TBI.
How similar studies have gone: Previous studies have shown promising results for both CBT-I and mindfulness-based interventions in treating insomnia, suggesting potential success for this approach.
