CBT-I vs. MBTI for Traumatic Brain Injury (TBI)-Related Insomnia and Post-Traumatic Stress Symptoms

This study is a prospective two-arm, randomized single blind controlled trial design to compare the clinical effectiveness of telemedicine-delivered cognitive behavioral therapy for insomnia (CBT-I) and mindfulness-based treatment for insomnia (MBTI) in treating insomnia and ameliorating depressive symptoms in persons with mild to moderate TBI and comorbid symptoms of posttraumatic stress and insomnia. A cohort of n=360 adults with mild to moderate TBI and comorbid symptoms of posttraumatic stress and insomnia will be randomized to receive either telemedicine-delivered CBT-I or MBTI. Consistent with previous scientific literature, the interventions will be standardized and six sessions in length. All participants will wear an actigraph wrist monitor throughout the course of the project. All participants will also complete electronic sleep diaries throughout the course of the project. Participants will undergo assessment (psychosocial questionnaires, neurocognitive testing, sleep diaries, actigraphy, ambulatory EEG sleep monitoring) at baseline, at the end of treatment, and at 2-, 6- and 12-weeks post-treatment (12- and 24-weeks post randomization, respectively). The primary outcome is insomnia severity (ISI) and secondary outcomes are pre-sleep arousal, and depressive symptoms (PSAS; Patient Health Questionnaire (PHQ-8). Exploratory analyses will include neurocognitive functioning (ANAM) and pre-sleep arousal (PSAS).
