About this trial
Posttraumatic stress disorder (PTSD) and mild TBI (mTBI) frequently co-occur in post-9/11 Veterans, and together are associated with worse cognitive performance, mental health, everyday functioning, community integration, quality of life, and treatment response than either condition alone. Additional comorbidities, such as depression and sleep disturbance, are common and further exacerbate these problems. The investigators will investigate Compensatory Cognitive Training (CCT) and Morning Bright Light Therapy (MBLT) vs Negative Ion Generator (ION), to directly target cognition, depression, and sleep disturbance and to improve CCT-associated rehabilitation outcomes. The investigator's randomized controlled trial in 144 Veterans with mTBI+PTSD across two VA sites will compare cognition, functioning, and other secondary outcomes following CCT+MBLT vs. CCT+ION. This study addresses the significant gap in services and evidence-based treatments for Veterans with mTBI+PTSD.

Trial outcomes
Primary outcomes
Objective Cognitive Performance
Composite z score of Hopkins Verbal Learning Test-Revised; Wechsler Adult Intelligence Scale, Fourth Edition (WAIS-IV) Digit Span; WAIS-IV Coding; Delis-Kaplan Executive Function System (D-KEFS) Trails; D-KEFS Color-Word Interference; and the UCSD Performance-Based Skills Assessment-Brief (UPSA-B). There is no minimum or maximum value of a z score. Higher scores will reflect better outcomes.
Functioning
Composite z score of Brief Inventory of Psychosocial Functioning and the World Health Organization Disability Assessment Schedule 2.0. There is no minimum or maximum value of a z score. Higher scores will reflect better outcomes.
Secondary outcomes
Insomnia Severity Index
Insomnia severity. Scores range from 0-28, with higher scores representing worse insomnia.
Pittsburgh Sleep Quality Index
Sleep quality. Scores range from 0-21, with higher scores representing worse sleep quality.
Total Sleep Time
Total Sleep Time derived from Actiwatch2. Minutes range from 0 to 1440 per day, with higher numbers reflecting more minutes of sleep.
Patient Health Questionnaire-9
Depression symptom severity. Scores range from 0-27, with higher scores reflecting worse depression symptoms.
