Home-Based, Online, Mindfulness and Cognitive Training for Soldiers and Veterans With TBI

This study is a parallel arm, double-blind, randomized, controlled clinical trial to assess the safety and efficacy of an experimental software program designed to improve cognitive functions versus a computer-based software control. Both the study and the software being investigated meet the criteria of Non-Significant Risk.

The primary objective of this study is to evaluate the effects of combination of mindfulness training (MT) and adaptive cognitive training (CT) on the cognitive abilities, functional status and quality of life of soldiers and veterans diagnosed with traumatic brain injury (TBI, also referred to as a concussion, or blast exposure), as compared to a computer-based control.

Eligibility Criteria:
Inclusion Criteria:

* Participants must be 18 years of age or older
* Participants must have diagnosis of mild traumatic brain injury (mTBI) confirmed by Ohio State University TBI Identification Method-Short Form (OSU TBI-ID-SF)
* Participants must have persistent cognitive dysfunction confirmed by an objective measure (Automated Neuropsychological Assessment Metrics (ANAM) TBI Battery with a score at least one standard deviation below the age-adjusted norm for a military sample) or a subjective measure (Ruff Neurobehavioral Inventory (RNBI) with a score of greater than 70 on any of the four cognitive scales (Attention, Memory, Language, Executive)
* Participants must be at least six months out from their most recent traumatic brain injury (TBI), concussion, and/or blast exposure
* Participant must be a fluent English speaker
* Participants must score ≥ 70 on the Wechsler Test of Adult Reading (WTAR)
