Clinical Trial Summary

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.

Description:

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Change in Neurobehavioral Symptoms	Between-group magnitude of change in sum score using the self-report measure, Neurobehavioral Symptoms Index (NSI). The scoring range is 0-88. Higher scores indicate more severe neurobehavioral symptoms.	At 3 months and at 6 months
Other	Change in PTSD Symptoms	Between-group magnitude of change in sum score using the self-report measure, PTSD Checklist (PCL-5). The scoring range is 0-80. Higher scores indicate more severe PTSD symptoms	At 3 months and at 6 months
Other	Change in Depressive Symptoms	Between-group magnitude of change in sum score using the self-report measure, Beck Depression Inventory (BDI-II). The scoring range is 0-63. Higher scores indicate more severe depressive symptoms.	At 3 months and at 6 months
Other	Change in Health-Related Quality of Life	Between-group magnitude of change in sum score using the self-report measure, Quality of Life after Brain Injury (QOLIBRI). The scoring range is 0-100. Lower scores indicate lower quality of life.	At 3 months and at 6 months
Other	Change in Executive Function Symptoms	Between-group magnitude of change in After total T-score using the self-report measure, Frontal Systems Behavior Scale (FrSBe). Raw scores are converted to age- and education-corrected T-scores. The mean T-score is 50, scores greater than 65 are considered clinically significant.	At 3 months and at 6 months
Other	Change in Cognitive Symptoms	Between-group magnitude of change in sum score using the self-report measure, Cognitive Failures Questionnaire (CFQ). The scoring range is 0-100. Higher scores indicate more severe cognitive symptoms.	At 3 months and at 6 months
Other	Change in Work/School Status	Change in total score using the self-report questionnaire about their work/school status.	At 3 months and at 6 months
Other	Change in Physical Activity	Change in total score based on weekly self-report dairy about physical activity during training period.	At 3 months
Other	Change in Diet	Change in total score based on weekly self-report dairy about diet during training period.	At 3 months
Other	Change in Social Activity	Change in total score based on weekly self-report dairy about social activity during training period.	At 3 months
Other	Change in Sleep	Change in total score based on weekly self-report dairy about sleep during training period.	At 3 months
Other	Change in Functional Abilities	Change in total score based on weekly self-report dairy about functional abilities during training period.	At 3 months
