An interventional study of Goal Management Training and Attention Training in Mild Traumatic Brain Injury, sponsored by VA Office of Research and Development. Completed at 1 site in United States. Open to participants aged 19 Years to 55 Years. Per ClinicalTrials.gov, last updated 2024-08-30.
Sponsored by VA Office of Research and Development · Not applicable, Interventional, and Treatment
Veterans with mild traumatic brain injury continue to deal with symptoms that interfere with their ability to engage in productive activities. In combination with other psychosocial difficulties, impairments are found in cognition, such as attention and executive function. Few interventions are available to treat attention in Veterans with mTBI. Of the interventions available, none rigorously train attention combined with strategy training. This project will innovatively combine a strategy training called Goal Management Training with computerized attention training to improve tests of problem solving, attention and functional tasks compared to a control group.
This is a pilot study to test the effect of GMT plus Attention Training for Veterans with chronic mTBI. The research design is a parallel study with randomization to treatment or control with test administration at pre/post and six months following treatment. The investigators will enroll 50 Veterans with a diagnosis mTBI between the ages of 18 to 55, that demonstrate a deficit in attention, pass effort testing and have not changed psychotropic medication within the past two weeks. Treatment utilizes GMT for 10-weekly two-hour sessions and Brain HQ/Attention Process Training III for 10-weekly two-hour sessions. Control utilizes a complimentary Brain Health Workshop for 10-weely two-hour sessions and National Geographic movies for 10-weekly two-hour sessions.
Aim 1: Determine the treatment effect of attention training combined with GMT in Veterans with mTBI.
Hypothesis 1: GMT plus attention training will significantly improve performance on tests of cognition compared to the control group.
Primary measure: Computerized Tower of London (cTOL) total time, time to first move and optimal moves). The investigators have found significant improvement in cTOL following GMT in previous cohorts of Veterans with blast-related mTBI and anticipate improvement following a combined intervention.
Secondary measure: Attention Network Task (ANT) reaction time and errors for one or all dissociable components of three attentional systems (orienting, alerting, executive control) following intervention. There is little understanding of components of impaired attention and how it impacts executive function; therefore, there is limited guidance in shaping cognitive training. The investigators will conduct an experimental task (attention network task) that disassociates three attentional components (alerting, orienting, and executive control). The investigators will specifically target the orienting component of attention that is problematic for Veterans with mTBI and PTSD24, 26. Attentional processes are vital to goal-directed behavior. There is great potential in the use of these measures to identify individual differences (type of attention deficit) that could moderate treatment-related improvement and inform targeted interventions.
Hypothesis 2: Treatment gains will translate to functional activities compared to controls.
Primary measure of functional performance: test of grocery shopping skills (TOGSS) total time and optimal strategy use. The TOGSS captures efficiency in completing a real-world task and aligns with the strategy skills learned in GMT.
Secondary measure of community participation, the Community Reintegration of Servicemembers (CRIS) extent of participation. The CRIS demonstrated significant GMT treatment effect compared to controls in Veterans with mTBI. The combined treatment of attention training using drill training and implementing strategies to improve attention in a functional setting through GMT will potentiate treatment effect to functional activities. Measuring functional improvement through performance-based measures and self-report of engagement in activities will demonstrate treatment translation.
Tertiary analysis will be conducted on moderator variables: PTSD symptoms, Pain, History of Substance Abuse, Depression, number of concussions and combat exposure.
Successful completion of the proposed study will provide insight into the effectiveness of the innovative combined treatment of attention and executive function in Veterans with mTBI and PTSD. Use of the ANT could better target treatment and lead to future examination of attention treatment on neuroplasticity.
A multiple linear regression model will be used to determine if there is a significant association between treatment effect and comorbidities such as PTSD, depression, anxiety, pain, sleep, substance abuse, etc.

Exclusion Criteria:
GMT consists of 2-hour, 10 weekly sessions using an interactive Power Point presentations. Attention training consists of 2-hour computerized attention training using Attention Process Training III and Brain HQ.
Behavioral: Goal Management Training · Behavioral: Attention Training
Brain Health Workshop consists of 2-hour, 10 weekly sessions using Power Point presentations and national geographic movies (2-hour, 10 weekly sessions).
Behavioral: Brain Health Workshop · Behavioral: National geographic movies
GMT: is a 10-session intervention to improve planning and problem solving. Interactive Power Point modules are administered by a cognitive therapist. Each session builds on the steps of a five-stage planning and problem-solving strategy. Veterans will be taught to generate and verbalize the following five-steps: "stop-what am I doing?", "define the goal", "list the steps", "learn the steps"; then, "check-am I doing what I planned?" The five-stage strategy is then incorporated into a variety of activities in the laboratory and in-home assignments.
Also known as: GMT
Attention Process Training (APT-III) will be administered for a second weekly session in addition to the GMT session. Each session will be 2 hours/ week for 10 weeks. Veterans will also engage in BrainHQTM attention training at home for one-hour, five days/ week comprised of selected components of BrainHQ from Posit Science Corporation. This web-based computerized CRT modality of cognitive training is a restorative or "bottom-up" approach that targets basic cognitive skills such as arousal and vigilance processes, attention and information processing, and directly engages fundamental attention-control skills through repetitive graded exercises.
Also known as: APT III, Brain HQ
. BHW was developed specifically for consistency with GMT session length and contact with the facilitator49. BHW is an education presentation on brain function and cognitive principles of learning with homework and quizzes on information covered. To match time and contact of attention training, control participants will meet with the therapist for a separate two-hour session from BHW
Also known as: BHW
participants will select movies to watch and answer a few questions about to equate the time and therapist interaction to attention training in arm 1.

Attention Network Task
Flanker task that dissociates attention into three components: alerting, orienting and executive control. Attention network effects were calculated using the following mean response time (RT) subtractions: alerting effect = no-cue RT minus center cue RT; orienting effect = invalid spatial cue RT minus valid spatial cue RT; executive control (conflict) effect = incongruent RT minus congruent RT. Mean response time for week 1, week 11 and week 36 on each component., lower=better performance.
Time frame: week 1, 11, 36
Community Reintegration of Service Members
