About this study
The Investigators have proposed targeted efforts to address the feasibility, effectiveness, fidelity, and evaluation of the GLB-TBI Evidence Based Intervention (EBI) in a real world setting at a CDC-recognized site
Read the detailed description
Despite strong efficacy data, CDC recognition of our modified curricula, and online training modules, efforts to ensure the systematic adoption of our GLB-TBI evidence based intervention (EBI) in real-world settings (i.e., CDC-recognized sites) remain limited, yet are critically needed. The proposed scale-up evaluation trial is an important and logical next step in this systematic line of research to increase the impact and scope of our GLB-TBI EBI. The Investigators have proposed targeted efforts to address the feasibility, effectiveness, fidelity, and evaluation of the GLB-TBI EBI in a real world setting at a CDC-recognized site. Results will provide a scalable EBI that can be implemented at CDC-recognized sites nationally) to improve obesity and cardiometabolic health of people with TBI.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Group Lifestyle Balance for People with TBI (GLB-TBI)Behavioural
The GLB-TBI is a one-year program with 22 sessions. It begins with 12 weekly sessions called the Core Program, followed by a Transition phase consisting of 2 bi-weekly and 2 monthly sessions, and a Support Phase consisting of 6 monthly sessions. The GLB-TBI is a modification of the Diabetes Prevention Program Group Lifestyle Balance (DPP-GLB) with modifications specifically for people with a Traumatic Brain Injury

What is being measured
The primary outcome is the main question the study is designed to answer.
Body Weight
Body weight will be measured at each session using an accessible scale.
Measured: Baseline and 12 months
Secondary outcomes (6)
Blood Pressure
Using an automatic cuff diastolic and systolic scores will be obtained either in person or via Quest Diagnostics.
Measured: Baseline and 12 months
Hemoglobin A1c
Blood sample will be obtained either in person or via Quest Diagnostics.
Measured: Baseline and 12 months
Fasting Blood Glucose
Blood sample will be obtained either in person or via Quest Diagnostics.
Measured: Baseline and 12 months
Lipid Panel
Blood sample will be obtained either in person or via Quest Diagnostics.
Measured: Baseline and 12 months
Self-Efficacy
Self reported measure using the Self-Rated Abilities for Health Practice scale. Measure includes 28 items that assess health practices among people with disabilities and yields a total Health Practices Score plus 4 subscale scores regarding Exercise, Nutrition, Health Practices, and Psychological Well Being. Items are rated on a 5-point scale from 0 'not at all' to 4 'completely.' Scores range from 0-28 with higher scores indicating higher exercise self-efficacy.
Measured: Baseline and 12 months
Exit Survey
Participants will be asked to complete Exit Survey at the 12-month assessment. This survey will ask about participant experience in, and satisfaction with, the GLB-TBI program and suggestions for improvement.
Measured: 12 months

Questions about this trial
What is this clinical trial studying?
An observational study of Traumatic Brain Injury and Brain Injuries, Traumatic, run by Baylor Research Institute at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 16 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Alexandria Suhalka, MPH (214-865-2496, Alexandria.Suhalka@BSWHealth.org), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Body Weight (time frame: Baseline and 12 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Jun 2026.
