Both groups will be assessed in a pre/post intervention design and will be compensated for their time completing study surveys. During the 3 months that they are involved in the study, the intervention group will be sent (via Concussion Coach) reminders to engage with the app on a weekly basis. Their use (e.g., total time spent on each component of the app) will be collected electronically. Both groups will receive care as usual (meaning their regularly scheduled VA appointments and medications). At the completion of the study, both groups will be encouraged to download the App for their own use, with assistance from the study team if needed.
