A grounded theory of youth athlete concussion under-reporting decisions.

Background: Sport-related concussions leave youth vulnerable to significant health, physical, social, and educational disruptions. Many youth athletes under-report concussions, but the scope of the issue for this population is not well understood, nor are the underlying motivations for (under)reporting. It is necessary to examine the relationship between sport-related concussion knowledge and reporting and invite athletes to share their decision-making processes.
