Perceived coach support and concussion symptom-reporting: differences between freshmen and non-freshmen college football players.

This paper examines college athletes' perceived support for concussion reporting from coaches and teammates and its variation by year-in-school, finding significant differences in perceived coach support. It also examines the effects of perceived coach support on concussion reporting behaviors, finding that greater perceived coach support is associated with fewer undiagnosed concussions and returning to play while symptomatic less frequently in the two weeks preceding the survey. Coaches play a critical role in athlete concussion reporting.
