A quasi-experimental repeated measure design was used to investigate the effect of an online concussion education program on the knowledge retention among 37 high school football coaches over a 15-week period and whether any variables can successfully predict knowledge retention. Data were collected immediately following an online concussion education program and post 15-weeks using a valid and reliable concussion assessment tool consisting of three distinct subsections: signs and symptoms recognition, common concussion misconceptions, and scenario-based question. A 2-tailed dependent samples t-test was conducted to test knowledge retention, while a multiple linear regression analysis was performed to assess which coaching characteristics and school attributes affect knowledge retention.

Results indicated that the high school football coaches had significantly lower overall as well as signs and symptoms subsection scores on 15-week follow-up assessments compared to post-course assessments, but the participants did not have significantly lower misconception or scenario subsection scores. Coaches’ age, experience, level of education, school size or access to a full-time certified athletic trainer did not significantly influence knowledge retention in this study. This study confirms the need to continue to assess long-term outcomes to assure knowledge retention in high school football coaches after online concussion education
