BACKGROUND In 2013, the National Academy of Sciences emphasized the need to develop, implement, and evaluate effective large‐scale educational strategies to improve the culture of concussion in youth and high school sports. In support of this recommendation, in this article we summarize research on factors that contribute to the culture of concussion. METHODS We conducted the literature search using 7 electronic databases. We used a scoping review method to identify studies that addressed knowledge, attitudes, behaviors, use of educational resources, and interventions related to concussion among young athletes, coaches, and parents. RESULTS Of the 33 articles identified, most focused on concussion education (N = 15), followed by knowledge (N = 13), behaviors (N = 13), and attitudes (N = 5). Three studies addressed multiple study populations. CONCLUSIONS The rapid spread of concussion education and awareness efforts has outpaced research on effective strategies to improve knowledge, attitudes, and behaviors that contribute to the culture of concussion. Further research is critical to inform the development and implementation of large‐scale educational efforts. This research should incorporate rigorous study designs; be inclusive of diverse ages, socioeconomic status, and racial/ethnic groups; and examine opportunities to improve behavioral outcomes around concussion prevention, reporting, and management.
