Public Chronic Traumatic Encephalopathy Knowledge: Sources, Accuracy and Confidence.

Abstract: The goal of this study was to examine the general public's level of accuracy and confidence in knowledge of chronic traumatic encephalopathy (CTE), as well as information sources. This study also explored how these factors affected comfort in allowing children to play a high-contact sport. This study utilized online surveys and included 529 participants. Overall, CTE knowledge accuracy was 48.02% (standard deviation = 0.23). Inaccuracies regarding the etiology and diagnosis of CTE were most common, whereas the symptoms and lack of treatments for CTE were more widely known. Despite overall low CTE knowledge accuracy, CTE knowledge confidence was positively correlated with comfort in allowing children to play a high-contact sport (r = 0.199, P ≤ 0.001). Participants identified television/movies followed by web sites and social media as the most utilized CTE information sources. These results further support the need for clinicians and researchers to address misconceptions about CTE.
