Because of limitations in current national data sets, respondent self-report may be critical to obtaining concussion
prevalence estimates. We examined whether self-report of lifetime concussion
among adults varies with the provision of a concussion
definition and by the content of that definition.
Setting and Participants:
A convenience sample of 6427 American adults who participated in the 2018 Porter Novelli SpringStyles survey.
Frequency of self-reported concussion
by variation in concussion
A quarter of respondents (28.9%) reported experiencing a concussion
in their lifetime. While concussion
prevalence varied by demographic characteristics, it did not vary significantly by concussion
definition. Variation in concussion
definition did not result in differences related to recency of last concussion
, mechanism of injury, or respondent activity engaged in during which they sustained their most recent concussion
The current study suggested that in this sample of adults, the percentage reporting a concussion
did not significantly vary by whether a concussion
definition was provided or by the content of the definition. However, research suggests that prompting about mechanism of injury, listing symptoms individually, and considering only athletic populations may affect estimates and these factors should be included in future question comparisons.
