Providing a medical definition of concussion improves reliability of self-reported history of concussion in adult former athletes. We examine whether providing a medical definition of concussion to youth athletes increases the number of concussions reported, and whether reporting differs by age, sex, or sport type.
Cross-sectional survey.
Concussion specialty clinic.
Convenience sample of youth athletes (n = 301; mean age = 15.1 ± 1.6 years) presenting for evaluation of sports-related concussion.
Number of concussions reported before and after presentation of the medical definition of concussion ("vignette").
Number of concussions reported after vignette. Paired-sample t test examined for main effect of the vignette on reporting behavior. One-way between-subjects analysis of variance with pairwise comparisons assessed for group differences.
Thirty percent of youth athletes reported an increase in number of concussions after vignette overall (P < 0.000). There was no significant difference in reporting behavior by age, sex, or sport type.
Providing the medical definition of concussion, a simple and brief intervention, gives youth athletes context to understand when a concussion has occurred. This results in an increase in the number of concussions reported when gathering a self-reported history. Reporting behavior after a vignette does not differ across sex, sport type, or age of the athlete.
提供脑震荡的医学定义可提高成年前运动员自我报告脑震荡病史的可靠性。我们研究了向青年运动员提供脑震荡医学定义是否会增加报告的脑震荡次数，以及报告是否因年龄、性别或运动类型而异。
横断面调查。
脑震荡专科诊所。
前来评估与运动相关的脑震荡的青年运动员的便利样本（n=301；平均年龄=15.1±1.6 岁）。
在呈现脑震荡医学定义“小插曲”前后报告的脑震荡次数。
呈现小插曲后报告的脑震荡次数。采用配对样本 t 检验检验小插曲对报告行为的主要影响。采用单向方差分析和两两比较评估组间差异。
30%的青年运动员总体上报告脑震荡次数增加（P<0.000）。报告行为在年龄、性别或运动类型方面无显著差异。
提供脑震荡的医学定义，一种简单而简短的干预措施，使青年运动员能够了解何时发生脑震荡。这导致在收集自我报告病史时报告的脑震荡次数增加。呈现小插曲后，报告行为在性别、运动类型或运动员年龄方面没有差异。
