Self-reported concussion history among Icelandic female athletes with and without a definition of concussion

Abstract

Objective

This study examined whether Icelandic female athletes in contact sports, based their self-reported concussion history on adequate medical definitions, by assessing self-reported concussion history with and without a definition of concussion. Another aim was to examine whether currently active athletes were more knowledgeable of concussions than retired athletes.

Methods

Participants (age = 26.9, SD = 7.1) were 508 former (34.5%) and current (65.5%) elite female athletes in soccer (41%), handball (30.6%), basketball (19.1%), ice hockey (4.5%) and combat sports (4.7%). An online questionnaire (QuestionPro) was distributed to females in contact sports (snowball sampling). Participants later came for an in-person interview where the authenticity of previous responses was confirmed. In the questionnaire, participants answered background questions and questions about concussion history. First, they reported the total number of sustained concussions without a prompt. They reported the number of sustained concussions again after reading a definition of concussion. Participants could not correct their previous answers. Pearson’s Chi-square was used for group comparisons.

Results

The prevalence of reported concussions increased from 40.2% to 64.8% following a definition. There was no significant difference in how many participants changed their answer when asked about sustaining SRCs before and after reading the definition based on whether the participants were still competitive or retired X²(1) = 0.69, p = 0.41.

Conclusions

Our data suggest that understanding of concussions is inadequate among female athletes. Self-report will continue to be an essential source of clinical information and prompting with a definition can increase the reliability of self-reported concussions.
