Objective: Concussion is a common injury in ice hockey and previous research suggests some misconceptions and unsafe attitudes amongst players. The purpose of this study was to assess sport concussion knowledge, attitudes and the effect of sport concussion history in UK based male ice hockey players across three levels of competition: professional, semi-professional, and amateur. Methods: Sixty-one participants across a number of UK ice hockey teams completed the Rosenbaum Concussion Knowledge and Attitudes Survey (RoCKAS) and reviewed a series of statements to assess knowledge (CKI), attitudes (CAI) and misconceptions of concussion. Results: Level of competition and concussion history had no significant effect on CKI or CAI. A positive significant relationship exists between playing experience and CKI and CAI. Statements identified common misconceptions and areas of accurate knowledge regarding concussion symptoms suggesting that male ice hockey players have a higher-level knowledge compared to a sample of the UK general public. Playing experience was associated with increased knowledge and increasingly safe attitudes towards concussion. Conclusion: Despite knowledge relating to loss of consciousness and correct management of symptoms being generally accurate, there are worryingly unsafe attitudes regarding aspects of concussion. Such attitudes may well pose significant threats to player safety and longterm health.
