Chinese translation and validation of the Sport Concussion Assessment Tool 3 (SCAT3).

Objective: The aim of this study was to translate, adapt and validate the Sport Concussion Assessment Tool 3rd edition (SCAT3), a test for assessing athletes for concussion, into the Chinese context.

Methods: Translation and adaptation were performed in several stages, which included forward translation by two independent teams, translation merging, backward translation, reviews by both native Cantonese-speaking and Mandarin-speaking multidisciplinary expert panels (n=49) for semantic and conceptual equivalence and reviews by pitch-side physiotherapists (n=18) as end-users of the SCAT3 and rugby players (n=11) for face validity. The Serial 3  s subtraction test was used as a substitute for the Months Backward Test (MBT) for measures of concentration in the Standardized Assessment of Concussion subscale.
