Korean Translation and Cross-Cultural Adaptation of the Sport Concussion Assessment Tool 6th Edition (SCAT6): Reliability and Validity

Abstract

PURPOSE: This study aimed to establish a contemporary, standardized Korean version of the Sports Concussion Assessment Tool 6th edition, characterized by superior face validity and reliability. METHODS: Translation and cultural adaptation involved seven stages, namely initial translation, integration of translation, back translation, validation with five expert committees, pre-testing with 12 rugby athletes, finalization, and a test-retest with 30 rugby and American-football athletes. Alternative tests were conducted for the Months In Reverse Order Test due to the naming differences between English and Korean. RESULTS: The English Months In Reverse Order Test took 11.00±2.69 seconds with a difficulty of 2.27±0.98 points, while the Korean Months In Reverse Order Test took 5.69±1.35 seconds with a difficulty of 1.50±0.73 points (p.05). The face validity was adequate and reliability was mostly high (Cronbach alpha=0.79). CONCLUSIONS: The results indicate that The Korean Sports Concussion Assessment Tool 6th edition was well translated and exhibited adequate face validity and reliability.
