Performance of college athletes on the 10-item word list of SCAT5

Abstract

The Sport Concussion Assessment Tool-5 (SCAT5) was published in 2017; however, normative performance within the college athlete population on the optional 10-item word list has not been described. This study reports normative values for immediate memory trials, total immediate memory score and delayed recall of the 10-item word list. Methods The SCAT5 was administered as part of the preparticipation medical testing to 514 collegiate student-athletes, aged 17-23 (M=19.65, SD=1.40; 64% male) prior to the 2017-2018 athletic season. Results On the SCAT5's optional 10-item word list, with a total possible immediate memory score of 30, participants recalled an average of 20.57 (SD=3.22) words over three learning trials, with an average for trial 3 of 8.13 (SD=1.32). The average delayed memory score was 6.59 (SD=1.85). Small but significant demographic comparisons were found. Women scored higher on both immediate and delayed recall, non-native speakers scored higher on delayed recall, and Black/African-American athletes scored lower than White athletes on immediate, and lower than White and Hispanic/Latino athletes on delayed recall. Conclusion The 10-item word list on the SCAT5 eliminates the ceiling effect observed on the five-item word list of the SCAT3, therefore, increasing its clinical utility in the diagnosis of sports-related concussions. Significant demographic differences suggest use of category-specific norms for sex, native language and race/ethnicity.
