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.
The SCAT5 was administered as part of the preparticipation medical testing to 514 collegiate student-athletes, aged 17-23 (=19.65, =1.40; 64% male) prior to the 2017-2018 athletic season.
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 (=3.22) words over three learning trials, with an average for trial 3 of 8.13 (=1.32). The average delayed memory score was 6.59 (=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.
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.
《运动性脑震荡评估工具第5版》（SCAT5）于2017年发布；然而，尚未描述大学生运动员群体在可选的10个单词列表上的正常表现。本研究报告了10个单词列表的即时记忆试验、即时记忆总分和延迟回忆的正常值。
在2017 - 2018赛季体育赛事前，对514名年龄在17 - 23岁（平均年龄 = 19.65岁，标准差 = 1.40；64%为男性）的大学生运动员进行了SCAT5测试，作为参赛前医学检查的一部分。
在SCAT5的可选10个单词列表中，即时记忆总分最高可达30分，参与者在三次学习试验中平均回忆出20.57个（标准差 = 3.22）单词，第三次试验的平均回忆数为8.13个（标准差 = 1.32）。延迟记忆的平均得分为6.59（标准差 = 1.85）。发现了一些虽小但具有统计学意义的人口统计学差异。女性在即时回忆和延迟回忆上得分更高，非母语者在延迟回忆上得分更高，黑人/非裔美国运动员在即时回忆上得分低于白人运动员，在延迟回忆上得分低于白人和西班牙裔/拉丁裔运动员。
SCAT5上的10个单词列表消除了在SCAT3的5个单词列表上观察到的天花板效应，因此，提高了其在诊断与运动相关脑震荡中的临床实用性。显著的人口统计学差异表明，应针对性别、母语和种族/民族使用特定类别的标准值。
