研究了橄榄球联赛中轻度头部损伤对信息处理速度的影响的几个短期测试的敏感性。所用的测量工具是符号数字形态测验、数字符号替代测验和理解速度测验。进行了两项研究，第一项是检查练习的效果，第二项是确定受伤后对认知障碍的敏感性。第一项研究建立了替代形式的等价性，并证明了理解速度和数字符号替换测试的表现随着练习而提高，而符号数字模态测试保持稳定。第二项研究对10名随后遭受轻度头部损伤的球员进行了研究，结果表明，信息处理速度的测量对急性期后的损伤敏感，而不定时的单词识别任务（Spot-the-Word）则不敏感。理解速度比数字符号替代或符号数字模式测试对损伤后损伤更敏感。在受伤前使用较高的分数进行重复的基线评估，以反映球员的潜力，允许在敏感测试中测量受损的表现。
The sensitivity of several short tests of speed of information processing to the effects of mild head injury in rugby league football was investigated. The measures used were the Symbol Digit Modalities Test, the Digit Symbol Substitution Test, and the Speed of Comprehension Test. Two studies were conducted, the first to examine the effect of practice, the second to determine sensitivity to cognitive impairment immediately following injury. The first study established alternate form equivalence and demonstrated that performance on the Speed of Comprehension and Digit Symbol Substitution tests improved with practice, whereas the Symbol Digit Modalities test remained stable. A second study of 10 players who subsequently sustained mild head injuries showed that measures of speed of information processing were sensitive to impairment in the postacute phase, whereas an untimed task of word recognition (Spot-the-Word) was not. Speed of Comprehension was more sensitive to postinjury impairment than either the Digit Symbol Substitution or Symbol Digit Modalities tests. A repeated baseline assessment before injury using the higher score to reflect a player's potential, allowed measurement of impaired performance on sensitive tests.
