28 brain-damaged males ranging in age from 8 to 16 yr. were compared with 28 nondamaged matching controls on their Symbol Digit Modalities Test performance. The damaged group performed significantly more poorly, and 75% of the subjects scored more than .5 z score below their matched controls. The results suggest that this brief and objective test can be used to screen brain-damaged children when their performance is compared to that of a control group or the normative group.
将28名年龄在8至16岁之间的脑损伤男性与28名与之匹配的未受损对照组在符号数字模态测试中的表现进行了比较。受损组的表现明显更差，75%的受试者得分比其匹配对照组低超过0.5个标准分数。结果表明，当将脑损伤儿童的表现与对照组或常模组进行比较时，这种简短而客观的测试可用于筛查脑损伤儿童。
