The performance of 40 children with complicated mild to severe traumatic brain injury on the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV; Wechsler, 2003) was compared with that of 40 demographically matched healthy controls. Of the four WISC-IV factor index scores, only Processing Speed yielded a statistically significant group difference (p < .001) as well as a statistically significant negative correlation with length of coma (p < .01). Logistic regression, using Processing Speed to classify individual children, yielded a sensitivity of 72.50% and a specificity of 62.50%, with false positive and false negative rates both exceeding 30%. We conclude that Processing Speed has acceptable criterion validity in the evaluation of children with complicated mild to severe traumatic brain injury but that the WISC-IV should be supplemented with other measures to assure sufficient accuracy in the diagnostic process.
将40名患有复杂轻至重度创伤性脑损伤的儿童在韦氏儿童智力量表第四版(WISC-IV;韦克斯勒,2003年)上的表现与40名人口统计学匹配的健康对照组儿童进行了比较。在WISC-IV的四个因素指数得分中,只有加工速度产生了统计学上显著的组间差异(p <.001),并且与昏迷时长存在统计学上显著的负相关(p <.01)。使用加工速度对个体儿童进行分类的逻辑回归分析得出,灵敏度为72.50%,特异度为62.50%,假阳性率和假阴性率均超过30%。我们得出结论,加工速度在评估患有复杂轻至重度创伤性脑损伤的儿童时具有可接受的效标效度,但在诊断过程中,应补充其他测量方法以确保WISC-IV具有足够的准确性。
