The performance of 100 patients with traumatic brain injury (TBI) on the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) was compared with that of 100 demographically matched neurologically healthy controls. Processing Speed was the only WAIS-IV factor index that was able to discriminate between persons with moderate-severe TBI on the one hand and persons with either less severe TBI or neurologically healthy controls on the other hand. The Processing Speed index also had acceptable sensitivity and specificity when differentiating between patients with TBI who either did or did not have scores in the clinically significant range on the Trail Making Test. It is concluded that WAIS-IV Processing Speed has acceptable clinical utility in the evaluation of patients with moderate-severe TBI but that it should be supplemented with other measures to assure sufficient accuracy in the diagnostic process.
将100例创伤性脑损伤（TBI）患者在韦氏成人智力量表第四版（WAIS-IV）上的表现与100名人口统计学匹配的神经健康对照者进行了比较。处理速度是WAIS-IV唯一能够区分中度至重度TBI患者与轻度TBI患者或神经健康对照者的因子指数。在区分TBI患者在连线测验中是否有临床显著范围内的得分时，处理速度指数也具有可接受的敏感性和特异性。结论是，WAIS-IV处理速度在评估中度至重度TBI患者时有可接受的临床效用，但在诊断过程中应辅以其他措施以确保足够的准确性。
