Neuropsychological assessments of outcome after traumatic brain injury (TBI) are often unrelated to self-reported problems after TBI. The current study cluster-analyzed the Wechsler Adult Intelligence Scale-Third Edition (WAIS-III) subtest scores from mild, moderate, and severe TBI (n=220) and orthopedic injury control (n=95) groups, to determine whether specific cognitive profiles are related to people's perceived outcomes after TBI. A two-stage cluster analysis produced 4- and 6-cluster solutions, with the 6-cluster solution better capturing subtle variations in cognitive functioning. The 6 clusters differed in the levels and profiles of cognitive performance, self-reported recovery, and education and injury severity. The findings suggest that subtle cognitive impairments after TBI should be interpreted in conjunction with patient's self-reported problems.
神经心理学评估外伤性脑损伤 (TBI) 的结果往往与 TBI 后的自我报告问题无关。本研究对轻度、中度和重度 TBI（n=220）和骨科损伤对照组（n=95）的韦氏成人智力量表第三版（WAIS-III）子测验分数进行了聚类分析，以确定特定的认知模式是否与人们 TBI 后的感知结果有关。两阶段聚类分析产生了 4 个和 6 个聚类解决方案，6 个聚类解决方案更好地捕捉了认知功能的细微变化。这 6 个聚类在认知表现、自我报告的恢复情况以及教育和损伤严重程度方面的水平和模式存在差异。研究结果表明，TBI 后细微的认知障碍应结合患者的自我报告问题进行解释。
