The performance of 65 patients with complicated mild-severe traumatic brain injury was evaluated on the Verbal and Design Fluency subtests of the Delis-Kaplan Executive Function System (D-KEFS), and compared with that of 65 demographically matched healthy controls. There were statistically significant group differences on Letter Fluency and Category Switching but not on any of the Design Fluency tasks. Combined, these two Verbal Fluency subtests had a classification accuracy of 65.39%, associated with a likelihood ratio of 1.87. The impact of length of coma on Letter Fluency performance but not Category Switching was mediated at least in part by processing speed. The findings suggest modest criterion validity of some of the D-KEFS Verbal Fluency subtests in the assessment of patients with complicated mild-severe traumatic brain injury.
对 65 例复杂轻-重度创伤性脑损伤患者的表现进行了评估，使用的是 Delis-Kaplan 执行功能系统（D-KEFS）的言语流畅性和设计流畅性子测验，并与 65 名年龄匹配的健康对照组进行了比较。在字母流畅性和类别转换上，两组存在统计学显著差异，但在任何设计流畅性任务上均无差异。这两个言语流畅性子测验结合起来，分类准确率为 65.39%，优势比为 1.87。昏迷时间对字母流畅性表现的影响，但不是类别转换的影响，至少部分是由处理速度介导的。研究结果表明，D-KEFS 言语流畅性子测验中的某些测验在评估复杂轻-重度创伤性脑损伤患者时有一定的标准效度。
