Abstract

Objective

We sought to determine the accuracy of embedded performance measures for the D–KEFS Color Word Interference Test that were recently proposed by Eglit et al. In particular, we wanted to determine if these indices would be associated with a specificity of at least .90, an Area Under the Curve of at least .70 and a positive likelihood ratio of at least 2. Method: We used logistic regression to investigate how well these indices could distinguish persons with traumatic brain injury (n = 169) who were evaluated within 1-12 months after injury. All participants had been classified on the basis of at least three independent performance validity tests as valid performance (n = 145) or invalid performance (n = 24). Results: None of the three indices that Eglit et al. had proposed as embedded performance measures for the D–KEFS Color Word Interference Test achieved the a priori defined minimally acceptable level of specificity. One of them did meet the criteria for Area Under the Curve as well as positive likelihood ratio. Conclusion: The current results do not support the application of the Eglit et al. embedded performance validity measures for the D–KEFS Color Word Interference Test in the clinical evaluation of patients with traumatic brain injury.

D–KEFS颜色词干扰测试作为创伤性脑损伤后表现效度的嵌入式衡量指标

摘要

目的

我们试图确定Eglit等人最近提出的D–KEFS颜色词干扰测试的嵌入式性能度量的准确性。特别是，我们想确定这些指数是否与至少0.90的特异性，至少0.70的曲线下面积以及至少2的正似然比相关。方法：我们使用逻辑回归研究这些指数如何区分脑外伤 患者（n = 169），这些人在受伤后1至12个月内接受了评估。根据至少三个独立的绩效有效性测试将所有参与者分类为有效绩效（n  = 145）或无效绩效（n  = 24）。结果：Eglit等人没有这三个指数。D-KEFS颜色词干扰测试的嵌入式性能指标已达到先验定义的最低可接受性。其中一个确实符合“曲线下面积”和正似然比的标准。结论：目前的结果不支持Eglit等人的应用。D–KEFS彩色单词干扰测试的嵌入式性能效度度量用于颅脑外伤患者的临床评估。
