A criterion-groups validation was used to determine the classification accuracy of the Seashore Rhythm Test (SRT) and Speech Sounds Perception Test (SSPT) in detecting malingered neurocognitive dysfunction (MND) in traumatic brain injury (TBI). TBI patients were classified into the following groups: (1) Mild TBI Not-MND (n = 24); (2) Mild TBI MND (n = 27); and (3) Moderate/Severe TBI Not-MND (n = 23). A sample of 90 general clinical patients was utilized for comparison. Results showed that both SRT correct and SSPT errors differentiated malingerers from non-malingerers in the Mild TBI sample. At 96% specificity, sensitivities were 37% for SRT correct and 59% for SSPT errors. Joint classification accuracy showed that the best accuracy was achieved when using a cut-off associated with a 4% false positive error rate in the Mild TBI sample. Specificity was considerably lower in the Moderate/Severe TBI and General Clinical groups. The clinical application of these findings is discussed.
采用效标组验证来确定海沙滩节奏测试（SRT）和语音感知测试（SSPT）在检测创伤性脑损伤（TBI）中伪装的神经认知功能障碍（MND）的分类准确性。TBI 患者被分为以下几组：（1）轻度 TBI 非 MND（n = 24）；（2）轻度 TBI MND（n = 27）；和（3）中重度 TBI 非 MND（n = 23）。利用 90 名一般临床患者的样本进行比较。结果表明，在轻度 TBI 样本中，SRT 正确和 SSPT 错误都能区分伪装者和非伪装者。特异性为 96%时，SRT 正确的灵敏度为 37%，SSPT 错误的灵敏度为 59%。联合分类准确性表明，在轻度 TBI 样本中，当使用与假阳性错误率为 4%相关的截止值时，可获得最佳准确性。在中重度 TBI 和一般临床组中，特异性明显较低。讨论了这些发现的临床应用。
