Abstract

Objective: This study aimed to explore the correlates of zero, one, and multiple performance validity test (PVT) failures on cognitive test performance in patients with various degrees of severity of traumatic brain injury.

Method: 306 participants completed the Trail Making Test as part of a neuropsychological evaluation within 1-36 months post-injury. They were assigned to zero, one, or ≥ two fail groups on the basis of at least two independent PVTs. Group differences in Trail Making Test performance were analyzed with analysis of variance, with post hoc contrasts with the Bonferroni correction for multiple comparisons. Groups were also compared on various background characteristics.

Results: Participants who passed all PVTs had statistically significantly better performance on both parts of the Trail Making Test as compared to those who failed either one or multiple PVTs, with the latter two groups not differing statistically significantly from each other. PVT failure was relatively more common in participants who were female, had an uncomplicated mild TBI, were involved in financial compensation-seeking, and were seen at a longer time point since injury.

Conclusion: Failure of even only one PVT is associated with lower neuropsychological test performance in patients with traumatic brain injury, especially when empirically validated criteria are used that are stratified by injury severity. Such failure does not always reflect malingering but must be interpreted and addressed in the context of patient background characteristics.

在创伤性脑损伤后，单个效能效度测试的失败很重要。

目的：探讨不同严重程度颅脑损伤患者的零效度测试、一效度测试和多重效度测试不及格对认知测试成绩的影响。方法：306名参与者在受伤后1-36个月内完成了Trail Making Test作为神经心理学评估的一部分。根据至少两个独立的pvt，他们被分配到0、1或≥2个失败组。用方差分析分析各组在Trail Making Test表现上的差异，用Bonferroni校正进行多重比较的事后对比。各组之间还进行了各种背景特征的比较。结果：通过所有pvt的参与者与不通过一个或多个pvt的参与者相比，在Trail Making Test的两个部分上都有统计学上显著更好的表现，后两组在统计学上没有显著差异。PVT衰竭在女性、无并发症的轻度脑外伤、有经济赔偿寻求、在受伤后较长的时间点出现的参与者中相对更常见。结论：在创伤性脑损伤患者中，即使只有一个PVT失败也与较低的神经心理测试成绩有关，特别是当根据损伤严重程度分层使用经验验证的标准时。这种失败并不总是反映装病，但必须在患者背景特征的背景下解释和解决。

期刊介绍： The Journal of the International Neuropsychological Society is the official journal of the International Neuropsychological Society, an organization of over 4,500 international members from a variety of disciplines. The Journal of the International Neuropsychological Society welcomes original, creative, high quality research papers covering all areas of neuropsychology. The focus of articles may be primarily experimental, applied, or clinical. Contributions will broadly reflect the interest of all areas of neuropsychology, including but not limited to: development of cognitive processes, brain-behavior relationships, adult and pediatric neuropsychology, neurobehavioral syndromes (such as aphasia or apraxia), and the interfaces of neuropsychology with related areas such as behavioral neurology, neuropsychiatry, genetics, and cognitive neuroscience. Papers that utilize behavioral, neuroimaging, and electrophysiological measures are appropriate. To assure maximum flexibility and to promote diverse mechanisms of scholarly communication, the following formats are available in addition to a Regular Research Article: Brief Communication is a shorter research article; Rapid Communication is intended for "fast breaking" new work that does not yet justify a full length article and is placed on a fast review track; Case Report is a theoretically important and unique case study; Critical Review and Short Review are thoughtful considerations of topics of importance to neuropsychology and include meta-analyses; Dialogue provides a forum for publishing two distinct positions on controversial issues in a point-counterpoint format; Special Issue and Special Section consist of several articles linked thematically; Letter to the Editor responds to recent articles published in the Journal of the International Neuropsychological Society; and Book Review, which is considered but is no longer solicited.
