Abstract

Objective

The present study investigated demographic differences in performance validity test (PVT) failure in a Veteran sample.

Method

Data were extracted from clinical neuropsychological evaluations. Only veterans who identified as men, as either European American/White (EA) or African American/Black (AA) were included (n = 1261). We investigated whether performance on two frequently used PVTs, the Test of Memory Malingering (TOMM), and the Medical Symptom Validity Test (MSVT), differed by age, education, and race using separate logistic regressions.

Results

Veterans with younger age, less education, and Veterans Affairs (VA) service-connected disability were significantly more likely to fail both PVTs. Race was not a significant predictor of MSVT failure, but AA patients were significantly more likely than EA patients to fail the TOMM. For all significant demographic predictors in the models, effects were small. In a subsample of patients who were given both PVTs (n = 461), the effects of race on performance remained.

Conclusions

Performance on the TOMM and MSVT differed by age and level of education. Performance on the TOMM differed between EA and AA patients, whereas performance on the MSVT did not. These results suggest that demographic factors may play a small but measurable role in performance on specific PVTs.

绩效有效性测试失败的人口统计学差异

摘要

客观的

本研究调查了退伍军人样本中绩效有效性测试（PVT）失败的人口统计学差异。

方法

数据是从临床神经心理学评估中提取的。仅包含男性退伍军人，即欧洲裔美国人/白人 (EA) 或非裔美国人/黑人 (AA) ( n  = 1261)。我们使用单独的逻辑回归研究了两种常用 PVT（记忆欺骗测试 (TOMM) 和医学症状有效性测试 (MSVT)）的表现是否因年龄、教育程度和种族而异。

结果

年龄较小、受教育程度较低以及退伍军人事务部 (VA) 服务相关残疾的退伍军人更有可能未能通过两项 PVT。种族并不是 MSVT 失败的重要预测因素，但 AA 患者比 EA 患者更有可能出现 TOMM 失败。对于模型中所有重要的人口预测因素，影响都很小。在接受两种 PVT 的患者子样本中（n  = 461），种族对表现的影响仍然存在。

结论

TOMM 和 MSVT 的表现因年龄和教育水平而异。EA 和 AA 患者在 TOMM 上的表现不同，而在 MSVT 上的表现则没有差异。这些结果表明，人口因素可能在特定 PVT 的表现中发挥虽小但可衡量的作用。
