Our study compared the impact of administering Symptom Validity Tests (SVTs) and Performance Validity Tests (PVTs) in in-person versus remote formats and assessed different approaches to combining validity test results. Using the MMPI-2-RF, IOP-29, IOP-M, and FIT, we assessed 164 adults, with half instructed to feign mild traumatic brain injury (mTBI) and half to respond honestly. Within each subgroup, half completed the tests in person, and the other half completed them online via videoconferencing. Results from 2 ×2 analyses of variance showed no significant effects of administration format on SVT and PVT scores. When comparing feigners to controls, the MMPI-2-RF RBS exhibited the largest effect size (d = 3.05) among all examined measures. Accordingly, we conducted a series of two-step hierarchical logistic regression models by entering the MMPI-2-RF RBS first, followed by each other SVT and PVT individually. We found that the IOP-29 and IOP-M were the only measures that yielded incremental validity beyond the effects of the MMPI-2-RF RBS in predicting group membership. Taken together, these findings suggest that administering these SVTs and PVTs in-person or remotely yields similar results, and the combination of MMPI and IOP indexes might be particularly effective in identifying feigned mTBI.
我们的研究比较了以面对面形式和远程形式进行症状效度测试（SVT）和表现效度测试（PVT）的影响，并评估了综合效度测试结果的不同方法。我们使用明尼苏达多项人格测验第二版修订版（MMPI-2-RF）、29项症状自评量表（IOP-29）、Millon临床多轴问卷（IOP-M）和功能独立量表（FIT），对164名成年人进行了评估，其中一半人被指示假装轻度创伤性脑损伤（mTBI），另一半人被要求如实作答。在每个亚组中，一半人亲自完成测试，另一半人通过视频会议在线完成测试。方差分析的结果显示，施测形式对SVT和PVT分数没有显著影响。在比较假装者和对照组时，MMPI-2-RF反向伪装量表（RBS）在所有检测指标中显示出最大的效应量（d = 3.05）。因此，我们进行了一系列两步分层逻辑回归模型，首先纳入MMPI-2-RF RBS，然后分别纳入其他每个SVT和PVT。我们发现，在预测组成员身份方面，IOP-29和IOP-M是唯一在MMPI-2-RF RBS的影响之外产生增量效度的指标。综上所述，这些发现表明，以面对面或远程方式进行这些SVT和PVT会产生相似的结果，并且MMPI和IOP指标的组合在识别假装的mTBI方面可能特别有效。
