Abstract

Objective: To determine if similar levels of performance on the Overall Test Battery Mean (OTBM) occur at different forced choice test (FCT) p-value score failures. Second, to determine the OTBM levels that are associated with failures at above chance on various performance validity (PVT) tests. Method: OTBMs were computed from archival data obtained from four practices. We calculated each examinee's Estimated Premorbid Global Ability (EPGA) and OTBM. The sample size was 5,103 examinees with 282 (5.5%) of these scoring below chance at p ≤ .20 on at least one FCT. Results: The OTBM associated with a failure at p ≤ .20 was equivalent to the OTBM that was associated with failing 6 or more PVTs at above-chance cutoffs. The mean OTBMs relative to increasingly strict FCT p cutoffs were similar (T scores in the 30s). As expected, there was an inverse relationship between the number of PVTs failed and examinees' OTBMs. Conclusions: The data support the use of p ≤ .20 as the probability level for testing the significance of below chance performance on FCTs. The OTBM can be used to index the influence of invalid performance on outcomes, especially when an examinee scores below chance.

强迫选择测试得分p≤0.20，且≥6项性能效度测试失败，导致类似的Overall test Battery Means。

目的:确定在不同的强迫选择测试(FCT) p值评分失败时，是否会出现类似的总体测试电池平均值(OTBM)表现水平。其次，确定在各种性能有效性(PVT)测试中与高于概率的失败相关的OTBM级别。方法:根据四个实践的档案数据计算otbm。我们计算了每位考生的预估病前整体能力(EPGA)和OTBM。样本量为5103名考生，其中282人(5.5%)在至少一项FCT上得分低于机会，p≤0.20。结果:与p≤0.20失败相关的OTBM与在高于机会截止点失败6个或更多pvt相关的OTBM相当。相对于越来越严格的FCT p截止值，平均otbm相似(T分数在30分左右)。正如预期的那样，pvt不及格的人数与考生的otbm之间呈反比关系。结论:数据支持使用p≤0.20作为检验fct上机会以下表现显著性的概率水平。OTBM可以用来衡量无效表现对结果的影响，特别是当考生得分低于机会时。

期刊介绍： The Clinical Neuropsychologist (TCN) serves as the premier forum for (1) state-of-the-art clinically-relevant scientific research, (2) in-depth professional discussions of matters germane to evidence-based practice, and (3) clinical case studies in neuropsychology. Of particular interest are papers that can make definitive statements about a given topic (thereby having implications for the standards of clinical practice) and those with the potential to expand today’s clinical frontiers. Research on all age groups, and on both clinical and normal populations, is considered.
