Abstract

Objective: The aim of this investigation was to provide information about the utility of the newly revised and renormed Minnesota Multiphasic Personality Inventory-3 (MMPI-3) over-reporting scales in a forensic disability sample. Method: Participants consisted of 550 non-head injury disability-related referrals (i.e. 95.6% for worker’s compensation) and were primarily diagnosed with an adjustment disorder, depressive disorder, or posttraumatic stress disorder. Criterion measures included performance validity indicators and non-MMPI symptom validity indicators. Results: Correlation analyses showed that validity scale F was most strongly associated with non-MMPI symptom validity indicators, whereas F, Fs, FBS, and RBS were comparable to each other in their associations with performance validity indicators. Group mean comparisons between Pass versus Fail PVT groups showed that RBS consistently yielded the largest effect sizes. Using established structured criteria for Malingered Neurocognitive Dysfunction (MND), additional group mean comparisons showed that RBS, followed by Fs, F, and FBS, performed well in differentiating genuine responders from MND examinees. Classification accuracy estimates indicated that the MMPI-3 over-reporting scales performed well in the prediction of Probable/Definite MND and, as expected, to a lesser degree of Possible MND. Conclusions: Practical applications, study limitations, and directions for future research are discussed. The overall findings from this study provide empirical support for the utility of the MMPI-3 over-reporting scales in detecting negative response bias in forensic disability evaluations.

摘要

目标：本调查的目的是提供有关新修订和重新规范的明尼苏达多相人格量表 3 (MMPI-3) 过度报告量表在法医残疾样本中的效用的信息。方法：参与者包括 550 名非头部受伤残疾相关转介（即 95.6% 的工人赔偿），主要被诊断患有适应障碍、抑郁症或创伤后应激障碍。标准措施包括绩效效度指标和非 MMPI 症状效度指标。结果：相关性分析表明，效度量表 F 与非 MMPI 症状效度指标的相关性最强，而 F、Fs、FBS 和 RBS 在与绩效效度指标的关联方面具有可比性。通过与失败 PVT 组之间的组均值比较表明，RBS 始终产生最大的影响大小。使用已建立的神经认知功能障碍 (MND) 结构化标准，额外的组均值比较表明 RBS，其次是 Fs、F 和 FBS，在区分真正的反应者和 MND 受试者方面表现良好。分类准确度估计表明，MMPI-3 过度报告量表在预测可能/明确 MND方面表现良好，并且正如预期的那样，对可能 MND的预测程度较低. 结论：讨论了实际应用、研究局限性和未来研究方向。本研究的总体结果为 MMPI-3 过度报告量表在检测法医残疾评估中的负面反应偏差方面的效用提供了实证支持。
