This study examined the validity of the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF; Tellegen & Ben-Porath, 2011) Uncommon Virtues (L-r) and Adjustment Validity (K-r) scales in detecting underreporting. The study aimed to increment the previous literature in this field using a New Zealand population. We used a combined sample of 784 university students, with 173 participants completing the MMPI-2-RF with instruction to underreport in the context of applying for a job, and 611 completing the test under standard instructions. Results indicated that individuals who completed the MMPI-2-RF with underreporting instructions exhibited significantly lower scores on the majority of the MMPI-2-RF substantive scales, and significantly higher scores on the L-r and K-r validity scales. Additionally, L-r and K-r added incremental predictive utility over one another when differentiating the standard instruction and underreporting groups. Classification accuracy analyses provided additional evidence for the utility of the L-r and K-r scales by supporting their respective cut scores listed in the MMPI-2-RF manual (Ben-Porath & Tellegen, 2011). The findings of this study provide further evidence for the utility of the L-r and K-r scales in detecting underreporting extension to both a preemployment evaluation context and a novel population.
本研究旨在检验明尼苏达多相人格测验-2 修订版（MMPI-2-RF；Tellegen 和 Ben-Porath，2011 年）的非凡美德（L-r）和调整效度（K-r）量表在检测掩饰性回答方面的有效性。该研究旨在利用新西兰人群的数据，对该领域的先前文献进行补充。我们使用了一个由 784 名大学生组成的混合样本，其中 173 名参与者在申请工作的背景下完成了 MMPI-2-RF，并按照标准指示完成了 611 次测试。结果表明，按照指示进行掩饰性回答的参与者在 MMPI-2-RF 的大多数实质性量表上的得分显著降低，而在 L-r 和 K-r 效度量表上的得分显著升高。此外，L-r 和 K-r 在区分标准指令和掩饰性回答组方面具有额外的预测效用。分类准确性分析通过支持 MMPI-2-RF 手册中列出的各自临界分数，为 L-r 和 K-r 量表的有效性提供了额外的证据（Ben-Porath 和 Tellegen，2011 年）。本研究的结果为 L-r 和 K-r 量表在检测掩饰性回答方面的有效性提供了进一步的证据，这一发现既扩展到了就业前评估情境，也扩展到了新的人群。
