The current investigation was designed to examine the impact of underreporting response bias on the Multidimensional Personality Questionnaire (MPQ) and the utility of the Unlikely Virtues scale in detecting such responding. Study participants were randomly assigned to either the underreporting (n = 100) or standard instruction (n = 224) conditions. All participants first completed a series of extratest measures under standard instruction prior to the MPQ administration. The results showed that individuals in the underreporting condition scored significantly higher on MPQ scales that reflect positive emotionality and self-control and lower on scales that indicate negative emotionality compared to those in the standard instruction. Moreover, the psychometric validity of MPQ scale scores against extratest measures was substantially attenuated in the underreporting condition compared to the standard instruction condition. The Unlikely Virtues scale differentiated between the conditions at a large effect size magnitude (Hedges' g = 1.21) and showed promising classification accuracy though lower cut scores than those reported in the MPQ manual performed substantially better with respect to sensitivity. Future research needs to replicate these findings in more naturalistic settings with other research designs. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

多维人格问卷 (MPQ) 不太可能的美德量表在检测漏报中的评价。



目前的调查旨在检查漏报反应偏倚对多维人格问卷 (MPQ) 的影响以及不太可能的美德量表在检测此类反应中的效用。研究参与者被随机分配到漏报 (n = 100) 或标准教学 (n = 224) 条件。所有参与者首先在 MPQ 给药前根据标准说明完成了一系列外测措施。结果表明,与标准教学中的个体相比,处于漏报状态的个体在反映积极情绪和自我控制的 MPQ 量表上的得分明显较高,而在表明消极情绪的量表上的得分较低。此外,与标准教学条件相比,在漏报条件下,MPQ 量表分数相对于外测措施的心理测量效度显着减弱。Unlikely Virtues 量表在大效应量级 (Hedges' g = 1.21) 下区分条件,并显示出有希望的分类准确性,尽管比 MPQ 手册中报告的分数分数低,但在敏感性方面表现要好得多。未来的研究需要在更自然的环境中与其他研究设计一起复制这些发现。(PsycInfo 数据库记录 (c) 2024 APA,保留所有权利)。
