There have been numerous methods developed for the detection of valid profiles on the Minnesota Multiphasic Personality Inventory (MMPI)-2. The current study examined a method of combining seven different validity scales of the MMPI-2 into a common weighted method in assessing malingering in chronic pain patients. The weighted method was able to correctly classify 100% of nonlitigants, using a cutoff score of > or =5. The findings of this study suggest that chronic pain patients in litigation produce a different profile on the MMPI-2 validity scales than do nonlitigants. In a group of knowledgeable actors (malingerers), 86% was correctly classified. The overall finding showed 100% specificity and 86% sensitivity. The findings support the need for multiple validity scales to be examined in determining a valid profile. The weighted validity scales method was robust enough to account for "emotional distress" and still identify invalid MMPI-2 performance.
已经开发出了多种用于检测明尼苏达多相人格问卷（MMPI）-2有效剖面图的方法。当前研究考察了一种将MMPI-2的七个不同效度量表组合成一种通用加权方法的方式，以评估慢性疼痛患者中的伪装情况。该加权方法使用≥5的临界分数能够正确分类100%的非诉讼者。本研究结果表明，处于诉讼中的慢性疼痛患者在MMPI-2效度量表上产生的剖面图与非诉讼者不同。在一组知情的演员（伪装者）中，86%被正确分类。总体结果显示特异性为100%，敏感性为86%。这些结果支持在确定有效剖面图时需要检查多个效度量表。加权效度量表方法足够稳健，能够解释“情绪困扰”，并且仍然能够识别无效的MMPI-2表现。
