Abstract

A study was designed to find out whether MMPI-2 validity scales and indexes differentiate between true fibromyalgia sufferers, patients with chronic organic pain and normal people, as well as whether they are correctly classified. 105 subjects participated in the study, 27 diagnosed with fibromyalgia and 44 with chronic organic pain and 34 were healthy people, who answered the MMPI-2 following standard instructions. The results showed that fibromyalgia patients scored higher than the control group in the F, Fb, F-K, Fp, Ds, and FBS scales and indexes and that patients with chronic organic pain scored higher in the Ds and FBS scales than the control group. The case study revealed that the F, Fb, F-K, Fp, Ds, and FBS scales and indexes over-diagnose malingering in patients with fibromyalgia, both in comparison with the clinical population and with the normative group. Likewise, patients with chronic organic pain were overdiagnosed as malingerers by all the scales and indexes in comparison with the normative population and by the Fp and FBS scales in comparison with the clinical population. In addition, it was found that at least one of the scales for measuring defensiveness –L, Wsd and Mp– classified 79.5% of the truly ill patients as faking good. The implications for clinical and forensic practice are discussed, as well as for the definition of decision criteria and the (re)classification as true negatives of genuine cases classified as malingerers by the malingering measuring scales and indexes.

MMPI-2效度量表和指标对慢性疼痛和纤维肌痛患者的分类是否正确?
一项研究旨在了解MMPI-2效度量表和指标是否能区分真正的纤维肌痛患者、慢性器质性疼痛患者和正常人,以及它们的分类是否正确。105名受试者参与了这项研究,其中27人被诊断为纤维肌痛,44人被诊断为慢性有机疼痛,34人是健康人,他们按照标准指示回答了MMPI-2。结果显示,纤维肌痛患者的F、Fb、F- k、Fp、Ds和FBS量表及指标得分均高于对照组,慢性器质性疼痛患者的Ds和FBS量表得分均高于对照组。本病例研究显示,F、Fb、F- k、Fp、Ds和FBS量表和指标,无论是与临床人群还是与正常组相比,都对纤维肌痛患者的装病有过度诊断。同样,慢性器质性疼痛患者在各项量表和指标上与正常人群比较,在Fp和FBS量表上与临床人群比较,均被误诊为装病者。此外,研究还发现,至少有一项用于测量防御的量表——l、Wsd和Mp——将79.5%的真正患病的患者归为假装好。本文讨论了对临床和法医实践的影响,以及对决策标准的定义和(重新)分类为真阴性的真实病例,这些病例被诈欺测量量表和指数分类为诈欺者。
