This study investigates the capacity of the MMPI to discriminate among groups of patients with different types of pain. When multivariate analysis of variance is used, the standard set of MMPI scales discriminates between acute pain and chronic pain but not between chronic pain of two different etiologies (surgical-iatrogenic vs. unknown). The three scales that discriminate acute from chronic pain patients are those in the "neurotic triad," Hs, D, and Hy. The possibility that the unknown pain etiology group could be broken down into psychogenic pain and undetected somatogenic pathology subgroups was explored using cluster analysis. This procedure did not yield any group of patients who could be identified as having chronic pain of psychogenic origin. These results suggest that the MMPI is not a reliable tool for the differential diagnosis of chronic pain. It appears, however, that patterns of findings are partly contingent on population characteristics. Researchers should be cautious about generalizing to populations other than those from which samples are drawn.
本研究调查了明尼苏达多相人格调查表（MMPI）区分不同类型疼痛患者群体的能力。当使用多变量方差分析时，MMPI量表的标准集能够区分急性疼痛和慢性疼痛，但无法区分两种不同病因（手术 - 医源性与不明病因）的慢性疼痛。区分急性疼痛患者和慢性疼痛患者的三个量表是“神经症三联征”中的量表，即疑病量表（Hs）、抑郁量表（D）和癔病量表（Hy）。使用聚类分析探讨了不明疼痛病因组是否可以细分为心因性疼痛和未检测到的躯体性病理亚组的可能性。该程序并未产生任何可被确定为患有心因性慢性疼痛的患者群体。这些结果表明，MMPI并非慢性疼痛鉴别诊断的可靠工具。然而，研究结果模式似乎部分取决于人群特征。研究人员在将研究结果推广到抽样人群以外的其他人群时应谨慎。
