Personality and psychopathology features may play an important role as predisposing factors for fibromyalgia (FM). However, psychological heterogeneity of FM patients has been suggested. Based on two personality psychopathology clusters, we intend to explore psychological heterogeneity in FM patients, specifically, to identify if personality features had other psychological and psychopathological correlates. Secondarily, we also want to identify if personality features have association with health‐related correlates. The participants were female FM patients (n = 56) between 30 and 60 years old. The instruments were: Minnesota Multiphasic Personality Inventory (MMPI‐2) content and supplementary scales, Fibromyalgia Impact Questionnaire (FIQ), and Numerical Rating Scale (NRS‐11). Multivariate analyses of variance (MANOVAs) identified that Cluster 2 (n = 24), characterized by a combination of negative affectivity and social inhibition, presented a more disturbed profile, with several features of symptomatic behavior, general maladjustment, and important clinical problem areas. The associations of personality variables with FM impact and self‐reported pain are null, with the exception of Disconstraint scale. In conclusion, FM patients may be very different at the psychological level, concerning personality and psychopathological features that may compromise their treatment. Personality and health‐related dimensions do not seem to be associated.

MMPI-2的人格和心理病理异质性以及纤维肌痛患者的健康相关特征

人格和心理病理特征可能作为纤维肌痛（FM）的诱发因素发挥重要作用。然而，已经提出了FM患者的心理异质性。基于两个人格心理病理学聚类，我们打算探讨FM患者的心理异质性，特别是确定人格特征是否还有其他心理和心理病理学相关性。其次，我们还想确定人格特征是否与健康相关者相关。参与者是女性FM患者（n = 56）30至60岁之间。这些工具包括：明尼苏达州多相人格量表（MMPI-2）内容和补充量表，纤维肌痛影响问卷（FIQ）和数字量表（NRS-11）。多变量方差分析（MANOVA）确定，以负面情感和社会抑制相结合为特征的聚类2（n =  24）表现出更易受干扰的特征，具有症状行为，一般适应不良和重要的临床问题区域的几个特征。人格变量与FM影响和自我报告的疼痛之间的关联为零，但Disconstraint除外规模。总之，调频患者在心理水平上可能有很大差异，在人格和心理病理特征方面可能会影响他们的治疗。与人格和健康相关的维度似乎没有关联。
