    Fibromyalgia and rheumatoid arthritis: Personality and psychopathology differences from the Minnesota Multiphasic Personality Inventory-2
    (Edições Universitárias Lusófonas, 2019) Gonzalez, Bárbara Isabel Dinis; Novo, Rosa Ferreira; Peres, Rodrigo; Baptista, Telmo Ventura Mourinho; HEI-LAB (FCT) - Digital Laboratories for Environments and Human Interactions
    The fibromyalgia syndrome (FM) is a chronic widespread pain condition whose etiology remains unknown. Within a psychosocial approach to FM, personality may play a role as predisposing and/or maintaining factor. A meta-analytic study has identified a distinct Minnesota Multiphasic Personality Inventory-2 (MMPI-2) clinical profile between FM female patients and healthy controls, but the differences between FM and other chronic pain conditions with clear etiology are not established. This cross-sectional study compares the clinical MMPI-2 profile in FM and rheumatoid arthritis (RA) patients, identifies typical groups of each pathology, and further characterizes these groups in the broad MMPI-2 personality and psychopathology dimensions. The MMPI-2 scales were assessed in a sample of 70 women (FM: n = 38, Mage = 46.03, SDage = 8.48; RA: n = 32, Mage = 45.31, SDage = 8.68). The FM group had clinically significant elevations on five clinical scales (Hypochondriasis, Depression, Hysteria, Psychasthenia and Schizophrenia), while RA group had none. A K-Means cluster analysis allowed the identification of a typical profile of each pathology, and subsequent MANCOVAs identified important features of FM patients on several MMPI-2 dimensions. We conclude there is specificity in the personality and psychopathology characteristics of FM patients

    O MMPI-2 na diferenciação da fibromialgia face à artrite reumatóide
    (Associação Iberoamericana de Diagnóstico e Avaliação Psicológica (AIDAP-AIDEP), 2018) Gonzalez, Bárbara Isabel Dinis; Novo, Rosa Ferreira; Peres, Rodrigo; Baptista, Telmo Ventura Mourinho; HEI-LAB (FCT) - Digital Laboratories for Environments and Human Interactions
    Este estudo visa explorar características psicológicas e psicopatológicas associadas à fibromialgia (FM), uma patologia dolorosa de etiologia desconhecida. Para tal, pretende comparar pacientes com FM e pacientes com artrite reumatóide (AR), uma patologia dolorosa de etiologia conhecida, e identificar grupos típicos (GTs) de cada patologia. 70 participantes (FM: n = 38; Midade = 46.03, DPidade = 8.48; AR: n = 32, Midade = 45.31, DPidade = 8.68) foram avaliadas com o MMPI-2. Procedeu-se a uma análise de clusters (K-médias) para identificação de GTs e análises multivariadas intergrupos. A análise de clusters da amostra global, com base na pontuação em oito escalas clínicas, identificou dois clusters: um de menor dimensão (n = 29), caracterizado por médias significativamente inferiores em sete escalas e sem elevações clinicamente significativas (T ≥ 65), integrando 24 pacientes com AR, e outro de maior dimensão (n = 41), caracterizado por elevações clinicamente significativas em cinco escalas, integrando 33 pacientes com FM. Considerados estes clusters como representativos das características psicológicas nucleares de cada uma das patologias, as análises multivariadas mostraram que o FMGT apresenta valores significativamente superiores ao ARGT em várias escalas de psicopatologia da personalidade, suplementares e de conteúdo. Esses resultados serão discutidos reconhecendo-se o papel da personalidade na etiologia e manutenção da FM.

    Personality and psychopathology heterogeneity in MMPI-2 and health-related features in fibromyalgia patients
    (Edições Universitárias Lusófonas, 2021) Gonzalez, Bárbara Isabel Dinis; Novo, Rosa Ferreira; Peres, Rodrigo; HEI-LAB (FCT) - Digital Laboratories for Environments and Human Interactions
    Psychological aspects 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 important 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 dimension. 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.
