The fibromyalgia syndrome (FM) is a chronic widespread pain condition whose etiology remains unknown and no treatment has satisfactory levels of success. A metaanalysis has identified a distinct Minnesota Multiphasic Personality Inventory-2 (MMPI-2) clinical profile between FM female patients and healthy controls, and differences between FM and other chronic pain condition with clear etiology have also been found. However, heterogeneity in this population has been suggested in several studies. We aim to assess clinical aspects in FM patients, based on personality psychopathology characteristics, in order to explore heterogeneity and the existence of core common aspects. In this cross-sectional study, a relatively homogeneous sample of 56 female FM patients (Mage = 45.95, SDage = 9.39) was assessed through MMPI-2. A K-Means cluster analysis identified two clusters, one (n = 24) with clinically significant levels in Negative Emotionality and Introversion scales. Subsequent MANOVAs identified important features of this cluster on several MMPI-2 dimensions. Moreover, several dimensions are clinically elevated in both clusters. In conclusion, the combination of psychopathological negative emotionality, interpersonal isolation, and low hedonic capacity, in a group of patients, has implications for the daily living and treatment of FM patients, and several core aspects of FM need to be addressed.
This study aimed to characterize a group of women diagnosed with fibromyalgia, evaluating the relationship between personality and psychopathology, health status (disability, physical health, mental health, and pain), and potentially traumatic life events (PTLE) before the onset of the syndrome. The disability caused by fibromyalgia, physical and mental health status, pain, PTLE in childhood and in the course of life, and personality were assessed in a sample of 50 women with fibromyalgia, age 25-70 years (M = 46.96; SD = 10.96). A multiple correspondence analysis with all the variables identified two types of profiles and a K-Means cluster analysis confirmed two groups of patients: cluster 1 (n = 36), with better health and less psychopathological problems, named "Better adjustment" and cluster 2 (n = 14), with less health and more personality problems, named "Disorder and disability." Pertaining to personality only, a K-Means cluster analysis replicated the three classic personality profiles (normal, neurotic, and psychopathological) identified in chronic pain patients; and the normal profile was the more prevalent (n = 22). The results enhance the importance of recognizing the heterogeneity of fibromyalgia population and the great closeness between personality and physical health, with the PTLE having a less important role than expected.
This study aimed to evaluate the relation of disability and physical and mental health status with potentially traumatic life events (PTLE) before the onset of fibromyalgia in women diagnosed with this syndrome. We also investigated causal attribution of fibromyalgia to a triggering event, physical or psychological in nature, and its relation with the health measures and the adverse life events. The impact of fibromyalgia, physical and mental health status, pain, PTLE in childhood and not in childhood, and causal attribution were assessed in a sample of 50 women with fibromyalgia, aged 25-70 (M = 46.96; SD = 10.96). There were no statistically significant relations between the health measures (disability, physical and mental health, and pain) and the PTLE. The predominant attribution was to a physical event. There were no significant differences neither in the health measures across causal attribution status (Pillai's Trace = 0.193; F(8,90) = 1.200; p = .308; η2 par = .096) nor in the PTLE not in childhood (F(2,47) = 1.063; p = .354; η2 par = .043). There were significant differences across causal attribution status in the PTLE in childhood (F(2,47) = 3.590; p = .035; η2 par = .133), specifically between the group that made a psychological attribution and the group that made no attribution (C.I. 95%) 0.1805; 14.0468; (p = .043), with the former having a higher score of PTLE in childhood. The results raise questions about the importance of psychological aspects in the appraisal of the adverse events and its possible relation to the psychological functioning in women with fibromyalgia.
