Abstract
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.
