Background It is popularly believed thatpatients with fibromyalgia display a neurotic personality. Our hypothesis was that patients with fibromyalgia had higher scores of neurocitism and introversion than in other rheumatic diseases.
Objectives To compare the personality between patients with fibromyalgia and patients with other rheumatic diseases. The hypothesis of apersonality type of FM patients has already been mentioned in literature, as evidenced by two literature reviews of Auquier et al. (1)and Fieta et al.(2)which show conflicting results. We compared the five major personality traits in patients with fibromyalgia andin patients followed for other rheumatic diseases, including Rheumatoid Arthritis (RA), Gougerot Sjögren syndrome (SS), and Spondyloarthritis (SpA).
Methods The Big Five Inventory (BFI) questionnaire (3) was used to assess and compare the five major personality dimensions of patients with fibromyalgia, RA, SpA or SS. Patients were included between June 2010 and January 2011. They had to be women, without any concomitant chronic disease or malignancies, with disease duration less than 10 years. Validated diseases criteria were used to select patients.
Results Sixty-fourpatients filled the questionnaire. These patients were followed for fibromyalgia (n = 15), RA (n = 16), SpA (n = 18), or SS (n = 15). The patients with fibromyalgia group had a higher score of agreeableness than other patients groups (p= 0,006). There was no significant difference in the neuroticismscore (p = 0.451) between patients with fibromyalgia and the other studied groups.
Conclusions Neurocitism do not seem to be higher in fibromyalgia group than in other rheumatic diseases.
