Background: The Fibromyalgia syndrome (FMS) is suggested to be a manifestation of depression or affective spectrum disorder. We measured the cognitive style of patients with FMS to assess personality styles in 44 patients with Fibromyalgia syndrome (FMS) by comparing them with 43 patients with major depressive disorder (MDD) and 41 healthy controls (HC).

Methods: Personality styles were measured by the Sociotropy and Autonomy Scale (SAS) and the Dysfunctional Attitude Scale (DAS). The Structured Clinical interview for DSM Axis I was applied to Axis I disorders, while the Beck Depression Inventory was used to measure depression severity.

Results: Patients with FMS in general have a sociotropic personality style similar to patients with major depressive disorder, and different from healthy controls, but FMS patients without a lifetime history of major depressive disorder had a cognitive personality style different from patients with major depressive disorder and similar to healthy controls.

Conclusions: These findings suggest that a depressotypic personality style is related to depressive disorder, but not to FMS. Trial registration: NCT00184106
