The objective of this study was to identify the frequency of anxiety and depression symptoms by verifying the association between anxiety traits, current depression and anxiety symptoms in fibromyalgia patients. Interviews were performed with 60 subjects diagnosed with fibromyalgia at the Rheumatology Outpatient Clinic at Universidade Federal de Sergipe between August 2007 and March 2008, in which two questionnaires were administered: the Hospital Anxiety and Depression Scale (HADS) and the State-Trait Anxiety Inventory (STAI). The frequency of anxiety and depression symptoms was, respectively, 50% and 86% for individuals with fibromyalgia, and the mean trait-anxiety score was 59.38. An association was observed between trait and state anxiety. Anxiety and depression were frequent symptoms among patients with fibromyalgia. However, anxiety appeared as a secondary symptom to depression, appearing in a more severe form, and, therefore, this comorbidity should be more valued and studied.
