[Mental disorders in patients with fibromyalgia syndrome: screening in centres of different medical specialties]. / Psychische Störungen beim Fibromyalgiesyndrom: Screening in Einrichtungen verschiedener Fachrichtungen.

ABSTRACT

BACKGROUND: Systematic reviews have reported a wide range of prevalence rates for depressive, anxiety and posttraumatic stress disorders (PTSD) in patients with fibromyalgia syndrome (FMS) which have been partially explained by setting differences. No data are currently available on the prevalence of potential mental disorders depending on the medical specialty in Germany. MATERIAL AND METHODS: All consecutive FMS patients of 8 study centres (3 rheumatology/orthopaedic surgery, 3 psychosomatic/pain medicine, 2 physical/integrative medicine) were assessed from February 1 to July 31, 2012 with standardised questionnaires. Patients with FMS diagnosed by a study physician were included. Non-German speaking and mentally retarded patients were excluded. The German version of the Patient Health Questionnaire 4 was used to screen for potential depressive and anxiety disorders. Severe life events were assessed by the trauma list of the Munich Composite International Diagnostic Interview and symptom criteria of PTSD of the Diagnostic and Statistical Manual of Mental Disorders IV (DSM-IV) using the Posttraumatic Diagnostic Scale. RESULTS: Of 538 patients, 396 patients (93.9 % women, mean age 52.3 years, mean duration since chronic widespread pain 12.8 years, mean duration since FMS diagnosis 4.5 years) were analysed. In all, 65.7 % of patients met the criteria of a potential depressive disorder, 67.9 % of a potential anxiety disorder and 45.5 % of a potential PTSD. Potential depressive disorders were more frequent in the psychosomatic/pain medicine setting than in the rheumatology setting. CONCLUSION: Potential mental disorders were frequent in FMS patients regardless of the medical specialty. All FMS patients of all types of clinical settings should be screened for mental disorders.
