Objective: This study investigated the effects of concurrent psychiatric disorders and psychosomatic syndromes on the functional impairment of patients with fibromyalgia. Methods: The study included two hundred patients diagnosed with fibromyalgia and treated at the Karadeniz Technical University Medical Faculty Physical Medicine and Rehabilitation Department. All patients were evaluated using a sociodemographic data form, the Fibromyalgia Impact Questionnaire (FIQ), Symptom Checklist-90 Revised (SCL-90R), Diagnostic Criteria for Psychosomatic Research (DCPR), and the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). Results: Somatic Symptom Disorder (SSD) diagnostic criteria according to DSM-5 were met by 27.5 % of the patients, and illness anxiety disorder (IAD) criteria by 3 %. According to DCPR, 26 % of the participants were diagnosed with persistent somatization, 16 % with disease phobia, 3.5 % with health anxiety, and 17.5 % with thanatophobia. Diagnoses of both SSD and persistent somatization were associated with an increase in SCL-90-R somatization symptom severity and FIQ scores. At the same time, no significant relationship was determined between these diagnoses and anxiety, obsessive-compulsive, or depression symptom severity. Multivariate logistic regression analysis revealed that DCPR persistent somatization and disease phobia affected high FIQ scores independently of SSD, depressive disorder, and demoralization. Conclusions: Defining health anxiety and pathological illness anxiety among the DSM-5 criteria as distinct diagnoses from SSD may increase the functional usefulness of DSM-5 in patients with fibromyalgia.
