Introduction: Although many studies highlighted the importance of the psychological component associated with Fibromyalgia (FM), few studies investigated the clinical utility of the Diagnostic Criteria for Psychosomatic Research (DCPR) in FM. The aim is to investigate the prevalence of psychosomatic syndromes, as assessed with the DCPR, in a group of FM patients and to evaluate their impact on the psychosocial functioning. Methods: Two groups of 101 patients with FM or Rheumatoid Arthritis (RA) were assessed using the DCPR, the Hospital Anxiety and Depression Scale (HADS) and the SF-36 that evaluates the physical (SF-36_PC) and mental (SF-36_MC) component of health related quality of life. Results: The results indicated a significantly higher prevalence of psychosomatic syndromes in the somatization (persistent somatization: 64.4% vs 14.9%; conversion symptoms: 48.5% vs 6.9%; anniversary reaction: 45.5% vs 17.8%), irritability (type A behavior: 57.4% vs 34.7%; irritable mood: 40.6% vs 24.8%), and demoralization (51.5% vs 17.8%) clusters of the DCPR in FM compared to RA patients. The multiple linear regression indicated that, even controlling for depressive (p< .001) and anxiety symptoms (p= .027), abnormal illness behavior (p= .006), somatization (p= .021) and demoralization (p= .025) were statistically significant contributing factors in explaining the negative impact of FM on the SF-36_MC. Conclusion: The data confirmed a very high prevalence of psychosomatic syndromes in FM patients. Furthermore, psychosomatic syndromes showed a predictive validity in detecting a low health-related quality of life in FM patients, highlighting the clinical utility of the DCPR in detecting patients’ psychosocial dysfunction. The clinical utility of the Structured Clinical Interview for DSM-5 Personality Disorders (SCID-5-PD) and of the Structured Interview of Personality Organization (STIPO) will also be briefly discussed in order to provide an overview on the existing diagnostic instruments.

Abstract
Introduction: Although many studies highlighted the importance of the psychological component associated with Fibromyalgia (FM), few studies investigated the clinical utility of the Diagnostic Criteria for Psychosomatic Research (DCPR) in FM. The aim is to investigate the prevalence of psychosomatic syndromes, as assessed with the DCPR, in a group of FM patients and to evaluate their impact on the psychosocial functioning. Methods: Two groups of 101 patients with FM or Rheumatoid Arthritis (RA) were assessed using the DCPR, the Hospital Anxiety and Depression Scale (HADS) and the SF-36 that evaluates the physical (SF-36_PC) and mental (SF-36_MC) component of health related quality of life.
