Psychosomatic syndromes in fibromyalgia.

OBJECTIVES

The aim of this study was to compare the prevalence of psychosomatic symptoms in patients with fibromyalgia (FM) or rheumatoid arthritis (RA).

METHODS

Seventy-six consecutive women with FM and 80 with RA without concomitant FM were assessed using the Diagnostic Criteria for Psychosomatic Research (DCPR) interview to evaluate the presence of psychosomatic syndromes. Beck Depression Inventory - II (BDI-II) and Form Y of the State-Trait Anxiety Inventory (STAI-Y) were administered in order to assess the symptoms of anxiety and depression.

RESULTS

Significantly higher levels of anxiety and depression were found in the FM patients (p<0.001), and each FM patient (as against 79% of the RA patients) presented at least one DCPR syndrome. Comparisons of psychological distress between the FM patients with and without each of the psychosomatic syndromes revealed high levels of anxiety and depression in the patients with the psychosomatic condition.

CONCLUSIONS

The findings of this study highlight the greater presence of psychological distress and psychosomatic syndromes in patients with FM than in RA patients. The FM patients with psychosomatic symptoms also showed high levels of psychological distress. A better understanding of the psychosomatic manifestations of FM syndrome could allow clinicians to structure tailored interventions that take more account of the emotional distress associated with the physical complaints.
