title: RELIABILITY OF THE FATIGUE SEVERITY SCALE IN CIRRHOTIC AND CORRELATION WITH DEPRESSION AND QUALITY OF LIFE: preliminary assessment.
abstract: BACKGROUND
  Fatigue is a common complaint in patients with liver disease and may be considered a disabling symptom, affecting their quality of life and mental health. The Brazilian version of the Fatigue Severity Scale showed sensitivity to assess fatigue in some populations, but has not been tested in cirrhotic individuals.
  
  
  OBJECTIVE
  The aim of this study was to evaluate the reliability of the Fatigue Severity Scale and association with depression and quality of life in patients with liver cirrhosis.
  
  
  METHODS
  A prospective cohort study where the same interviewer applied to 25 patients Fatigue Severity Scale questionnaires, Brazilian version of the Beck Depression Inventory II (BDI- II) and Brazilian version of the Short Form Health Survey II (SF-36 v.II). Evaluating the reliability of the Fatigue Severity Scale through internal consistency and reproducibility was conducted.
  
  
  RESULTS
  Statistical analysis showed strong internal consistency (Cronbach's alpha = 0.917) and intraobserver reproducibility test, there was no significant difference between both moments (P=0.828). Fatigue Severity Scale was significantly associated with BDI- II (r=0.478; P=0.016) and quality of life in areas PF (r=-0.484; P=0.014), BP (r=-0.402; P=0.046) and GH (r=-0.406; P=0.044) and SF (r=-0.520; P=0.008).
  
  
  CONCLUSIONS
  The Fatigue Severity Scale showed satisfactory reliability in evaluation of fatigue in cirrhotic and can be used as a tool for this purpose. Fatigue is related to depression and quality of life in the physical aspects domains, pain, general health and social aspects.
