title: Validation of the EuroQol quality of life questionnaire on stroke victims.
abstract: OBJECTIVE
  To validate a quality of life scale, EuroQoL, on stroke patients.
  
  
  METHODS
  67 patients were scored simultaneously for EuroQoL-5 Dimensions (EQ-5D), NIH Stroke Scale (NIHSS) and modified Barthel Index (mBI). Pearson test was used to correlate each scale. Additionally, 31 patients were examined by two independent evaluators on the same day through application of EQ-5D. Kappa statistics were used to evaluate interobserver agreement.
  
  
  RESULTS
  EQ-5D showed good correlation with both stroke severity (NIHSS, r= -0.404, P<0.001) and degree of impairment on activities of daily living (mBI, r=0.512, P<0.001). We noticed a good interobserver agreement (k>0.60) in all dimensions evaluated (P<0.01).
  
  
  CONCLUSIONS
  We demonstrated that EQ-5D is reproducible and valid on evaluation of quality of life in patients post stroke in Brazil.
