title: Development of the Brazilian brief version of the Diabetes Quality of Life Measure (DQOL-Brazil-8).
abstract: OBJECTIVE
  To provide for Brazil, through the selection of items of the Brazilian version of the Diabetes Quality of Life Measure (DQOL-Brazil), a concise instrument.
  
  
  METHODS
  This is a cross-sectional study in which the DQOL-Brazil was administered to 150 type 1 diabetic patients and 146 type 2 diabetic patients. The items of the instrument were selected according to the analysis of the principal components and Spearman's correlations with treatment satisfaction, glycated hemoglobin level, and Nottingham Health Profile.
  
  
  RESULTS
  From a total of 44 items, only 8 were selected to compose the summary instrument (DQOL-Brazil-8). The DQOL-Brazil-8 presented Spearman's correlation of 0.873 with the DQOL-Brazil and a Cronbach's alpha coefficient of 0.702.
  
  
  CONCLUSIONS
  The Brazilian health professionals now have a brief tool for a fast application that preserves the best features of the full DQOL-Brazil.
