abstract: OBJECTIVE
  To translate and validate the Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST 2.0) into Brazilian Portuguese.
  
  
  METHODS
  Certified translators translated and back-translated Quest. Content validity (CVI) was determined by 5 experts and, after the final version of B-Quest, a pre-test was applied to users of manual wheelchairs, walkers and crutches. The psychometric properties were tested to assure the validity of items and the reliability and stability of the scale.
  
  
  RESULTS
  Data were obtained from 121 users of the above-mentioned devices. Our study showed a CVI of 91.66% and a satisfactory factor analysis referent to the two-dimensional structure of the instrument that ensured the representativeness of the items. The Cron-bach's alpha of the items device, service and total score of B-Quest were 0.862, 0.717 and 0.826, respectively. Test-retest stability conducted after a time interval of 2 months was analyzed using Spearman's correlation test, which showed high correlation (ρ >0.6) for most items.
  
  
  CONCLUSIONS
  The study suggests that the B-Quest is a reliable, representative, and valid instrument to measure the satisfaction of users of assistive technology in Brazil.
