title: [Translation, cultural adaptation, validity and reliability of the shoulder rating questionnaire for use in Brazil].
abstract: OBJECTIVE
  To translate and culturally adapt the Shoulder Rating Questionnaire (SRQ) to the Brazilian Portuguese language, and to determine its validity, reliability and sensitivity to change in patients with functional impairment of the shoulder.
  
  
  METHODS
  After translation and back-translation of the original version by four independent translators, the instrument was reviewed by a committee of experts and subsequently applied to eight patients with shoulder injury (target audience) to produce the Portuguese version. Then, this version was applied to 102 patients selected from four reference centers for functional treatment of the shoulder, who had a variety of clinical diagnoses, educational levels, socioeconomic, and cultural backgrounds. The evaluation was performed twice with an interval of four weeks between each application.
  
  
  RESULTS
  The Brazilian version of SRQ was equivalent in terms of semantics and showed good levels of reliability (Cronbach's Alpha=0.89 and ICC=0.83). The reproducibility was high (Spearman Correlation Coefficient=0.82) and validity of the items that ranged from 0.54 to 0.99 was considered excellent. The Cohen's d and T test for repeated measures showed that the instrument is able to monitor and track improvements in shoulder function.
  
  
  CONCLUSIONS
  Psychometric criteria were found, which justify the applicability of the Brazilian version of SRQ in individuals with shoulder functional impairments.
