title: [Translation into Portuguese, cross-national adaptation and validation of the Female Sexual Function Index].
abstract: OBJECTIVE
  to translate from English into Portuguese, adapt culturally and validate the Female Sexual Function Index (FSFI).
  
  
  METHODS
  knowing the objectives of this research, two Brazilian translators have prepared a version each from the FSFI into Portuguese. Both versions have then been retro-translated into English by two English translators. After harmonizing the differences, they have been pre-tested in a pilot study. The final versions from the FSFI and from another questionnaire, the Short-Form Health Survey, which had already been translated and published in Portuguese, have then been simultaneously administered to one hundred patients, to test the FSFI psychometric proprieties concerning reliability (internal consistency and testing-retesting) and construct validity. Retesting was done after four weeks from the first interview.
  
  
  RESULTS
  the process of cultural adaptation has not altered the Portuguese version of the FSFI, as compared to the original. The FSFI standardized Cronbach alpha was 0.96, and the evaluation by domains has varied from 0.31 to 0.97. As a measure of test-retest confidentiality, it was applied the intra-class coefficient, which has been considered strong and identical (1.0). Pearson's correlation coefficient between the FSFI and the Short-Form Health Survey was positive, but weak in most of the interrelated domains, varying from 0.017 to 0.036.
  
  
  CONCLUSIONS
  the FSFI English version has been translated into Portuguese and culturally adapted, being reliable to evaluate the sexual response of Brazilian women.
