The items bank of the Fatigue domain is part of an American system developed for evaluation of results reported by patients, called Patient-Reported-Outcomes Measurement Information System (PROMIS). This study aimed to translate and cross-culturally adapt this item bank for the Brazilian population, as a promising new tool for evaluating health-related quality of life. The items in this bank were translated using rigorous translation and back-translation protocols. The translated version was pre-tested in twenty Brazilians with a brief cognitive and retrospective interview in order to test the items’ conceptual, cultural, and semantic equivalences. In the translation and back-translation process, only three of the 82 items had to be reworded due to the culturally inadequate content. In the pretest, only four items needed to be reworded, but without conceptual and semantic alterations. The results showed that the translated version of this item bank is conceptually, culturally, and semantically equivalent to the original version.
