ABSTRACT Objectives: to translate and culturally adapt the Infant Feeding Intentions Scale for pregnant women in Brazil. Methods: methodological study that included stages of translation, synthesis, face and content validation, back translation and semantic assessment. In the face and content and semantic validation stages, we used the Content Validity Index for individual items and for the overall scale for clarity and representativeness. Results: nine (100.0%) experts participated in face and content validation, and the average index obtained was 85.0% for representativeness. In the semantic assessment, performed with 31 (100.0%) pregnant women, the tool was considered clear, obtaining an average index of 91.0%. Conclusions: the Brazilian version of the scale was considered representative and clear. After assessing psychometric properties, the scale is expected to be valid and reliable to assess maternal intention to breastfeed exclusively until the infant’s six months of life in different Brazilian settings.
