To perform a cross-cultural adaptation of the Brazilian Dysphonia Screening Tool (DST-Br) for European Portuguese (EP). The cross-cultural adaptation of the DST-Br for EP was carried out in four stages: translation, back-translation, expert committee review, and pre-testing. The pre-testing involved 30 dysphonic individuals (24 women and 6 men) aged between 18 and 87 years old. An additional statement was required in the EP version of the instrument. Disagreement in the back-translation of the title was resolved through an expert committee review. One item presented discrepancies in the translation and back-translation, with the final version determined through an expert committee review. One item and the answer key reached a consensus in all stages. During pre-testing, all items received 100% "yes" or "no" responses, and none were marked as "not applicable". The cross-cultural adaptation of DST-Br for use in EP was successfully carried out. The European Portuguese version of the instrument was named the Instrumento de Rastreio para a Disfonia em português europeu (IRD-PT) / Dysphonia Screening Tool in European Portuguese.
