Localization and validation of the "Growing Up With Hearing Loss" tool for Brazilian Portuguese.

Only 7 children and adolescents and 7 young adults took part, and the researchers ran no statistical comparisons between groups, so the differences between the four agreement rates are descriptions rather than tested effects. Participants were recruited in person and through social media and answered remotely, which favours people with internet access and comfort using digital technology. The videos kept their original recordings with Portuguese subtitles only, which is likely why children and adolescents reported difficulty reading them; no dubbing or sign language version was tested. Back-translation was not performed, so equivalence with the original English relied on expert review rather than on translating the text back and comparing it. Cronbach's alpha in the children and adolescents group was negative (-1.15), so the internal consistency of that questionnaire could not be established. The material's usefulness and effect on rehabilitation outcomes were never measured; participants only judged its clarity and content.

Funded by CAPES (Financing Code 001) and FAPESP (2024/10070-0, 2024/05187-6). The tool's copyright holder, the Ida Institute, gave formal authorisation for the localisation, which was carried out under an academic cooperation agreement between the Ida Institute and FOB-USP, so the developer of the material was a partner in the project.

Do not read the high agreement rates as evidence that the tool improves hearing rehabilitation. The 42 participants rated the translated material's clarity and usefulness, no patient outcomes were measured, and the four groups were never compared statistically, so this is a judgement about content, not about whether the tool works.
