Translation and cross-cultural adaptation into Brazilian Portuguese of the 35 navigation metrics developed by the Academy of Oncology Nurse & Patient Navigators (AONN+).

objectiveTo perform the translation and cross-cultural adaptation into Brazilian Portuguese of the 35 navigation metrics developed by the Academy of Oncology Nurse & Patient Navigators (AONN+).

methodsThis study employed a methodological approach for cross-cultural adaptation. Following authorization from the authors of the original version of the 35 metrics for evaluating navigation programs, the instrument was translated in accordance with established guidelines. A committee of ten experts was formed to review and reach consensus on the translation. The snowball sampling technique was used to recruit 35 judges, including nurse navigator and oncology nurses, with the aim of assessing the applicability of the metrics to the Brazilian context. The data were collected in the first semester of 2025.

resultsThe expert committee evaluated whether the metrics achieved semantic, idiomatic, experiential, and conceptual equivalence. Three rounds of evaluation were required to reach a 90% agreement rate. In the subsequent pretest, Brazilian oncology nurses and nurse navigators individually assessed each metric for cultural comprehensibility and applicability. The instrument's mean content validity index was 0.97.

conclusionThe 35 metrics were adapted and refined in accordance with the proportions of agreement and content validity index, which reached values consistent with those recommended for adequacy. Therefore, the translation enables the use of standardized navigation metrics to measure program outcomes in Brazil.
