Validation of the cancer survivors' unmet needs questionnaire - CaSUN for brazilian culture
Abstract
Objective: to carry out the cross-cultural adaptation and validation of the Cancer Survivors' Unmet Needs questionnaire for Brazilian culture, with a focus on women with breast cancer. Method: methodological study carried out between May 2024 and February 2025, in two stages: 1) translation and cross-cultural adaptation, and 2) validation of psychometric properties. Seven people participated in the first stage, and 214 cancer survivors participated in the second. Participants in the second stage completed the sociodemographic and clinical questionnaires, as well as the translated and adapted Cancer Survivors' Unmet Needs questionnaire. For data analysis, Cronbach's alpha and Kappa coefficients were calculated, and a factor model of multivariate analysis was fitted. Results: The factor analysis revealed that some factors migrated, but without the need to alter the original structure. Cronbach's alpha was 0.88, indicating acceptable internal consistency, and the reliability using the Kappa test was 0.86, indicating almost perfect agreement. Conclusion: The Brazilian version of the Cancer Survivors' Unmet Needs questionnaire adhered to the original structure, demonstrating adequate internal consistency and reliability, and revealed that the questionnaire is valid for measuring the unmet needs of breast cancer survivors.
