Abstract
Objective
To translate, adapt and validate the Frail Non-Disabled Questionnaire (FiND) for the Brazilian context.
Method
The steps recommended by the international literature for health instruments were followed: initial translation, synthesis of translations, back-translation, review by a committee of experts, pre-test, and assessment of the scale’s psychometric properties. All ethical precepts were followed.
Results
The translation and back-translation were performed by two independent and qualified translators. The expert review demonstrated its content validity. In the pre-test, FiND was easy to understand and apply. In the assessment of psychometric properties, the instrument demonstrated good values of reliability and reproducibility. Concurrent criterion validity was verified, finding a positive correlation with statistical significance between the FiND score and Fried’s Fragility Phenotype and good values of sensitivity, specificity, positive and negative predictive values, and accuracy. The convergent construct validity was analyzed, indicating a positive correlation between the FiND score and depressive symptoms, and negative correlations with nutritional and cognitive status, and with the domains of the physical component of quality of life, with statistical significance. Discriminant validity was analyzed by comparing FiND means between the robust, non-frail, and fragile groups, with and without depressive symptoms, with a better and worse perception of quality of life, and with adequate nutritional status, at risk of malnutrition and with a state of malnutrition, which proved to be statistically significant.
Conclusion
FiND has been translated, adapted, and validated for the Brazilian context.
