Background: Nutritional screening is defined by American Society for Parenteral and Enteral Nutrition (ASPEN) as a process to identify individuals at risk of malnutrition. Malnutrition is a prevalent condition in cirrhotic patients, and it results in important prognostic implications. Most of the commonly used instruments fail in considering the particularities of cirrhotic patients. The Royal Free Hospital-Nutritional Prioritizing Tool (RFH-NPT) is a nutritional screening tool developed and validated to identify malnutrition risk in patients with liver disease.
Objective: The study's aim was to conduct the transcultural adaptation (translation and adaptation) of RFH-NPT tool to Portuguese (Brazil).
Methods: The process of cultural translation and adaptation followed the Beaton et al. methodology. The process involved the steps of initial translation, synthesis translation, back translation pretest of the final version with 40 nutritionists and a specialists committee. The internal consistency was calculated with the Cronbach coefficient and the content validation was verified with the content validation index.
Results: Forty clinical nutritionists with experience in treatment of adult patients participated in the step of cross-cultural adaptation. The alpha Cronbach coefficient was 0.84, which means high reliability. In the specialists analyzes all the tool's questions achieved a validation content index higher than 0.8, showing high agreement.
Conclusion: The NFH-NPT tool was translated and adapted to Portuguese (Brazil) and showed high reliability.
