RESUMENObjetivo: Traducir y adaptar culturalmente para Brasil la escala Pain Assessment in Advanced Dementia (PAINAD). Método: El proceso de adaptación cultural del instrumento utilizó la metodología de un referencial teórico, realizada en cinco etapas: traducción para el portugués -brasileño, versión consensual de las traducciones, retro-traducción para el idioma original, revisión por un comité de expertos en el área del instrumento y prueba piloto de equivalencia. En la última etapa, el instrumento fue evaluado y aplicado por 27 profesionales de la salud. Resultados: La Escala de Evaluación del Dolor en Demencia Avanzada fue adaptada culturalmente para Brasil y mostró equivalencia semántica con la original, así como claridad, aplicabilidad y fácil comprensión de los elementos del instrumento. Conclusión: Este proceso garantizó las propiedades psicométricas tales como confiabilidad y la validez de contenido de esa escala.

Through an integrative literature review involving the CINAHL, Cochrane, Embase, LILACS, PsycINFO, PubMed databases, tools available in the literature for assessing pain in individuals with severe dementia were identified along with versions validated for use in Brazil. We found 1501 relevant articles which, after selection of abstracts and full reading, yielded a final sample of 33 articles. The analysis enabled the identification of 12 instruments: ABBEY PAIN SCALE; ADD; CNPI; CPAT; DOLOPLUS-2; MOBID and MOBID-2; MPS; NOPPAIN; PACSLAC; PADE; PAINAD and PAINE. Despite the wide variety of tools for assessing pain in individuals with severe dementia worldwide, it was observed that only four are available in Portuguese, of which two are culturally adapted for Brazilian Portuguese (NOPPAIN and PACSLAC) and two validated for Portuguese of Portugal (DOLOPLUS and PAINAD), pointing to the need for further validation of instruments for use in Brazil.
