Tradução para o português e adaptação cultural do questionário de avaliação cognitiva denominado Literacy Independent Cognitive Assessment

Abstract

Objectives: Individuals with congenital isolated growth hormone deficiency (IGHD), in Brazil Northeastern, have normal lifespan with a prolonged healthspan. Our hypothesis is that a reduction in cognitive decline during aging accompanies their increase in healthspan. Our aim was to translate the Literacy Independent Cognitive Assessment (LICA) into Portuguese and adapt it to the local culture to assess their cognitive function. Methods: In the first stage, a psychologist and a psychiatrist translated the instrument from English, which was revised by an English teacher. In the second, the synthesis of this translation and the cultural adaptation was carried out by the 16 authors, including a nutritionist who suggested common Portuguese food terms, resulting in a second consensus version with some words and images changed. The third step involved an evaluation round with two judges (independent psychologists). The fourth stage was the back translation, which demonstrated 100% of agreement with the previous version. In the fifth stage, a pilot was carried out to verify the understanding of the questionnaire. In the sixth stage, an endocrinologist, and a psychiatrist approved the final Portuguese version, administered to 15 elderly IGHD subjects and 15 local controls. Results: LICA was used 59 times, 5 in the pilot study, 24 in the variability studies and 30 in the experimental step. Inter- and intra-observer variability was 99 and 96%, respectively. The Cronbach's alpha was 0.76, indicating good instrument reliability Conclusions: This version of the LICA is a valuable tool for cognitive assessment in Portuguese-speaking elderly people.
