"Galveston Orientation and Amnesia Test": tradução e validação

Abstract

OBJETIVO: Traduzir e validar o Galveston Orientation and Amnesia Test para uso em nosso meio. MÉTODOS: Esse teste foi traduzido para o português e retro-traduzido para o inglês por diferentes especialistas na língua e por fim, feita a avaliação da equivalência entre o instrumento original e a versão retro-traduzida. Sua aplicação em 73 vítimas de trauma crânio-encefálico contuso e a indicação da gravidade dessa lesão, estabelecida pela Escala de Coma de Glasgow, permitiram verificar as propriedades de medida do instrumento. RESULTADOS: A confiabilidade verificada pelo Alfa de Cronbach resultou em 0,76. Houve indicação de validade convergente e discriminante do instrumento quando os resultados de aplicação do Galveston Orientation and Amnésia Test foram analisados perante a gravidade do trauma crânio-encefálico. CONCLUSÃO: Os resultados observados dão suporte para a aplicação do Galveston Orientation and Amnesia Test em nosso meio como indicador do término da amnésia pós-traumática.

Galveston Orientation Amnesia Test (GOAT)

“…One of the conditions for the alpha calculation is that all involved items are positively correlated, and this hypothesis was satisfied by all questions that compose the instrument. The calculated alpha for the instrument reached 0.76, therefore higher than the one adopted as acceptable (2,19) .…”

“…The translation process followed a smooth course and the comparison between the original and back-translated scales resulted in the indication, by the assessor, of the idiomatic and conceptual equivalence of both versions of the instrument (2,19) .…”

“…Throughout the data collection process, 73 patients were located and followed up in different health-care units for daily assessment. CHI victims from 12 to 60 years of age, with neither a previous diagnosis of cranio-encephalic trauma nor memory alteration, assisted in the study locus after sustaining a trauma, and who were ad-mitted for treatment in the period that ranged from January 3rd to May 3rd 2001, took part in the case study (2,19) .…”

“…Hence, the GCS1 high scores -indicating light trauma -tended to be associated with high scores in the GOAT during the first assessment for the follow-up process of the victims. On the other hand, the GCS1 low score -indicating severe CHIwas related with the GOAT's low scores (2,19) .…”

“…The control group was composed of patients who had moderate and light trauma pointed out by the GCS1 scores (9)(10)(11)(12)(13)(14)(15), and the case group was composed of victims with severe trauma, according to the scores of the same scale (3-8) (2,19) .…”
