Abstract
Education interferes with the performance in most cognitive tests, including executive function assessment. Objective: To investigate the effects of education on the performance of healthy elderly on the Brazilian version of the Executive Interview (EXIT25). Methods: The EXIT25 was administered to a sample of 83 healthy elderly. The subjects were also submitted to the Mini-Mental State Examination (MMSE), a delayed recall test, clock drawing and category fluency (animals/min) tests in order to rule out cognitive impairment. The Geriatric Depression Scale (GDS) was employed to exclude clinically-relevant depressive symptoms. The total sample was divided into three groups according to educational level: G1 (1-4 years), G2 (5-8 years) and G3 (>8 years). Results: The mean values for age, educational level, MMSE and EXIT25 scores of all subjects were 72.2, 7.5, 27.6 and 6.9, respectively. The scores on the EXIT25 for each group were: G1=8.3, G2=5.9 and G3=5.8. There was a statistical difference between the performance of G1 and the other two groups on the EXIT25. Conclusions: The Brazilian version of the EXIT25 proved straightforward to administer. The performance of this sample of healthy elderly on the test was significantly influenced by educational level.
Key words:

Resumo
O nível educacional interfere no desempenho da maioria dos testes cognitivos incluindo os de função executiva. Objetivo: Investigar os efeitos da educação no desempenho de idosos saudáveis na versão brasileira do teste de funções executivas (EXIT25). Métodos: O EXIT25 foi administrado a uma amostra de 83 idosos saudáveis. Os indivíduos foram também submetidos ao Mini-Exame de Estado Mental (MEEM), a um teste de evocação, ao desenho do relógio e ao teste de fluência de categorias (animais/min) com a função de excluir prejuízos cognitivos. A Escala de Depressão Geriátrica foi aplicada para excluir sintomas de depressão clinicamente relevante. O total da amostra foi dividido em três grupos de acordo com o nível educacional: G1 (1-4 anos), G2 (5-8 anos) e G3 (>8 anos). Resultados: As médias de idade, nível educacional, MEEM e EXIT25 de todos os indivíduos foram respectivamente de 72,2; 7,5; 27,6 e 6,9. Os valores do EXIT25 para cada grupo foram: G1=8,3; G2=5,9 e G3=5,8. Houve diferença estatística entre o desempenho de G1 e os outros dois grupos no EXIT25. Conclusões: A versão brasileira do EXIT25 provou ser de fácil administração. O desempenho da amostra de idosos examinada foi significativamente influenciada pelo nível educacional.
