Desenvolvimento e Propriedades Psicométricas do Teste Informatizado de Avaliação das Funções Executivas

Abstract

Executive functions (EF) are skills linked to behavioral and cognitive self-control and are related to various outcomes throughout life. The use of computerized tests to evaluate EFs can facilitate the accuracy of records, standardization and data analysis. This study aimed to develop a computerized instrument for the EF assessment of children aged 4 to 10 years, and to seek psychometric evidence. Five steps were carried out: 1. Theoretical and methodological definition; 2. Construction of the items; 3. Pilot study; 4. Analysis of experts; and 5. Psychometric studies of validity and reliability. The computerized tasks proved to be suitable for the target audience according to the expert’s evaluation. The results between the different tasks of working memory, inhibition and cognitive flexibility showed significant correlations and most test-retest measures showed stability in the measurement. Therefore, the results indicate the feasibility of using the instrument in the Brazilian context.
