Resumo
A Atenção Seletiva permite-nos fazer a seleção entre estímulos relevantes e estímulos
irrelevantes ou distrações. O objetivo do presente estudo consiste na compreensão das
qualidades psicométricas, nomeadamente, a validade convergente, divergente, concorrente e a
fiabilidade do teste bq, uma adaptação informatizada do teste d2, que tem como objetivo avaliar
a atenção seletiva de um indivíduo. A amostra é constituída por 34 participantes, com uma
média de idades de 39,15 anos (DP= 12,2). Foi aplicado um conjunto de provas
neuropsicológicas, nomeadamente, o teste Montreal Cognitive Assessment (MoCA), o teste d2,
o teste bq, o questionário Beck Depression Inventary - II (BDI-II) e o questionário de
usabilidade, de forma a compreender como os indivíduos classificam a experiência com os
testes d2 e bq. Os resultados obtidos no estudo vão ao encontro dos objetivos, quer para as
validades convergente, divergente e concorrente, como a consistência interna do teste bq, com
um α de Cronbach excelente para 4 dos 9 parâmetros avaliados. Assim, verificou-se que o teste
bq é eficaz, sendo necessário em estudos futuros, uma amostra mais heterogénea e a analise de
outras medidas psicométricas como a estabilidade temporal.
Selective Attention allows us to make the selection between relevant stimulus and irrelevant stimulus or distractions. The aim of this study is to understand the psychometric qualities, namely, the convergent, divergent, concurrent validity and the reliability of the bq test, a computerized adaptation of the d2 test, which aims to assess an individual's selective attention. The sample consists in 34 participants, with a mean age of 39.15 years (SD= 12.2). A set of neuropsychological tests was applied, namely the Montreal Cognitive Assessment (MoCA), the d2 test, the bq test, the Beck Depression Inventary - II (BDI-II) questionnaire and the usability questionnaire, so we could understand how they classify the experience with the d2 and bq tests. The results obtained in the study meet the objectives, for both convergent, divergent and concurrent validity. There was also an internal consistency of the bq test, with an excellent Cronbach's α for 4 of the 9 parameters evaluated. Thus, it was verified that the bq test is effective, being necessary in future studies, a more heterogeneous sample and to analyze other psychometric measures such as temporal stability.
