Estudo das qualidades psicométricas do Teste de Atenção BQ

Abstract

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.
