BESSA, Jonatas R. et al. Evidence of validity of the Attentional Performance Test (APT). Psicol. teor. prat. [online]. 2021, vol.23, n.2, pp. 01-21. ISSN 1516-3687.

This study aims to present evidence of validity of the Attentional Performance Test (APT). The search for evidence based on content, internal structure and reliability was carried out. The content's evidence was run with the expert judgement (n = 07; k = 0.84) and semantic analysis (n = 12, k = 0.77). Their results suggested an adequate agreement with the content of the assessment of sustained attention (S.A), verbal commands and the images of the instrument. An analysis of the factorial structure (n = 1086) resulted on 2 main factors, 4 dimensions and 12 measures (RMSR = 0.08). An analysis of internal consistency (n = 1086) of the APT showed adequate values (α > 70). This study indicated that the APT presents evidence for content, construct and reliability. The present results contribute to APT evidences to confirm it as an adequate psychometric instrument to assess attention.
