SANTANA, Yuri E. G. et al. Validity evidence for the Neuropsychological Test for the Assessment of Visuospatial Binding: a working memory test. Aval. psicol. [online]. 2022, vol.21, n.2, pp. 227-235. ISSN 1677-0471.  http://dx.doi.org/10.15689/ap.2022.2102.20888.10.

The Neuropsychological Test for the Assessment of Visuospatial Binding (TNABV) was developed to measure the Working Memory binding for object-location features. This study aimed to provide validity evidence related to the content and internal structure of the TNABV. To investigate the evidence based on internal structure, the sample was composed of 1173 people. Participants were between 18 and 95 years of age. In order to investigate the content-related validity evidence, a judgment was performed through the analysis of seven experts. The data analysis was carried out through exploratory factor analysis, the Internal Consistency Content Validity Index (CVI). The result suggested a one-dimensional model with an explained variation of 41.78% and Cronbach's alpha of .82. The total CVI showed an agreement of .98. The findings indicated that the psychometric properties evaluated in the TNABV are adequate.
