GOMES, Cristiano Mauro Assis  and  BORGES, Oto Neri. Psychometric proprieties of visual-spatial ability tests kit. PsicoUSF [online]. 2009, vol.14, n.1, pp. 19-34. ISSN 1413-8271.

This article analyses the psychometrical properties of a test kit developed to measure visual-spatial ability in terms of its factorial structure, unidimensionality, convergent validity and divergent validity. A sample of 558 students that were either attending High School or had just concluded it participated of this research. The Visualization Test (Vz), Flexibility of Closure Test (CF), Visual Memory Test (MV), Figural Fluency Test (FF), Ideational Fluency Test 1 (FI1) and Ideational Fluency Test 2 (FI2) were used. The data analysis used the exploratory factorial analysis, the confirmatory factorial analysis and the fit to the Rasch model procedures. The model fit indexes are in accordance with the cutoff values suggested by the literature. The tests showed a two-level factorial structure, although it can be taken as an unidimensional structure. The tests converge to measure the visual-spatial ability and diverge to measure the fluency ability which was used in this study as contrast ability.
