SOTO, César Merino. Dimensionality of Bender Gestalt Visual Motor Test Modified: a confirmatory factor analysis. Aval. psicol. [online]. 2013, vol.12, n.3, pp.341-350. ISSN 1677-0471.

The aim of this study is to examine the structural characteristics of a new brief version of the Bender Gestalt Test of Bender, modified for children between 4 and 8 years (BGT-M). The participants were 1369 children from various urban areas of Lima, Peru. The BGT-M was group or individually administered, and dimensionality was verified using the methodology of confirmatory factor analysis, and the internal consistency with factorial methodology with the classical test theory methodologies. The results justify the unidimensionality of the total score, but the variance retained and construct reliability varies by age level; also, the configurationally invariance of the items is satisfactory in all age groups. Internal consistency is satisfactory. We discuss the interpretation of the variability of results between ages, and the possible extension of the TGB-M in children over 8 years.

Keywords : qualitative scoring system; Bender gestalt test; factor analysis; validity; reliability.
