MERINO SOTO, César. A nonparametric item analysis of the Bender gestalt test modified for primary students. Liberabit [online]. 2009, vol.15, n.2, pp. 83-94. ISSN 1729-4827.

This research designs a psychometric study of a new scoring system of the Bender Gestalt test modified to children: it is the Qualitative Scoring System (Brannigan & Brunner, 2002), in a sample of 244 first grade children of primary level, in four public schools of Lima. The approach applied is the nonparametric item analysis using the Test graft computer program (Ramsay, 1991). Our findings point to good levels of internal consistency, unidimensionality and good discriminative level of the categories of scoring from the Qualitative Scoring System. There are not demographic differences between gender or age. We discuss our findings within the context of the potential use of the Qualitative Scoring System and of the nonparametric item analysis approach in the psychometric research.
