SEGURA, María Virginia. Characterization of WISC-III Test Results Applied to 50 Children with Learning Disorders in Asuncion, Paraguay. Pediatr. (Asunción) [online]. 2012, vol.39, n.2, pp.89-96. ISSN 1683-9803.

We report the quantitative results of a comparative cross-sectional and descriptive study of problems in identifying the results of the Wechsler Intelligence Scale for Children, Third Edition (WISC-III) in 50 schoolchildren with learning disorders in Asunción, Paraguay. Our objective was to describe the results obtained for intelligence quotients, factor analyses, the 13 subtests, and the ACID profile (which summarizes the equivalent scores for arithmetic, coding, information and digit span), and compare them to those obtained by independent investigators in a similar study done in the United States.  Our study was carried out during 2010 using the results on the WISC-III test from 37 male and 13 female children aged 6 to 11 years who were assessed and diagnosed as having learning disabilities at the Instituto de Neuropsicología del Aprendizaje y del Lenguaje (INPAL). On the WISC-III test, children with learning disorders showed a verbal intelligence quotient slightly lower than their performance intelligence quotient and a verbal comprehension index lower than their perceptual organization index, as well as lower scores on the freedom from distractibility and processing speed indexes compared to other indexes. The subtests with the highest median scores were picture completion and block design, while the lowest were in picture arrangement and information, with full ACID profiles found in 6% of children and partial ACID profile in 8.1%.
