BRENLLA, María Elena. WISC-IV SCORING AND CHC-BASED INTERPRETATIVE APPROACHES. Cienc. Psicol. [online]. 2013, vol.7, n.2, pp.183-197. ISSN 1688-4221.

Abstract: The validity of WISC-IV current four-factor scoring structure and the Cattel-Horn-Carroll (CHC) theory-based models of the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) we investigated by the application of confirmatory factor analysis of scores from the argentine WISC-IV standardized sample (n = 1437). Results reveal that the WISC-IV measures the same constructs across age, the resulting interpretation could be applied to children with various age levels. Both the four-factor structure and the alternative CHC-based model were supported. Variance explained was similar across models. The WISC-IV measures crystallized ability, visual processing, fluid reasoning, working memory and processing speed. In particular, either separating fluid reasoning and visual processing, or combining them as the Perceptual Reasoning Index provides meaningful explanation.
