Structure of the Wechsler Intelligence Scale for Children – Fourth Edition in a Group of Children with ADHD

Factor Structure of the Wechsler Intelligence Scale for Children: Fourth Edition in Children with ADHD.

OBJECTIVE Recent evidence suggests that the factor structure of the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) is better explained by a five-factor model rather than the four-factor model in the standardization sample. The current study examined the WISC-IV's factor structure in a sample of children with ADHD. METHOD Participants included 314 children and adolescents wh...

Structure of the Wechsler Intelligence Scale for Children – Fourth Edition in a Group of Children with ADHD

OBJECTIVE This study used confirmatory factor analysis to examine the factor structure for the 10 core WISC-IV subtests in a group of children (N = 812) with ADHD. METHOD The study examined oblique four- and five-factor models, higher order models with one general secondary factor and four and five primary factors, and a bifactor model with a general factor and four specific factors. RESULT...

Factor Structure of the Wechsler Intelligence Scale for Children - Fourth Edition among Students with Attention Deficit

Orthogonal higher order structure of the Wechsler Intelligence Scale For Children--fourth edition.

According to J. B. Carroll's (1993) 3-stratum theory, performance on any subtest reflects a mixture of both 2nd-order and 1st-order factors. To disentangle these influences, variance explained by the general factor should be extracted first. The 1st-order factors are then residualized, leaving them orthogonal to the general factor and each other. When these methods were applied to the WISC-IV s...
