The present study examined the factor structure of the Wechsler Intelligence Scale for Children– Fourth Edition, Spanish (WISC–IV Spanish, Wechsler, 2005a) with normative sample participants aged 6–16 years (N = 500) using confirmatory factor analytic techniques not reported in the WISC– IV Spanish Manual (Wechsler, 2005b). For the 10 core subtest configuration, 1 through 4, firstorder factor m...

Irish educational psychologists frequently use the Wechsler Intelligence Scale for Children– Fourth U.K. Edition (WISC–IV) in clinical assessments of children with learning difficulties. Unfortunately, reliability and validity studies of the WISC–IV have not yet been reported. This study examined the construct validity of WISC–IV core subtest scores obtained from evaluations to assess learning ...

The Wechsler Intelligence Scale for Children-Fifth Edition (WISC-V; Wechsler, 2014 ) provides a general intelligence score, representing g, and five index scores, reflecting underlying broad factors. Within person differences between the overall performance across subtests denoted as difference are often used to examine profiles of strengths weaknesses. In this study, validity such was examined...

The structure of the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV; D. Wechsler, 2003a) was analyzed via confirmatory factor analysis among a national sample of 355 students referred for psychoeducational evaluation by 93 school psychologists from 35 states. The structure of the WISC-IV core battery was best represented by four first-order factors as per D. Wechsler (2003b), ...

A meta-analysis of the stability of low IQ (IQ < 80) was performed on IQ tests that have been commonly used--tests that were derived by D. Wechsler (1949, 1955, 1974, 1981, 1991, 1997) and those based on the Binet scales (L. M. Terman, 1960; L. M. Terman & Merrill, 1972). Weighted-mean stability coefficients of .77 and .78 were found for Verbal IQ (V IQ) and Performance IQ (P IQ) on the Wechsle...
