Fenollar-Cortés, Javier; Watkins, Marley W. – International Journal of School & Educational Psychology, 2019
The construct validity of the Spanish Version of the Wechsler Intelligence Scale for Children Fifth Edition (WISC-V[superscript Spain]) was investigated via confirmatory factor analysis. For all 15 subtests, the higher-order model preferred by Wechsler (2015b) contained five group factors but lacked discriminant validity. A bifactor model with…

Canivez, Gary L.; Watkins, Marley W.; McGill, Ryan J. – British Journal of Educational Psychology, 2019
Background: There is inadequate information regarding the factor structure of the Wechsler Intelligence Scale for Children -- Fifth UK Edition (WISC-V[superscript UK]; Wechsler, 2016a, Wechsler Intelligence Scale for Children-Fifth UK Edition, Harcourt Assessment, London, UK) to guide interpretation. Aims and methods: The WISC-V[superscript UK]…

The reliability and factorial validity of the Wechsler Intelligence Scale for Children--Fifth Edition: Canadian (WISC-V[superscript CDN]) was investigated. The higher-order model preferred by Wechsler (2014b) contained five group factors but lacked discriminant validity. An alternative bifactor model with four group factors and one general factor,…

Background: Irish educational psychologists frequently use the Wechsler Intelligence Scale for Children-Fourth UK Edition (WISC-IV[superscript UK]; Wechsler, 2004, Wechsler Intelligence Scale for Children-Fourth UK Edition, London, UK, Harcourt Assessment) in clinical assessments of children with learning difficulties. Unfortunately, reliability…

Confirmatory factor analysis was used to determine the factor structure of the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) scores of 297 children referred to a children's hospital in the Southwestern United States. Results support previous findings that indicate the WISC-IV is best represented by a direct hierarchical…

Pendergast, Laura L.; Watkins, Marley W.; Canivez, Gary L. – Educational Psychology, 2014
Homework is a requirement for most school-age children, but research on the benefits and drawbacks of homework is limited by lack of psychometrically sound measurement of homework performance. This study examined the structural and convergent validity of scores from the newly developed Homework Performance Questionnaire -- Teacher Scale (HPQ-T).…

The Native American population is severely underrepresented in empirical test validity research despite being overrepresented in special education programs and at increased risk for psychoeducational evaluation. The structural validity of the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) was investigated with a sample of 176,…
