The validity of intelligence tests using the Cattell-Horn-Carroll model of intelligence with a preschool population

Morgan, Kimberly E. January 2008 (has links)
Individual differences in human intellectual abilities and the measurement of those differences have been of great interest to the field of school psychology. As such, different theoretical perspectives and corresponding test batteries have evolved over the years as a way to explain and measure these abilities. A growing interest in the field of school psychology has been to use more than one intelligence test in a "cross-battery" assessment in hopes of measuring a wider range (or a more in-depth but selective range) of cognitive abilities. Additionally, interest in assessing intelligence began to focus on preschool-aged children because of initiatives to intervene early with at-risk children. The purpose of this study was to examine the Stanford-Binet Intelligence Scales, Fifth Edition (SB-V) and Kaufman Assessment Battery for Children, Second Edition (KABC-II) in relation to the Cattell-Horn-Carroll (CHC) theory of intelligence using a population of 200 preschool children. Confirmatory factor analyses (CFAs) were conducted with these two tests individually as well as in conjunction with one another. Different variations of the CHC model were examined to determine which provided the best representation of the underlying CHC constructs measured by these tests. Results of the CFAs with the SBV revealed that it was best interpreted from a two-stratum model, although results with the KABC-II indicated that the three-stratum CHC model was the best overall design. Finally, results from the joint CFA did not provide support for a cross-battery assessment with these two particular tests.3 / Department of Educational Psychology

A joint-confirmatory factor analysis using the Woodcock-Johnson III tests of cognitive ability and the Stanford-Binet Intelligence Scales, fifth edition, with high achieving children / Joint confirmatory factor analysis using the Woodcock-Johnson III tests of cognitive ability and the Stanford-Binet Intelligence Scales, fifth edition, with high achieving children

A considerable about of research has concentrated on studying the performance of high achieving children on measures of intellectual functioning. Findings have indicated high achieving children display differences in performance patterns as well as in the cognitive constructs measured when compared to their average peers. The conceptualization of intelligence has evolved over time and contemporary theories of intelligence have described cognitive ability as consisting of multiple constructs which are often interrelated. Currently. one of the most comprehensive and empirically supported theories of intelligence is the Cattell-Horn-Carroll (CHC) theory (Cattell, 1941; Horn, 1968: Carroll, 1993). The multidimensional and hierarchical CHC theory has served as the foundation for the development and recent revisions of cognitive ability measures such as the Woodcock-Johnson Tests of Cognitive Ability– Third Edition (WJ-III COG; McGrew & Woodcock 2001) and the Stanford-Binet Intelligence Scales – Fifth Edition (SBS: Raid, 2003b). The purpose of this study was to explore the construct validity of the WJ-III COG and SB5 with a sample of high achieving children. Individual confirmatory factor analyses were conducted using the WJ-III COG and SB5. Additionally. a joint confirmatory factor analysis was conducted using both the WJ-III COG and SB5. The results indicated an alternative six-factor WJ-IlI COG and four-factor SB5 models provided the best fit to the data of a high achieving sample, supporting previous research suggesting high achieving children display differences in cognitive constructs when compared with their average counterparts. The joint-confirmatory factor analysis indicated the best measures for the CHC factors measured by both the WJ-III COG and SB5 to help guide cross-battery assessments with high functioning children. Clinical applications of the findings are discussed. / Department of Educational Psychology

Significant evidence from the legislation, medical/clinical, or professional practice perspective all points to the advantages and necessity of conducting comprehensive assessment of cognitive abilities, especially in young children, to identify cognitive deficits, arrive at an accurate diagnosis, and establish bases for developing interventions and recommending services. Cross-battery assessment approach provides school psychologists a useful tool to strengthen their preferred cognitive battery by adopting and comparing subtests from other batteries to build up a comprehensive and theoretically sound evaluation of an individual’s cognitive profile to increase the validity of test interpretation. Using joint confirmatory factor analysis, this study explored the combined underlying construct validity of the Woodcock-Johnson Tests of Cognitive Abilities, Third Edition (WJ-III COG) and the Stanford-Binet Intelligence Scales, Fifth Edition (SB5) with an independent sample of preschool children. Seven models were examined and the results showed that relatively, the underlying construct of the two tests was best represented by a threestratum alternative CHC model in which the Gf factor and subtests had been removed. This indicates that not all the CHC constructs shared by both tests can be reliably identified among young children. Constructs of the CHC theory may be represented differently on preschool cognitive batteries due to developmental influences. Although WJ-III COG and SB5 tests as a whole did not demonstrate good results for purposes of cross-battery assessment, certain subtests (e.g., subtests representing crystallized intelligence) from each battery offer interpretative value for individual broad ability factors, providing school psychologists an in-depth understanding of a preschooler’s crystallized knowledge. Exploratory factor analyses were conducted with subtests from WJ-III COG and SB5 representing the four shared broad factors (Gc, Gf, Gv, and Gsm). Results revealed that a 4-factor solution is a better model fit to the data. Future research includes recruiting young children with disabilities or special needs to explore best representative underlying construct of combined WJ-III COG and SB5, allowing for cross-battery assessment. / Access to thesis permanently restricted to Ball State community only / Department of Educational Psychology
