Peer reviewed Peer reviewed
Direct linkDirect link
Potvin, Deborah C. H.; Keith, Timothy Z.; Caemmerer, Jacqueline M.; Trundt, Katherine M. – Journal of Psychoeducational Assessment, 2015
With an age range from 3 to 13 years, the Kaufman Assessment Battery for Children-Second Edition (KABC-II) offers an appealing option for the assessment of cognitive abilities for children. Although independent research has provided evidence of the construct validity of the KABC-II for school-age children, previous studies have rarely included an…

Weiss, Lawrence G.; Keith, Timothy Z.; Zhu, Jianjun; Chen, Hsinyi – Journal of Psychoeducational Assessment, 2013
The purpose of this study was to determine the constructs measured by the WISC-IV and the consistency of measurement across large normative and clinical samples. Competing higher order four- and five-factor models were analyzed using the WISC-IV normative sample and clinical subjects. The four-factor solution is the model published with the test…

Reynolds, Matthew R.; Keith, Timothy Z.; Fine, Jodene Goldenring; Fisher, Melissa E.; Low, Justin A. – School Psychology Quarterly, 2007
The Kaufman Assessment Battery for Children-Second Edition (KABC-II) is a departure from the original KABC in that it allows for interpretation via two theoretical models of intelligence. This study had two purposes: to determine whether the KABC-II measures the same constructs across ages and to investigate whether those constructs are…

Factor Structure of the K-ABC for Referred School Children.
Peer reviewed Peer reviewed
Keith, Timothy Z. – Psychology in the Schools, 1986
K-ABC (Kaufman Assessment Battery for Children) scores for 585 school-age children referred for psychological evaluation were factor analyzed. While it appears that the K-ABC factor structure is quite consistent for both normal and exceptional children, the meaning and names of factors found are open to interpretation. (Author/ABB)

Witta, E. Lea; Keith, Timothy Z. – 1994
Although the Wechsler Intelligence Scale for Children-Revised (WISC-R) is being rapidly replaced by the third edition of the WISC, questions concerning the construct validity of the WISC-R have not yet been resolved, including the number of factors it measures and whether the same constructs fit across all age levels. This study sought to…

Factor Structure of the McCarthy Scales for Children Experiencing Problems in School.
Peer reviewed Peer reviewed
Keith, Timothy Z.; Bolen, Larry M. – Psychology in the Schools, 1980
The McCarthy Scales of Children's Abilities (MSCA) General Cognitive Index provides a good measure of cognitive ability of exceptional children. The verbal and motor scales also seem valid. Interpretation of remaining scales should be made cautiously as scales may not accurately measure abilities of exceptional children. (Author/JAC)

Questioning the K-ABC: What Does It Measure?
Peer reviewed Peer reviewed
Keith, Timothy Z. – School Psychology Review, 1985
Three levels from the Kaufman Assessment Battery for Children (K-ABC) standardization sample were randomly selected and their subtest score intercorrelations were subjected to factor analysis. The analyses yielded minor inconsistencies which suggest the instrument does not primarily measure simultaneous and sequential processing and achievement as…
