Construct Validity of the ITPA
Peer reviewed Peer reviewed
Newcomer, Phyllis; And Others – Exceptional Children, 1974
The Illinois Test of Pscyholinguistic Abilities was administered to 167 normal intelligence children (mean age 112 months) and then factor analyzed to determine construct validity and the extent to which each subtest measures a discrete combination of the psycholinguistic dimensions of level, process, and channel.

What Does the Frostig DTVP Measure?
Peer reviewed Peer reviewed
Sabatino, David A.; And Others – Exceptional Children, 1974
Investigated with 129 kindergarten children were test-retest reliability and validity of the Developmental Test of Visual Perception (DTVP), and changes in factorial relationships among the five DTVP subtest after a 10-week use of the program of M. Frostig. (MC)

Learning Disability Classification by Bayesian Aggregation of Test Results
Peer reviewed Peer reviewed
DeRuiter, James A.; And Others – Journal of Learning Disabilities, 1975
Evaluated with 25 learning disabled (LD) and 25 non LD elementary level children was the Bayesian method to screen children for possible LD, an approach which uses the aggregation of data--objective test scores related to likelihood ratios and a known prior odds ratio. (Author/DB)

Relationships Between the WISC and the ITPA--A Multivariate Analysis
Elkins, J. – Slow Learning Child, 1973
Compared were the relationships between the Wechsler Intelligence Scale for Children and the Illinois Test of Psycholinguistic Abilities by means of the statistical methods of factor analysis and canonical correlation analysis as applied to scores of 63 children (mean age 7 1/2 years) referred for reading problems.

The Base Rate Problem and Its Consequences for Interpreting Children's Ability Profiles.
Peer reviewed Peer reviewed
Glutting, Joseph J.; McDermott, Paul A.; Watkins, Marley M.; Kush, Joseph C.; Konold, Timothy R. – School Psychology Review, 1997
Compares various base-rate procedures with statistical-significance testing approach used by psychologists. Nonlinear multivariate method is used to determine whether children with a learning disability or emotional disturbance are more likely to show unusual subtest patterns than are children from the normative sample of Wechsler Intelligence…

Learning Disabilities Empirical Research on Ethnic Minority Students: An Analysis of 22 Years of Studies Published in Selected Refereed Journals.
Peer reviewed Peer reviewed
Artiles, Alfredo J.; And Others – Learning Disabilities Research and Practice, 1997
A study analyzed 2,378 empirical articles on ethnic minority students published in two learning disability and two special education journals over a 22-year period (1972-94). Studies focused on assessment and testing, sensory-perceptual processing, and placement issues. The majority also compared ethnic groups, used quantitative approaches, and…

Proger, Barton B.; And Others – 1976
The problem of variability of data, even in presumable homogeneous subgroupings of handicapped children, which contaminates the results of many special education curriculum evaluation studies is examined with a study of 103 second-grade learning disabled students. The distortion of statistics calculated on samples of extreme variability; coupled…
