The study involving 40 learning disabled children (6-8 years old) investigated the relationships between the various indexes of the McCarthy Scales of Children's Abilities (MSCA) and the scales of the Wechsler Intelligence Scale for Children-Revised (WISC-R), and the comparability between the MSCA General Cognitive Index and the WISC-R Full Scale…

Comparison of scores on the Kaufman Assessment Battery for Children and the Wechsler Intelligence Scale for Children-Revised of 67 students (ages 6-12) referred for possible learning disabilities found strong relationships among all the global standard scores on both instruments with different score patterns for those with severe disabilities.…

This article reviews the validity of models based on (a) aptitude--achievement discrepancies, (b) low achievement, (c) intraindividual differences, and (d) response to instruction for the classification and identification of learning disabilities (LD). Models based on aptitude--achievement discrepancies and intraindividual differences showed…

The concurrent validity of the Peabody Individual Achievement Test (PIAT) with 45 learning disabled children (7- to 12-years-old) was investigated using the California Achievement Test (CAT), the Wide Range Achievement Test (WRAT), and teacher ratings as criterion measures. (Author/DB)

To analyze differential diagnostic efficiency of the Revised Illinois Test of Psycholinguistic Abilities (a measure designed to assess strengths and weaknesses of learning disabled children), the Kelley procedure for estimating the proportion of differences in excess of chance was applied to the standardization data.

The Pre-Reading-Screening Procedures and the Slingerland Screening Tests for Identifying Children with Specific Language Disability were administered to 1021 grade one to six students. Results indicated that reliability and validity coefficients were acceptable and that educational programing decisions could confidently be based on the test…

Evaluated was whether factor analysis of the 12 Illinois Test of Psycholinguistic Abilities subtest scores earned by 90 underachieving children (between 5 and 10 years of age) would support the dimensions of psycholinguistic processes, organizational levels, and communication channels as described in the clinical model of the instrument.

To examine the concurrent and construct validity of the Slingerland Screening Tests (SST) for Children with Specific Language Disability in the assessment of learning disabilities, 382 children in grades 1 through 4 were given both the SST and an IQ test. The SST errors were significantly negatively correlated with IQ scores. (Author)

The Visual Aural Digit Span Test (VADS Test), developed and standardized as a diagnostic test for learning disabilities in kindergarten to sixth grade, was adopted for use with seventh graders. An investigation of the relationship between the VADS Test scores and reading achievement showed the validity of the test for middle school pupils. (Author)

The study investigated the concurrent validity of the Peabody Individual Achievement Test (PIAT) with 60 learning disabled adolescents. Findings generally supported the concurrent validity of the PIAT as a measure of academic achievement with secondary learning disabled students. (SBH)

This study compared level of agreement among four models used to diagnose learning disabilities (LD), including the simple discrepancy, intraindividual, intellectual ability-achievement, and underachievement models. The simple discrepancy model diagnosed significantly more college students with LD than the others. The highest agreement was between…

The Basic School Skills Inventory (BSSI), a longitudinal rating scale, and the First Grade Screening Test, a group readiness test, were administered to 159 kindergarteners. (SBH)
