This paper assesses to what extent the ICD-10 (International Classification of Diseases) criteria differ from other diagnostic systems for Asperger syndrome. The paper concludes that the variety of criteria in use makes interpretation of research findings difficult and that the ICD-10 criteria are the most stringent and closest to Hans Asperger's…

Data on 52 individuals with and 62 individuals without autism were analyzed to assess developmental aspects of the DSM-III-R (Diagnostic and Statistical Manual III, Revised) diagnostic system. Findings indicate that DSM-III-R criteria are more developmentally oriented and more behaviorally specific than previous criteria, but the diagnostic…

The concurrent validity of three types of reading ability assessments was evaluated with 312 Australian primary-level children. Results suggest that the nature of the skills required for success in reading changes in the primary years, and that both teacher-based and test-based assessments concur more closely as children progress through the…

The concurrent validity of the Battelle Developmental Inventory was explored by correlating Battelle results with scores from the Bayley Scales in 30 infants with known or suspected disabilities. Both the pattern and strength of the obtained correlations support use of the Battelle to measure development in infants with handicaps. (Author/JDD)

A total of 413 students in grades 1-6 were administered the Basic Academic Skills Samples, the Gates-MacGinitie Reading Tests, and the Metropolitan Achievement Test. Although the relationships among the three tests were reasonably strong, it appeared that the measures did not identify identical populations of at-risk students. (Author/JDD)

Learning disabled, emotionally disturbed, and unclassified male students originally tested with the Elizur Test of Psycho-Organicity (ETPO) when they were 6 to 11 years of age (time 1), were reassessed four years later (time 2) with the same instrument. Examinees were required to duplicate geometric and colored block designs, and to memorize five…

The Learning Disability Index (LDI) was validated by an examination for mean profiles and demographic characteristics of high and low LDI subsets of the standardization sample of the Wechsler Intelligence Scale for Children-Revised. The LDI continuum was found to measure Third Factor strengths/weaknesses as much as verbal-performance…

A longitudinal study was designed to develop and evaluate a screening instrument of developmental delay based on parental assessment of 18-month-old children. The reliability and validity of a parental screening instrument based on the Griffiths Mental Developmental Scale was investigated with a sample of 2,783 Swedish children out of a population…

The Battelle Developmental Inventory (BDI) was administered to 121 young children, and parents rated them with the Social Skills Rating System 2-3 years after entry into the study. Correlations between the two measures revealed very weak to modest relationships, providing limited support for the BDI as a predictive measure of future…

The Slosson Intelligence Test (SIT) and the Stanford-Binet, Fourth Edition (SBIV) were administered to 95 elementary students referred because of either learning problems or potential giftedness. SIT scores predicted SBIV verbal scores more accurately than composite scores. Overall the SIT predicted SBIV scores better for students with learning…

The paper reports on a 1 year followup study to establish the short term predictive validity of an early identification system used in London, Ontario (Canada) for kindergarten and first grade high risk students. Ratings of the students by the evaluation teams in January were compared with the students' actual placements as of the following…

To identify classroom behaviors that differentiate primary-level students with learning disabilities (LD) from their nondisabled peers, two scales of 83 items each were devised and piloted. Two subscales and 18 individual items were found to discriminate students later classified as LD and those referred but not subsequently classified as LD.…

This article, which introduces six papers on the validity of distinguishing subgroups of children with language and learning disabilities based on discrepancies between academic attainment and intelligence test scores, comments on the papers' diversity in samples, measurement characteristics, and statistical approaches and outlines the studies'…

This study, involving 1,069 children (ages 9-14) referred for evaluation of learning disability, used 3 definitions of reading disability to provide criteria for 5 groups of children based on discrepancy between intelligence quotient (IQ) and academic achievement. Results question the validity of segregating children with reading deficiencies…

Decisions based on the Fluharty Preschool Screening Tests and the Northwestern Syntax Screening Test (and their subtests) were compared to a validity criterion of passing or failing the Sequenced Inventory of Communication Development for 182 children aged 36-47 months. Validity differences were found that depended on test and subtest content.…
