The regression-based discrepancy definition of learning disabilities has been suggested by Rutter and Yule as an improvement of the well-known and much criticized achievement-intelligence discrepancy definition, whereby the examinee's predicted reading attainment is substituted for the intelligence score in the discrepancy expression. Even though…

The comprehension section of the "Nelson-Denny Reading Test" (NDRT) is widely used to assess the reading comprehension skills of adolescents and adults in the United States. In this study, the authors explored the content validity of the NDRT Comprehension Test (Forms G and H) by asking university students (with and without at-risk…

This study examined concurrent and longitudinal relations for the "Get Ready to Read!" (GRTR) emergent literacy screener. This measure, within a battery of oral language, letter knowledge, decoding, and phonological awareness tests, was administered to 204 preschool children (mean age = 53.6, SD = 5.78; 55% male) from diverse…

The purpose of the study was to examine whether the Greek translation of the "Learning Disability Evaluation Scale" (LDES) can be used in the identification of learning disabilities. The LDES was completed by 165 teachers for one of their students, aged 5 to 14 years. The LDES was significantly correlated to students' grades in Math and…

Response to intervention (RTI) holds great promise for the early identification and prevention of reading disabilities. The success of RTI rests in part on the accuracy of universal screening tools used within this framework. Despite advancements, screening instruments designed to identify children at risk for reading disabilities continue to have…

Despite recent research findings that implicate a long list of student variables that predict reading success or failure, these predictor variables have not been considered in the context of contemporary models of multitiered schoolwide reading intervention. This longitudinal, retrospective study follows 668 kindergarten and first-grade students…

The study found that the Kaufman Assessment Battery for Children (K-ABC) was valid in predicting reading, mathematics, and written expression for Black, Hispanic, and White male students referred for special education services. The K-ABC scores were not valid predictors, however, of written language achievement for referred females. (Author/DB)

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.…

The study evaluated the construct validity of five perceptual traits with simulated work samples from the Jewish Vocational Service Work Sample System. Results with 36 learning disabled adolescents indicated that simulated work samples can be used as a diagnostic instrument for assessment of perceptual abilities in a vocational setting. (Author/DB)

The validity of using an analysis of patterns of performance on the Meeting Street School Screening test versus using the composite cutoff score for identification of learning disabilities was analyzed for 1,377 first graders. Use of subtest scatter predicted later learning disability placements less accurately than chance. (Author/DB)

An 18-item "Shortened Visuospatial Questionnaire" (SVS) was validated twice, first by verifying that children (ages 8-13) identified with the SVS questionnaire as having visuospatial learning disability (VSLD) (n=54) actually showed visuospatial deficits on psychometric evaluation, and second, by rating with the SVS a clinically identified…

Scores on the Holbrook Screening Battery, administered at age four, correctly predicted 89 percent of good readers and 75 percent of poor readers in a sample of 116 eighth graders. Characteristics differentiating good and poor readers included birth history, family history of learning disability, speech delay, and socioeconomic status. (Author/DB)
