In this study, we examined the characteristics of reading disability (RD) in the seventh grade of the Greek educational system and the corresponding diagnostic practice. We presented a clinically administered assessment battery, composed of typically employed tasks, and a fully automated, computer-based assessment battery that evaluates some of…

Two studies addressing the clinical validity of discrepancy criteria for identification of children with developmental language disorders (DLD) are reported: one with 256 preschoolers clinically defined as DLD, and one with 363 8-year-old controls. Factors contributing to underidentification in Study 1 and overidentification in Study 2 are…

The reliability and validity of a revised version of the Reading History Questionnaire was examined using 84 adults from an ongoing study of familial dyslexia and the parents of 107 children from a longitudinal study of reading development. The results indicated that the questionnaire (appended to the article) is both reliable and valid. (Contains…

Three studies investigated the effectiveness of the Computer Assisted Reading Diagnosis, a diagnostic system based on "rauding" theory (a collection of theories, constructs, and equations developed to describe, explain, predict and control the ability to comprehend relatively easy sentences) and a causal model of reading achievement.…

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 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…

This study examined the utility of Wechsler's Deterioration Index, which compares short- and long-term memory capabilities. Three studies with a total of 120 children (ages 6-14) found that the index did not predict learning disability status but did distinguish children with attention deficit hyperactivity disorder from nondisabled children.…

A study examined the efficacy of the Restricted Academic Task in evaluating the effects of stimulant medication in 149 children (ages 5-17) with attention deficit hyperactivity disorder. The measure consists of standardized observation of a child performing an academic-like task, and was found to be both reliable and valid. (Author/CR)
