Application of Cluster Analysis to Identify More Homogeneous Groups of Children with Learning Problems.
Luick, Anthony Harlan
A multi-faceted study followed up 800 children originally administered SCREEN, a comprehensive early identification screening battery. Ss were given an individually administered diagnostic battery: The Illinois Test of Psycholinguistic Abilities (ITPA), The Wechsler Intelligence Scale for Children (WISC) Verbal Scale, The Beery Visual Motor Integration Test (VMI), and an Experimental Phonetics Test. Factor Analysis on the SCREEN battery and on the ITPA within the "high risk" sample yielded more complex factor structures which provided substantial construct validity for both tests. Evidence suggested that the SCREEN battery is an adequate to substantial predictor of achievement tests. Concurrent and predictive validity studies indicated that the ITPA and PIAT (Peabody Individual Achievement test) were better predictors of school achievement than were the WISC scale and the VMI. Separate cluster analysis of the SCREEN battery and ITPA revealed homogeneous subclusters of Ss who displayed specific patterns of deficits. Results demonstrated that there is a reliable and valid technology for identifying relatively homogeneous groups of learning problem children. (Author/CL)
