The study compared the relationships of more easily administered intelligence screening instruments with the Wechsler Intelligence Scale for Children (WISC) to determine the validity of the Peabody Picture Vocabulary Test, the Slosson Intelligence Test, and the Raven Progressive Matrices among reading disabled children. The screening measures were administered by a trained clinician to 28 children referred to a university reading clinic for diagnosis of reading problems. The findings indicated that the Peabody, the Slosson, and the Raven scores all correlated substantially with the WISC scores and were measuring essentially the same thing as the WISC. However, the multiple correlations were not significantly higher than the single correlations. One instrument, the Slosson, appeared to be most comparable with the WISC and was suggested for general use in screening the intelligence of many disabled readers. (Author/LL)
