Factor analysis of WISC—R with deaf and hard-of-hearing children.

Abstract

The Wechsler Intelligence Scale For Children-Revised was factor analyzed on a sample of 368 hard-of-hearing and deaf children, ages 6 to 16 years. Two factors emerged and were labeled Language Comprehension (1) and Visual-Spatial Organization (v-s). The factor structure for the hard-of-hearing (n = 77) and deaf (n = 291) groups was identical. Deaf children of deaf parents earned significantly higher Verbal IQ and Performance IQ scores than did deaf children of hearing parents. There were no differences in IQ or subtest scores in interpreted versus signed administrations
