A Review of Sattler's Modifications of Standard Intelligence Tests for Use With Handicapped Children
Robert G. Harrington
In this review, the problems encountered by school psychologists in performing an unbiased assessment of the intelligence of physically handicapped children are discussed. Issues in the validity and reliability of clinical adaptations of existing intelligence tests are raised. Finally, Sattler’s research on a non-verbal form of selected Stanford-Binet tests and WISC subtests to assess normal, mentally retarded and cerebral-palsied children is presented. It is concluded that Sattler’s research represents not only an advance in experimental design over previous investigations but also demonstrates that at least some modified tests may serve as substitutes for standard tests with handicapped children. Future research into the predictive validity of the tests as well as certain modifications of some of the multiple-choice items are suggested. Overall, however, the results of Sattler’s work are seen as very encouraging.
