Wechsler-Bellevue Intelligence Scale-R

The WAIS-R was published in 1981 and consisted of six verbal and five performance subtests. The verbal tests were: Information, Comprehension, Arithmetic, Digit Span, Similarities, and Vocabulary. The Performance subtests were: Picture Arrangement, Picture Completion, Block Design, Object Assembly, and Digit Symbol. A verbal IQ, performance IQ and full scale IQ were obtained.

This revised edition did not provide new validity data, but used the data from the original WAIS; however new norms were provided, carefully stratified.
