Hierarchical Factor Structure of the Wechsler Adult Intelligence Scale-Revised.
Peer reviewed Peer reviewed
Blaha, John; Wallbrown, Fred H. – Journal of Consulting and Clinical Psychology, 1982
Obtained a hierarchical factor solution on the Wechsler Adult Intelligence Scale-Revised (WAIS-R) subtest intercorrelations for the nine age groups included in the standardization sample. Findings support the validity of the WAIS-R as a measure of general intelligence and the validity of maintaining separate Verbal and Performance IQs. (Author)

Differential WAIS/WAIS-R IQ Discrepancies among Institutionalized Mentally Retarded Persons.
Peer reviewed Peer reviewed
Goldman, Jeri J. – American Journal of Mental Deficiency, 1987
Scores on the Wechsler Adult Intelligence Scale (WAIS) were compared with reevaluation scores obtained four years later on the WAIS-Revised for a group of 108 mildly and moderately retarded adults. The moderately retarded subgroups (N=22) demonstrated significantly higher WAIS-R intelligence quotients. Implications for use of the WAIS-R are…
