A meta-analysis of the stability of low IQ (IQ less than 80) was performed on IQ tests that have been commonly used--tests that were derived by D. Wechsler (1949, 1955, 1974, 1981, 1991, 1997) and those based on the Binet scales (L. M. Terman, 1960; L. M. Terman & Merrill, 1972).

The validity of a technique for estimating premorbid intellectual functioning based on Wechsler Adult Intelligence Scale-Revised (WAIS-R) subtest performance and demographic information used in best-performance fashion was investigated with the 1,880 individuals from the WAIS-R standardization sample. Results support use of the approach. (SLD)
