Abstract

Concurrent validity of a seven-subtest short form (7SF) of the revised edition of the Wechsler Adult Intelligence Scale (WAIS-R) was examined in 733 cognitively normal adults between 56 and 99 years of age who participated in Mayo's Older Americans Normative Studies (MOANS). Pearson correlation coefficients between actual and prorated MAYO Verbal, Performance, and Full Scale IQ scores ranged from r = .93 to r = .97. Actual and prorated FSIQ scores differed by 6 points or less for 98% of participants, and the observed deviations did not vary as a function of age. These results support the use of this WAIS-R short form to prorate MAYO IQ scores for older adults.
