Abstract
We examined the 1-year test-retest reliability of WAIS-R Verbal, Performance, and Full-Scale IQs in a sample of 101 older normal individuals (mean age = 67.1). The respective Pearson rs were .86, .85, and .90. The median retest reliability coefficient for the WAIS-R subtests was .71. The test-retest reliability for the Verbal-Performance Discrepancy was .69. These data indicate that IQ scores are reliable in older normal individuals for this retest interval, but less confidence can be placed in the reliability of subtest scores and the Verbal-Performance Discrepancy.Mesh:
