Abstract

To date there has been a paucity of data that measure the test retest reliability of the WAIS. In the present study, 29 young male police applicants were given the WAIS, which was readministered after 20 wks. Reliability coefficients for the Full Scale, Verbal, and Performance IQs were: .91, .87 and .84, respectively, all significant at the .001 level. Retest reliability of all subtests but Similarities (p .01) also were significant at the .001 level. For the three Wechsler scales, mean and median gain was 5 IQ points. The range of gains for individual Ss was wider, however, which suggests that a few subjects have relatively large retest gains that can be attributed to error variance in a normal population over a short retest interval. There was no relationship between initial IQ and size of gain.
