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.
我们对101名年龄较大的正常个体（平均年龄 = 67.1岁）组成的样本，检验了韦氏成人智力量表修订版（WAIS-R）言语智商、操作智商和全量表智商的1年重测信度。相应的皮尔逊积差相关系数分别为0.86、0.85和0.90。WAIS-R分测验的重测信度系数中位数为0.71。言语-操作差异的重测信度为0.69。这些数据表明，在这个重测间隔内，年龄较大的正常个体的智商分数是可靠的，但对分测验分数和言语-操作差异的可靠性则信心较低。
