Comparisons are made between the results given by two formulae for the reliability of the difference between an individual subtest score and the average subtest score on a scale to which that subtest belongs. For the WAIS-R and the WISC-R, the correct reliabilities reported here are appreciably higher than the incorrect reliabilities reported previously, and the apparent reversal of this result for the WPPSI is explained as an artifact. Even the correct reliabilities are very low, however, more than three-quarters of them below .70.
针对某个分测验分数与该分测验所属量表的平均分之间差异的信度，对两个公式给出的结果进行了比较。对于韦氏成人智力量表修订版（WAIS-R）和韦氏儿童智力量表修订版（WISC-R），此处报告的正确信度明显高于先前报告的错误信度，而韦氏幼儿智力量表（WPPSI）的这一结果明显反转则被解释为一种假象。然而，即使是正确的信度也非常低，其中超过四分之三低于0.70。
