差异评分的可靠性公式用于根据各组成部分的可靠性和相关性来估计 Delis-Kaplan 执行功能系统（D-KEFS；Delis 等人，2001）对比测量的可靠性。反过来，这些可靠性被用来计算测量的标准误差。大多数对比测量的可靠性较低：在本研究中计算的 5 1 个可靠性系数中，没有一个超过 0.7，因此都未能满足心理测量领域各专家提出的可接受可靠性的任何标准。对比评分的平均可靠性为 0.27，中位可靠性为 0.30。测量的标准误差很大，并且在许多情况下等于或仅略小于对比分数的标准差。结果表明，目前 D-KEFS 对比措施不应用于神经心理学决策。 (JINS, 2008, 14, 1069-1073.)
A formula for the reliability of difference scores was used to estimate the reliability of Delis-Kaplan Executive Function System (D-KEFS; Delis et al., 2001) contrast measures from the reliabilities and correlations of their components. In turn these reliabilities were used to calculate standard errors of measurement. The majority of contrast measures had low reliabilities: of the 5 1 reliability coefficients calculated in the present study, none exceeded 0.7 and hence all failed to meet any of the criteria for acceptable reliability proposed by various experts in psychological measurement. The mean reliability of the contrast scores was 0.27, the median reliability was 0.30. The standard errors of measurement were large and, in many cases, equaled or were only marginally smaller than the contrast scores' standard deviations. The results Suggest that, at present, D-KEFS contrast measures should not be used in neuropsychological decision making. (JINS, 2008, 14, 1069-1073.)
