Equations for prorating the Wechsler Memory Scale--III (WMS-III) Index scores were derived and validated on a sample of 252 mixed clinical cases. Regression equations were performed using age-scaled scores as predictors and the sum of age-scaled scores for Immediate Memory (IM) and General Memory (GM) as the criteria. Including Logical Memory and Verbal Paired Associates with either Faces or Family Pictures resulted in estimated scores that accounted for 95% to 97% of the variance for IM and GM. Over 80% of these cases had estimated sum of scaled scores that fell within 3 points of actual sum of scaled scores, within 1 standard error of measurement. When only Logical Memory and Verbal Paired Associates were included, estimations accounted for only 87% of the variance, and only 60% of the estimated scores fell within 3 points of actual sum of scaled scores. The regression equations are presented, as are the confidence intervals derived from a bootstrapping procedure that created 15,000 different samples.
推导出了韦氏记忆量表第三版（WMS - III）指数得分的按比例计算方程，并在252例混合临床病例样本上进行了验证。使用年龄量表得分作为预测变量，以即时记忆（IM）和一般记忆（GM）的年龄量表得分总和作为标准进行回归方程分析。将逻辑记忆和言语配对联想与面孔或家庭图片相结合，得出的估计得分占IM和GM方差的95%至97%。超过80%的这些病例的估计量表得分总和在实际量表得分总和的3分范围内，即在测量的1个标准误差内。当仅纳入逻辑记忆和言语配对联想时，估计值仅占方差的87%，且只有60%的估计得分在实际量表得分总和的3分范围内。文中给出了回归方程以及通过创建15,000个不同样本的自抽样程序得出的置信区间。
