Although delayed recall tasks are prominent features of the popular Wechsler Memory Scale-Revised (WMS-R), exploratory factor analyses consistently have failed to identify an associated delayed recall factor. The present study tested the hypothesis (Elwood, 1991b) that a delayed recall factor could be found by substituting percent retained (saving) scores for the existing WMS-R delayed recall subtest scores. Principal component analyses of age-corrected WMS-R immediate and save scores in a mixed clinical sample failed to find the hypothesized save factor. Both the scree and MAP tests retained one general memory factor, which accounted for 42.2% of the total variance. Independent statistical programs produced essentially equivalent results. Clinical implications of these findings are discussed.
尽管延迟回忆任务是广受欢迎的韦氏记忆量表修订版（WMS-R）的显著特征，但探索性因素分析一直未能识别出与之相关的延迟回忆因素。本研究检验了这样一个假设（埃尔伍德，1991b）：通过用保留百分比（保存）分数替代现有的WMS-R延迟回忆子测验分数，可以找到一个延迟回忆因素。在一个混合临床样本中，对经年龄校正的WMS-R即时和保存分数进行主成分分析，未能找到假设的保存因素。碎石图检验和MAP检验都保留了一个一般记忆因素，该因素占总方差的42.2%。独立的统计程序得出了基本相同的结果。文中讨论了这些发现的临床意义。
