This paper presents the Delayed Memory Index (DMI) as an alternative to the General Memory Index (GMI) of the Weschler Memory Scale-Third Edition (WMS-III). The WMS-III Immediate Memory Index (IMI) and the GMI are not parallel in structure, making a direct comparison between these index scores (i.e., immediate vs. delayed memory variables) difficult. The IMI is composed of the sum of scaled scores of four subtests (Logical Memory I, Verbal Paired Associates I, Faces I, and Family Pictures I) while the GMI is composed of the sum of scaled scores of five subtests (Logical Memory II, Verbal Paired Associates II, Faces II, Family Pictures II and Auditory Recognition Delayed). Inclusion of Auditory Recognition Delayed in the GMI is also problematic as it is highly skewed and limited by extreme ceiling effects (see Tulsky, Chiaravalloti, Palmer, & Chelune, 2003). To remedy these problems, we present a new index score that does not include auditory recognition, the Delayed Memory Index. Normative tables for the new Delayed Memory Index based on the inclusion of the Faces subtest, or alternatively the Visual Reproduction subtest, are presented, and initial estimates of their psychometric properties are described.
本文提出了延迟记忆指数（DMI），作为韦氏记忆量表第三版（WMS-III）一般记忆指数（GMI）的替代指标。WMS-III即时记忆指数（IMI）与GMI在结构上不平行，导致这些指数分数（即即时记忆变量与延迟记忆变量）之间难以进行直接比较。IMI由四个分测验（逻辑记忆I、言语配对联想I、面孔I和家庭图片I）的量表分数总和组成，而GMI由五个分测验（逻辑记忆II、言语配对联想II、面孔II、家庭图片II和听觉识别延迟）的量表分数总和组成。GMI中包含听觉识别延迟也存在问题，因为它高度偏态且受到极端天花板效应的限制（见Tulsky、Chiaravalloti、Palmer和Chelune，2003）。为解决这些问题，我们提出了一个不包括听觉识别的新指数分数，即延迟记忆指数。给出了基于包含面孔分测验或视觉再生分测验的新延迟记忆指数的常模表，并描述了其心理测量学特性的初步估计。
