Abnormal and Reliable Differences Among Wechsler Memory Scale—Revised Subtests.
Standardization data for the Wechsler Memory Scale—Revised (WMS—R) were used to generate confidence intervals for the statistical abnormality of differences between scales. Tables are provided for evaluation of material-specific rates of forgetting on the Logical Memory and Visual Reproduction subtests, adequacy of overall retention as reflected by contrasts between the General and Delayed Memory Indexes, and test–retest changes on the WMS—R scales. Confidence intervals derived from reliability and abnormality data are compared. The clinical significance of a discrepancy between scales may be better addressed by reference to information about the latter probability.
