The psychometric structure of the Wechsler Memory Scale (WMS) and its relationship to the revised Wechsler Adult Intelligence Scale (WAIS-R) were studied in an outpatient population of 103 individuals with low Full Scale IQ scores (M = 71). We found that the age correction of the WMS scores gave memory quotients (WMQ) equivalent to WAIS-R FSIQ scores, but our findings also raised problems of interpretation. If the usual rule of thumb of a 12-point discrepancy between the MQ and the FSIQ were applied, the WMS might be relatively insensitive to memory impairment in this low-IQ clinical population, in which more numerous cases of impairment could be expected. Principal components analysis of the WMS raw scores and three WAIS-R scores included as reference variables yielded five orthogonal factors: Attention/Concentration; Visual Reproductions; New Verbal Learning; Well-learned Semantic Knowledge; and Intelligence. We argue that raw scores on the WMS should be reported to optimize possible diagnostic specificity and to align the WMS with experimental and clinical research in various types of memory functioning and impairment.
在一个由103名全量表智商分数较低（M = 71）的个体组成的门诊人群中，研究了韦氏记忆量表（WMS）的心理测量结构及其与修订后的韦氏成人智力量表（WAIS-R）的关系。我们发现，WMS分数的年龄校正得出的记忆商数（WMQ）与WAIS-R全量表智商分数相当，但我们的研究结果也引发了解释方面的问题。如果应用记忆商数与全量表智商之间相差12分这一通常的经验法则，WMS可能对这个低智商临床人群中的记忆损害相对不敏感，而在该人群中预计会有更多的损害病例。对WMS原始分数以及作为参考变量纳入的三个WAIS-R分数进行主成分分析，得出了五个正交因子：注意力/专注力；视觉再现；新言语学习；熟练掌握的语义知识；以及智力。我们认为，应该报告WMS的原始分数，以优化可能的诊断特异性，并使WMS与各类记忆功能和损害的实验及临床研究保持一致。
