Based on the present findings, it appears that all the Taiwan WAIS-Ⅲ working memory index, the single Arithmetic and the Digit Span subtests, and the span scores of the Digit Span subtest could adequately discriminate individuals without working memory impairment, but had poor sensitivity on detecting the patients who evidenced working memory impairment. Accordingly, it is suggested that clinicians should gauge the working memory index by a composite of the Arithmetic, the Digit Span, and the Letter-Number Sequencing subtests if possible. Otherwise, a caveat should be taken with care to interpret the working memory index, as estimated by a composite of the Arithmetic and the Digit Span subtests, because the chance of the increasing false negative rate becomes ineludible.

综合上述，显见WAIS-Ⅲ中文版中之工作记忆指数、单一算术及单一记忆广度分测验、或记忆广度分测验之各项广度值在区分患者有无工作记忆功能异常上皆拥有良好之区辨力，但对侦测工作记忆功能异常患者的敏感度普遍不佳，建议临床工作者应尽量取得算术、记忆广度、与数－字序列等三项分测验组合所估算之工作记忆指数；若在有限条件下，临床工作者仅能以算术与记忆广度两项分测验之组合所估算之工作记忆指数来评估受试者工作记忆，应留意假阴性比例上升的问题。
