This study examined interrater reliability of Russell's revision of the Wechsler Memory Scale logical memory using an explicit scoring method in a male medical/psychiatric population. Secondly, it examined whether the ratio of full to half-credit scores can be used to differentiate unimpaired patients from patients with documented cerebral dysfunction. Twenty-five unimpaired and 25 brain-impaired patients matched for age and education were used. Pearson correlations indicate excellent interrater reliability. t-tests indicate that the groups were not significantly different from the ratio of full- to half-credit responses on immediate memory, but were significantly different on delayed memory. A posteriori analyses indicated that a small ratio score (less than 3) on delayed recall classified patients with modest success. Results indicated that brain-impaired and unimpaired patients not only differ in regard to level of recall performance, but also differ in regard to pattern of recall performance. Cross-validation of these results is suggested.
本研究采用明确评分方法，在男性医学/精神科人群中检验了韦氏记忆量表逻辑记忆部分经拉塞尔修订后的评分者间信度。其次，研究了满分与半分得分的比例是否可用于区分未受损患者和有记录的脑功能障碍患者。研究使用了25名未受损患者和25名年龄及受教育程度匹配的脑损伤患者。皮尔逊相关性表明评分者间信度极佳。t检验表明，两组在即时记忆中满分与半分回答的比例上无显著差异，但在延迟记忆上有显著差异。事后分析表明，延迟回忆中较低的比例分数（小于3）能成功区分出部分患者。结果表明，脑损伤患者和未受损患者不仅在回忆表现水平上存在差异，在回忆表现模式上也存在差异。建议对这些结果进行交叉验证。
