Popis: | 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. |
