- Abstract
This study compared the factor structure of the translated Wechsler Memory Scale-III (WMS-III), which is the latest available version in Norway, with the original U.S. version. A sample of 122 healthy, elderly Norwegians (mean age: 74; standard deviation ¼ 8.8) completed the WMS-III. The factor structure of the translated WMS-III was tested, using Confirmatory Factor Analysis, with comparison of model fit based on five a priori hypothesized models. Several model fit indices pointed to a three-factor model (working memory, visual memory, and auditory memory) providing the best fit to the data. Our study supports updated findings of the original WMS-III in nonclinical samples and suggests that the translated version is structurally equal to the original. The study supports the cross-cultural validity of the WMS-III.However, based on the present data, one might expect scores on the Family Pictures subtest to fall below scores on other WMS-III subtests in elderly Norwegians.
