Abstract

Background: Confrontational naming test is useful in evaluating the language function. It reveals memory and cognitive processing dysfunctions in many neurologic diseases including dementia. Although the Korean version of the Boston Naming Test (K-BNT) has been a popular and useful test, it takes much time and effort in dementia patients of moderate to severe stage of disease or in elderly individual with low educational level. So we developed the Korean Naming Test (KNT).
Methods: KNT consists of relatively easy 40 items. Each item was familar materials around us and simplified figures with black thick line. Ninety two of probable Alzheimer’s patients received the Korean version of Mini-Mental State Examination (K-MMSE), the Korean version of expanded Clinical Dementia Rating Scale (CDR), K-BNT and KNT. We tested reliability and validity of KNT and also evaluated scores of the KNT along with CDR.
Results: The KNT correlated with K-BNT [0.75(p<0.01)], CDR [-0.49(p<0.01)], K-MMSE [0.55(p<0.01)]. The internal consistency was 0.91 (Cronbach´s alpha). The KNT score decreased as the disease progressed.
Conclusions: The KNT is a brief and good test for evaluating language function of moderate to severe dementia patients with low educational level. Also it is sensitive to mild stage of disease and has a excellent reliability and validity.
