Abstract

Background : Clinicians broadly accept the Global Deterioration Scale (GDS) as a staging measure for dementia. The aim of this study is to test the inter-rater reliability and concurrent validity of the Korean version of GDS. Methods : Participants included 34 subjects without dementia and 41 patients with Alzheimer s disease, in addition to 37 patients with vascular dementia. A rater, using a semi-structured clinical interview, interviewed the participants and their informed collateral sources. To obtain the concurrent validity, all participants received the Korean Mini-Mental State Examination (K-MMSE), the Korean version of Syndrome Kurz Test (K-SKT) and a 15-items abbreviated Korean-Boston Naming Test (K-BNT) on the same day. We also tested the inter-rater reliability among the four raters using a videotape design. Results : The agreements of the overall GDS ratings by the four raters were high (k, 0.93-1.0). GDS correlated significantly with K-MMSE, K-SKT, and the abbreviated K-BNT and Clinical Dementia Rating scale. Conclusion : The Korean version of GDS may be a reliable and valid tool to be used as a staging measure for Korean patients with Alzheimer s disease as well as vascular dementia.Key Words : GDS, Dementia, Validity, Alzheimer s disease, Vascular dementia
