Abstract:
OBJECTS: We developed the Korean version of Hasegawa Dementia Scale(HDS-K) by translating the revised Hasegawa Dementia Scale(HDS-R) which is known to be a useful brief screening instrument for dementia. MATERIALS AND METHODS: The translation was carried out keeping the basic structure of Revised Hasegawa Dementia Scale(HDS-R). HDS-K, along with MMSE-KC, SBT-K and CDR, were administered to 174 dementia patients and 160 elderly control subjects. Cronbach alpha coefficient, inter-rator reliability, and test-retest reliability of HDS-K were examined. The correlations of MMSE-KC, SBT-K and CDR with HDS-K were also examined to confirm the validity of HDS-K. Cut-off scores for dementia were estimated by Receiver Operator Characteristic(ROC) curve anslyses. By comparing Area Under Curve(AUC), the diagnostic efficiency of HDS-K was compared with those of MMSE-KC and SBT-K. RESULTS: 1) HDS-K was found to have significantly high internal consistency(Cronbach alpha coefficient=0.948, <0.01), inter-rater reliability(Pearson correlation coefficient=0.999, <0.01) and test-retest reliability(Pearson correlation coefficient=0.848, <0.01). 2) All the correlations of HDS-K with MMSE-KC, SBT-K and CDR were significant indicating that HDS-K has good concurrent validity. Its optimal cut-off point for dementia was estimated as 15/16, where the sensitivity and specificity were 0.950 and 0.902, respectively. 3) The ROC curve analysis indicated that the diagnostic efficiency of HDS-K(AUC=0.972) was comparable with MMSE-KC(AUC=0.951) and SBT-K(AUC=0.963). CONCLUSION: We conclude that HDS-K is a reliable, valid, and useful screening instrument for dementia.
