Geneva ABSTRACT J Korean Neuropsychiatr Assoc Vol 38, No 6, November, 1999 Reliability and Validity of the Korean Version of Short Blessed TestSBT-K as a Dementia Screening Instrument Dong Young Lee, M.D., Jong Choul Yoon, M.D., Kang Uk Lee, M.D., Jin Hyeong Jhoo, M.D., Ki Woong Kim, M.D., Ph.D., Jung Hie Lee, M.D., Ph.D., Jong Inn Woo, M.D., Ph.D. Department of Neuropsychiatry, Seoul National University Hospital Neuroscience research institute, Seoul National University, College of Medicine, Seoul We aimed to develop the Korean version of Short Blessed testsbt-k by analyzing its reliability and validity, showing its usefulness as a dementia screening instrument. The translation, including back translation procedure, was carried out, keeping the basic structure of SBT. SBT-K. The Korean Version of Blessed Dementia Scale-Activity of Daily LivingBDS-ADL- K and Clinical Dementia Rating ScaleCDR were administered to 224 dementia patients and 191 control subjects, and The Korean Version of Consortium to Establish a Registry of Alzheimer s Disease- Mini-Mental State ExaminationCERAD-MMSE-K was to 157 patients and 167 controls. The correlation of SBT-K scores between two raters, correlation between the test and retest after one month, and its internal consistency were analyzed. To verify the concurrent validity of SBT-K, its correlation with each testcerad-mmse-k, BDS-ADL-K, and CDR was analyzed. The sensitivity and specificity for each cut-off point of SBT-K were calculated and the Receiver Operator CharacteristicROC curve analysis was done to get its optimal cut-off point. SBT-K was found to have significantly high internal consistency, inter-rater reliability, and test-retest reliability. The significant correlation of SBT-K with each test described above was also shown. Its optimal cut-off point was estimated as 10/11, and the sensitivity and specificity were 0.85 and 0.90, respectively. The ROC curve analysis indicated that the diagnostic efficiency of SBT-K was comparable with CERAD-MMSE-K. We conclude that SBT-K has not only high reliability and validity, but also usefulness as a screening instrument for dementia. KEY WORDSDementia Screening instrument SBT-K Reliability Validity. 1374
