전산화된 치매선별 검사(Computerized Dementia Screening Test: CDST)의 규준 연구 = Normative Study on the Computerized Dementia Screening Test(CDST)

다국어 초록 (Multilingual Abstract)

This study purported to develop norms for the Computerized Dementia Screening Test (CDST) in elderly Korean population. In order to develop valid norms, effects of demographic variables on the test performance were examined as well as the validity of the test itself. Normative sample consisted of one hundred twenty elderly volunteers whose ages were between 55 and 84 living in Seoul, Kyungki-do, and Kwangju. Age and education proved to be significant factors influencing CDST performance, while gender and literacy proved to be of minimal importance. Correlation coefficient between the CDST and the K-DRS performance was .53 (p < .001). Logistic regression analysis with AD patients and normal participants matched for age and education produced superb sensitivity and specificity of 92%. A rank method was utilized to develop standardized scores that would provide cut-off scores which can be utilized to a wider range of elderly samples. These cut-off scores based on standardized scores yielded excellent sensitivity and specificity of 88%, which were superior to cut-off scores based on raw scores. A multi-component decision-making procedure introduced in this study used in conjunction with the standardized scores appear to be a more informative and valid approach for screening dementia.
