Background: Since April 2007, the Korean Ministry for Health, Welfare, and Family Affairs has been performed a general health screening on 40 and 66 years old people who are facing their middle and old ages. The checkup list for 66 years old has been included KDSQ-P which consists of the 5 questions for detecting a person who needs KDSQ-C, screening tests for dementia. The purpose of this study is to investigate the validity of KDSQ-P.
Methods: From September 1 to October 7, 2007, total 164 elderly subjects were selected and an inclusion criterion was only applied to the age over sixty. We select subjects who visited general health screening centers of Gangneung Asan hospital and the department of family medicine of Asan Medical Center and who are people
in the community. All subjects answered both KDSQ-P and KDSQ-C by self-report. For the validation of the KDSQ-P, KDSQ-C was used as a gold standard.
Results: The positive rates of the KDSQ-P were 50.0%, 39.6% for the cut-off point 3, 4 respectively. The positive rate of the KDSQ-C was 38.4%. The cut-off point 3, 4 for the KDSQ-P produced sensitivities of 87.3%, 73.0% and specificities of 73.3%, 81.2% respectively.
Conclusions: The cut-off point 4 which was chosen by the Korean Ministry for Health, Welfare, and Family Affairs has low sensitivity. But considering side-effect of screening for dementia, the score 4 is suitable as the best cut-off points for detecting a person who needs a screening tests for dementia.
