- Abstract
- "Background : Dementia Screening Questionnaire is sensitive to detect early dementia patients and is not influenced
by age and educational level. We conducted a case-control study to assess the validity and reliability of the Korean
Dementia Screening Questionnaire (KDSQ) for the diagnosis of early dementia. Methods : We developed KDSQ in a
semi-structured manner with the questionnaire of 15 items about cognitive dysfunctions and 5 items of ischemic and
depression scales respectively to evaluate the possibility of vascular dementia and degree of depression. It was administrated
to informants of 72 dementia patients (39 Alzheimer s disease, 33 vascular dementia) with Clinical Dementia
Rating (CDR) scales of 0.5, or 1.0 and to those of 66 hospital control subjects. Test-retest data for the KDSQ were
obtained from informants within a time interval of 20.82 days. Results : The KDSQ was not influenced by education
level, age, or sex. KDSQ score correlated with the K-MMSE (r=-0.75) and Short form Samsung Dementia
Questionnaire (r=0.80). The area under the receiver operating characteristic curve for the KDSQ was 88.9%
(S.E.=0.028). KDSQ depression score was correlated with Geriatric Depression Scale (r=0.34). With respect to a diagnosis
of dementia, the KDSQ (cut-off point 6) had a sensitivity of 79% and a specificity of 80%. The KDSQ was found
to have a high test-retest reliability (r=0.81) Conclusions : The KDSQ has high validity and reliability for the diagnosis
of early dementias. It may be a useful tool to screen early stage of dementias.Key Words : Dementia, Screening, Questionnaire, Alzheimer s disease, Vascular dementia"
