Objectives：Clinical utility of the Short Form of the Samsung Dementia Questionnaire (S-SDQ) as a screening instrument for Mild Cognitive Impairment (MCI).

Result of Receiver Operating Characteristic (ROC) analysis revealed that S-SDQ discriminated between the SMI and the MCI groups. Conclusion：S-SDQ may be a solution to the problem of contamination by education and age which affect traditional cognitive screening instruments like K-MMSE, and it may be a useful tool for screening MCI
