영문 초록

Purpose: The purpose of this study was to validate the Korean version of the mild cognitive impairment questionnaire (K-MCQ) to assess quality of life of older adults with mild cognitive impairment. Methods: The translation and linguistic validation process was completed according to Oxford University’s guidelines and the K-MCQ’s developer. The K-MCQ was expertly reviewed to calculate the content validity index (CVI). After pilot testing, the K-MCQ’s final format was applied to 130 adults with mild cognitive impairment for reliability and validity testing using item analysis, exploratory and confirmatory factor analysis, and internal consistency. The SF-12 is an established quality-of-life instrument that measures criterion validity and the MoCA-K measures concurrent validity. Results: The K-MCQ consisted of 13 items on a 5-point Likert scale and two factors (practical and emotional concerns) explained 67.0% and 72.9%, respectively. The K-MCQ verified discriminant validity in confirmatory factor analysis, criterion validity with a significant correlation with the SF-12, and concurrent validity with a significant correlation with cognitive function. Reliability was confirmed with Cronbach’s ⍺=.92. Conclusion: These findings indicate that the K-MCQ is a reliable and valid measure of quality of life, which can assess quality of life of older Korean adults with mild cognitive impairment.
