Abstract:
BACKGROUND: This study was done to evaluate the validity and reliability of the Kaigo-Yobo (K-Y) checklist in the Korean elderly population. METHODS: The study population included 283 men and women over 65 years who visited the three community senior's welfare centers located in Seoul and Gyeonggi province from March 29, 2011 to May 26, 2011. The Korean frailty index (FI), Japanese K-Y checklist, Cardiovascular Health Study frailty index (CHSFI), activities of daily living, and Korean Mini-Mental Status Examination were completed for each participant. Reliability was tested by internal consistency (Cronbach's alpha), as was the test-retest reliability, at a 2-week interval. Validity was tested by the area under the curve (AUC) from the receiver operating characteristics curve as a predictor of frailty according to the CHS criteria and the validity index estimated by the reliability index. RESULTS: The correlation coefficients between Korean FI and K-Y checklist, Korean FI and CHSFI, and K-Y checklist and CHSFI were 0.61, 0.43, and 0.44 respectively. The range of Kappa value for each item on the Korean FI was 0.28 to 0.60 and 0.19 to 0.65 for the K-Y checklist. Cronbach's alpha for the Korean FI was 0.58 and 0.64 for the K-Y checklist. The AUC for the Korean FI was 0.79, and 0.64 for the K-Y checklist. The validity index for the items on the Korean FI ranged from 0.28-0.53 to 0.60-0.78 and 0.19-0.44 to 0.65-0.81 for the K-Y checklist. CONCLUSION: The K-Y checklist is a valid and reliable instrument to measure frailty in the Korean elderly population. Follow-up studies are needed.
