Abstract

BACKGROUNDS: Korean Activities of Daily Living(K-ADL) scale was developed to measure the elderly function. The aim of the present study was to establish the validity and reliability of Korean Activities of Daily Living(K-ADL) scale.
METHODS
Clinical validity and convergent validity was tested. Reliability was tested by internal consistency(Cronbach's alpha), two weeks test-retest method, and interrator correlation.
RESULTS
Cronbach's alpha was 0.937. 2 weeks test-retest correlations in all 7 items were higher than 7.0. Interrator agreements were high in all 7 items(h=0.86~1.0). Nonnal control group had lower scores than patients group in all 7 items(p=0.000). Correlation coefficients between K-ADL score and braindisability grade was between -0.465(eating) and -0.696(bathing)(p=0.000).
CONCLUSIONS
Korean Activities of Daily Living(K-ADL) scale is a valid and reliable instrument. In the future, the studies showing an association between K-ADL and mortality, prognosis are needed.
