|
Background: Korean Instrumental Activities of Daily Living(K-IADL) scale was developed to measure the elderly function. The aim of the present study was to establish the validity and reliability of K-IADL 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 0.938. 2 weeks test-retest correlations in all 10 items were higher than 0.674. Interrator agreements were high in all 10 items(H=0.808∼0.947). Normal control group had lower scores than patients group in all 10 items(p=0.000). Correlation coefficient between K-IADL score and brain-disability grade was between -0.336(laundry) and -0.663(using transportation)(p=0.000).
Conclusions: Korean Instrumental Activities of Daily Living(K-IADL) scale is a valid and reliable instrument. In the future, the studies showing an association between K-IADL and mortality, prognosis are needed.
