ABSTRACT

Objective : The purpose of this study was to devise a checklist version of Korean version of Modified Barthel Index(K-MBI) and compare its reliability with the K-MBI. Methods : The subjects were 30 brain injury patients. We subdivided each subitem of the original K-MBI and created a checklist (so-called K-MBI checklist). We divided it into 2 groups: a newly developed K-MBI checklist, and the original K-MBI, with two randomly assigned occupational therapists for each group. The collected data were analyzed to ascertain the inter-rater reliability through an intraclass correlation coefficient (ICC) for the total test score and Kappa statistics for the subitems of the test. Results : The inter-rater reliability of the total test score was significantly high in both the K-MBI checklist group (ICC=.981) and the original K-MBI group (ICC= .973)(p<.001). For the internal constancy in the subitems of the test, both groups showed excellent reliability in four items. The mean Kappa value was higher in the K-MBI checklist group (.725) than in the original K-MBI group (.699). Conclusions : Both the newly developed K-MBI checklist and original K-MBI showed high consistency in their total scores. In the subitems, the newly developed K-MBI checklist provided higher consistency than the original K-MBI except for dressing subitems. Meanwhile, the K-MBI showed low consistency in personal hygiene and ambulation subitems.
