Equating activities of daily living outcome measures: the Functional Independence Measure and the Korean version of Modified Barthel Index.

The Rasch equating method successfully created three crosswalks between the FIM motor items and K-MBI, with the equated test items demonstrating good psychometrics. The crosswalks would address the incomparable scoring systems between the FIM motor items and K-MBI. Implications for Rehabilitation The three crosswalk tables (scoring tables) would allow clinicians to compare or translate a patient's motor scores between the FIM and K-MBI. The crosswalk tables would allow health-care administrators to track patients' functional status across various rehabilitation facilities that exclusively use the FIM or K-MBI.
