대동작 기능 평가도구(GMFM)의 Rasch분석

Application of Rasch Analysis to the Gross Motor Function Measure: A Preliminary Study

The purpose of this study was to validate the Korean version of the Gross Motor Function Measure(GMFM) using Rasch analysis. The data was obtained from the assessments of 59 children with cerebral palsy in Korea and were applied to Rasch’s rating scale model to estimate the difficulty and good-ness-of-fit of each item. Rasch modeling helped us to identify 76 items from the original 88-item GMFM that form an unidimensional hierarchical scale to rearrange 76 items in order of difficulty. Reliability coefficients of the 88-item and 76-item GMFM were .99 and .99, respectively. In this preliminary report, the Korean version of GMFM seems to have significant validity and reliability. These results may be useful in assessment of gross motor function in children with cerebral palsy.
