Abstract
Background: The Pediatric Balance Scale (PBS) was developed to assess of balance ability in children with balance problem. The PBS was translated into Korean and its reliability had been studied. However, it had need to be verified using psychometric characteristics including item fit and rating scale. Objects: The purpose of this study was to investigate the item fit, item difficulty, and rating scale of the Korean version of PBS using Rasch analysis. Methods: In total, 40 children with cerebral palsy (CP) (boy=17, girl=23) who were diagnosed with level 1 or 2 according to the Gross Motor Function Classification System participated in this study. The PBS was performed, and was verified regarding the item fit, item difficulty, rating scale, and separation index and reliability using Rasch analysis. Results: In this study, the 'transfer', and 'turning to look behind left and right shoulders while standing still' item showed misfit statistics. in total 40 children with CP. Also, 'transfer', 'standing unsupported with feet together' and 'standing with one foot in front' items showed misfit statistics in diplegia CP group. Regardless of the classification of CP, the most difficult item was 'standing on one foot', whereas the easiest item was 'sitting with back unsupported and feet supported on the floor'. The 4 rating scale categories of PBS were acceptable with all criteria. Both item and person separation indices and reliability showed acceptable values. Conclusion: The PBS has been proven reliable, valid and is an appropriate tool, but it needs to modify the items of PBS according to CP classification.
