The purpose of this study was to develop a Japanese version of the Functional Mobility Scale (FMS), and examine the criterion validity and intra-rater reliability of the FMS in Japan.
The translation of the FMS was performed according to international standards for the translation of measurements. For criterion validity, 111 children with cerebral palsy (mean age; 12year 1mo±3year 7mo; range 5-18) were rated the Japanese version of the FMS and Gross Motor Function Classification System (GMFCS). For intra-rater reliability, the Japanese version of the FMS was rated twice by 24 parents of children with cerebral palsy by interview and/or telephone with a one- to two-week interval between assessments.
The criterion validity was confirmed with a strong correlation between GMFCS level and FMS scores (r=-0.71 to -0.75). For intra-rater reliability, there was a substantial to excellent level of agreement (kappa=0.72-0.87).
The study provides evidence of the criterion validity and intra-rater reliability of the Japanese version of the FMS as a measurement of mobility in children with cerebral palsy.
本研究旨在开发功能性移动量表（FMS）的日文版，并检验其在日本的效标效度和内部评分者信度。
根据测量学的国际标准进行 FMS 的翻译。为了评估效标效度，对 111 名脑瘫儿童（平均年龄：12 岁 1 个月±3 岁 7 个月；范围 5-18 岁）进行了日文版 FMS 和粗大运动功能分类系统（GMFCS）的评定。为了评估内部评分者信度，由 24 名脑瘫儿童的家长通过访谈和/或电话对日文版 FMS 进行了两次评定，两次评定之间的间隔为 1-2 周。
GMFCS 水平与 FMS 评分之间存在很强的相关性，证实了效标效度（r=-0.71 至-0.75）。对于内部评分者信度，存在实质性到极好的一致性（kappa=0.72-0.87）。
本研究提供了证据，证明日文版 FMS 作为脑瘫儿童移动能力的测量工具具有效标效度和内部评分者信度。
