OBJECTIVES
To assess "alternate forms" reliability and inter-rater reliability of Gross Motor Function Classification System (GMFCS) scores.
METHODS
Fifty randomly selected children with cerebral palsy were divided into two groups: (1) GMFCS score assigned during gait assessment ("GMFCS previously assigned") and (2) no GMFCS score assigned. Using database information, two physiotherapists independently determined GMFCS scores for 25 children from the "previously assigned" group, and 25 from the "no score assigned" group. Therapists compared their recently assigned scores for the "previously assigned" group, discussing discrepancies until attaining agreement. This group's consensus scores were compared to GMFCS scores assigned at time of actual assessment to calculate "alternate forms" reliability.
RESULTS
Between-therapist agreements were kappa = 0.84 for "GMFCS previously assigned" group and 0.95 for "no GMFCS assigned" group. Kappa agreement between direct assessment and retrospectively assigned scores for the "GMFCS previously assigned" group was 0.79.
CONCLUSIONS
Retrospective GMFCS scores can be reliably assigned.
目的
评估粗大运动功能分类系统（GMFCS）评分的“交替形式”信度和评分者间信度。
方法
随机选取50名脑瘫儿童，分为两组：（1）步态评估时分配的GMFCS评分（“先前分配的GMFCS”）；（2）未分配GMFCS评分。利用数据库信息，两名物理治疗师分别为“先前分配”组的25名儿童和“未评分”组的25名儿童确定GMFCS评分。治疗师比较他们最近为“先前分配”组给出的评分，讨论差异直至达成一致。将该组的共识评分与实际评估时分配的GMFCS评分进行比较，以计算“交替形式”信度。
结果
“先前分配的GMFCS”组治疗师间的一致性kappa值为0.84，“未分配GMFCS”组为0.95。“先前分配的GMFCS”组直接评估与回顾性分配评分之间的kappa一致性为0.79。
结论
回顾性GMFCS评分可以可靠地分配。
