摘要
目的采用Rasch分析法确定粗大运动功能测试量表(GMFM)66项在0-3岁脑性瘫痪(脑瘫)患儿粗大运动功能评估中的信度和效度。方法对171例0-3岁脑瘫患儿用GMFM 88项量表进行评估,获得有效样本298个,采用Rasch统计方法筛选出GMFM 73项,同时获得各样本的GMFM 73项分值,通过GMFM 73项与GMFM 66分值之间以及改变分值之间进行相关性分析来判断GMFM 66项在0-3岁脑瘫患儿粗大运动评估中的信度和效度。结果GMFM 73项分值与GMFM 66分值高度相关(r=0．9848,P<0．001),不同月龄和类型的脑瘫患儿GMFM 73项分值与GMFM 66分值之间也呈高度相关(r=0．9484-0．9958,P<0．001);在间隔(3．6±1．5)个月后, GMFM 73项的平均改变分值为4．37±4．51,GMFM 66的平均改变分值为4．19±4．29,两者改变分值之间呈高度相关(r=0．8700,P<0．001),GMFM 66的精确度和效应尺度略高于GMFM 73。结论GMFM 66项在0-3岁脑瘫患儿粗大运动功能评估中具有良好的信度和效度。
Objective To examine the reliability and validity of the 66-item version on the gross motor function measure （GMFM-66） to assess the gross motor functions of children below 3 years old with cerebral palsy. Methods 298 valid samples were obtained from 171 children with cerebral palsy （male 126, female 45 with mean age 19 months, age range 3-36 months） measured with GMFM-88, Then a 73- item version of GMFM （GMFM-73） special for these children was obtained by Rasch analysis, Both GMFM-66 and GMFM-73 scores of to each sample were obtained. The reliability and validity of GMFM- 66 were evaluated through analyzing the correlation between the scores and between the changed scores of these two GMFM versions. The relative precision of GMFM-73 versus GMFM-66 was also analyzed, Results Significant correlations were found between the scores and between the changed scores of these two versions of GMFM, A 14 % less gain in relative precision was achieved when using GMFM-73 versus GMFM-66. Conclusion Results indicated that the GMFM-66 had good reliability and validity in assessing the gross motor functions of children below 3 years old with cerebral palsy.
