The gross motor function measurement is considered as the gold standard for the motor assessment of children with cerebral palsy. The aim was to carry out the cross-cultural adaptation and investigate psychometric properties.
A total of 150 children with cerebral palsy aged 2-16 (mean 8.82 ± 3.78 years; 54.7% male) included. The Gross Motor Function Measurement was adapted into Turkish. Two physiotherapies independently administered the gross motor function measurement. Internal consistency and intra/inter-rater reliability were assessed using Cronbach's alpha, intraclass-correlation-coefficient. Standard-error-of-measurement, minimal-detectible-change calculated. The Bland-Altman method was applied to estimate the measurement bias in reliability analysis. Construct validity assessed with Spearman's correlation coefficient between the gross motor function measurement and the gross motor function classification system, pediatric-evaluation-of-disability-inventory-mobility; confirmatory-factor-analysis was carried.
Internal-consistency (α: 0.997-1.00); reliability indices were excellent for total scale (intraclass-correlation-coefficient for intra-rater reliability 0.994-0.999, inter-rater reliability 0.997-0.999) and for each sub-dimension and total score. Standard-error-of-measurement was ranging 1.044-1.677, minimal-detectible-change was 2.435-5.520. Construct validity was supported by strong to excellent negative significant correlations ( < 0.05).
粗大运动功能测量被认为是评估脑瘫儿童运动功能的金标准。目的是进行跨文化改编并调查心理测量特性。
共纳入150名2至16岁的脑瘫儿童（平均8.82±3.78岁；54.7%为男性）。将粗大运动功能测量改编为土耳其语。两名物理治疗师独立进行粗大运动功能测量。使用克朗巴哈α系数、组内相关系数评估内部一致性和评分者内/间信度。计算测量标准误差、最小可检测变化。在信度分析中应用布兰德-奥特曼方法估计测量偏差。通过粗大运动功能测量与粗大运动功能分类系统、儿童残疾评估量表-移动性之间的斯皮尔曼相关系数评估结构效度；进行验证性因素分析。
内部一致性（α：0.997 - 1.00）；总量表及各子维度和总分的信度指标均极佳（评分者内信度的组内相关系数为0.994 - 0.999，评分者间信度为0.997 - 0.999）。测量标准误差范围为1.044 - 1.677，最小可检测变化为2.435 - 5.520。结构效度得到强至极佳的负显著相关性（<0.05）支持。
