To assess the reliability and validity of the Chinese version of the Selective Control Assessment of the Lower Extremity (SCALE) in children with spastic cerebral palsy (CP).
Forty-five children with spastic CP (mean age 7.29 years, SD 2.87 years, rang 4-16 years) were recruited. Internal consistency was measured using Cronbach's α, while test-retest and inter-rater reliability were evaluated using intra-class correlation coefficients (ICC). Construct validity was established through correlation and confirmatory factor analyses. Discriminative validity was assessed by comparing SCALE scores across varying GMFCS levels.
The Chinese version of SCALE demonstrates high internal consistency (Cronbach's = 0.91) and good reliability with ICCs exceeding 0.76 for test-retest and inter-rater assessments. It shows significant correlations with GMFCS ( = -0.76, < 0.001) and Fugl-Meyer scales ( = 0.79, < 0.001), confirming its validity. Confirmatory factor analysis supports a well-fitting model ( /df = 1.58, RMSEA = 0.08, SRMR <0.001, GFI = 0.98, AGFI = 0.90, CFI = 0.99, TLI = 0.98), with the latent variable's AVE at 0.59 and CR at 0.88. Discriminative validity is evident in significant differences across GMFCS levels ( < 0.001), notably between levels I and II, I and III, and I and IV ( < 0.05).
The Chinese version of SCALE shows good reliability and validity for assessing lower limb selective movement control in children with spastic cerebral palsy in China.

评估中文版下肢选择性控制评估量表（SCALE）在痉挛型脑瘫（CP）儿童中的信度和效度。
招募了45名痉挛型CP儿童（平均年龄7.29岁，标准差2.87岁，年龄范围4 - 16岁）。使用Cronbach's α系数测量内部一致性，使用组内相关系数（ICC）评估重测信度和评分者间信度。通过相关性分析和验证性因素分析建立结构效度。通过比较不同GMFCS水平的SCALE评分评估区分效度。
中文版SCALE显示出高内部一致性（Cronbach's α = 0.91），重测和评分者间评估的ICC超过0.76，具有良好的信度。它与GMFCS（r = -0.76，p < 0.001）和Fugl - Meyer量表（r = 0.79，p < 0.001）显示出显著相关性，证实了其效度。验证性因素分析支持一个拟合良好的模型（χ²/df = 1.58，RMSEA = 0.08，SRMR < 0.001，GFI = 0.98，AGFI = 0.90，CFI = 0.99, TLI = 0.98），潜在变量的AVE为0.59，CR为0.88。在不同GMFCS水平之间存在显著差异（p < 0.001），特别是在I级和II级、I级和III级以及I级和IV级之间（p < 0.05），区分效度明显。
