Abstract：
OBJECTIVE: The aim of this study was to examine the validity and reliability of the Sitting Assessment Scale (SAS) in individuals with cerebral palsy (CP).
METHODS: The study included 34 individuals with a diagnosis of spastic CP. Individuals were evaluated with the Gross Motor Function Classification System and the Manual Ability Classification System. SAS and Trunk Control Measurement Scale (TCMS) were applied to the participants. The intraclass correlation coefficient (ICC) was calculated to determine the intraobserver and interobserver reliability of the scale scored by three different physiotherapists at two different time intervals. Internal consistency was calculated with Cronbach\'s ⍺ coefficient. The fit between SAS and TCMS for criterion-dependent validity was evaluated using Pearson Correlation Analysis.
RESULTS: According to the GMFCS level, 79.41% of the children were mildly (Level I-II), 14.71% were moderately affected (level III), and 5.88% were severely affected (level IV). Intra > observer and interobserver reliability values of SAS were extremely high (ICCinterrater > 0.923, ICCintrarater > 0.930). It was observed that the internal consistency of SAS had high values (Cronbach ⍺test > 0.822, Cronbach ⍺retest > 0.804). For the criterion-dependent reliability; positive medium correlations found between SAS with Total TCMS Static Sitting Balance (r = 0.579, p < 0.001), with TCMS Selective Movement Control (r = 0.597, p < 0.001), with TCMS Dynamic Reaching (r = 0.609, p < 0.001), and with TCMS Total (r = 0.619, p < 0.001).
CONCLUSIONS: SAS was found to have high validity and reliability in children with CP. In addition, the test-retest reliability of the scale was also high. SAS is a practical tool that can be used to assess sitting balance in children with CP.

摘要：
目的：这项研究的目的是检查坐姿评估量表（SAS）在脑瘫（CP）患者中的有效性和可靠性。
方法：该研究包括34名诊断为痉挛型CP的个体。使用粗大运动功能分类系统和手动能力分类系统对个人进行评估。对参与者应用SAS和干线控制测量量表(TCMS)。计算组内相关系数（ICC）以确定三个不同物理治疗师在两个不同时间间隔评分的量表的观察者内和观察者间可靠性。内部一致性是用Cronbach的系数计算的。使用Pearson相关分析评估SAS和TCMS对标准依赖效度的拟合度。
结果：根据GMFCS级别，79.41％的儿童轻度（I-II级），14.71%受到中度影响(三级),5.88%受到严重影响(Ⅳ级)。SAS的内部>观察者和观察者间可靠性值极高（ICCinterrater>0.923，ICCintrarater>0.930）。观察到SAS的内部一致性具有较高的值(Cronbach测试>0.822,Cronbach测试>0.804)。对于与标准相关的可靠性；SAS与总TCMS静态坐姿平衡之间的正中等相关性(r=0.579，p<0.001)，使用TCMS选择性运动控制(r=0.597，p<0.001)，TCMS动态到达(r=0.609，p<0.001)，和TCMS总计（r=0.619，p<0.001）。
结论：SAS在CP患儿中具有较高的效度和信度。此外,量表的重测信度也很高。SAS是一种实用的工具，可用于评估CP儿童的坐位平衡。
