Abstract: Objective To establish Chinese norm of General Physical Activity Scale for children aged 3 to 6, and to explore its cut-off score for the norm, thus to provide a practical tool for clinical application.Methods From August 2020 to May 2021, a stratified cluster sampling approach was utilized to recruit 1 616 children aged 3 to 6 years from eight cities in six major administrative regions of China. The norm distribution and scores were analyzed, and its cut-off score was discussed.Results The scores of each dimension was significantly different among eight cities(F=10.964 - 117.766, P<0.001). The area under the receiver operating characteristic curve of the total score of the scale is 0.937(95%CI:0.916 - 0.957). The maximum Yuden Index(YI) was 0.74, and the corresponding total score was in the 17th percentile(P₁₇) in the norm, with the sensitivity of 0.871 and specificity of 0.864. When P₁₅ (76)and P₂₀(80)were taken as the threshold point, the corresponding YI was 0.69 and 0.72, respectively, and the sensitivity and specificity were both above 0.8.Conclusions The norm sample of this study is representative, and the cut-off score is appropriate, which can be popularized and applied in clinic practice.

摘要： 目的 建立3～6岁儿童基本运动能力评估量表的中国常模,探讨其常模界值,为临床运用提供一项实用的评估工具。方法 2020年8月—2021年5月,采取分层整群抽样的方法,使用3～6岁儿童基本运动能力评估量表获得全国六大行政区8个城市3～6岁儿童1 616例,统计分析量表全部6个维度的常模得分和界值点。结果 量表各维度得分比较,差异具有统计学意义(F=10.96～117.77,P＜0.001)。量表总分ROC曲线下面积为0.937,95%CI为0.916~0.957。最大约登指数(YI)=0.74,其对应的量表总分在常模中位于第17百分位(P₁₇),常模的灵敏度为0.871,特异度为0.864。当分别以P₁₅(76)和P₂₀(80)为界值点时,YI分别为0.69和0.72,灵敏度和特异度皆＞0.8。结论 本研究常模样本具有良好的代表性,制定的界值点适当,对评估3～6岁儿童基本运动能力具有很好的临床运用价值,可推广运用。
