The Childhood Autism Rating Scale (CARS) is a popular behavior-observation instrument that was developed more than 34 years ago and has since been adopted in a wide variety of contexts for assessing the presence and severity of autism symptomatology in both children and adolescents. This investigation of the reliability of CARS scores involves meta-analysis and meta-regression of empirical data from reports of original research that made use of CARS between 1980 and 2012. Findings of good internal consistency (.896, 95 % CI .877-.913) and good interrater reliability (.796, 95 % CI .736-.844) support use of CARS at least in early-phase, exploratory research. Evidence of heterogeneity among literature data indicates that reliability is a property of CARS scores and is not intrinsic to the instrument itself. As the first of its kind pertaining to autism, this investigation provides guidance for reviews of other instruments' ratings.
儿童自闭症评定量表（CARS）是一种流行的行为观察工具，它是 34 多年前开发的，此后在各种环境中被采用，用于评估儿童和青少年自闭症症状的存在和严重程度。本研究通过对 1980 年至 2012 年间使用 CARS 的原始研究报告的实证数据进行荟萃分析和荟萃回归，对 CARS 评分的可靠性进行了研究。结果显示，CARS 具有良好的内部一致性（.896，95%置信区间：.877-.913）和良好的评分者间可靠性（.796，95%置信区间：.736-.844），这支持了在早期探索性研究中使用 CARS。文献数据的异质性表明，可靠性是 CARS 评分的一个属性，而不是仪器本身固有的属性。作为自闭症研究的首例，本研究为其他仪器评分的综述提供了指导。
