The Childhood Autism Rating Scale (CARS) is an instrument for screening and diagnosis of autism. The present study was performed to assess the interrater reliability of a Swedish version of the CARS when used in a clinical setting. The procedure used mimicked a frequent form of consultation in neuropsychiatry and pediatric neurology. During a restricted time period, both an interview with the parents and observation of the child take place. Often this assessment is an important screening procedure and directs further investigation. CARS was used for rating autistic behavior by two investigators in 25 children. A variant of the weighted kappa statistic (correcting for chance and for degrees of disagreement) showed values between .53 and .75 (indicating fair to excellent agreement). Aspects of validity and reliability are discussed.
儿童自闭症评定量表（CARS）是一种用于自闭症筛查和诊断的工具。本研究旨在评估瑞典版CARS在临床环境中使用时的评分者间信度。所采用的程序模拟了神经精神病学和儿科神经学中常见的会诊形式。在限定的时间段内，既要与家长进行访谈，又要对儿童进行观察。通常，这种评估是一项重要的筛查程序，并指导进一步的调查。两位研究者使用CARS对25名儿童的自闭症行为进行评分。加权kappa统计量的一个变体（对机遇和不一致程度进行校正）显示的值在0.53至0.75之间（表明一致性为中等至优秀）。文中还讨论了效度和信度方面的问题。
