The aims of this paper are to present the Autism Behaviour Coding System (ABCS), a novel, video-based observational instrument for assessing core autism symptoms during intensive early interventions in autism spectrum disorder (ASD), to provide preliminary data on its psychometric characteristics and to discuss its clinical utility. Video recordings of child-therapist interactions during the 'Frühintervention bei autistischen Störungen' (FIAS) were coded by treatment-independent raters who were blind with respect to the temporal order of the sequences. We assessed inter-rater reliability using intra-class correlations (ICCs). Mean ICCs ranged from 0.85 to 0.90. We analysed the sensitivity of the ABCS to change by comparing the change in ABCS scores with the change in a validated external measure of level of functioning (Developmental Disorder-Child-Global Assessment of functioning Scale, DD-C-GAS) in a sample of 15 children who received intensive treatment. Both the ABCS and DD-C-GAS indicated that the intervention improved symptoms. The ABCS has promise as a research instrument and has good to excellent inter-rater agreement and sensitivity to intervention-related changes. This pilot study suggests that the ABCS may be useful as an objective method of assessing the proximal effects of therapy in young children with ASD.
本文旨在介绍自闭症行为编码系统（ABCS），这是一种新颖的基于视频的观察工具，用于评估自闭症谱系障碍（ASD）强化早期干预期间的核心自闭症症状，提供其心理测量特征的初步数据，并讨论其临床实用性。在“自闭症早期干预”（FIAS）期间，治疗师与儿童的互动视频由独立于治疗的评估者进行编码，评估者对序列的时间顺序是盲目的。我们使用组内相关系数（ICC）评估了评分者间的可靠性。平均 ICC 范围为 0.85 到 0.90。我们通过比较 ABCS 评分的变化与经过验证的外部功能水平衡量标准（发育障碍-儿童-功能总体评估量表，DD-C-GAS）的变化，在接受强化治疗的 15 名儿童的样本中分析了 ABCS 对变化的敏感性。ABCS 和 DD-C-GAS 都表明干预改善了症状。ABCS 有望成为一种研究工具，具有良好到极好的评分者间一致性和对干预相关变化的敏感性。这项初步研究表明，ABCS 可能是一种有用的方法，可作为评估 ASD 幼儿治疗近端效果的客观方法。
