The PEDI-CAT (ASD) is used to assess functioning of children and youth on the autism spectrum; however, current psychometric evidence is limited. This study aimed to explore the reliability, validity and acceptability of the PEDI-CAT (ASD) using a large Australian sample.
Caregivers of 134 children and youth on the spectrum participated in clinical assessments involving the administration of the PEDI-CAT (ASD), Vineland-3, PEDI-CAT (Original) and a feedback instrument. The PEDI-CAT (ASD) content was compared to the ICF Core Sets for ASD to summarize areas of functioning assessed and relevance to autism.
The PEDI-CAT (ASD) demonstrated good to excellent internal consistency and test-re-test reliability. Parallel forms reliability with the PEDI-CAT (Original) included significant correlations (good to excellent), however, t-tests showed significantly higher Social/Cognitive scores for the ASD version. Convergent validity results demonstrated that most PEDI-CAT (ASD) and Vineland-3 core domains were significantly correlated (poor to good). Content analysis revealed that the PEDI-CAT (ASD) covered less than half of the ICF Core Sets for ASD (mostly Activities and Participation codes). Just over half the codes assigned to the PEDI-CAT (ASD) were represented in the ICF Core Sets for ASD. Feedback on the acceptability of the measure was mixed, but overall was it was considered user-friendly and efficient.
The PEDI-CAT (ASD) had adequate psychometric properties and acceptability as a measure of Activities and Participation codes. However, it lacks comprehensiveness and relevance when compared to the ICF Core Sets for ASD and has the potential to overestimate functioning.
儿童自闭症功能评定量表（PEDI-CAT，自闭症版）用于评估自闭症谱系中的儿童和青少年的功能；然而，目前的心理测量证据有限。本研究旨在使用大量澳大利亚样本探讨PEDI-CAT（自闭症版）的信度、效度和可接受性。
134名自闭症谱系儿童和青少年的照料者参与了临床评估，评估内容包括PEDI-CAT（自闭症版）、文兰适应行为量表第三版（Vineland-3）、PEDI-CAT（原版）以及一份反馈工具的施测。将PEDI-CAT（自闭症版）的内容与自闭症的国际功能、残疾和健康分类核心集（ICF核心集）进行比较，以总结所评估的功能领域以及与自闭症的相关性。
PEDI-CAT（自闭症版）表现出良好至极优的内部一致性和重测信度。与PEDI-CAT（原版）的平行效度包括显著相关性（良好至极优），然而，t检验显示自闭症版的社会/认知得分显著更高。聚合效度结果表明，大多数PEDI-CAT（自闭症版）和Vineland-3核心领域显著相关（差至良好）。内容分析显示，PEDI-CAT（自闭症版）涵盖不到自闭症ICF核心集的一半（主要是活动和参与代码）。分配给PEDI-CAT（自闭症版）的代码中，略多于一半出现在自闭症ICF核心集中。关于该测量方法可接受性的反馈不一，但总体而言，它被认为用户友好且高效。
PEDI-CAT（自闭症版）作为活动和参与代码的测量工具具有足够的心理测量特性和可接受性。然而，与自闭症ICF核心集相比，它缺乏全面性和相关性，并且有可能高估功能。
