The Pediatric Evaluation of Disability Inventory-Computer Adaptive Test is an alternative method for describing the adaptive function of children and youth with disabilities using a computer-administered assessment. This study evaluated the performance of the Pediatric Evaluation of Disability Inventory-Computer Adaptive Test with a national sample of children and youth with autism spectrum disorders aged 3-21 years. Parents (n = 365) completed an online survey that included demographics, the Social Communication Questionnaire, and the Pediatric Evaluation of Disability Inventory-Computer Adaptive Test Social/Cognitive, Daily Activities, and Responsibility domains. Item response theory analysis confirmed items in each domain fit a unidimensional model and few items misfit. A large number of items in the Social/Cognitive domain showed differential item functioning, indicating a unique order of item difficulty in this population in this domain. Differences in item difficulty estimates were addressed through a parameter linking (equating) process. Simulations supported the accuracy and precision of the Computer Adaptive Test. Results suggest that the Pediatric Evaluation of Disability Inventory-Computer Adaptive Test, as modified for autism spectrum disorder, is an efficient and sound assessment for this population.
《儿童残疾评定量表-计算机自适应测试》是一种通过计算机管理的评估方法来描述残疾儿童和青少年适应功能的替代方法。本研究使用全国范围内3至21岁自闭症谱系障碍儿童和青少年样本，对《儿童残疾评定量表-计算机自适应测试》的性能进行了评估。365名家长完成了一项在线调查，该调查包括人口统计学信息、《社会沟通问卷》以及《儿童残疾评定量表-计算机自适应测试》的社会/认知、日常活动和责任领域。项目反应理论分析证实，每个领域的项目均符合单维模型，且极少项目不匹配。社会/认知领域的大量项目显示出项目功能差异，表明该领域该人群中项目难度的独特顺序。通过参数链接（等值）过程解决了项目难度估计的差异。模拟结果支持了计算机自适应测试的准确性和精确性。结果表明，针对自闭症谱系障碍进行修改后的《儿童残疾评定量表-计算机自适应测试》，对该人群而言是一种有效且可靠的评估工具。
