Purpose The Access to Literacy Assessment System-Phonological Awareness (ATLAS-PA) was developed for use with children with speech and/or language impairment. The subtests (Rhyming, Blending, and Segmenting) are appropriate for children who are 3-7 years of age. ATLAS-PA is composed entirely of receptive items, incorporates individualized levels of instruction, and is adaptive in nature. Method To establish the construct validity of ATLAS-PA, we collected data from children with typical development (n = 938) and those who have speech and/or language impairment (n = 227). Results Rasch analyses indicated that items fit well together and formed a unidimensional construct of phonological awareness. Differential item functioning was minimal between the two groups of children, and scores on ATLAS-PA were moderately to strongly related to other measures of phonological awareness. Information about item functioning was used to create an adaptive version of ATLAS-PA. Conclusions Findings suggest that ATLAS-PA is a valid measure of phonological awareness that can be used with children with typical development and with speech and/or language impairment. Its adaptive format minimizes testing time and provides opportunities for monitoring progress in preschool and early elementary classrooms.

语音意识的扫盲评估系统的使用：一种适用于言语和/或语言障碍儿童的语音意识自适应方法。

目的旨在为有言语和/或语言障碍的儿童使用通识能力评估系统-语音意识（ATLAS-PA）。子测验（押韵，混合和分段）适用于3-7岁的孩子。ATLAS-PA完全由接受项组成，并结合了个性化的指导水平，并且具有适应性。方法为了确定ATLAS-PA的结构效度，我们从典型发育儿童（n = 938）和有语音和/或语言障碍的儿童（n = 227）中收集数据。结果Rasch分析表明，项目很好地契合在一起，并形成了语音意识的一维结构。两组儿童之间的差异项功能最小，ATLAS-PA的分数与其他语音意识测量指标之间存在中等程度的相关性。有关项目功能的信息用于创建自适应版本的ATLAS-PA。结论结论表明，ATLAS-PA是一种有效的语音意识测验，可用于具有典型发育以及语音和/或语言障碍的儿童。其自适应格式最大程度地减少了测试时间，并提供了监视学前班和早期小学教室进度的机会。补充材料https://doi.org/10.23641/asha.12931691。结论结论表明，ATLAS-PA是一种有效的语音意识测验，可用于具有典型发育以及语音和/或语言障碍的儿童。其自适应格式最大程度地减少了测试时间，并提供了监视学前班和早期小学教室进度的机会。补充材料https://doi.org/10.23641/asha.12931691。结论结论表明，ATLAS-PA是一种有效的语音意识测验，可用于具有典型发育以及语音和/或语言障碍的儿童。其自适应格式最大程度地减少了测试时间，并提供了监视学前班和早期小学教室进度的机会。补充材料https://doi.org/10.23641/asha.12931691。
