表达性语言和沟通是自闭症谱系障碍（ASD）个体干预的关键目标之一，自然语言样本为他们的评估提供了最佳方法。目前，还没有收集这种样本的协议，涵盖广泛的年龄或语言能力，特别是对儿童/青少年谁有非常有限的口语。我们介绍了一种新的协议，收集语言样本，引出语言样本进行分析（艾尔莎），并从它绕过了耗时的转录需要一种新的方法来获得口头交际能力的基本措施。研究1介绍了ELSA-青少年（ELSA-A），设计用于患有ASD的最低限度和低语言的大龄儿童/青少年。该协议成功地从事，并引起了广泛的年龄范围内（6;6-19;7）与样本平均20-25分钟的演讲46名参与者。收集的样本被分割成扬声器的话语（考官和参与者）使用实时编码，因为一个是听录音和两个措施得出：频率的话语和每分钟的会话回合。这些措施被证明是可靠和有效的。对于研究2，艾尔莎适用于年龄较小的儿童（艾尔莎-幼儿[ELSA-T]），样本平均29分钟来自19名患有ASD的幼儿（2岁;8-4岁;10岁）。同样，来自ELSA-T的话语频率和会话回合的措施被证明具有很强的心理测量特性。在研究3中，我们发现ELSA-A和ELSA-T在17名ASD儿童（年龄：4岁;0-6岁;8岁）的诱发语言方面是等效的，这表明它们适用于对表达性语言进行可靠的客观评估，可用于跟踪能力随时间的变化。我们引入了一种用于收集表达性语言样本的新协议，即艾尔莎，该协议可用于广泛的年龄范围，从幼儿（ELSA-T）到语言能力最低或较低的患有自闭症谱系障碍的老年青少年（ELSA-A）。语言和沟通的措施，从他们，话语的频率，每分钟的会话次数，使用实时编码的方法，可以用来描述能力和图表的变化在干预研究。我们介绍了一种用于收集表达性语言样本的新协议，艾尔莎，可以用于广泛的年龄范围，从幼儿（ELSA-T）到患有自闭症谱系障碍的年龄较大的青少年（ELSA-A），他们具有最小或低的语言能力。语言和沟通的措施，从他们，话语频率和每分钟的会话回合，使用实时编码方法，可以用来描述能力和图表的变化在干预研究。
Expressive language and communication are among the key targets of interventions for individuals with autism spectrum disorder (ASD), and natural language samples provide an optimal approach for their assessment. Currently, there are no protocols for collecting such samples that cover a wide range of ages or language abilities, particularly for children/adolescents who have very limited spoken language. We introduce a new protocol for collecting language samples, eliciting language samples for analysis (ELSA), and a novel approach for deriving basic measures of verbal communicative competence from it that bypasses the need for time-consuming transcription. Study 1 presents ELSA-adolescents (ELSA-A), designed for minimally and low-verbal older children/adolescents with ASD. The protocol successfully engaged and elicited speech from 46 participants across a wide range of ages (6;6-19;7) with samples averaging 20-25 min. The collected samples were segmented into speaker utterances (examiner and participant) using real-time coding as one is listening to the audio recording and two measures were derived: frequency of utterances and conversational turns per minute. These measures were shown to be reliable and valid. For Study 2, ELSA was adapted for younger children (ELSA-Toddler [ELSA-T]) with samples averaging 29 min from 19 toddlers (2;8-4;10 years) with ASD. Again, measures of frequency of utterances and conversational turns derived from ELSA-T were shown to have strong psychometric properties. In Study 3, we found that ELSA-A and ELSA-T were equivalent in eliciting language from 17 children with ASD (ages: 4;0-6;8), demonstrating their suitability for deriving robust objective assessments of expressive language that could be used to track change in ability over time. We introduce a new protocol for collecting expressive language samples, ELSA, that can be used with a wide age range, from toddlers (ELSA-T) to older adolescents (ELSA-A) with ASD who have minimal or low-verbal abilities. The measures of language and communication derived from them, frequency of utterances, and conversational turns per minute, using real-time coding methods, can be used to characterize ability and chart change in intervention research. Lay Summary We introduce a new protocol for collecting expressive language samples, ELSA, that can be used with a wide age range, from toddlers (ELSA-T) to older adolescents (ELSA-A) with autism spectrum disorder who have minimal or low-verbal abilities. The measures of language and communication derived from them, frequency of utterances and conversational turns per minute, using real-time coding methods, can be used to characterize ability and chart change in intervention research.
