Purpose There has been increased interest in using telepractice for involving more diverse children in research and clinical services, as well as when in-person assessment is challenging, such as during COVID-19. Little is known, however, about the feasibility, reliability, and validity of language samples when conducted via telepractice. Method Child language samples from parent-child play were recorded either in person in the laboratory or via video chat at home, using parents' preferred commercially available software on their own device. Samples were transcribed and analyzed using Systematic Analysis of Language Transcripts software. Analyses compared measures between-subjects for 46 dyads who completed video chat language samples versus 16 who completed in-person samples; within-subjects analyses were conducted for a subset of 13 dyads who completed both types. Groups did not differ significantly on child age, sex, or socioeconomic status. Results The number of usable samples and percent of utterances with intelligible audio signal did not differ significantly for in-person versus video chat language samples. Child speech and language characteristics (including mean length of utterance, type-token ratio, number of different words, grammatical errors/omissions, and child speech intelligibility) did not differ significantly between in-person and video chat methods. This was the case for between-group analyses and within-child comparisons. Furthermore, transcription reliability (conducted on a subset of samples) was high and did not differ between in-person and video chat methods. Conclusions This study demonstrates that child language samples collected via video chat are largely comparable to in-person samples in terms of key speech and language measures. Best practices for maximizing data quality for using video chat language samples are provided.
人们越来越感兴趣地使用远程实践来让更多不同背景的儿童参与研究和临床服务,以及在面对面评估具有挑战性的情况下,例如在 COVID-19 期间。然而,对于通过远程实践进行语言样本的可行性、可靠性和有效性知之甚少。
使用父母首选的商业可用软件,在实验室中亲自或在家中通过视频聊天录制亲子游戏中的儿童语言样本。使用语言转录系统分析软件对样本进行转录和分析。分析比较了 46 对通过视频聊天完成语言样本的亲子组和 16 对通过面对面完成语言样本的亲子组之间的组间测量值;对于 13 对完成两种类型样本的亲子组进行了组内分析。
面对面与视频聊天语言样本的可用样本数量和可理解音频信号的话语百分比没有显著差异。儿童言语和语言特征(包括平均话语长度、类型-令牌比、不同单词数量、语法错误/遗漏和儿童言语清晰度)在面对面和视频聊天方法之间没有显著差异。无论是组间分析还是儿童内比较都是如此。此外,转录可靠性(在部分样本上进行)很高,并且在面对面和视频聊天方法之间没有差异。
这项研究表明,通过视频聊天收集的儿童语言样本在关键言语和语言测量方面与面对面样本基本可比。提供了使用视频聊天语言样本最大化数据质量的最佳实践。
