摘要
目的:尽管在早期干预中监测表达性语言的变化非常重要,但现有的语言评估方法往往成本高昂、耗时长,而且捕捉到的自闭症儿童的变化有限。因此,语言环境分析(Language ENvironmental Analysis,LENA)系统作为一种自动化方法受到了广泛关注,该方法有望以更高效、更具成本效益的方式捕捉语言发展的细微变化。然而,目前对 LENA 系统在非结构化环境中跟踪早期干预反应的实用性评估还很有限:本研究的目的是在先前研究的基础上,通过评估 LENA 系统在明确界定的临床样本中的使用情况,这些临床样本来自一项随机对照试验(RCT),即 "关键反应治疗"(PRT),该试验通过标准化和人工编码的测量方法证明了语言表达能力的提高:结果:对自动衍生的 LENA 指标(即儿童发声、会话转折)的研究表明,这些指标与标准化语言评估(即 Mullen 表达性语言分量表、MacArthur Bates 沟通能力发展量表、Vineland-II 表达性语言分量表)无显著关联。此外,与延迟治疗组相比,从基线到干预后,参加 PRT 的儿童在家庭环境中收集的全天自然 LENA 录音中,发声或会话转向的数量并没有明显增加:讨论了自然语言取样和早期干预中表达性语言测量的意义和未来方向。
Using Language Environment Analysis System (LENA) in Natural Settings to Characterize Outcomes of Pivotal Response Treatment.
Purpose: Despite the importance of monitoring changes in expressive language in early intervention, existing approaches to language assessment are often costly, time-intensive, and capture limited variability in autistic children. The Language ENvironmental Analysis (LENA) system has thus received considerable attention as an automated approach that may hold promise for capturing fine-grained changes in language development in a more efficient and cost-effective manner. However, evaluations of the utility of the LENA system for tracking response to early intervention in unstructured contexts are currently limited.
Methods: This study aimed to build on prior research through evaluating the use of LENA in the context of a well-defined clinical sample from a randomized controlled trial (RCT) of Pivotal Response Treatment (PRT) that demonstrated expressive language gains across standardized and manually-coded measures.
Results: Exploration of automatically-derived LENA metrics (i.e., child vocalizations, conversational turns) revealed no significant association with standardized language assessments (i.e., Mullen expressive language subscale, MacArthur Bates Communicative Development Inventory, Vineland-II expressive language subscale). Furthermore, relative to the delayed treatment group, children participating in PRT did not show significantly greater improvement in the number of vocalizations or conversational turns during naturalistic, daylong LENA recordings collected in home settings from baseline to post-intervention.
Conclusion: Implications and future directions for natural language sampling and the measurement of expressive language in early intervention are discussed.
期刊介绍:
The Journal of Autism and Developmental Disorders seeks to advance theoretical and applied research as well as examine and evaluate clinical diagnoses and treatments for autism and related disabilities. JADD encourages research submissions on the causes of ASDs and related disorders, including genetic, immunological, and environmental factors; diagnosis and assessment tools (e.g., for early detection as well as behavioral and communications characteristics); and prevention and treatment options. Sample topics include: Social responsiveness in young children with autism Advances in diagnosing and reporting autism Omega-3 fatty acids to treat autism symptoms Parental and child adherence to behavioral and medical treatments for autism Increasing independent task completion by students with autism spectrum disorder Does laughter differ in children with autism? Predicting ASD diagnosis and social impairment in younger siblings of children with autism The effects of psychotropic and nonpsychotropic medication with adolescents and adults with ASD Increasing independence for individuals with ASDs Group interventions to promote social skills in school-aged children with ASDs Standard diagnostic measures for ASDs Substance abuse in adults with autism Differentiating between ADHD and autism symptoms Social competence and social skills training and interventions for children with ASDs Therapeutic horseback riding and social functioning in children with autism Authors and readers of the Journal of Autism and Developmental Disorders include sch olars, researchers, professionals, policy makers, and graduate students from a broad range of cross-disciplines, including developmental, clinical child, and school psychology; pediatrics; psychiatry; education; social work and counseling; speech, communication, and physical therapy; medicine and neuroscience; and public health.
