Abstract

Purpose: Early language intervention is essential for children with indicators of language delay. Enhanced milieu teaching (EMT) is a naturalistic intervention that supports the language development of children with emerging language. We conducted a systematic review and meta-analysis of all qualifying single-case and group design studies that evaluate the experimental effects of EMT on child outcomes.

Method: We evaluated the risk of bias in the included studies and conducted a descriptive analysis of study quality, effect sizes, and demographics. We reviewed a total of 29 single-case and 17 group design studies in which 1,590 children participated.

Results: Out of 46 studies, 39 met the What Works Clearinghouse standards without reservations, showing low levels of risk of bias. The effects were comparable when EMT was implemented alone and when it was implemented with another intervention component, and EMT was more effective when implemented by caregivers than when implemented by therapists. Most studies did not report sufficient participant demographics.

Conclusions: The EMT research literature published thus far is of high study quality; the effects across studies are comparable; and the intervention has been studied via a wide range of delivery modalities, contexts, implementers, and samples. Future research could systematically examine the effects of EMT and explore these varying intervention delivery, implementer, and learner characteristics as moderators.

强化环境教学的系统回顾与元分析。
目的:早期语言干预对有语言迟缓指标的儿童至关重要。强化环境教学是一种支持新兴语言儿童语言发展的自然干预方法。我们对所有合格的单例和组设计研究进行了系统回顾和荟萃分析,以评估EMT对儿童结局的实验效果。方法:我们评估纳入研究的偏倚风险,并对研究质量、效应量和人口统计学进行描述性分析。我们总共回顾了29个单例研究和17个组设计研究,其中1590名儿童参与。结果:在46项研究中,39项毫无保留地达到了What Works Clearinghouse的标准,显示出低水平的偏倚风险。当EMT单独实施和与其他干预成分一起实施时,效果是相当的,并且由护理人员实施的EMT比由治疗师实施的EMT更有效。大多数研究没有报告足够的参与者人口统计数据。结论:目前已发表的EMT研究文献具有较高的研究质量;不同研究之间的影响具有可比性;并且通过广泛的交付方式、环境、实施者和样本对干预进行了研究。未来的研究可以系统地检查EMT的效果,并探索这些不同的干预交付、实施者和学习者特征作为调节因素。

期刊介绍: Mission: JSLHR publishes peer-reviewed research and other scholarly articles on the normal and disordered processes in speech, language, hearing, and related areas such as cognition, oral-motor function, and swallowing. The journal is an international outlet for both basic research on communication processes and clinical research pertaining to screening, diagnosis, and management of communication disorders as well as the etiologies and characteristics of these disorders. JSLHR seeks to advance evidence-based practice by disseminating the results of new studies as well as providing a forum for critical reviews and meta-analyses of previously published work. Scope: The broad field of communication sciences and disorders, including speech production and perception; anatomy and physiology of speech and voice; genetics, biomechanics, and other basic sciences pertaining to human communication; mastication and swallowing; speech disorders; voice disorders; development of speech, language, or hearing in children; normal language processes; language disorders; disorders of hearing and balance; psychoacoustics; and anatomy and physiology of hearing.
