Abstract

Purpose: Treatment response is the degree to which an individual benefits from a treatment. This systematic review sought to identify and synthesize research evidence regarding individual characteristics that predict language treatment response among children with developmental language disorder (DLD).

Method: To be eligible for inclusion, articles needed to report results of an oral language treatment program in a group of children aged 4-10 years with identified DLD and also include a quantitative analysis of the relation between one or more pretreatment child characteristics and the outcome of language treatment. Seven databases (Cumulated Index to Nursing and Allied Health Literature, Dissertations and Theses Global, Education Resources Information Center, Linguistics and Language Behavior Abstracts, PsycINFO, Medline, and Web of Science) were searched for articles in June and July 2021, with search updates conducted in May 2023. Studies were categorized by the type of treatment provided, and results were synthesized qualitatively.

Results: The review included 31 studies, 1,551 participants with DLD, and over 300 statistical tests of a predictor's effect on language treatment response. Most studies (n = 21) included only monolingual speakers of English, with five studies including bilinguals and five including monolingual speakers of non-English languages. Language treatments targeted word learning in controlled or clinical conditions, grammatical learning in controlled or clinical conditions, or multiple language targets in clinical conditions. Predictors of treatment response are summarized across four categories: cognitive, demographic, pretreatment language levels, and other.

Conclusions: There were relatively few significant tests of the predictors of language treatment response. A central limitation of the evidence is that most included studies were designed to consider language treatment efficacy, not predictors of treatment response. Increasing research attention to the question of predictors of language treatment response in children with DLD is needed to enhance treatment and optimize outcomes for individual children.

发育性语言障碍儿童语言治疗反应的个体预测因素：系统回顾

目的：治疗反应是指个体从治疗中获益的程度。本系统综述旨在确定和综合有关预测发育性语言障碍（DLD）儿童语言治疗反应的个体特征的研究证据：要符合纳入条件，文章需要报告一组 4-10 岁已确定患有发育性语言障碍的儿童的口语治疗计划结果，并包括对一种或多种治疗前儿童特征与语言治疗结果之间关系的定量分析。我们在 2021 年 6 月和 7 月检索了七个数据库（护理和联合健康文献累积索引、学位论文全球数据库、教育资源信息中心、语言学和语言行为文摘、PsycINFO、Medline 和 Web of Science）中的文章，并在 2023 年 5 月进行了检索更新。研究按照所提供的治疗类型进行了分类，并对结果进行了定性综合：综述包括 31 项研究、1,551 名患有 DLD 的参与者以及 300 多项预测因子对语言治疗反应影响的统计检验。大多数研究（n = 21）只包括单语英语使用者，其中五项研究包括双语使用者，五项研究包括单语非英语使用者。在对照或临床条件下，语言治疗的目标是单词学习；在对照或临床条件下，语言治疗的目标是语法学习；在临床条件下，语言治疗的目标是多种语言。治疗反应的预测因素归纳为四类：认知、人口统计学、治疗前的语言水平和其他：结论：对语言治疗反应预测因素的重要测试相对较少。证据的一个主要局限是，大多数纳入的研究旨在考虑语言治疗效果，而不是治疗反应的预测因素。需要加强对DLD儿童语言治疗反应预测因素问题的研究关注，以提高治疗效果并优化个别儿童的治疗结果。补充材料：https://doi.org/10.23641/asha.26170006。

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.
