Research on treatment intensity in children with developmental language disorder (DLD) has undergone substantial development over the last decade. The aim of the present review was to analyse available publications as related to methodological quality, degree of scientific evidence, and the areas/aspects of language involved.
A systematic review of the scientific literature was conducted using the PRISMA guidelines. A total of 9 articles from 34 published investigations in the field were selected for review according to our inclusion criteria.
The articles addressed the effects of treatment intensity primarily considering expressive morphology and vocabulary. The methodological quality and levels of evidence provided by the studies were high. In general, the effect sizes of dependent variables were considered large.
The number of articles investigating treatment intensity in DLD is scarce. High variability of stimuli was associated with improvements in morphology, whereas vocabulary did not demonstrate the same association. Further research on treatment intensity is needed to address transference and generalisation of the treated abilities.
过去十年间，儿童发育性语言障碍（DLD）治疗强度的研究取得了实质性进展。本综述旨在分析与方法质量、科学证据程度以及涉及的语言领域/方面相关的现有文献。
采用 PRISMA 指南对科学文献进行系统综述。根据纳入标准，从该领域发表的 34 项研究中选择了 9 篇文章进行综述。
这些文章主要考虑表达形态和词汇，探讨了治疗强度的效果。研究提供的方法质量和证据水平都很高。一般来说，因变量的效应大小被认为是大的。
调查 DLD 治疗强度的文章数量很少。刺激的高度可变性与形态学的改善有关，而词汇则没有表现出同样的相关性。需要进一步研究治疗强度，以解决治疗能力的转移和泛化问题。
