The Impact of Intervention Dose Form on Oral Language Outcomes for Children With Developmental Language Disorder.

Purpose The aim of this study was to extract key learning from intervention studies in which qualitative aspects of dosage, , have been examined for children with developmental language disorder (DLD)-in vocabulary, morphosyntax, and phonology domains. This research paper emerged from a pair of systematic reviews, aiming to synthesize available evidence regarding qualitative and quantitative aspects of dosage. While quantitative aspects had been experimentally manipulated, the available evidence for (tasks or activities within which teaching episodes are delivered) was less definitive.

Why Clinicians Choose Their Language Intervention Approach: An International Perspective on Intervention for Children with Developmental Language Disorder.

Purpose: Considerable progress has been made in recent years in generating external evidence underpinning interventions for children with developmental language disorder (DLD), but less is known about the practitioner decision-making process underpinning such interventions and whether such decisions are context specific or are internationally generalizable.

Methods: An online survey about clinical practice was developed by members of COST Action IS1406, an EU-funded research network, which included representation from 39 countries. The participants were 2,408 practitioners who answered questions in relation to their decision making for a specific child of their choosing with DLD.

The Influence of Quantitative Intervention Dosage on Oral Language Outcomes for Children With Developmental Language Disorder: A Systematic Review and Narrative Synthesis.

Purpose The aim of this study was to examine the degree to which quantitative aspects of dosage (dose, dose frequency, and total intervention duration) have been examined in intervention studies for children with developmental language disorder (DLD). Additionally, to establish the optimal quantitative dosage characteristics for phonology, vocabulary, and morphosyntax outcomes. Method This registered review (PROSPERO ID CRD42017076663) adhered to PRISMA guidelines.
