Explicit Grammatical Intervention for Developmental Language Disorder: Three Approaches.

Area of Science:

• Linguistics
• Speech-Language Pathology
• Developmental Psychology

Background:

• Developmental Language Disorder (DLD) impacts syntactic abilities in school-aged children.
• Effective grammatical intervention requires systematic approaches tailored to individual needs.
• Existing interventions often lack comprehensive evidence for widespread clinical adoption.

Purpose of the Study:

• To summarize shared principles and evidence for three sentence-level (syntactic) grammatical intervention approaches.
• To discuss clinical resources and propose future research directions for syntactic interventions.
• To advance understanding and adoption of effective practices for school-age children with DLD.

Main Methods:

• Overview of three syntactic intervention approaches: MetaTaal, SHAPE CODING, and Complex Sentence Intervention.
• Description of principles, examples, and supporting evidence for each approach.
• Focus on children aged 5–16 years with developmental language disorder.

Main Results:

• All three approaches utilize detailed grammatical analysis for target selection.
• Interventions feature explicit, systematic presentation with multimodal representations and engaging activities.
• Clinically feasible intervention intervals and intensities have demonstrated measurable effects.

Conclusions:

• Syntactic intervention effectiveness can be maximized through further research, including studies in diverse languages.
• Development of practical clinical tools for target selection, outcome measurement, and intervention tailoring is needed.
• Continued research is essential to enhance grammatical interventions for school-age children with DLD.
