What this trial studies

This project focuses on children aged 4-9 diagnosed with Developmental Language Disorder (DLD), aiming to explore alternative treatment methods that can be implemented in typical settings. The study will assess the effectiveness of recast therapy and syntax stories delivered by parents or clinicians, while also identifying barriers to implementation. By examining the feasibility and acceptability of these interventions, the research seeks to enhance long-term language outcomes for children with DLD. The goal is to provide a more accessible treatment approach that can be integrated into everyday life.

Who should consider this trial

Good fit: Ideal candidates are children aged 4-9 who are primarily English speaking and diagnosed with developmental language disorder.

Not a fit: Patients with a diagnosis of Autism or those who do not meet the specified language and hearing criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more effective and accessible language interventions for children with developmental language disorder.

How similar studies have performed: Other studies have shown promise in using parent coaching and alternative delivery methods for language interventions, suggesting potential success for this approach.
