This PhD research explores how speech and language therapists (SLTs) can enhance the communicative participation of children with developmental language disorder (DLD) through shared decision-making with parents and a strong focus on the child's personal and environmental context. The work is grounded in the International Classification of Functioning, Disability and Health – Children and Youth Version (ICF-CY) framework (WHO, 2007), and focuses on four key concepts: DLD, communicative participation, shared decision-making, and contextual factors.
