Toward evidence-based literacy interventions for children with severe and multiple disabilities

Area of Science:

• Pediatric Education
• Special Education
• Developmental Psychology

Background:

• Children with severe and multiple disabilities (SMD) exhibit significant lifelong challenges in literacy acquisition.
• Difficulties in vocabulary and phonological awareness are prominent in children with SMD.
• Environmental factors, including competing health needs and limited resources, can impede literacy learning.

Purpose of the Study:

• To explore factors influencing literacy acquisition in children with severe and multiple disabilities.
• To identify effective instructional strategies and environments for promoting literacy in this population.

Main Methods:

• Literature review of existing research on literacy development in children with SMD.
• Analysis of environmental and intrinsic factors affecting literacy learning.
• Examination of technology-supported educational settings.

Main Results:

• Literacy difficulties in children with SMD are multifactorial, involving both intrinsic and environmental influences.
• Environmental barriers include prioritizing non-literacy needs, limited access to adapted materials and communication supports, and insufficient instructional time.
• Technology-supported environments with diverse word study, text-based instruction, and print exploration foster literacy progress.

Conclusions:

• Evidence supports the use of technology-enhanced, comprehensive literacy instruction for children with SMD.
• Clinicians and educators can leverage existing research to adapt and improve literacy interventions.
• Further research is needed to expand effective literacy practices for this diverse group.
