Early intervention for toddlers with language delays: a randomized controlled trial

Area of Science:

• Child Development
• Speech-Language Pathology
• Pediatric Health

Background:

• Early language delays in toddlers can persist, impacting long-term development.
• Previous interventions have not consistently improved expressive language outcomes.
• Caregiver involvement is crucial for early childhood intervention success.

Purpose of the Study:

• To evaluate a caregiver-implemented communication intervention for toddlers at risk of persistent language delays.
• To assess the intervention's impact on both child language outcomes and caregiver strategy use.
• To address the limitations of prior interventions in improving expressive language.

Main Methods:

• A randomized controlled trial involving 97 toddlers (24-42 months) with language delays.
• Toddlers were assigned to either a caregiver-implemented intervention or usual care.
• Intervention involved 28 sessions teaching caregivers language facilitation strategies; outcomes measured by Preschool Language Scale, Fourth Edition.

Main Results:

• Caregivers in the intervention group significantly increased their use of language facilitation strategies.
• Children in the intervention group demonstrated significant improvements in receptive language skills.
• No significant improvements were observed in broad-based expressive language skills for the intervention group.

Conclusions:

• Caregiver training can enhance language facilitation strategies and yield short-term gains in receptive language skills.
• Further research is needed to optimize intervention dosage and identify strategies linked to specific child outcomes.
• Adaptations for diverse cultural and linguistic backgrounds are essential for broader applicability.
