Continued catch-up and language delay in children adopted from China

Area of Science:

• Child Language Acquisition
• Developmental Psychology
• Speech-Language Pathology

Background:

• Internationally adopted children often exhibit rapid initial language acquisition.
• Long-term language development trajectories, particularly for lower-performing children, remain less understood.
• Preschool years are critical for language development and academic readiness.

Purpose of the Study:

• To investigate the continued language development of low-performing internationally adopted preschoolers.
• To determine if extended English language exposure leads to significant language gains.
• To compare the progress of low-performing children with their peers.

Main Methods:

• Longitudinal study of 55 internationally adopted preschoolers from China.
• Re-assessment of the 10 lowest performers after approximately two years.
• Comparison of gain scores and performance against age- and duration-matched peers.

Main Results:

• Over half of the low-scoring children demonstrated clinically significant language gains.
• As a group, low performers continued to score below their matched peers.
• Gains were observed despite approximately two additional years of English language exposure.

Conclusions:

• Continued English language exposure supports development in internationally adopted children.
• Some children, particularly those starting with lower scores, may require targeted interventions.
• Developmental pace may not be uniform, highlighting the need for ongoing assessment.
