Early language intervention improves behavioral adjustment in school: Evidence from a cluster randomized trial

Area of Science:

• Child Psychology
• Developmental Psychology
• Education

Background:

• Oral language proficiency is vital for psychosocial development in children.
• Children with language difficulties often exhibit more behavioral problems.
• Early intervention can mitigate these challenges.

Purpose of the Study:

• To investigate the impact of an oral language intervention on children's behavioral adjustment.
• To determine if improvements in behavioral adjustment are mediated by language skill enhancement.

Main Methods:

• A cluster randomized trial involving 1173 primary school children.
• The Nuffield Early Language Intervention (NELI) program was implemented over 20 weeks.
• Teacher ratings of behavioral adjustment were collected pre- and post-intervention.

Main Results:

• Children in the language intervention group showed significantly greater improvements in behavioral adjustment compared to the control group (d = 0.23).
• These behavioral improvements were not mediated by concurrent gains in oral language skills.
• The intervention's structured teaching sessions, emphasizing attention and behavior regulation, appear to be the key factor.

Conclusions:

• Oral language intervention programs can positively impact behavioral adjustment in young children.
• The benefits to behavior may stem from the program's structure and focus on self-regulation, rather than solely language gains.
• This highlights the importance of considering broader developmental impacts in early intervention strategies.
