Does oral language underpin the development of later behavior problems? A longitudinal meta-analysis

Area of Science:

• Developmental Psychology
• Child Psychology
• Linguistics

Background:

• Early language development is crucial for cognitive and social-emotional growth.
• Behavioral problems in school-aged children can have long-term negative consequences.
• Previous research suggests a link between language abilities and behavioral outcomes.

Purpose of the Study:

• To estimate the overall weighted mean effect of the relationship between early language skills and later behavior problems in school-aged children.
• To synthesize existing evidence through meta-analysis.

Main Methods:

• A systematic literature search identified 19,790 reports, from which 25 unique datasets and 114 effect sizes were extracted.
• Robust variance estimation and random-effects meta-analytic techniques were employed for synthesis.
• Moderator analyses were conducted to identify significant predictors of the association.

Main Results:

• A small, negative overall correlation (r = -.14) was found between early language skills and later behavior problems.
• Controlling for demographic variables did not significantly alter the inverse relationship (r = -.16).
• Receptive language, parent-reported behavior, gender, and age were significant moderators.

Conclusions:

• Findings corroborate previous meta-analytic and longitudinal studies on the language-behavior link.
• Areas for future research include refining measurement techniques for language and behavior.
• Prospective longitudinal studies using diverse measures are warranted to further elucidate these relations.
