Assessing pragmatics in early childhood with the Language Use Inventory across seven languages

Area of Science:

• Child language development
• Psycholinguistics
• Cross-cultural psychology

Background:

• The Language Use Inventory (LUI) is a parent-report measure assessing pragmatic language functions in young children (18-47 months).
• Its established reliability, validity, and utility in English (Canada) have driven global interest in its adaptation.
• Previous research highlights the importance of pragmatic language skills in early childhood development.

Purpose of the Study:

• To review the translation and adaptation processes of the LUI into seven languages: Arabic, French, Italian, Mandarin, Norwegian, Polish, and Portuguese.
• To evaluate the reliability and sensitivity of these translated LUI versions.
• To demonstrate the LUI's cross-cultural applicability in assessing children's language use.

Main Methods:

• A review of adaptation processes undertaken by seven international research teams.
• Analysis of reliability and developmental sensitivity data from studies utilizing the translated LUI versions.
• Synthesis of findings to assess the LUI's cross-cultural utility.

Main Results:

• Seven distinct research teams successfully translated and adapted the LUI into Arabic, French, Italian, Mandarin, Norwegian, Polish, and Portuguese.
• Data from studies using the translated versions confirmed their reliability.
• The adapted LUI versions proved sensitive to developmental changes in children's language use.

Conclusions:

• The Language Use Inventory is a reliable and valid measure of pragmatic language development across diverse linguistic and cultural settings.
• The social-cognitive and functional approach underpinning the LUI effectively captures language growth universally.
• The adapted LUI versions are valuable tools for both clinical assessment and research in child language development worldwide.
