Summary
This study translated the Language Use Inventory (LUI) into Brazilian Portuguese, finding it reliable for assessing preschooler language pragmatics and aiding early diagnosis.
Area of Science:
- Linguistics
- Psycholinguistics
- Speech-Language Pathology
Background:
- The Language Use Inventory (LUI) is a key tool for assessing pragmatic language skills.
- Adaptation of assessment tools is crucial for cross-cultural validity and reliable data collection.
Purpose of the Study:
- To translate and culturally adapt the English Language Use Inventory (LUI) into Brazilian Portuguese.
- To establish the reliability and validity of the Brazilian-Portuguese version of the LUI for use with preschool-aged children.
Main Methods:
- Translation and back-translation process with sociocultural adaptation for Brazilian Portuguese.
- Internal consistency assessed using Cronbach's alpha coefficient.
- Pilot study involving 43 parents of children aged 24–47 months in São Paulo, Brazil.
Main Results:
- High internal consistency (Cronbach's alpha > 0.98) for the adapted instrument, indicating reliability.
- Pilot study revealed an age effect: older children used fewer gestures and more words/syntactic constructions.
- The Brazilian-Portuguese LUI demonstrated reliability for evaluating pragmatic language skills.
Conclusions:
- The translated and adapted Brazilian-Portuguese LUI is a reliable instrument for assessing preschoolers' language pragmatics.
- This validated tool can facilitate early diagnosis and intervention for language disorders in Brazilian children.
- Further detailed analyses are recommended to fully leverage the diagnostic potential of the LUI.

01:31Translation
Lesson: Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.

01:22Language Development
Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

01:22Self-Report Tests of Personality
Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.
