Vocabulary Training for Language Developmental Disorders

(DLD Trial)

This trial aims to determine if Spanish-speaking caregivers can effectively teach science vocabulary to their children using an educational app and training video. Children will be randomly assigned to use either the app or books for vocabulary learning, with sessions occurring twice a week for about 30 minutes. The study seeks children aged 4-6 who speak Spanish at least half of the time and have language developmental disorders, along with caregivers who have a smartphone and speak fluent Spanish. Participants will engage in the study for 11 weeks, with testing at the beginning, middle, and end. This research seeks to improve language skills in children with language developmental challenges through a robust vocabulary intervention. As an unphased trial, this study offers caregivers a unique opportunity to actively contribute to research that could enhance educational tools for children with language developmental challenges.

The trial information does not specify whether you need to stop taking your current medications. It seems unlikely that medication changes are required, as the study focuses on language development and caregiver-child interactions.

Research has shown that vocabulary-building activities are generally safe for children with language development issues. Studies have found that these activities can enhance vocabulary without causing negative effects. Techniques such as parent-led language games integrate easily into daily life, making them safe and convenient for both parents and children.

Researchers are excited about this trial because it explores innovative ways to support language development in children with language developmental disorders. Unlike traditional methods that might rely heavily on professional therapy sessions, this approach empowers caregivers to be directly involved. By training caregivers to teach vocabulary during engaging science activities, this method could make learning more natural and integrated into daily life. Additionally, the caregiver-child book-sharing aspect promotes bonding while reinforcing language skills through regular reading sessions. This hands-on, family-centered approach could offer a more practical and accessible way to enhance language skills in affected children.

Research shows that vocabulary exercises can aid children with language development issues. Studies have found that children receiving specific vocabulary lessons often improve in understanding and using new words. For example, one study found that children scored higher on words taught directly. In this trial, one group of participants will receive a caregiver-delivered vocabulary intervention, with caregivers trained to teach target vocabulary during science activities. Another group will engage in caregiver-child book sharing, where caregivers read books on target science concepts with their child. This suggests that caregiver involvement in vocabulary lessons might enhance children's language skills.¹⁶⁷⁸⁹
