Speech-Language Intervention for Language Disorder
Trial Summary
What is the purpose of this trial?
The purpose of this study is to determine the amount of speech-language intervention children with language impairment need to make vocabulary gains. The investigators hope to identify the optimal amount of intervention needed as well as the point at which adding more intervention is no longer beneficial. Participants will be randomly assigned (like a flip of a coin) to attend therapy either one time a week for 10 weeks (2 hours a session) or 4 times a week for 10 weeks (30 min per session). Each therapy session will follow a word learning intervention that is designed to increase children's word learning abilities using rich, robust word learning strategies within story book readings. The optimal amount of intervention relates to duration, dose, and frequency. Duration refers to how long the child is seen for (e.g., 10 weeks, 1 year). Dose represents the number of exposures to each new vocabulary word within a therapy session. Frequency represents the number of therapy sessions per week. The investigators will test the hypothesis that distributed learning leads to higher gains. The investigators propose that the greatest gains will be observed for children who receive high-frequency/low-dose or low-frequency/high-dose treatments as compared to children who receive high-frequency/high-dose or low-frequency/low-dose treatments. The investigators will test the hypothesis that for both low-frequency and high-frequency treatments, there is a point at which increases in treatment dose do not correspond to any additional gains in children's vocabulary skills during treatment. At the close of this four-year study, evidence concerning optimal treatment intensity of a word learning intervention will be instrumental for immediately informing speech-language pathologists in how much vocabulary treatment to prescribe as well as for designing additional clinical trials by our and other research teams.
Will I have to stop taking my current medications?
The trial information does not specify whether participants need to stop taking their current medications.
What data supports the effectiveness of the treatment Word Learning Intervention for Language Disorder?
Research shows that interventions focusing on word-finding strategies, such as semantic and phonological approaches, can significantly improve word retrieval in children with language disorders. These treatments have been shown to enhance word-finding abilities, suggesting that similar methods could be effective in the Word Learning Intervention.12345
Is the Speech-Language Intervention for Language Disorder generally safe for humans?
How does the Word Learning Intervention treatment differ from other treatments for language disorder?
The Word Learning Intervention is unique because it uses retrieval- and criterion-based learning strategies, which are designed to improve both the learning and retention of words in children with developmental language disorder. This approach focuses on actively recalling words and meeting specific learning criteria, which may enhance learning efficiency compared to other methods.311121314

Eligibility Criteria
This trial is for children aged 5 to nearly 7 with a primary diagnosis of language impairment, specifically in vocabulary. They must primarily speak English and score below the 10th percentile on certain vocabulary assessments. Children with autism, hearing loss, or severe cognitive disability are not eligible.Inclusion Criteria
