Improving language disorders in children with Down syndrome by applying a multimodal intervention program structured in accordance with the Theory of Multiple Intelligences

Down syndrome can cause disorders of both cognitive abilities, but also, most often, cause a deficit in language development, and their speech and language develop later and more slowly, hence the importance of finding optimal ways to improve. The purpose of the research is the development, implementation, and validation of the effectiveness of the speech therapy intervention program structured in accordance with the Theory of Multiple Intelligences (Howard Gardner). Participants with Down syndrome in this study obtained significant improvements in the areas of language and communication assessed after receiving the systematized speech therapy intervention, based on the theory of multiple intelligences.
