Abstract：Objective To systematically evaluate the effect of speech and language therapies and educational interventions on chil-dren with intellectual and developmental disabilities(IDD).
Methods A systematic review was conducted by searching relevant literature in PubMed,PsycINFO,ERIC,Cochrane Library and Web of Science databases,ranging from January,2018 to May,2024.
Results A total of eight English articles were included,from six countries including the United States,France,Italy,Nor-way,Poland and New Zealand,involving 610 children with IDD,from journals about speech language pathology,Down syndrome research and speech language hearing research.The publication time was mainly from 2018 to 2023.The age of the subjects was two to twelve years,and the main health conditions included intellectual dis-ability,autism and Down syndrome.The intervention methods included routine speech therapy(individualized therapy and group therapy),augmentative and alternative communication(device-assisted and sign language and picture cards),family-involved language training programs(parent training and family interaction),computer-as-sisted language learning(language learning software and telehealth),and play-based interventions(interactive games and structured games);15 to 150 minutes a time,one to ten times a week,for ten to 144 weeks.The out-comes were reflected in five aspects:increasing the vocabulary in speaking;improving the language comprehen-sion,symbol recognition and vocabulary comprehension;improving both expressive and receptive language skills;improving participation in game diversity and game participation levels,communication,social interaction and interaction skills;and improving overall language and non-verbal communication skills.
Conclusion Combining a variety of methods,such as individualized therapy,family participation,technologic assistance and interactive games,speech and language therapies and education are effective on spoken language production,language comprehension,speech production,social interaction and communication skills for children with IDD.
