Core vocabulary is defined as "lexical items that are accepted as being central and indispensable to language use" (Bell, 2012, p. 1). Use of core vocabulary is common amongst professionals who teach augmentative and alternative communication (AAC) to individuals with disabilities. Although the use of AAC is often classified as an…

Many children with intellectual and/or developmental disabilities benefit from augmentative and alternative communication strategies (AAC) to increase their communicative competency. Furthermore, caregiver-implemented AAC interventions are an effective and efficient strategy to improve communication outcomes. We reviewed the caregiver-implemented…

This meta-analysis reviews the literature on communication modes, communicative functions, and AAC type examined during interventions with school-age participants with ASD and/or ID who experience CCN. Considering potential differences related to outcomes taught could help identify the most effective means of individualizing AAC interventions. We…

For children with autism or intellectual and developmental disabilities who also have complex communication needs, communication is a necessary skill set to increase independence and quality of life. Understanding the how, where, and communication style being taught is important for identifying deficits in the field as well as which interventions…

Background: A significant proportion of adults with intellectual disabilities (ID) experience speech, language and communication difficulties which are associated with poor physical and mental health outcomes. Speech and language therapy (SLT) interventions are an important way to address these communication difficulties, yet there is limited…

Establishing evidence- and research-based practices relies upon research synthesis of individual studies in reviews and meta analyses. Further summarizing scientific evidence about a specific topic by synthesizing reviews is an area of need to determine practices that have a strong evidence base and to identify areas of methodological weakness and…

This review investigated virtual reality and augmented reality (VR/AR) communication interventions for children, adolescents, and adults with communication disability and neurodevelopmental disorders, as well the feasibility of these technologies. A search of five scientific databases yielded 5385 potentially relevant records of which 69 met…

In the current investigation, we reviewed the literature on mand training for individuals with intellectual and developmental disabilities (IDD) in schools. Ninety-three studies met our inclusion criteria including 225 individual participants. Data were extracted related to participant demographics (e.g., age, disability, response form) and study…

Enabling functional communication is critical for accessibility in school and society for all pupils. This systematic review analyzed the results of educational studies on developing communication skills for learners ([less than or equal to]21 years) with autism spectrum disorder and comorbid intellectual disability. Systematic database searches…

Although functional communication training (FCT) is an effective intervention for increasing appropriate forms of communicative behaviors and decreasing inappropriate forms of communication (i.e., challenging behavior) in students with disabilities, its effectiveness might depend to some extent on the expertise of the interventionist. The purpose…

Effective vocational instruction is an essential aspect of preparing students with intellectual and developmental disabilities (IDD) for the world of work. We systematically reviewed research on instructional methods used to teach employment skills to secondary students with IDD. We identified 56 studies involving 766 participants with IDD. Four…

Deficits in communication in people with disabilities are a major cause of challenging behaviors. Functional communication training (FCT) is one treatment developed to address both challenging behavior and instruction in replacement communicative behaviors by determining the function, or reason, the behavior occurs and developing a communication…
