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…

Augmentative and alternative communication (AAC) refers to methods and tools that facilitate communication for individuals with limited functional speech. This study aims to present and analyse the research status of AAC interventions for children with special needs in mainland China using a bibliometric analysis approach. The researcher conducted…

Purpose: This scoping review aims to characterize the body of literature addressing literacy interventions involving young children (ages 2--8 years) who use or would benefit from aided augmentative and alternative communication (AAC). Method: A systematic search was conducted in six databases. The search yielded 33 intervention studies.…

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…

The purpose of this review was to assess the effectiveness of tablet-based speech-generating devices (SGDs) in improving communication skills for individuals with autism spectrum disorder (ASD). A total of 31 single-case design intervention studies involving 84 individuals with ASD were reviewed and included in the analysis. We calculated Tau-U to…

The authors conducted a systematic review of the literature, including studies that used a single-case design (SCD) and taught augmentative and alternative communication (AAC) use to adults with complex communication needs. The purpose of this review was to describe (a) adults receiving AAC intervention, (b) components of the interventions used,…

Purpose: This systematic review evaluates the latest available evidence regarding augmentative and alternative communication (AAC) interventions in children from 0 to 6 years old diagnosed with various disabilities. Method: A systematic search was conducted in MEDLINE (OVID), PsycINFO (EBSCO), ERIC (ProQuest), SCIELO (WOS), Teacher Reference…

People with severe/profound intellectual disability experience challenges in communicating and require their communication partners to adapt to their means of communication. Augmentative and Alternative Communication (AAC) is recognised as a potential means to meet their communication needs. Interventions need to be aimed at both the individual…

Purpose: The purpose of this article was to conduct a systematic review of the literature on teaching or increasing the use of augmentative and alternative communication (AAC) by students with significant intellectual disabilities and complex communication needs (CCNs) within inclusive school settings. Method: A systematic review of research…

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…

Currently, a small number of studies discuss augmentative and alternative (AAC) interventions in low- and middle-income countries (LMICs). The primary purpose of this scoping review was to summarize the current evidence base on communication-based interventions and partner training in LMICs, to explore and identify gaps in the AAC evidence base…

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 systematic review evaluated the effect of speech interventions with the addition of speech generating devices on vocalizations of children with autism spectrum disorder (ASD) and complex communication needs. This review synthesized information across 18 studies published in the past three decades (1990-2023) with the primary focus on the…

As 30% of individuals with autism spectrum disorder (ASD) demonstrate difficulties with vocal output, augmentative and alternative communication (AAC) intervention can provide a means for those persons to have the ability to communicate with others. To determine the most effective mode of AAC for individuals with ASD, practitioners must have…

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…
