First they will conduct a literature search that focuses on the use of AAC among individuals with disabilities. Research Design and Methods: Researchers will use meta-analysis, a method of quantitative research synthesis that uses prior study results as the unit of observation. AAC includes any means of communication intended to replace or supplement communication, particularly speech, in individuals with complex communication needs. Malleable Factors: The malleable factors under investigation are variables related to instruction in AAC (i.e., type of instructional protocols implemented, implementers, and settings). Sample: The research articles reviewed in the meta-analysis may include individuals ages 0-22 with IDD, including autism spectrum disorder (ASD), intellectual disability (ID), other developmental disabilities (DD), and complex communication needs (cannot communicate via age-expected speech). Setting: The research articles reviewed in this meta-analysis will include studies conducted in natural settings, including the home, classroom, community, place of employment, or clinic. Products will also include peer-reviewed publications and presentations. Products: The products of this study will include results from a meta-analysis describing relationships between AAC and education outcomes for individuals with IDD and potential differences in these relationships based on the instructional protocol, implementer, and educational setting. Last, the research team will conduct several meta-analyses to determine the associations between AAC and social/communicative and behavioral outcomes for students with IDD and whether associations differ by type of instructional protocol, implementer, and educational setting. For articles that meet inclusion criteria (see below), the research team will evaluate the quality of research designs and evidence to determine whether AAC can be considered an evidence-based practice.

Project Activities: The research team will start by identifying articles focused on the use of AAC for individuals with IDD. Ultimately, the results will provide important information to researchers on the need for the development of AAC interventions and to practitioners and caregivers on how best to individualize AAC interventions. The project will also examine whether relationships differ based on the type of instructional protocols implemented (e.g., Picture Exchange Communication System, functional communication training, and other behavioral techniques), implementers (e.g., educator, paraprofessional, parent/caregiver) and settings (e.g., home, classroom, clinic).

This project aims to address this gap by conducting a meta-analysis to explore relationships between AAC and education outcomes for individuals with IDD. Although AAC is widely used in educational settings, it is unclear for whom and under what conditions it is most effective. Purpose: The purpose of this project is to conduct a comprehensive meta-analysis to determine whether augmentative and alternative communication (AAC) is associated with improved outcomes (e.g., behavior and communication) for individuals with intellectual/developmental disabilities (IDD).
