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 gaps in the literature. A mega-review of literature reviews, systematic reviews, and meta-analyses on interventions using aided augmentative and alternative communication (AAC) interventions for children with intellectual and developmental disabilities from 2000 to mid-2020 was conducted. Participant and interventionist demographics, interventions, settings, outcomes, and recommendations of each review were reported and summarized. A MeaSurement Tool to Assess systematic Reviews Revised (AMSTAR 2; Shea et al., 2017) was used to examine the methodological rigor of 84 included reviews. Over the past 20 years, published reviews have increased slightly in methodological rigor but demonstrate a number of methodological weaknesses that detract from the strength of evidence for AAC interventions with this population. Suggestions for improving the methodological rigor of literature reviews and areas for future research specific to AAC interventions are discussed.
建立基于证据和研究的实践依赖于在综述和荟萃分析中对个体研究进行研究综合。通过综合综述进一步总结关于特定主题的科学证据，是确定具有强有力证据基础的实践以及识别文献中方法学弱点和差距领域的一个需要关注的方面。对2000年至2020年年中关于使用辅助增强和替代沟通（AAC）干预措施对智力和发育障碍儿童进行干预的文献综述、系统评价和荟萃分析进行了一项大型综述。报告并总结了每项综述的参与者和干预者人口统计学特征、干预措施、环境、结果和建议。使用一种修订的评估系统评价的测量工具（AMSTAR 2；Shea等人，2017年）来检查84篇纳入综述的方法学严谨性。在过去20年中，已发表的综述在方法学严谨性方面略有提高，但仍表现出一些方法学弱点，这些弱点削弱了针对该人群的AAC干预措施的证据强度。讨论了提高文献综述方法学严谨性的建议以及针对AAC干预措施未来研究的领域。
