We reviewed single-case research studies examining the effects of behavioral interventions for self-injurious behavior (SIB) in young children with autism and developmental disabilities. Systematic searches of electronic databases, journals, and reference lists identified 46 studies (66 participants younger than the age of 12) meeting inclusion criteria. Studies were examined based on (a) participant demographics, (b) topography and function of SIB, (c) type of functional behavior assessment (FBA), (d) intervention procedures and outcomes, and (e) experimental design and measurement. Intervention strategies were categorized as antecedent manipulations, teaching behavior, consequence-based procedures, and/or extinction procedures. Positive outcomes were reported for 78% of participants in the reviewed studies and 88% of the participants were diagnosed with autism. Results suggest the effectiveness of behavioral interventions to decrease SIB for young children with disabilities; however, the frequent use of packaged interventions without component analysis limits the conclusiveness of any treatment recommendation. Suggestions for future research are discussed.
A multiple baseline design across participants was used to demonstrate the effects of a script-training procedure on the peer-to-peer communication of 3 children with autism spectrum disorder during group play with peers. Both scripted and unscripted initiations as well as responses to peers increased for all 3 participants. Stimulus generalization across novel toys, settings, and peers was observed. Novel unscripted initiations, responses, and appropriate changes in topics during peer-to-peer exchanges were analyzed by considering the cumulative frequency of these behaviors across phases of the study. Treatment gains were maintained during 4-week follow-up sessions. Results are discussed in terms of recommendations for practitioners, response variability, and potential future avenues of research.
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.
Children with autism spectrum disorder (ASD) and other developmental disabilities are at risk of isolation from same-aged peers. Furthermore, research indicates that even in inclusive settings, children with ASD benefit from targeted interventions and support. Among the social communication skills that are frequently absent in children with ASD is joint attention. Joint attention can be defined as shared engagement between two individuals on a third object or event and has been identified as potential pivotal skill for later development of age-appropriate social skills and communication. A growing body of literature documents effective intervention on joint attention skill for young children with ASD; however, few studies document the effects of an intervention mediated by a natural change agent. In the present study, independent concurrent multiple-baseline designs were used to evaluate the impact of a joint attention intervention combined with peer training on the response to joint attention (RJA) behaviors exhibited by seven preschoolers with ASD. Results indicated that RJA behaviors increased overall, the seven peers were able to carry out a simple intervention with fidelity, and that both bids from peers and responses to those bids increased following intervention. Limitations and opportunities for future research are discussed.
Individuals with disabilities who are English learners (ELs) and communicate using speech generating devices (SGDs) may demonstrate a preference for instructional language and language output of their SGDs. The influence of interventionist language on the preference of SGD language output and frequency of mands was examined using an alternating-treatments design with an embedded concurrent-chain arrangement with a 10-year-old with Down syndrome whose heritage language was Spanish. Language preference assessment for ELs is recommended because heritage language may be preferred for children with disabilities who use SGDs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
