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…

Background: People with neurodevelopmental disabilities are frequently prescribed or administered psychotropic medication, particularly to manage behaviours of concern. Reducing inappropriate psychotropic use has been the target of international research and policy for several decades. Methods: Six electronic databases were searched for…

Children with developmental disabilities often have difficulty completing complex multistep tasks, such as daily living skills or leisure and play skills, which often occur in children's homes. The use of visual supports can increase the predictability of routines and clarify behavioral expectations for children with developmental disabilities.…

A systematic literature review was conducted to examine the evidence for peer network interventions for students with intellectual and developmental disabilities (IDD). Fifteen studies were identified and evaluated for methodological rigor using the quality indicators published by the Council for Exceptional Children (CEC) and by examining the…

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…

Applied behavioral pharmacology explores how drugs may influence problem behavior in persons with intellectual and developmental disability (IDD). A comprehensive review was conducted featuring single-case experimental designs in the domain of applied behavioral pharmacology to evaluate and report on study quality. Studies included in the review…

Background: This review explored (1) what digital psychological wellbeing interventions for family carers of people with intellectual and developmental disabilities were reported in the literature, (2) evidence about their effectiveness, (3) factors affecting their implementation and (4) experiences of family carers who attend them. Methods: Seven…

Developmental support agencies support many adults with intellectual disabilities in the community. Unfortunately, these adults often exhibit high rates of challenging behaviour, which present significant pressures on these service providers. Agencies need to develop effective means of increasing their capacity to provide quality support. Previous…

The present study explored the shift from understanding to intervention to population impact in the empirical research published in this journal at five points of time over 40 years since the release of DSM-III. Two-thirds of the more than 600 original studies identified involved basic research, a pattern that is consistent with previous analyses…

This review aimed to analyze the psychometric properties of standardized instruments that are used to measure pragmatic intervention effects in children with developmental language disorder. Following PRISMA structure, a comprehensive literature research was conducted in five electronic indexing databases: Central, PubMed, Medline, Web of Science…

Teaching science education has remained limited for students with intellectual and developmental disabilities (IDD), which, in turn, has resulted in an ongoing discrepancy between these students and their typically developing peers for decades. Although there is a growing body of research in effective teaching approaches aimed at overcoming this…

Individuals with autism spectrum disorders and other developmental disabilities (ASD/DD) often need to be explicitly taught personal hygiene skills (e.g., menstrual care, penile care and washing and cleaning of intimate body parts). The taboo and private nature of intimate care skills has often led practitioners to avoid teaching these skills…

Background: Direct Support Professionals (DSP) work closely with individuals with intellectual and developmental disabilities (I/DD) and can play an important role in helping these individuals get treatment when they are also experiencing mental health concerns (MHC). Methods: We employed a systematic review search techniques to identify 15…

Transition can refer to the termination of one activity and initiation of another activity or movement across locations. Transitioning is a fundamental skill required for independence. However, individuals with developmental disabilities often require direct additional instruction to ensure their independent transitioning. Video modeling, an…

Physical activity has many benefits, but many individuals with developmental disabilities fail to exercise regularly. Procedures in which consequences were arranged for exercising, alone or as part of a treatment package, have consistently increased physical activity by members of this population. We review 19 studies that arranged such…
