A functional behavior assessment is an evidence-based process that identifies the function of challenging behaviors in order for educators to develop behavior intervention plans for students with disabilities. All behaviors are under stimulus control and research indicates that behaviors typically serve four functions: tangible, escape, attention,…

As a treatment for escape-maintained problem behavior, differential reinforcement of alternative behavior (DRA) is typically initiated by reinforcing compliance on a dense reinforcement schedule. This work schedule is then progressively thinned such that the individual is required to complete more work, up to some socially acceptable terminal…

Many individuals diagnosed with intellectual and developmental disabilities (IDD) are uncooperative during routine dental exams, leading to poor oral health in this population. Few studies have evaluated methodologies for preparing dental students and professionals to work effectively with patients diagnosed with IDD. In this study, experimenters…

Over the past several decades, we have developed quality behavioral assessments and interventions for challenging behaviors among individuals with a variety of severe developmental and cognitive disorders. These assessments and interventions have been used to educate family members on how to understand and intervene with these behaviors at home…

Background: The feasibility of using typically developing siblings as social interaction intervention agents has been suggested in the literature addressing interactions and relationships between children with disabilities and their siblings. However, the outcomes are not completely understood. Objective: This study evaluated an intervention that…

Children and adolescents with intellectual and developmental disabilities (IDD) are more likely to engage in challenging and interfering behavior than their typically developing peers, which has been linked to many negative outcomes. The most effective interventions to address challenging and interfering behavior incorporate function-based…

To date, most studies seeking to explore the impact of COVID-19 school closures on student outcomes have focused on cognitive/academic losses. This study explores changes in adaptive behaviors experienced by children and youth with autism spectrum disorders or other developmental disabilities when in-person, one-to-one behavior training was…

Background: There is empirical evidence that a developmental language disorder (DLD) in early childhood leads to behaviour problems. However, it is still not clear how changes in language proficiency in these children influence the presence of behaviour problems. Aims: The aim of this study is to examine if changes in language proficiency are…

Background: Previous evaluations of community PBS teams have not investigated whether behaviour change is both statistically reliable and clinically significant. Few previous studies have reported quality of life (QoL) and social validity outcomes. Method: The present authors collected data on 85 people referred to a specialist PBS team. The…

This paper looks at the theory, research, applied aspects, and future possibilities of using strengths-based positive interventions in action, modified for people with no or low literacy with the use of the camera and video feedback. Action-based modifications of interventions, focusing on the emergence of character strengths and immediate visual…

Age-related behavioural change in Cornelia de Lange syndrome is poorly understood. We report a 7 year follow-up study of adaptive behaviour, autism spectrum disorder symptomatology, language skills and behavioural characteristics in 30 individuals with Cornelia de Lange syndrome, compared with 18 individuals with Cri du Chat syndrome. The…

The two most frequently used methods for assessing performance on chained tasks are single opportunity probes (SOPs) and multiple opportunity probes (MOPs). Of the two, SOPs may be easier and less time-consuming but can suppress actual performance. In comparison, MOPs can provide more information but present the risk of participants acquiring…

Children with intellectual and developmental disabilities (IDD) experience significant difficulties in attention, learning, executive functions, and behavioral regulation. Emerging evidence suggests that computerized cognitive training may remediate these impairments. In a double blind controlled trial, 76 children with IDD (4-11 years) were…

Previous studies have focused on whether a trial-based functional analysis (FA) yields the same outcomes as more traditional FAs, and whether interventions based on trial-based FAs can reduce socially maintained problem behavior. We included a full range of behavior functions and taught 3 teachers to conduct a trial-based FA with 3 boys with…

Research has shown that variability may be an operant dimension of behavior. One method of reinforcing response variability is to use a lag schedule of reinforcement (Page & Neuringer, 1985). Several studies have shown that a Lag 1 schedule is effective in increasing variable responding with human participants (e.g., Esch, Esch, & Love, 2009; Lee,…
