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…

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…

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…

This paper describes the FAB (Functionally Alert Behavior) Strategies approach to improve behavior in children and adolescents with complex behavioral challenges. FAB Strategies include evidence-based environmental adaptations, sensory modulation, positive behavioral support, and physical self-regulation strategies. FAB Strategies can be used by…

We manipulated relative reinforcement for problem behavior and appropriate behavior using differential reinforcement of alternative behavior (DRA) without an extinction component. Seven children with developmental disabilities participated. We manipulated duration (Experiment 1), quality (Experiment 2), delay (Experiment 3), or a combination of…

Background: The latter stages of dementia in individuals with Down syndrome are well documented; however, earlier cognitive and behavioural changes have only recently been described. Holland et al. suggested such early signs of dementia in this population are behavioural and are similar to those seen in frontotemporal dementia, but there is, as…

Individuals with intellectual and developmental disabilities are often prescribed psychotropic medication to treat behaviors such as aggression and self-injury. Evaluation of these medications is often based on caregiver report or changes in frequency of behavior. The purpose of this research was to characterize the rate and function of problem…

Conditional rates of problem behavior for weeks that followed medication decreases and no medication changes were compared for 12 individuals who exhibited severe problem behavior (e.g., self-injury, aggression). The results indicate that conditional rates of problem behavior were higher following medication decreases than following no changes in…

Research shows that after training in the philosophy and practice of mindfulness, parents can mindfully attend to the challenging behaviors of their children with autism. Parents also report an increased satisfaction with their parenting skills and social interactions with their children. These findings were replicated and extended with four…
