Challenging behavior in adults with intellectual and developmental disabilities (IDD) can lead to decreased quality of life and social and community inclusion. Compared to research with children there is relatively limited research on effective behavior support interventions for adults with disabilities. The Prevent-Teach-Reinforce (PTR) program…

Studies showed that children with Developmental Disabilities (DD) have communication and social difficulties; consequently, they are more likely to display disruptive behaviors. During daily interactions, disruptive behaviors can pose difficulties for individuals such as siblings, peers, parents, and educators. In KSA, parental involvement in…

Access to inclusive school settings is associated with many benefits for students with intellectual and developmental disabilities in the areas of academics (Agran et al., 2020; Kurth & Mastergeorge, 2010), social skills (Kleinert et al., 2015; Lyons et al., 2011; Schwab et al., 2015), and communication skills (Ballard & Dymond, 2017;…

The prevalence of challenging behavior, such as aggression, self-injurious behavior, tantrums, and noncompliance with everyday expectations among young children with intellectual and developmental disability (IDD), is higher than the prevalence of challenging behavior for children without disabilities. Without appropriate intervention, challenging…

Functional behavior assessment (FBA) is an integral component of treatment development for students with intellectual and developmental disabilities. The continuum of FBA methods includes indirect, direct, and functional analysis assessment methods. However, there is not a standard for the best approach to the FBA process. This evaluation compared…

Children with intellectual and developmental disabilities (IDD) frequently engage in escape-maintained problem behavior, which can limit their access to academic instruction and lead to placement in more restrictive educational settings. While there are function-based interventions to treat escape-maintained problem behavior, these interventions…

Students with intellectual and developmental disabilities (IDD) require intensive supports to make progress on literacy goals. These supports must often include methods to decrease challenging behaviors and increase engagement during instruction. In this study, I investigated whether computer-assisted instruction (CAI) may be one effective method…

A high proportion of people with developmental disabilities engage in challenging behavior compared to the general population (McClintock, Hall, & Oliver, 2003). Functional Communication Training (FCT) is an is an evidence-based intervention to address challenging behavior (Heath et al., 2015), but many people remain unable to access effective…

Student-teacher relationships (STRs) link to healthy development across behavioral, social, and emotional domains and promote healthy adjustment to educational environments and healthy attachments to educators. Previous research identifying variables impacting the quality of these relationships show that poor-quality relationships may be more…

Intelligence tests and adaptive behavior scales measure vital aspects of the multidimensional nature of human functioning. Assessment of each is a required component in the diagnosis or identification of intellectual disability, and both are frequently used conjointly in the assessment and identification of other developmental disabilities. The…

This dissertation is composed of four stand-alone yet linked chapters. Chapter 1 provides an overview of the theoretical underpinnings of the constructs of adaptive behavior and support needs and their evolution throughout history. There is also a review of the limited literature available examining the relationship between the two constructs that…

Everyone, including children with developmental disabilities, encounters stimuli they find aversive every day (e.g., the sound of a classmate tapping their pencil). These aversive stimuli may not be problematic for typically developing individuals, because they learn to behave in ways that allow them to escape or avoid this aversive stimulation.…

This study investigated the influences of children's adaptive skills, problem behaviors, and parent support systems (informal support and formal professional support) on maternal well-being (health and stress) in Taiwanese mothers of young children with developmental disabilities. The study examined the moderating effects of formal support and…

Previous research has shown that problem behavior maintained by social-negative reinforcement can be treated without escape extinction by enhancing the quality of positive reinforcement for an appropriate alternative response such as compliance. By contrast, negative reinforcement (escape) for compliance generally has been ineffective in the…

Asperger syndrome (AS) and high functioning autism are complex developmental disabilities that have a significant impact on the individual and his/her family. Asperger syndrome is characterized by challenges with understanding non-verbal communication, difficulties with social relationships, and restricted interests. Having a brother or sister…
