Although function-based treatments have been proven to decrease challenging behavior, it is unclear whether these results translate to socially significant outcomes. In fact, researchers rarely analyze what happens outside the highly controlled setting in which behavior analytic sessions typically occur. In our first study, we used a changing…

In recent years, there has been an increasing emphasis on the use of functional assessment (FA) in the selection of treatments for problem behaviors. Scholars now generally accept that an understanding of the antecedents and consequences of problem behavior, achieved through a FA, is necessary to select the most effective treatment procedure. Yet,…

This dissertation was designed to determine which behavior analytic intervention was more effective in the treatment and reduction of mouthing non-nutritive substances in children diagnosed with autism. This study included four participants in an A-B-A reversal design with a component analysis across four intervention phases. The study…

As the rates of Autism Spectrum Disorder (ASD) increase, so does the need to provide high-quality and empirically validated supports across the lifespan. Despite most of an individual's life taking place in adulthood, it is well-documented that the supports and services for adults with ASD are severely lacking. This is evidenced by outcomes…

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;…

Decades of empirical research has demonstrated that exclusionary discipline is a racialized mechanism through which schools systematically remove Black and brown children from the learning environment. Although development of Functional Behavior Assessments (FBAs) and linked behavior support plans has been identified as a solution to exclusionary…

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…

Teachers do not have adequate training or support to effectively address challenging behaviors exhibited by students. The purpose of this study was to obtain insight into the benefits and challenges of a collaborative relationship between a behavior analyst and educators. The framework for this study is applied behavior analysis and its three-term…

Challenging behaviors are one of the basic problems that all pre- and in-service teachers have to be prepared to deal with in schools. In Thailand, it was found that challenging behaviors of students with disabilities had an effect on teachers' stress because many teachers perceived that they were lacking the knowledge and skills to deal with…

Function-based assessments and interventions are routinely used in school settings as an effective method to address problem behaviors that impede the learning of the student or others. When function-based interventions are not successful, it is often due to problems with treatment integrity (TI). Using an ABCBC single subject design, this study…

This study is based on the research of Dr. Ursula Delworth. The Assessment-Intervention of Student Problems (AISP) model that was first published in 1989 has stood the test of time and, in fact, foreshadowed the widely held practice of behavioral intervention that is seen on campuses today. Dr. Delworth referred to this group as a Campus…

This study examined the relations between child internalizing behavior problems and social competence in a sample of young children (N = 166) with autism spectrum disorders (ASD) as they transitioned to early schooling. Previous literature suggested higher rates of comorbid psychopathology in this population of children; however, a limited number…

I conducted two studies. First, I examined the applicability of discrete-trial functional analysis (DTFA) for identifying the function of problem behavior in three adults with a dual diagnosis of a significant intellectual disability and a mental illness. Results indicated clear patterns of problem behavior for each participant. Second, I used a…

Prevent-Teach-Reinforce (PTR) is a collaborative, standardized process that was developed as a way to address identified barriers to completing effective functional behavior assessments (FBAs) in public schools. Current research literature documents the effectiveness of the PTR process in decreasing problematic behaviors and increasing social…

The current study evaluated the efficacy of a training series designed to teach typical school-based behavior support professionals to build behavioral interventions from functional behavioral assessment (FBA) information. The study was conducted in three stages. First, a descriptive assessment examined the extent to which typical school team…
