Naturalistic Developmental Behavioral Interventions (NDBIs) refers to interventions grounded in behavioral learning and developmental sciences. These interventions are commonly implemented in natural settings with children with autism and intellectual developmental disabilities. Although NDBI is a relatively new term in the behavior analytic…

The transition to adulthood is a significant step in every individual's life. Specifically, for individuals with disabilities, the transition process requires targeted planning for specific adulthood outcomes (e.g., employment, higher education, living skills, social skills, and community preferences). As such, parent and professional voices and…

Individuals with Autism (ASD) and Intellectual and Developmental Disabilities (IDD) exhibit poor post-secondary education employment outcomes compared to their disabled and non-disabled peers (Shattuck et al., 2012; Taylor et al., 2015). In addition, due to the COVID-19 pandemic school closures, students with ASD and/or IDD in post-secondary…

Over 50 years of research suggests that toilet training based on behavioral principles is effective for most individuals with intellectual and developmental disabilities (IDD). However, many adults with IDD are never effectively toilet trained. Lack of independent toileting is associated with detrimental physical, mental, and social experiences.…

Students of all ability levels, including those identified with intellectual disabilities (ID) and autism spectrum disorder (ASD), can benefit from improving their ability to take their knowledge out of the lower-order learning realm and transferring or applying into higher-order learning. Practical application of knowledge is important for…

Grounded in empathic education and the concept of rightful presence, this study moved beyond dominant inclusion paradigms, such as the inequitable host-guest 'hospitality' relationship; crucially, the study design prioritized equitable communication access, ensuring that all participants' stories were treated with equal reverence. This qualitative…

The purpose of this collective case study was to understand how special education teachers interpret and navigate the concept of the least restrictive environment (LRE) standard in providing educational support for students with intellectual disabilities and autism. The guiding theories for this study were behaviorism and social cognitive theory.…

Empathy is generally described as a multidimensional construct, consisting of cognitive and affective components. Researchers demonstrate that a better ability to understand and express empathy toward others is associated with positive social outcomes such as strong communication skills and meaningful social relationships. For individuals with…

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…

Grounded in the biopsychosocial models of expressive language in autism spectrum disorder (ASD) and fragile X syndrome (FXS), this dissertation included two novel studies that examined the role of biological (i.e., physiology), psychological (i.e., autistic traits, anxiety symptoms, and child affect) and social (i.e., communication partner…

Awareness of autism is rising, yet social determinants of health continue to impact rates, ages of diagnosis, and diagnostic load. Different psychiatric labels carry stigmas; unequal rates of diagnoses may indicate biases in the healthcare system. This study investigates six prior diagnoses (ADHD, disorders of conduct, adjustment, anxiety, mood,…

For students with Autism Spectrum Disorder and comorbid Intellectual Disability (ASD/ID), effective post-secondary transition services are vital. Despite the research-supported transition success of many individuals with ASD, there is a lack of evidence on the effectiveness of suitable supports for those with a comorbid ID. When considering young…

The purpose of the study was to analyze the historical patterns in the relationship between specific types of disabilities and frequency of drug abuse or weapon offenses in public schools in the United States using the U.S. Department of Education Open Data Platform's (n.d.) data sets from 2011-2012 through 2020-2021. The problem is that students…

The purpose of this qualitative, descriptive study was to explore how parents describe their roles in building the social, emotional, and cognitive success of their children with intellectual disabilities or autism during their child's transition to adulthood regarding starting a career and independent living. The theoretical foundations were…
