Education has changed over the past 20 years to accommodate students with autism spectrum disorder (ASD) in inclusive classrooms. The problem addressed by this study was that elementary school teachers of students with autism spectrum disorder (ASD) often struggle to know which evidence-based practices (EBPs) to utilize to effectively educate…

The topic of the three chapters of this dissertation is empowering caregivers of children with or at high likelihood for autism to implement interventions in home settings with high fidelity to promote their child's social communication development. Chapter 1 provides an overview of the previous studies focused on caregiver-implemented early…

The COVID-19 pandemic increased the use of remote service delivery in early childhood intervention (EI), and this increased use is promising for young children with disabilities living in rural communities. However, the increase in remote service delivery requires a greater understanding of using evidence-based practices (EBP) delivered by EI…

Autism spectrum disorder (ASD) research has yet to leverage "big data" on the same scale as other fields; however, advancements in easy, affordable data collection and analysis may soon make this a reality. Indeed, there has been a notable increase in research literature evaluating the effectiveness of machine learning for diagnosing…

Discrete trial teaching (DTT) is a commonly implemented and evaluated teaching procedure for individuals diagnosed with autism spectrum disorder (ASD). As such, DTT is often a procedure that behavior analytic practitioners are required to learn how to impliment. Additionally, parents are often encouraged to learn how to implement DTT to supplement…

Background: Speech-language pathology services are among the most frequently accessed services for young autistic children. Therefore, understanding the nature of these services, what challenges these clinicians face, and what supports they value is critical for developing appropriate policies and practices that can maximize positive outcomes for…

Children with autism spectrum disorders (ASD) are at greater risk for reading difficulties, and for many children, the promotion of reading fluency is an appropriate intervention goal. However, few studies have specifically examined the use of repeated reading (RR) with young children with ASD. The present study used a RR intervention in…

This study investigated the feasibility of recruiting and assessing infants with prodromal autism characteristics in the first year of life via telehealth. Participants included 41 infants (Mage = 10.51 months, 51.2% female, 80.5% White) whose parents had concerns about social communication delays or autism. All infants met concerns criteria on a…

In the field of education and health care, researchers and educators attempt to close the diagnosis/identification and service gaps that persist for low-resourced, underrepresented families with children with autism. One group of families particularly difficult to engage in research and interventions is undocumented immigrant families. We know…

This study evaluated the effects of an early education inclusion program for children with autism: 'Understanding our Peers; the Early Years'. A series of children's books were created outlining the core behavioural features of autism and how the characters in the books were able to understand these behaviours and accommodate the needs of the…

Purpose: Children with autism spectrum disorder (ASD) are at risk for exclusion from play with their peers due to difficulty with communication skills. Video augmentative and alternative communication (AAC) technology has the potential to support communication within the context of play using videos with integrated visual scene displays. This…

Early Intensive Behavioural Intervention (EIBI) is effective for preschoolers with autism spectrum disorder (ASD). Parental measures are rarely included in EIBI effectiveness studies, yet parental distress and lower self-efficacy are associated with poorer child outcomes. Parents of preschoolers with ASD (N = 485) were surveyed at baseline (T1),…

Following the outbreak of the COVID-19 pandemic, the U.S. government declared a state of emergency and many applied behavior analysis clinics temporarily closed. The current study described a pilot of an existing manualized caregiver behavior skills training, the Online and Applied System of Intervention Skills (OASIS), to promote telehealth…

Emotional and behavioral problems (EBPs), such as anxiety, overactivity, and aggression, can influence the diagnosis of autism spectrum disorder (ASD). The gold standard diagnostic tool for ASD, the "Autism Diagnostic Observation Schedule--Second Edition," includes three items ("E-codes") for EBPs that are frequently associated…

Including students with autism spectrum disorders (ASD) in general education is a common practice today. However, there are relatively few mathematics interventions for students with ASD in secondary education. There is also a lack of literature exploring mathematics interventions that reflect grade-level academic requirements and are adapted for…
