The establishment of reciprocal friendships is a challenge for many individuals with autism spectrum disorder (ASD). Social interaction difficulties emerge early, persist throughout development, and have widespread functional impact. As such, interventions focused on social functioning are needed in early intervention programs. This two-part study…

Autistic adults are at risk of stress-related psychiatric disorders and reduced life quality due to social, cognitive, and perceptual challenges. Mental health interventions adapted to autistic adults are scarce. Acceptance and commitment therapy has preliminarily indicated health benefits in autistic adults, although it has not been robustly…

This study explores the home language practice (HLP) of Korean-American mothers with children who have developmental disabilities, including autism spectrum disorder. Data was collected from an online forum where these mothers discussed their experiences and decision-making processes following their child's diagnosis. Thematic analysis was…

This dissertation is composed of two manuscripts that study the early development of infants at an elevated likelihood of an autism spectrum disorder diagnosis (EL-ASD). In the first manuscript, the language profiles (i.e., receptive dominant, expressive dominant, balanced) and the predictors of the language profiles are examined in infants at…

Executive functions (EF) are a collection of cognitive domains governing task initiation, motor planning, attention, and goal-oriented action. Difficulties with EF have marked impacts on adaptive living skills, learning outcomes, and quality of life for people with cognitive and psychosocial disabilities, as well as the broader population. While…

Applied behavior analysis (ABA) interventions are delivered using a tiered-service model, in which supervisors with higher levels of experience, education, and certification oversee clinicians who provide direct intervention for individuals with Autism Spectrum Disorder (ASD). Despite the base of empirical support for ABA constructed over several…

This qualitative study represents the perspective of a parent of a twice-exceptional (2e) child with autism and giftedness through the cultural lens of neurodiversity. Twice-exceptional children are those who are gifted and have a co-existing disability (Assouline, Foley-Nicpon, & Huber, 2006). This study used an autoethnography methodology,…

Purpose: Elementary-aged peers often need support for them to have positive interactions with classmates with autism who are minimally speaking (i.e., fewer than 30 functional spoken words). This study examined whether peers could learn to use responsive interaction strategies to support inclusive play and communication within a peer network…

This study used longitudinal special education record data from a large urban southwestern U.S. school district to review classroom placements of students in Grades 5 to 9 educated in traditional public schools (N = 21,314). Results indicated that half of the students were educated primarily in general education classrooms (n = 10,658), 9% of…

Background: "Remaking Recess (RR)" is a school-based evidence-based peer social engagement intervention for autistic students. RR involves direct training and coaching with educators; however, educators face several barriers to implementation at both the individual- and organizational-levels. This protocol paper describes a multi-site…

This study illustrates the potential offered by observational methodology for analysing spontaneous behaviours and interactions by students with autism spectrum disorder (ASD). We present a case study in which we observed, analysed and interpreted how an adolescent boy with ASD interacted both verbally and non-verbally with his physical education…

There are many different teaching technologies for neurotypical students, but students with autism spectrum disorders (ASD) may require online education media and Computer Based Interventions (CBIs) to thrive. For the purposes of this study CBIs are defined as a set of assistive interventions and technologies that are large and diverse based…

The present study investigated the perceptions of K-12 related service professionals and higher education disability service professionals about the need for postsecondary transition planning and strategies for students with Autism Spectrum Disorder (ASD). Twenty-two female participants participated in the study. The K-12 participants are…

There has been an increase in the number of students with high functioning autism who are mainstreamed and would, therefore be entitled to mandated counseling services (AFIRM, 2019). On the Individuals with Disabilities Education Act (IDEA) website, there are several evidence-based interventions that are listed for students with autism. One of…

Students with extensive support needs (ESN) are a heterogenous group of students with the most pervasive and ongoing support needs who typically receive special education services under the categories of autism spectrum disorder (ASD), intellectual disability, or multiple disabilities and often qualify to take their state's alternate assessment…
