Methods: A systematic search was conducted across multiple electronic databases, including PubMed, Scopus, and PsycINFO following PRISMA guidelines. Studies reporting on early detection methods for ASD in infants and toddlers within ages 0 to 3 years that lead to early diagnosis of children ages 2 to 3 years were eligible for inclusion. Data extraction and quality assessment were …

Evaluating A Video Peer-Modeling Intervention On The Acquisition And Maintenance Of Social Skills For Adults With Autism In A Transition Setting, Adam K. Hammond

Theses and Dissertations

This study evaluated the use of a peer video modeling and prompting intervention used to teach three adults with autism to give a specified verbal and physical response when greeted. This intervention used a six-step task analysis to verify correct completion of the target behavior. At baseline, each of the three participants gave little to no response when greeted but after the video modeling and prompting intervention all three had acquired at least five out of six (83%) of the target behavior steps. Follow-up probes demonstrated that all three of the participants had maintained at least 4 out of 6 …

Supporting Social Development In Students With Disabilities, Elyzabeth Andersen

Capstone Projects and Master's Theses

This capstone project focused on the social development of kindergarten students receiving special education services who spend a portion of their day in inclusive placements. The number of students receiving special education services in inclusive classroom environments has increased over time. However, special education students often experience social isolation, lack reciprocal friendships, and have limited interactions with peers without disabilities, even in inclusive settings (Avramidis et al., 2018; Koster et al., 2010). Therefore, there is a need to encourage positive interactions between peers with and without disabilities. To address this need, I developed a set of three lessons for special …

Increasing Emotional Regulation In Young Children With Autism Spectrum Disorder, Bryana Arias

Capstone Projects and Master's Theses

This capstone project focuses on the emotion regulation skills of school-age children (5 to 7 years) on the moderate to severe autism spectrum. Emotional regulation is the process by which a person engages in behaviors with the implicit or explicit goal of altering emotion frequency, intensity, duration, or type (Raugh & Strauss, 2023). Through emotional self-regulation, individuals can control their thoughts, behaviors, and emotions within everyday situations. This process involves the ability to identify one’s emotions and those of other people while developing strategies to constructively manage their reactions to emotional experiences and inhibitory control (Dumont et al., 2019). Autism …

Prosodic Pitch And Intensity In Autistic Individuals, Cassidy Gooch

Theses and Dissertations

This study is an examination of how prosodic pitch and intensity compare in autistic individuals and neurotypical individuals. Ten-minute recordings of casual conversation were taken and analyzed. Participants included 11 autistic individuals and 11 neurotypical individuals with six males and five females in each group. The Autism Diagnostic Observation Schedule, 2nd Edition (ADOS-2; Lord et al., 2012) prosody rating scale was used to collect a perceptual evaluation of each participan's prosody, and Praat acoustic analysis software was used to collect measures of pitch and intensity over the 10-minute period to investigate how speech characteristics change with conversation partner familiarity. Results …

Internalizing Symptoms In Autistic Young Adults: Comparing The Cognitive And Physiological Components Of Emotion Regulation, Sarah Lehman

Master's Theses (2009 -)

Autistic people experience co-occurring mental illness at a substantially greater rate compared to their neurotypical counterparts. Of these comorbid psychopathologies, internalizing disorders (anxiety and depression) are among the most prevalent. Emotion dysregulation has been identified as a contributing factor to this phenomenon and potential treatment target. The current study employed cognitive (e.g., use of suppression and use of cognitive reappraisal) and physiological (e.g., respiratory sinus arrhythmia (RSA) and heart period) measures to more holistically capture the multifaceted construct of emotion regulation compared to prior research. In a sample of autistic young adults (N = 63) ages 17-29 (M = 20.14), …

Estimating Hemispheric Specialization In Autistic And Neurotypical Individuals, Madeline Peterson

Theses and Dissertations

While the brain appears to be symmetrical, macroscopic differences or asymmetries between the two hemispheres emerge through careful quantitative study. Functional asymmetries can accompany these structural asymmetries, and these can be a reflection of hemispheric specialization, or the predominant hosting of macroscale functional network and its accompanying functional properties by a given hemisphere. Prior work has identified the specialization of language to the left hemisphere, visuospatial attention to the right hemisphere, and a dual specialization of executive control to both hemispheres. However, it is largely unknown how specialization is characterized at an individual level, particularly in terms of identifying the …

Investigating Neural Mechanisms Associated With The Double Empathy Problem Using Fnirs Hyperscanning, Kate E. Turner

Electronic Thesis and Dissertation Repository

The Double Empathy Problem posits that autistic social difficulties are due to differences in communication styles rather than an autistic deficit in theory of mind (ToM). We used fNIRS hyperscanning to examine whether neural synchrony in pairs with varying levels of autistic traits during social interactions supports the Double Empathy Problem. Participants with low and high autistic trait expression were paired creating High-High, Low-High, and Low-Low groups. Pairs completed two trials where they 1) listened to and 2) discussed stories that contained or lacked theory of mind elements, while brain activity was recorded within the ToM network. During conversation, High-High …

Understanding Gender Identification Within Individuals With Autism Using The Bem Sex-Role Inventory, Zackery Alan Cusworth

Theses and Dissertations

Gender is a socially derived construct that is taught and understood at young ages. However, not every individual has the same social skills to understand these seen and unseen social cues about gender. The Bem Sex-Role Inventory was given to adult individuals with autism in the United States to better understand their masculine, feminine, and androgenous perceptions. These data were then compared to the original Bem Sex-Role Inventory general population study to see if there were any differences. The data show that males with autism had lower masculine scores and higher feminine scores than males in the general population. Females …

Coaching In Differential Attention And Pride Skills During Child Directed Interactions For Siblings Of Children With Neurodevelopmental Disorders, Ava Sardoni

Dissertations, 2020-current

Neurodevelopmental Disorders (NDDs) are an increasingly-common presentation that is often associated with significant behavioral and relational challenges. NDDs can impact multiple areas of functioning including social, academic, and adaptive functioning. As NDDs are developmental disorders in nature, they are often lifelong conditions that require intensive treatments and adaptations throughout the lifespan. One of the most important predictors of success and fulfillment for a child with an NDD is the support from the family system.

Siblings of a child with an NDD are often neglected from the conversation of supports and treatments for children with NDDs. However, challenging behaviors often associated …

Teaching Peer Imitation To Preschool-Aged Children With Autism Spectrum Disorder Using A Video Modeling Treatment Package, Megan M. Harper

Theses & Dissertations

Peer imitation is a skill that serves to promote the acquisition of new play skills, problem-solving skills, and academic skills through observation of one’s peers. Although peer imitation is an important pre-requisite for learning from peers, many autistic children experience deficits in this area. In the present study, we evaluated a video model treatment package to teach autistic children to imitate their peers. Additionally, we conducted free play probes pre- and post-training to assess the transfer of training to a natural play setting. The results of the current study are mixed. One participant’s imitation skills generalized to the in-vivo sessions …

Increasing Exercise In Individuals With Autism Spectrum Disorder: A Systematic Review Of Instructional Strategies, Jacob Moak

Seton Hall University Dissertations and Theses (ETDs)

It has been found that children with autism spectrum disorder (ASD) are 1.6 times more likely to be obese compared to neurotypically developing children. Individuals with ASD often struggle with motor skills and experience sensory processing difficulties, which can make it difficult to participate in regular physical activity. Because of this, it is crucial to find exercise methods that are enjoyable, practical and that are tailored to the specific needs of individuals with ASD in order to help them maintain a healthy lifestyle. The current systematic review investigated the research literature on interventions used to teach exercise to individuals with …

The Impact Of The Social Story Intervention On Children With Autism Spectrum Disorder (Asd) In Saudi Arabia, Marwan Alkhudhayri

Electronic Theses and Dissertations

Autism Spectrum Disorder (ASD) is on the rise in Saudi Arabia, and the field of Special Education is currently working to expand awareness about ASD as well as evidence-based intervention availability in the country. The Social Stories Intervention has been shown to have positive results in work with children with ASD in other countries, however its effectiveness in Saudi Arabia had not thoroughly been examined. The Social Stories Intervention provides an important tool for practitioners to use with children with ASD in order to help improve their social skills development. The current study utilizes a single-subject design to assess the …

Behavioral And Eye-Movement Correlates Of Item-Specific And Relational Memory In Autism, Greta Nicole Minor

Theses and Dissertations

Recent work has challenged past findings that documented relational memory impairments in autism. Previous studies have often relied solely on explicit behavioral responses to assess relational memory integrity, but successful performance on behavioral tasks may rely on other cognitive abilities (e.g., executive functioning) that are impaired in some autistic individuals. Eye-tracking tasks do not require explicit behavioral responses, and, further, eye movements provide an indirect measure of memory. The current study examined whether memory-specific viewing patterns toward scenes differ between autistic and non-autistic individuals. Using a long-term memory paradigm that equated for complexity between item and relational memory tasks, participants …

Exploring Levels Of Autism Symptom Support After Eligibility Determinations, Zachary Bella

Theses and Dissertations

The identification of autism spectrum disorders (ASD) occurs in educational and health settings. Many children with autism will only receive a classification of autism in the educational setting (Esler et al., 2022, Pettygrove et al., 2013, Wiggins et al., 2020). There is significant overlap between the early intervention offered to children with autism in health settings and what is provided through Individualized Education Programs (IEPs) (National Autism Center, 2009; Morset et al., 2010). However, there is an increasing trend of children with autism being classified with significant developmental delay (SDD) instead of autism initially in schools and the impact of …

African-American Parents’ Cultural Understandings Of The Concept Of Autism And Implications For Parental Communication And Health Management, Kellie J. Fennell

Communication & Theatre Arts Theses

In 2023 the Centers of Disease Control reported that around 1 in 36 children are diagnosed with Autism in America and that the prevalence has increased by 178% since 2000 (CDC, 2023). Despite increases in awareness and diagnosis past research finds that the discussions of ASD in African American communities is minimal (Fombonne, 2003; Yeargin Allsopp et al., 2003). This disparity is important considering that African American children receive an ASD diagnosis years later than their white counterparts and are much more likely to be misdiagnosed (Mandell et al., 2009, 2002).

Given the history of a lack of representation of …

Using Linked Digital Activity Schedules To Promote Cooperative Thematic Play, Vincent E. Campbell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Previous research has shown that children with autism spectrum disorder (ASD) may struggle to engage in social play, which may impact their willingness to engage in contextually appropriate cooperative play (Koegel et al., 2014). Researchers suggest that activity schedules targeting cooperative play may increase appropriate play for children with ASD (Brodhead et al.,2014; Pellegrino, 2018). However, previous studies did not include opportunities for interactive choice responding or the implementation of generic picture cues during script training. We investigated the impact of a linked digital activity schedule on promoting cooperative thematic play in children with ASD. Six children with ASD engaged …

Executive Functioning In Children With Autism And Co-Occurring Neurodevelopmental Disorders: A Systematic Review And Quantitative Analysis, Kandice Benallie

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Children with autism and other NDDs experience some level of executive dysfunction including challenges with problem-solving, judgement, working memory, and flexibility. Considering autism and other NDDs including ADHD and ID have overlapping symptoms, it can be difficult to differentially diagnose the disorders. This dissertation sought to explore how co-occurring ADHD and ID impact the EF of autistic children. The first study systematically reviewed the current research examining EF of autistic children with co-occurring ADHD and ID. Findings suggest that co-occurring ADHD and ID result in increased executive dysfunction as compared to children with autism only. The systematic review also revealed …

App-Based Academic Interventions For Children With Autism, Cassity R. Haverkamp

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Technology, such as tablet/phone apps, robots, video games, and virtual reality, can be used to teach skills to autistic children. Research on technology supports for autistic youth often focus on social skills, a main part of an autism diagnosis. However, autistic children may also have academic challenges, and fewer studies have looked at how technology can teach academic skills to children with autism. We created three studies to look at how academic apps may benefit autistic children. In the first study, we reviewed studies that looked at how academic apps can increase the academic skills of children with autism. We …

Commonalities In Evidence-Based Instructional Strategies For Autism Spectrum Disorder And English Language Learners, Kimberly Michelle O'Mara

Graduate Theses and Dissertations

Many English language learners experience life on the Autism spectrum. These students will spend much of their day in the general education setting, and teachers will need effective and proven strategies to support them. The data show that Autism Spectrum Disorder is increasing among all populations (CDC, 2023). Current understandings and influences on these learners will be explored. This review examines evidence-based practices presented by premier sources in the fields of Autism Spectrum Disorder and English language learning, seeking commonalities in strategies. Using the findings from the National Standards Report and the National Clearinghouse for Autism Evidence & Practice cross-referenced …

Neurodiverse Perceptions Of Inclusivity In The Workplace, Shannon Lively

Dissertations

The increase in neurodivergent professionals in the workplace has led to a significant need for researchers to examine neurodiversity inclusion in the workplace. Research has portrayed workplace inclusion as the perception that the individual is a valued member of a workgroup through satisfactory experiences of belongingness and uniqueness. Through semi-structured interviews with 20 neurodivergent professionals, this study examined how they view inclusion, exclusion, and cope with exclusion in the workplace. The neurodivergent participants identified six inclusion and six exclusion categories. Results were largely consistent with previous inclusion research, however, one novel category, flexible accommodations, suggests the importance of considerate accommodations …

Autism, Comorbidities, And Adaptive Functioning: A Potential Moderator, Joshua J. Montrenes

LSU Doctoral Dissertations

Deficits in adaptive functioning and the presence of comorbid symptomatology are both commonly associated with autism spectrum disorder (ASD). Previous research has identified relationships between functional level (e.g., intellectual quotient [IQ], adaptive functioning [AF]) and comorbid symptomatology in ASD. However, further insight into the relationship between AF, comorbid psychopathology, and ASD is unclear. Specifically, how AF affects the relationship between ASD and comorbid conditions is not well understood. Whether AF moderates the relationship between autism symptom severity and comorbid symptom severity in toddlers with ASD was examined. ASD symptom severity positively correlated with comorbid symptom severity across domains and negatively …

Parent Facilitation Of Child Emotion Regulation In Autism Spectrum Disorder, Aimee K. Rovane

Theses and Dissertations

Parents play a substantial role in their children's emotional regulation (ER) abilities, promoting both adaptive and maladaptive development. Children with autism spectrum disorder (ASD) often have difficulties regulating their emotions, manifesting in externalizing behavioral issues (Mazefsky & White 2014). Though there are many similarities to parents of typically developing (TD) children, parents of children with ASD facilitate their children's ER development (i.e., emotion socialization) in response to unique challenges, often developing resiliency but other times contributing to their children’s dysregulation and behavioral challenges. Using Morris et al.'s (2007) Tripartite Model of Family Impact of Children's Emotion Regulation and Adjustment as …

Ally Mediation Of Social Media Use For Adults With Autism, Spring S. Cullen

Theses and Dissertations

Previous research has highlighted the unique challenges young Autistic adults face when using social media. We extend this work by analyzing how guardians and allies, such as service providers, mediate the social media usage of young Autistic adults in order to address and mitigate online risks. Based on analysis of interview transcripts (8 young adults on the Autism spectrum, 4 parents, 10 staff members), we uncover the mediation tactics used, how they differ based on the ally's relationship with the individual, and the tactics' varying degrees of effectiveness. The findings of this research contribute to the literature by informing the …

Pivotal Response Treatment To Decrease Challenging Behavior And Increase Functional Communication In Preschool Children With Developmental Delays, Kalie Alexandra Gilmour

Theses and Dissertations

After a review of the literature on Pivotal Response Treatment (PRT) in young children with developmental delays, less was known on its effects on challenging behavior and functional communication in preschool age children receiving services in a traditional public school. A multiple baseline design across three participants was used to evaluate the effects of PRT on the functional communication of three preschool students with developmental delays. Based on a functional analysis, we also observed the effects of PRT on challenging behavior. A visual analysis of the data revealed a functional relation between PRT and functional communication and provided promising evidence …

The Effects Of A Peer-Mediated Social Skills Intervention On Children With Autism Spectrum Disorder, Shannon Elizabeth Mcconaghie

Theses and Dissertations

The purpose of this study is to analyze the effects of a peer-mediated social skills intervention (PMI) on children 6-12 years of age diagnosed with autism spectrum disorder (ASD). Current literature discusses the effects of peer-mediated social skills interventions for children with ASD in schools and on the playground but has not been conducted in an Applied Behavior Analysis (ABA) clinic or in an Early Childhood Education/ABA-integrated preschool. Three dyads, each consisting of a typical peer and a target child diagnosed with ASD, participated in this study. The frequency of participants' initiations, responses, and continuations were collected throughout all phases, …

Exploration Of The Impact Of Gender-Affirming Care And Social Support On Executive Functioning And Mental Health In Gender-Diverse Autistic And Non-Autistic Adults, Karys Michaela Normansell-Mossa

Theses and Dissertations

Between 4.8% and 26% of adults presenting to gender dysphoria clinics have an autism diagnosis. Both autistic people and gender-diverse people have higher rates of mental health conditions including anxiety and depression and more difficulties with executive functioning, all of which impact quality of life. Some work suggests that gender affirmation leads to better mental health outcomes, including better executive functioning, but this has not been studied directly in autistic adults who identify as gender-diverse or transgender. As such, we elected to explore the relationships among these variables at this intersection of gender diversity and autism. In a sample of …

Family Member Experiences With Augmentative And Alternative Communication Systems Used By Nonspeaking Autistic Individuals, Christina M. Wotton

Doctor of Education Program Dissertations

Nonspeaking autistic individuals who have no way to communicate cannot share their thoughts, dreams, or desires. The purpose of this qualitative narrative inquiry was to explore the experiences of family members of nonspeaking autistic individuals who use augmentative and alternative communication (AAC) systems. This study documented family members’ experiences of identifying, learning, and implementing two types of AAC: Rapid Prompting Method and Spelling to Communicate. Through one-on-one interviews, five participants shared their lived experiences. Three themes emerged from the data. The first theme was an increase in well-being for the entire family. All five participants described transformations and improvements in …

Missed And Prior Diagnoses In Children Later Diagnosed With Autism, Maire Diemer

Dissertations

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, and intellectual disability) assigned to children who are later diagnosed with autism. The study investigates how race, sex, and geographic factors were associated with age of diagnosis and diagnostic load. This study utilized a sample of 13,850 children aged 2-10 who were diagnosed with autism on Missouri Medicaid between 2015 and …
