Hospital Provider Knowledge Of Behavioral Function And Management Of Severe Behavior For Patients With Autism, Giovanna Salvatore Devito May 2024

Hospital Provider Knowledge Of Behavioral Function And Management Of Severe Behavior For Patients With Autism, Giovanna Salvatore Devito

Theses and Dissertations

Hospital patients with autism spectrum disorder (ASD) may engage in various topographies of severe behavior, with higher rates of restraint implemented than for their neurotypical counterparts. Qualitative research suggests that physician knowledge of function-based intervention is limited. Multidisciplinary behavior management teams were developed to decrease restraint across general hospital patients. In Study 1, the research team developed the Knowledge of Behavioral Function (KoBF) survey measure, using an iterative user-centered development process and administered the measure to multidisciplinary physicians and trainees. Results indicated low knowledge of behavioral function, with a mean percent correct of 66.60% on close-ended survey items and 14% …

Trauma-Informed Mindfulness-Based Stress Reduction To Increase Family Quality Of Life For Mothers Of Children With Autism: A Pilot Study, Carol May Vaughn

Theses and Dissertations

Mothers of children with autism have a higher rate of stress than mothers of neurotypical children and mothers of children with other disabilities. This impacts their family quality of life. This study aimed to show that by teaching mothers trauma-informed mindfulness-based stress reduction techniques they were able to switch their perspectives and feel that they had increased the relationships with their child with autism and increased the rating they give their family quality of life. The participants were recruited using word of mouth and through distribution of posters to autism communities following approval of the experiment through the institutional review …


Prosodic Speech Rate, Utterance Duration, Interruption Rate, And Turn-Taking Latency In Autistic And Neurotypical Adults, Grace Madeline Bell Mar 2024

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 Dec 2023

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 …

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 …


Understanding Gender Identification Within Individuals With Autism Using The Bem Sex-Role Inventory, Zackery Alan Cusworth Aug 2023

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 …


Behavioral And Eye-Movement Correlates Of Item-Specific And Relational Memory In Autism, Greta Nicole Minor Aug 2023

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 Aug 2023

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 …


Parent Facilitation Of Child Emotion Regulation In Autism Spectrum Disorder, Aimee K. Rovane Jul 2023

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 …


The Effects Of A Peer-Mediated Social Skills Intervention On Children With Autism Spectrum Disorder, Shannon Elizabeth Mcconaghie Jun 2023

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, …


Pivotal Response Treatment To Decrease Challenging Behavior And Increase Functional Communication In Preschool Children With Developmental Delays, Kalie Alexandra Gilmour Jun 2023

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 …


Behavioral And Physiologic Relationships Between Sensory Processing, Attention, And Prediction In Autistic Children: An Eye Tracking Study, Courtney Hunter Jun 2023

Behavioral And Physiologic Relationships Between Sensory Processing, Attention, And Prediction In Autistic Children: An Eye Tracking Study, Courtney Hunter

Theses and Dissertations

Autism spectrum disorder (ASD) prevalence has risen to one out of every 36 children born in the United States being diagnosed. Many individuals diagnosed experience sensory processing difficulties that make life challenging for them and their caregivers. However, there is no clear consensus on why sensory processing issues occur. Previous research has linked attention function to atypical sensory processing. Our study aimed to understand potential underlying mechanisms and correlates of this relationship. We theorized that prediction is a key contributing factor to how attention and sensory processing interact. The purpose of this study was to examine the relationship between sensory …


Emotion, Sensory Processing, And Prosody In Neurotypical And Autistic Young Adults, Annika Henderson Jun 2023

Emotion, Sensory Processing, And Prosody In Neurotypical And Autistic Young Adults, Annika Henderson

Theses and Dissertations

There is a paucity of research regarding autistic adults, yet as autistic individuals grow to adulthood, they are often met with several barriers because of their differences from the neurotypical (NT) population. Given the demands of adult social interaction, some of the social difficulties experienced by autistic adults are likely related to emotion processing and prosody function. With sensory processing differences added as a diagnostic criterion for autism within the last decade, an investigation into its relationship with emotional processing, another marked difficulty for this population, is warranted. There are logical connections between sensory processing, emotion, and prosody, such that …


A Longitudinal Look: How Sleep Impacts Suicidal Thoughts And Behaviors In Autism And Social Anxiety, Lindsay Jacalyn Regehr Apr 2023

A Longitudinal Look: How Sleep Impacts Suicidal Thoughts And Behaviors In Autism And Social Anxiety, Lindsay Jacalyn Regehr

Theses and Dissertations

Crucial research about suicidal thoughts and behaviors is often done in a cross-sectional manner that only considers limited risk factors. This research is limited in scope and rarely produces meaningful results to inform treatment. This study uses a longitudinal design to follow 93 participants over approximately 6 months. Participants are individuals with autism and social anxiety who were part of high-risk groups for suicidality, sleep problems, and social isolation. Participants recorded their sleep patterns and suicidal thoughts daily via the phone app MetricWire and continuously wore a GENEActiv actigraphy device to tract their objective sleep patterns. The Columbia Suicide Severity …


Behavioral Skills Training For Reducing Challenging Behaviors In Students With Down Syndrome With Or Without Co-Occurring Autism Spectrum Disorder, Jacqueline Tudor Jan 2023

Behavioral Skills Training For Reducing Challenging Behaviors In Students With Down Syndrome With Or Without Co-Occurring Autism Spectrum Disorder, Jacqueline Tudor

Theses and Dissertations

This applied dissertation was designed to improve the effectiveness of professional educators in using the methodology of functional behavior assessment (FBA) and function assessment-based intervention (FABI) to reduce challenging behaviors exhibited by students with Down syndrome (DS), or a dual diagnosis of Down syndrome and autism spectrum disorder (DS-ASD). Educators often rely on traditional classroom management methods which curtail disruptive behaviors without determining the reason why the behavior is occurring. The study examined the effects of utilizing a behavioral skills training program of instruction, modeling, rehearsal, and feedback in the methodology of FBA and FABI.

The research was conducted using …


Evaluating The Effects Of Video Modeling And Visual Supports On Preschoolers’ Compliance With Dental Procedures, Karly L. Orsi-Cordova Jan 2023

Evaluating The Effects Of Video Modeling And Visual Supports On Preschoolers’ Compliance With Dental Procedures, Karly L. Orsi-Cordova

Theses and Dissertations

Individuals with autism are reported to visit the dentist infrequently. Infrequent visits to the dentist may result in a higher occurrence of caries, and it is, therefore, imperative for children with autism to visit a pediatric dental practice routinely. Some basic behaviormanagement techniques, such as live modeling and reinforcement strategies, have been used with patients with autism. The addition of techniques derived from applied behavior analysis, such as video modeling and visual supports, may increase patients’ compliance with dental procedures. Specifically, the use of visual supports and video modeling warranted further investigation on the efficacy of improving behavior during dental …


The Congruence Of Parent-Teacher Relationships For Students With Autism: The Role Of Teacher Efficacy And School Climate, Morgan Johnson Sep 2022

The Congruence Of Parent-Teacher Relationships For Students With Autism: The Role Of Teacher Efficacy And School Climate, Morgan Johnson

Theses and Dissertations

Ecological Systems Theory (Bronfenbrenner, 1979) can be used as a framework to examine the importance of communication and collaboration among parents and teachers as both are important stakeholders in the field of education. Parent-teacher relationships are critical for autistic students particularly due to individualized education plans and the provision of special education services (IDEA, 2004). The current study examined relationships between parent-teacher dyads in terms of congruence, the degree to which both parties are in agreement about their relationship. This study was unique in its mixed methods design, combining quantitative and qualitative data, as well as its use of dyadic …


Perspectives Of Students With Asd And Their Parents: What Does It Truly Mean To Be Included?, Keara M. Browne Aug 2022

Perspectives Of Students With Asd And Their Parents: What Does It Truly Mean To Be Included?, Keara M. Browne

Theses and Dissertations

Though there are a number of practices identified by researchers and other professionals as inclusive, the question remains about whether the students themselves truly feel included. There has been limited research surrounding specific experiences in inclusive classrooms that students with autism spectrum disorder (ASD) perceive to be facilitators and barriers to being included in general education and co-teaching settings. The purpose of this study was to inform educational policies and school practices surrounding the inclusion of students with ASD in general education and co-teaching settings by analyzing the perceptions of students with ASD and their parents to determine what it …


Daily Survey Of Negative Affect And Social Interactions In Young Adults With High Levels Of Social Stress, Danica L. Limon Aug 2022

Daily Survey Of Negative Affect And Social Interactions In Young Adults With High Levels Of Social Stress, Danica L. Limon

Theses and Dissertations

Background: Few studies have focused on the contextual influences that impact negative affect (NA) and risk for mood disorders in young adults. Research using ecological momentary assessment (EMA) methods has shown that neurotypical adults with elevated social anxiety may be more sensitive to their social environment. To date, little is known about how types of social interactions impact autistic adults, who may show varying levels of social anxiety and social motivation. Aim: Our goal was to examine the heterogeneity in daily social experiences for autistic and socially anxious adults. Method: Using EMA surveys, we tracked daily self-reported face-to-face interactions and …


The Acceptability And Feasibility Of Virtual Parent Acceptance And Commitment Therapy Groups: A Feasibility Study, Abigail Elizabeth Moretti Aug 2022

The Acceptability And Feasibility Of Virtual Parent Acceptance And Commitment Therapy Groups: A Feasibility Study, Abigail Elizabeth Moretti

Theses and Dissertations

Parents of children with autism spectrum disorder (ASD) experience higher rates of anxiety, depression, and poor overall well-being, particularly when their child also engages in challenging behavior (e.g., self-injury, aggression, property destruction). Acceptance and commitment therapy (ACT), which encourages psychological flexibility and attending to the present moment, is particularly suited for this population because parents of children with ASD experience high stress levels and difficulty with adaptive coping. The aim of the current study is to examine the feasibility and acceptability of implementing virtual ACT groups with parents of children with ASD and co-occurring challenging behavior. Participants attended an in-person …


The Effects Of Presession Conditions On Behavior During A Brief Functional Analysis, Dung Haylie Le Jul 2022

The Effects Of Presession Conditions On Behavior During A Brief Functional Analysis, Dung Haylie Le

Theses and Dissertations

Previous research has demonstrated that patterns of responding during a no-interaction condition of a functional analysis (FA) may predict FA outcomes. Thus, behavior analysts may use an initial no-interaction condition to identify problem behavior maintained by social reinforcement when time and resources are limited. However, in a clinic setting, most functional analyses are conducted in between or immediately after instructional sessions or structured play. Therefore, the proposed study was designed to examine the differential effects of presession conditions of naturally occurring activities (work versus play) at a clinic setting during a modified brief functional analysis. Results showed that presession conditions …


Teaching Children With Autism To Tact Private Events Based On Common Properties, Madisyn Quidort Jul 2022

Teaching Children With Autism To Tact Private Events Based On Common Properties, Madisyn Quidort

Theses and Dissertations

Skinner (1957) proposed that people learn to talk about private events in several ways. This study sought to examine the plausibility of one of those mechanisms: common properties. Skinner asserted that children learn tacts for public stimuli through normal interaction with their caregivers. When a child experiences a private stimulus that shares some feature with a previously learned public stimulus, the child generalizes the tact to the private sensation because there is a common property between the two stimuli. Three children with autistic disorder were taught 6 to 9 sensation tacts (e.g., prickly, cozy, tight) depicted in videos (e.g., a …


Intolerance Of Uncertainty, Sensory Processing, And Related Correlates In Autistic Children During The Covid-19 Pandemic, Mollie Bradley Jun 2022

Intolerance Of Uncertainty, Sensory Processing, And Related Correlates In Autistic Children During The Covid-19 Pandemic, Mollie Bradley

Theses and Dissertations

The COVID-19 pandemic increased uncertainty and anxiety for most and was especially disruptive to autistic people and their families. Autistic children were particularly vulnerable due to their intolerance for increased uncertainty and disruption to their school and therapy support. This study aimed to investigate the effect that increased uncertainty had on autistic children, specifically their sensory behaviors and stress levels and on the stress levels of their primary caregivers. Parents and guardians of 47 autistic children completed an online survey consisting of questions investigating background and demographic information, their experiences during the first six months of the pandemic, information about …


Needs Assessment Of Services Provided In A Rural School District For Students With Autism, Danielle Anne Katterman Jun 2022

Needs Assessment Of Services Provided In A Rural School District For Students With Autism, Danielle Anne Katterman

Theses and Dissertations

The number of children diagnosed with autism spectrum disorder (autism) has steadily increased dramatically over the past generation, and more students with autism than ever before are enrolled in the public education system. Educating students with autism presents unique challenges (e.g., shortage of staff, low incidence of autism, limited programming) to rural school districts. Rural districts must adhere to the same federal and state guidelines (e.g., Individuals with Disabilities Education Act & Free and Appropriate Public Education) as urban districts that have more readily available resources in providing appropriate programming. This study examined stakeholders' perceptions of the current services offered …


Comparing The Effects Of Online And In-Person Social Skills Training For Adolescents With Autism Using Peers®, Benjamin Tze Ming Ooi Jun 2022

Comparing The Effects Of Online And In-Person Social Skills Training For Adolescents With Autism Using Peers®, Benjamin Tze Ming Ooi

Theses and Dissertations

Autism Spectrum Disorder (autism) is a neurodevelopmental disorder characterized by social skills differences which can interfere with success in developing or maintaining relationships. Social skills training may promote more satisfying change in social interactions for individuals with autism, especially if they already have age-appropriate cognitive and language abilities. Social skills training is a typical approach for addressing social skills needs for many individuals with autism. In some instances, in-person social skills training or groups may not be readily available because of geographical, transportation, or other barriers. Delivering social skills training online is one way to increase access to intervention for …


The Behavioral And Neurophysiologic Relationships Between Sensory Processing And Autistic Traits In Emerging Adults, Savanah Calton Jun 2022

The Behavioral And Neurophysiologic Relationships Between Sensory Processing And Autistic Traits In Emerging Adults, Savanah Calton

Theses and Dissertations

The majority of individuals diagnosed with Autism Spectrum Disorder (ASD) experience sensory processing difficulties that are also associated with greater presence of autistic traits, psychiatric difficulty, and intolerance of uncertainty (IU). These relationships are also expressed in the neurotypical (NT) population, termed the Broader Autism Phenotype (BAP), and present with impacts to daily functioning/well-being just as prominently. However, little is known concerning the neurophysiologic nature of these behavioral relationships, especially in young adults. Thus, the purpose of the current study was to examine the behavioral and neurophysiologic nature of the relationships between sensory processing, autistic traits, and related behavioral functions …


Auditory Brainstem Response In Autistic Children: Potential Implications For Sensory Processing, Madelyn Cate Jun 2022

Auditory Brainstem Response In Autistic Children: Potential Implications For Sensory Processing, Madelyn Cate

Theses and Dissertations

Autistic people frequently experience sensory processing difficulties. For many on the autism spectrum, such difficulties can significantly impact important functions and quality of life. We are only beginning to understand the neural mechanisms of atypical sensory processing. However, one established way to measure certain levels of auditory processing is with auditory brainstem responses (ABR). While ABR has been primarily hypothesized in the current literature as a means of early detection/diagnosis in autism, additional research is needed to determine the ABR’s utility in examining sensory processing in this population. Thus, we evaluated ABR in 19 young children with autism during various …


The Default Network And Autism Spectrum Disorder: Characterizing Sub-Networks And Behavioral Correlates, Alyssa K. Kozlowski Jun 2022

The Default Network And Autism Spectrum Disorder: Characterizing Sub-Networks And Behavioral Correlates, Alyssa K. Kozlowski

Theses and Dissertations

The default network (DN), and specifically its sub-networks default network A (DN A) and default network B (DN B), has been strongly implicated in social cognition. This study examined its role in predicting social behavior, and also differences that may exist across diagnostic groups that may explain discrepancies in social cognition and behavior. One of the popular methods of study is functional connectivity, or analyzing correlated activity in the brain. Autism Spectrum Disorder (ASD) is a disorder characterized by social impairment and abnormal social behavior. To date, much of the functional connectivity research in ASD has focused on global connectivity, …


Predictors Of Emotional Health Across Autistic And Non-Autistic Students' First Semester Of College, Erin E. Mckenney May 2022

Predictors Of Emotional Health Across Autistic And Non-Autistic Students' First Semester Of College, Erin E. Mckenney

Theses and Dissertations

The prevention and treatment of mental health concerns, including depression, are significant priorities for autistic adults. While several theories have been proposed to explain the high prevalence of depression in autistic populations, little longitudinal research has been done on potential causal mechanisms. Additional research is needed to explore how proposed contributors to depression from general population research -- namely, negative repetitive thinking, lack of social opportunity, and attributional style -- predict and/or moderate the development of depressive symptoms in autistic individuals. The current study investigates these potential predictors' relationship to internalizing symptoms over the course of college students' first semester. …
