An Investigation Of How Previous Diagnoses Affect The Developmental Functioning Of Children At Risk For Autism Spectrum Disorder, Michaela Brown

LSU Master's Theses

Research has shown that children with autism spectrum disorder (ASD) often have co-occurring medical and/or psychiatric disorders. This current study aimed to investigate how previous diagnoses, which may become comorbidities of ASD if diagnosed, affect the developmental functioning of children presenting as at risk for ASD compared to those presenting with no risk. Developmental areas such as communication, motor, adaptive, cognitive and social, as well as overall developmental functioning, were considered in the analysis. 11,970 children under the age of three were studied. Results found that the presence of previous diagnoses significantly predicted developmental functioning, particularly in the motor functioning …

Developmental Functioning Of Infants And Toddlers With Neurodevelopmental Disorders, Megan Callahan

LSU Master's Theses

Autism spectrum disorder (ASD), epilepsy, and cerebral palsy (CP) are some of the most common neurodevelopmental disorders among children with prevalence rates of 1.85% (Maenner et al., 2020), 1.2% (Zack & Kobau, 2017), and between 0.21 and 0.31% (Christensen et al., 2013), respectively. These neurodevelopmental disorders are highly comorbid with each other and with other disorders, such as intellectual disability (ID). While previous research has investigated developmental functioning in these neurodevelopmental disorders, it has primarily focused on only two at a time and in older children or adults. The current study aimed to investigate developmental functioning in these neurodevelopmental disorders …

Do Black Girls Receive Later Developmental Disability Diagnoses?: Results From A National Study Of Children In The United States, Danequa Forrest

LSU Doctoral Dissertations

Abstract

This study sought to analyze if age at diagnosis of autism spectrum disorder, intellectual disability, and developmental delay varies by race and sex for children between ages 6 and 17 years old. I used data from the 2011 Survey of Pathways to Diagnosis and Services (“Pathways”), a follow-up survey to the 2009/10 National Survey of Children with Special Health Care Needs (NS-CSHCN). With this nationally representative dataset, I was able to perform ordinary least squares linear regression in Stata 13. Results determined that Black girls were diagnosed with autism spectrum disorder about two years later than White girls, nearly …

Factors Associated With Restricted, Repetitive Behaviors And Interests And Diagnostic Severity Level In Young Children With Autism Spectrum Disorder, Esther Hong

LSU Master's Theses

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by deficits in social communication and social interactions and the presence of restricted, repetitive patterns of behavior (RRBIs). The presence of RRBIs can be detrimental to a child’s development, as RRBIs can lead to impairments in other areas of functioning, impede learning, and contribute to parental stress. Previous studies have identified several factors that are associated with RRBI severity and topography. The current study aims to assess whether impairments in adaptive functioning predict RRBI severity, using the Vineland Adaptive Behavior Scales, Third Edition (VABS-3) and Baby and Infant Screen for Children …

Developmental Regression In Children With Autism Spectrum Disorder: Associated Factors And Outcomes, Jasper Abarte Estabillo

LSU Doctoral Dissertations

Autism spectrum disorder (ASD) is an increasingly common neurodevelopmental disorder characterized by deficits in socialization skills and the presence of restricted and repetitive behaviors. In addition to a number of medical and psychological comorbidities, ASD is associated with a complex phenomenon: developmental regression (i.e., loss of skills in developmental domains). Although present in other disorders (albeit rare), developmental regression is prevalent among individuals with ASD. Thus, interest in studying the phenomenon has grown. However, research on associated risk factors and outcomes is limited and findings have been inconsistent. The current study had two aims: (1) examine potential factors associated with …

Rule-Governed Behavior: Teaching Essential School Readiness Skills Via Rule-Following To Children With Autism, Rachel Lorraine Bradley

LSU Doctoral Dissertations

Rule-governed behavior (RGB) is behavior that is controlled by verbal descriptions of contingencies rather than by direct contact or a history of direct contact with the contingencies. Humans rely on RGB to navigate a multitude of life experiences, and in doing so, we avoid direct contact with destructive or harmful contingencies or contingencies that would be inefficient to contact. However, individuals with autism spectrum disorders (ASD) do not naturally demonstrate RGB, leaving them at increased risk of contacting dangerous consequences. Thus, acquiring RGB is a critical concern that affects the development and wellbeing of individuals with ASD. The current study …

Factors Related To Parental Stress At Early Diagnostic Assessments For Autism Spectrum Disorder, Abigail Issarraras

LSU Master's Theses

Autism Spectrum Disorder (ASD) is marked by pervasive impairments in social communication and restricted, repetitive interests, behaviors, and activities. Parents raising a child with ASD have consistently reported higher levels of parenting stress compared to parents of typically developing children and children with other disabilities. Several different factors influence parental stress levels at different stages of their child’s life, and so an understanding of the most predictive factors of parental stress at initial ASD assessments is critical to best serving the needs of families with a new diagnosis. The current study investigated several factors that may impact parenting stress at …

Examining The Sex Ratio In Autism Spectrum Disorder, Maya N. Matheis

LSU Doctoral Dissertations

The higher prevalence of autism spectrum disorder (ASD) among males compared to females is well documented but poorly understood. The ASD sex ratio may provide valuable insight into the underlying neurobiological mechanisms of the disorder. A review of studies examining the prevalence in ASD published in the last 5 years was conducted, revealing a mean male/female (M/F) ratio of 4. Literature examining the ASD sex ratio in relation to risk factors and associated features of ASD was also summarized. The study aimed to examine the ASD sex ratio and its association to various risk factors among an early intervention sample. …

Predictors Of Graduate Students' Self-Efficacy For Working With Persons With Autism Spectrum Disorder And Their Families, Cassie M. Dinecola

LSU Doctoral Dissertations

As diagnoses of autism spectrum disorder (ASD) continue to climb, the need for knowledgeable and competent professionals is critical. Research has shown that child symptoms and behavior are related to parent stress and mental health and that this relationship is bidirectional, suggesting the need for the use of a family-centered care model (FCC) that addresses both child and parent needs. While social workers are well-prepared to provide FCC to persons with ASD and their families, few social workers enter the field of developmental disabilities. Professionals more involved in the ASD field, such as special educators, often are equipped to work …

An Investigation Of The Relationship Between Seizures And Autism Symptomology In Young Children, Claire O. Burns

LSU Master's Theses

Autism spectrum disorder (ASD) is a condition that consists of deficits in social communication as well as restricted, repetitive interests or behaviors. Individuals with ASD also often have comorbid psychiatric and medical disorders. One such concern is high rates of seizures and epilepsy. Researchers have found that rates of seizures tend to be higher in individuals with ASD who also have more impaired functioning. However, few studies have examined how the presence of seizures is related to symptoms of ASD. The current study aimed to expand the extant literature by investigating whether a history of seizures is associated with ASD …

An Examination Of Autism Symptomatology In Young Children With Family History Of Autism Spectrum Disorder, Jasper Abarte Estabillo

LSU Master's Theses

Multiple genetic and environmental factors have roles in the etiology of autism spectrum disorder (ASD). Thus, researchers have become increasingly interested in studying family members of individuals with ASD in order to examine possible risk factors and to identify early markers of the disorder. While family history of ASD may put an individual at risk for developing autism, there is limited research examining how the degree of relationship to the affected individual may be related to an individual’s presenting ASD symptomatology. Because closer familial relationships (i.e., first-degree relatives) have more shared genetic material and tend to have increased common environment …

The Contribution Of Comorbid Symptomology To The Social Skill Deficits In Infants And Toddlers With Autism Spectrum Disorder, Paige Elizabeth Cervantes

LSU Master's Theses

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by deficits in social communication and the presence of restricted and repetitive patterns of behavior or interests. The onset of ASD symptomology occurs prior to 30 months of age; however, typical diagnosis is made at 3 to 4 years old. Early identification of ASD is imperative for more effective treatment and a bettered prognosis. The evaluation and treatment of ASD is complicated by high rates of comorbid psychopathology. When an individual presents with ASD and a co-occurring disorder, symptoms may manifest differently. Utilizing the Baby and Infant Screen for Children with …

How Core Symptoms Of Autism Spectrum Disorder Predict Engagement In Specific Topographies Of Challenging Behavior, Sara Mahan

LSU Doctoral Dissertations

Challenging behavior, such as aggression, destructive behavior, and self-injurious behavior (SIB), are common among people of all ages with Autism Spectrum Disorder (ASD). Numerous researchers have found that greater severity of ASD or a diagnosis of ASD is significantly correlated with greater levels of challenging behavior. However, there is dearth of information on how core symptoms of ASD (i.e., socialization deficits, communication deficits, stereotypies) predict the engagement of specific topographies of challenging behavior above and beyond other variables, such as developmental functioning. The purpose of this study is to extend the current literature base through examining how core symptoms of …

The Emergence Of Challenging Behaviors In At-Risk Toddlers With And Without Autism Spectrum Disorder: A Cross-Sectional And Risk Factor Study, Jill Cherie Fodstad

LSU Doctoral Dissertations

Challenging behaviors including aggression, property destruction, stereotypy, and self injury occur at a high prevalence in individuals with Autism Spectrum Disorders (ASD). These behaviors are pervasive and chronic. Despite an increased probability and negative consequences, one area which has received little attention is the presence of challenging behaviors in infants and toddlers with ASD. Furthermore, there is a dearth of information identifying early age trends in the emergence of challenging behaviors and associated risk factors. The purpose of this investigation was to utilize a validated measure, the Baby and Infant Screen for Children with aUtIsm Traits - Part 3, to …

Differences Across Racial Groups In Caregiver Ratings Of Symptoms In Children Diagnosed With Autism Spectrum Disorders, Cindy Terlonge Graham

LSU Doctoral Dissertations

A great deal of attention from local, federal, and international communities has been focused on autism spectrum disorders (ASDs). As the prevalence of these disorders rise, researchers continue to investigate various unanswered questions. The goal of this study was to examine the differences across racial/ethnic groups in caregiver ratings of symptoms of children diagnosed with ASDs. Results from such research will help determine whether cultural background can influence the recognition of behaviors indicative of an ASD. Culturally-sensitive clinical practice stemming from the significant findings of this research project can help to reduce the age at which minority children are diagnosed. …

An Examination Of Challenging Behaviors In Autistic Disorder Versus Pervasive Developmental Disorder Not Otherwise Specified: Significant Differences And Gender Effects, Alison M. Kozlowski

LSU Master's Theses

Children with Autism Spectrum Disorders (ASDs) are well-known for engagement in challenging behaviors. Unfortunately, due to its absence as a criterion for diagnosis in the DSM-IV-TR, little attention has been paid to the endorsement rates of such behaviors. However, a recently developed measure to assist in the diagnosis of infants and toddlers with autism and PDD-NOS – the Baby and Infant Screen for Children with aUtIsm Traits (BISCUIT) – has included a section designated for just this reason. This study used the BISCUIT to assess for significant differences in the endorsement rates of challenging behaviors between infants and toddlers with …

Comparing Social Skills In Children With Autistic Disorder And Pervasive Developmental Disorder Not Otherwise Specified, Mary Elizabeth Shoemaker

LSU Master's Theses

Although in recent years there has been a large amount of research on Autism Spectrum Disorders (ASD) in general, relatively few studies have focused on Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS) as a distinct category. As a deficit in social skills is said to be the primary defining feature of ASD, continued research on assessment and treatment of social skills deficits in ASD is warranted. The present study aims to examine the differences in social skills between children diagnosed with Autistic disorder and PDD-NOS using the Matson Evaluation of Social Skills for Youngsters (MESSY). This study extends a previous …
