The Relationship Between Type Of Parental First Concerns And Severity Of Developmental Delays In Toddlers With Autism Or Developmental Delay, Joshua J. Montrenes
The Relationship Between Type Of Parental First Concerns And Severity Of Developmental Delays In Toddlers With Autism Or Developmental Delay, Joshua J. Montrenes
LSU Master's Theses
Autism spectrum disorder (ASD) is characterized by impairments in social communication and the presence of restricted, repetitive behaviors. The impairments which are commonly associated with ASD manifest during early development as delayed speech or impaired social skills, for example. These early indicators are often noticed by parents who convey concern to medical professionals. Research has found associations between these early parental concerns and a later diagnosis of autism, noting their predictive validity. Research has yet to address the relationship between types of parental concerns and developmental functioning. This study examined whether certain parent reported concerns are more predictive of impaired …
Developmental Functioning Of Infants And Toddlers With Autism And Cerebral Palsy, Xinrui Jiang
Developmental Functioning Of Infants And Toddlers With Autism And Cerebral Palsy, Xinrui Jiang
LSU Master's Theses
Children with Autism Spectrum Disorder (ASD) often have one or more comorbid medical conditions including cerebral palsy (CP). Due to the overlaps between ASD and CP symptomatology (e.g., impairments in speech, repetitive movements, atypical sensory issues), co-occurring CP often leads to delayed diagnoses of ASD interfering with early interventions and subsequently affecting functional outcome. Utilizing the Baby and Infant Screen for Children with aUtIsm Traits-Part 1 (BISCUIT-Part 1) and the Battelle Developmental Inventory, Second Edition (BDI-2), this study assessed and compared ASD symptomatology and developmental functioning in three groups of infants and toddlers, namely, those with ASD only, those with …
Change In Developmental Quotient In Toddlers Assessed For Autism Spectrum Disorder, Lindsey Willis Williams
Change In Developmental Quotient In Toddlers Assessed For Autism Spectrum Disorder, Lindsey Willis Williams
LSU Master's Theses
ASD is marked by significant delays in social and language development, while development in other areas, such as cognitive functioning, can be highly variable from person to person. Though preschool-aged children with ASD often exhibit a profile of developmental delays similar to children with other developmental disorders at a discrete moment in time, few studies have investigated possible differences in rate of skill acquisition in developmental domains in children with different disorders. Sensitive periods of development are marked by less stability in performance of developmental skills. Results of prior studies suggest that if appropriate early interventions are applied during sensitive …
Challenging Behaviors In Children With Comorbid Autism Spectrum Disorder And Attention-Deficit/Hyperactivity Disorder, Katherine Margaret Macmillan
Challenging Behaviors In Children With Comorbid Autism Spectrum Disorder And Attention-Deficit/Hyperactivity Disorder, Katherine Margaret Macmillan
LSU Master's Theses
Challenging behaviors, such as aggression, destruction, self-injurious behaviors, or stereotypic movements, affect the majority of individuals with Autism Spectrum Disorder. One factor that is known to influence the frequency at which challenging behaviors occur is the presence of a comorbid disorder. Attention-deficit/hyperactivity disorder (ADHD) is thought to be one such disorder. This study aimed to compare the prevalence rates of challenging behaviors, according to the Autism Spectrum Disorder-Behavior Problems, Child Version (ASD-BPC), in children ages 6-16 with parent reported symptoms of ASD, ADHD, comorbid ASD/ADHD, and no diagnosis. Differences existing overall were examined as well as differences on the ASD-BPC’s …
Premature Birth As A Factor In Autism Spectrum Disorder, Rachel Lichtenstein Goldin
Premature Birth As A Factor In Autism Spectrum Disorder, Rachel Lichtenstein Goldin
LSU Master's Theses
Autism Spectrum Disorder (ASD) is characterized by pervasive delays in socialization, communication, and repetitive behaviors and restricted interests. While there is a growing body of evidence on the etiology of ASD, there are a limited number of studies examining factors which may impact the differentiation of ASD compared to other developmental disabilities. Additionally, few studies have examined factors which may predict level of ASD symptom severity. The primary aim of this study was to investigate whether premature birth occurs more commonly in infants and toddlers (17-37 months) with ASD than those with atypical development. A secondary aim of this study …
The Moderating Effect Of Gender On The Relationship Between Socialization And Internalizing Problems In Early Childhood, Hilary Lynn Adams
The Moderating Effect Of Gender On The Relationship Between Socialization And Internalizing Problems In Early Childhood, Hilary Lynn Adams
LSU Master's Theses
Researchers in the field of Autism Spectrum Disorders (ASD) have confirmed that comorbidities are a common problem among diagnosed individuals. Current estimates suggest that more than two thirds meet criteria for an additional diagnosis of psychopathology. In particular, rates of several internalizing problems (i.e., anxiety, depression) appear to be greater for individuals with ASD than their typically developing counterparts. However, little research has been conducted examining factors apart from autism symptomatology that could influence this prevalence difference. Additionally, it is well established that anxiety and depression are more common in females than males in the general population. However, few studies …
An Examination Of The Relationship Between Communication And Socialization Deficits In Infants And Toddlers With Autism And Pervasive Developmental Disorder-Not Otherwise Specified (Pdd_Nos), Megan Alice Hattier
LSU Master's Theses
Autism Spectrum Disorders (ASDs) are characterized by pervasive impairments in repetitive behaviors or interests, communication, and socialization. As the onset of these features occurs at a very young age, early detection is of the utmost importance. In an attempt to better clarify the behavioral presentation of communication and socialization deficits to aid in early assessment and intervention, impairments in these areas were examined among infants and toddlers (17-37 months) with Autistic Disorder (AD), Pervasive Developmental Disorder – Not Otherwise Specified (PDD-NOS), and non-ASD related developmental delay. The Baby and Infant Screen for Children with aUtIsm Traits-Part1 (BISCUIT-Part1) and the Battelle …
Communication Deficits In Babies With Autism And Pervasive Developmental Disorder - Not Otherwise Specified (Pdd-Nos), Max Horovitz
Communication Deficits In Babies With Autism And Pervasive Developmental Disorder - Not Otherwise Specified (Pdd-Nos), Max Horovitz
LSU Master's Theses
Autism Spectrum Disorders (ASDs) are characterized by pervasive impairments in communication, socialization, and repetitive behaviors or interests. While there is a growing interest in early ASDs, very few studies have looked at the nature of these impairments before age 3. In order to better strengthen early assessment and intervention for ASDs, more knowledge is needed in this area. The current studies aimed to determine if, and in what ways, communication impairments are present in infants and toddlers (17-37 months) diagnosed with autism and Pervasive Developmental Disorder – Not Otherwise Specified (PDD-NOS). In the first study, infants with autism and PDD-NOS …
Gender Differences In Children With Autism Spectrum Disorders And Comorbid Psychopathology, Julie Hess
Gender Differences In Children With Autism Spectrum Disorders And Comorbid Psychopathology, Julie Hess
LSU Master's Theses
Abstract Children and adolescents diagnosed with Autism Spectrum Disorders (ASD) frequently exhibit symptoms that are not associated with the core features of ASD. These symptoms may meet criteria for an additional diagnosis; however, accurate assessment of comorbid psychiatric conditions in ASD has been hindered by a lack of measures designed for this specific purpose. The newly constructed assessment measure, Autism Spectrum Disorders-Comorbid for Children (ASD-CC) has been developed specifically for examining comorbid psychiatric disorders in ASD. Therefore, this study set out to assess differences in the endorsement rates of psychiatric symptoms in children and adolescents diagnosed with ASD compared to …
A Comparison Of Feeding And Mealtime Problems In Intellectually Disabled Adults With And Without Autism, Jill Cherie Fodstad
A Comparison Of Feeding And Mealtime Problems In Intellectually Disabled Adults With And Without Autism, Jill Cherie Fodstad
LSU Master's Theses
Due to the dearth of information categorically describing feeding behaviors in those with autism spectrum disorders, the goal of this research is to examine the nature of feeding difficulties in adults with intellectual disabilities (ID) and Autism Spectrum Disorders (ASD). Feeding and mealtime behavior problems are an area of concern due to their impact on an individual’s daily functioning, as well as the potential for causing severe medical conditions (e.g., poor nutrition, choking, aspiration) that may ultimately lead to death. Due to the importance of this topic for proper diagnosis and treatment planning, a better understanding of these behaviors in …
Comorbid Psychological Disorder In Individuals With Intellectual Disabilities And Autism Spectrum Disorders, Jessica Ann Boisjoli
Comorbid Psychological Disorder In Individuals With Intellectual Disabilities And Autism Spectrum Disorders, Jessica Ann Boisjoli
LSU Master's Theses
Autism spectrum disorders (ASD) are characterized by deficits in three areas of functioning: communication, socialization, and restricted interests/repetitive behavior. With the rise in diagnoses of ASD in recent years, these disorders have received increasing recognition by researchers and clinicians. These efforts have largely been with young children. However, the study of ASD and comorbid disorders in adults with intellectual disability (ID) has been almost nonexistent. While there are measures available to assess comorbid disorders in people with only ID, the differences in adults with ASD and ID and adults with ID alone may also be a good deal different than …
Deficits In Social Skills And Feeding Behaviors Associated With Adults Diagnosed With Autistic Disorder Living In An Institutionalized Setting, Cindy Terlonge Graham
Deficits In Social Skills And Feeding Behaviors Associated With Adults Diagnosed With Autistic Disorder Living In An Institutionalized Setting, Cindy Terlonge Graham
LSU Master's Theses
Autistic disorder, a syndrome beginning in infancy and persisting into adulthood, has captured the attention of researchers and clinicians alike. Although this disorder has been studied since the mid-1940s, there is a lack of literature addressing certain adaptive skills in adults with autism. The aim of this study was to examine the differences in social and feeding skills between individuals with and without autistic disorder. Given the importance of acquiring these skills to facilitate proper adjustment and decrease potential health risks, better understanding of these behaviors in persons with autism is warranted. Participants comprised three separate groups: an autism group, …
The Effects Of Reinforcement Magnitude On Functional Analysis Outcomes, Valerie Marie Volkert
The Effects Of Reinforcement Magnitude On Functional Analysis Outcomes, Valerie Marie Volkert
LSU Master's Theses
The functional analysis methodology developed by Iwata, Dorsey, Slifer, Bauman, and Richman (1982/1994) has been successfully used to identify the variables that maintain the problem behavior of individuals with developmental disabilities. However, in some cases, the results of functional analysis may be inconclusive. Altering parameters of reinforcement, such as the schedule, the quality, or magnitude of the reinforcer, may increase the likelihood of obtaining clear functional analysis results. Few studies have evaluated the effects of reinforcement magnitude on problem behavior even though basic findings indicate that this parameter may alter functional analysis outcomes. In fact, reinforcement magnitude has varied widely …
Reliability And Concordance Of The Childhood Autism Rating Scale And Dsm-Iv In Adults With Severe And Profound Mental Retardation, Noha Farrah Minshawi
Reliability And Concordance Of The Childhood Autism Rating Scale And Dsm-Iv In Adults With Severe And Profound Mental Retardation, Noha Farrah Minshawi
LSU Master's Theses
Researchers and clinicians have long treated autism as though it were a disorder that only affected children. As a result, little literature is available on the diagnosis, assessment, and treatment of adults with autism. One of the first issues to address in this population is diagnosis. While several rating scales and diagnostic systems exist for surveying autistic behavior in children, researchers have not demonstrated the reliability of these scales for adults. The present study focused on two commonly used instruments, the Childhood Autism Rating Scale (CARS) and the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). In the …
