The Baby And Infant Screen For Children With Autism Traits: Age-Based Scoring Procedures, Max Horovitz
The Baby And Infant Screen For Children With Autism Traits: Age-Based Scoring Procedures, Max Horovitz
LSU Doctoral Dissertations
As increasing interest and emphasis has been placed on early intervention for children with Autism Spectrum Disorders (ASD), the need for reliable and valid early assessment techniques has grown significantly. The Baby and Infant Screen for Children with aUtIsm Traits (BISCUIT) is a three-part battery designed to comprehensively assess for ASD in infants and toddlers aged 17 to 37 months. While studies of the measure’s psychometric properties have been promising, the measure’s scoring procedures do not take the child’s age into account. Given the significant amount of development that occurs in the first three years of life, the current paper …
Challenging Behaviors In Autism Spectrum Disorders : Differences Across Childhood And The Relationship With Autism Symptomatology, Alison Marie Kozlowski
Challenging Behaviors In Autism Spectrum Disorders : Differences Across Childhood And The Relationship With Autism Symptomatology, Alison Marie Kozlowski
LSU Doctoral Dissertations
Challenging behaviors (CBs) are remarkably prevalent in individuals with autism spectrum disorders (ASDs) and can have a number of severe consequences. While it is believed that CBs reach their peak in childhood followed by a general abatement throughout adolescence and adulthood, the exact trend of CBs during childhood is unknown. Furthermore, the impact of changes in autism symptomatology on CBs during childhood has seldom been explored despite a positive correlation between autism symptomatology and CBs having been established. Therefore, the purpose of these studies was to determine where significant differences in both autism symptomatology and CBs occur throughout childhood, and …
Exploratory And Confirmatory Factor Analyses Of The Symptom Structure For Autism Spectrum Disorders Using The Baby And The Infant Screen For Children With Autism Traits, Megan Sipes
LSU Doctoral Dissertations
Since autism spectrum disorders (ASD) were first identified, the diagnostic criteria and conceptualization of symptom structure have undergone many revisions. Currently, under the Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition-Text Revision (DSM-IV-TR; American Psychiatric Association (APA), 2000), ASD is defined by three symptom categories: impairments in socialization, deficits in communication, and repetitive/restricted behaviors. With the publication of the DSM-5 (APA, 2011), however, ASD will be defined by a two symptom cluster structure in which the main impairments are in the areas of social communication and restricted/repetitive behaviors. With these changes, many assessment measures will need to be re-examined to …
