Autism spectrum disorder is diagnosed more in males than females, this difference is even more prevalent if the female is of at least average intelligence. The problem addressed by this qualitative exploratory case study was the under-identification of females with autism due to their masking behavior. This problem directly impacts females who…

A neurological disorder, along with several behavioral issues, may be to blame for a child's subpar performance in the academic journey (such as anxiety, depression, learning disorders, and irritability). These symptoms can be used to diagnose children with ASD, and supervised machine learning models can help differentiate between ASD traits and…

Autism Spectrum Disorder (ASD) is a developmental disorder that impacts areas of social communication and social interaction. The prevalence of ASD has increased in the last ten years. Symptoms and behaviors include restrictive and repetitive movements, highly restricted and fixated interests, insistence on sameness, and hypo or hyper-reactivity.…

Stereotypy or automatically occurring behaviors, as commonly seen in children with autism spectrum disorder, can be divided into three main categories: self-injury, stereotypy, and aggressive behaviors. Researchers have suggested different intervention approaches to treat stereotypy, such as redirecting or replacing undesired action. This Delphi…

The objective of this study is to examine a diverse group of educators and their background knowledge on the overlap of autism spectrum disorder (ASD) and traumatic stress as well as their access to developmentally appropriate trainings and interventions for modified traumainformed care. The current research asks (1) do general education teachers…

Autism spectrum disorder (ASD) is characterized in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; APA, 2013) by deficits in social communication and the presence of restricted and repetitive behaviors and interests (RRBIs). Despite the mandatory requirement of both categories of impairment for a diagnosis of ASD, research…

The present study employed an alternating treatment design to examine the use of a socially assistive robot on the educational outcomes of children with severe symptoms of autism spectrum disorder. Participants included three children, ages 5-7 years old, recruited from a public elementary school in the Northeastern United States. The study…

Anxiety disorders are one of the most commonly re-occurring co-occurring diagnoses of children with autism, affecting approximately as many as 84% of children with ASD (Chalfant, et al., 2006) as opposed to 13% of children without autism (van Steensel et al., 2011). A growing body of research indicates that Cognitive Behavioral Therapy (CBT) is an…

This study had two research questions: how do special educators describe their experiences implementing mindfulness and their perceptions of its usefulness for students with autism spectrum disorder. Multiple data sources were used, including interviews, document analysis, and analytical memoing. A qualitative multiple-case descriptive case study…

Grounded in the biopsychosocial models of expressive language in autism spectrum disorder (ASD) and fragile X syndrome (FXS), this dissertation included two novel studies that examined the role of biological (i.e., physiology), psychological (i.e., autistic traits, anxiety symptoms, and child affect) and social (i.e., communication partner…

There is an increasing awareness among researchers and educators that a significant number of males are diagnosed with autism spectrum disorder (ASD) in comparison to females. Recent research has found noted differences related to ASD characteristics associated with females. The differences are particularly noted in females with average to above…

With the increasing prevalence of autism diagnoses globally, the overall aim of this dissertation is to improve our understanding of the linguistic aptitude of autistic individuals. Given that the autism diagnosis is a spectrum, we rely on the Autism Quotient (AQ) test, which measures the quantity of autistic-like traits an individual possesses,…

Special education is a critical access point for the identification of students with autism spectrum disorder (ASD) and subsequent provision of intervention services. However, it remains unclear which children will qualify for services in the educational setting, as ASD represents a heterogeneous group. The current study used structural equation…

As the number of children and adolescents diagnosed with autism spectrum disorders (ASD) increases, the need for mental health services for this population will increase. As a result, counselors in clinical practice and school must be prepared to provide those mental health services. ASD can be inherently difficult to work with due to core…

Autism Spectrum Disorder (ASD) is diagnosed using the same criteria for males and females (e.g., DSM-5, ICD-10). Our understanding of ASD, including its etiology, symptom presentation, and prevalence has evolved significantly over time motivating several changes to the diagnostic criteria and the tools with which symptoms are measured. One aspect…
