Recent studies have indicated Cognitive Behavioral Therapy (CBT) as a promising treatment for anxiety in children with autism. However, this line of treatment has only been investigated in high-functioning children with autism. The purpose of this study is to investigate the effectiveness of an adapted CBT protocol in treating anxiety for children with autism and IQ's < 70. Several adaptations, such as play-based techniques, incorporation of mantras, and simplified rating systems, were employed with an 11-year old boy with autism and anxiety symptoms. A single-case pre-post design was employed. The primary measures included session-by-session parent ratings of the participant's three highest rated anxiety symptoms, as well as a pre-post clinical anxiety interview conducted with the parent. Results indicate that this treatment was effective at treating the anxious symptoms of the participant based on Simulation Modeling Analysis, visual inspection, and standard mean difference calculations. This study provides preliminary evidence for this intervention protocol in treating the anxiety of children with autism and an intellectual delay.

Autism symptoms are typically assessed in laboratory environments without evaluating contextual variables from the child’s environment. Home environment factors such as access to activities and parental interaction style play a role in children’s development. The purpose of this project is to characterize children with autism in their home environment by (a) developing and evaluating observable measures of autism symptoms and child engagement in the home (b) using existing measures to assess parental interaction style and household activities (c) assess the degree to which these variables are related. Using a sample of 44 children with autism, reliability calculations were conducted for the novel measures, average scores of autism severity, engagement, parent behaviors, were reported, and mixed linear models and intercorrelation matrices were generated to assess associations between these variables. The novel measures were rated with good reliability and convergent validity. There was a clear relationship between parent behaviors, child engagement, and child autism symptoms. On an average day, children were most likely to be engaged in electronics and/or homework. The findings from this study have the potential to improve understanding of home life in children with autism and illuminate important home characteristics that may influence effectiveness of interventions.
