Presenters will discuss relevant current research on cognitive–behavioral therapy (CBT) and autism spectrum disorders (ASDs) with specific focus on understanding underlying deficits that contribute to challenging behaviors and deficient social skills. Presenters will use didactic presentation to provide a foundation for using a case conceptualization approach for children with ASD that includes linking assessment to treatment planning. Participants will gain an understanding of CBT interventions from a modular-based and manual-based CBT approach. Videotaped cases will be used to demonstrate some of the interventions discussed. To tie the elements of this presentation together, participants will engage in small group case discussions to develop case conceptualization, treatment planning, intervention selection, progress monitoring, and generalization of skills.
