Due to the unique social cognitive profiles of individuals with autism spectrum disorder (ASD) with and without intellectual disability (ID) sharing coherent and complex personal narratives can be challenging. To address these challenges research has focused on teaching macrostructure components using visual supports and repeated opportunities to practice. Despite success by young children with ASD and ID, the application of this instruction for adults with ASD with and without ID is still largely unknown. An ABAB single case withdrawal design was used to determine the effects of a personal narrative intervention to teach macrostructure within participant-generated personal narratives. Results indicate all participants demonstrated more coherent and complex personal narratives with the intervention. The results and implications for practice are discussed.
