The purpose of this study was to evaluate the use of a Personal Digital Assistant with multiple prompt levels to increase completion of novel task boxes and transitioning within and between tasks. The study used a multiple probe design across three sets of task boxes replicated with three students with a diagnosis of autism spectrum disorder. Results indicated that: task completion was higher for two of the students compared to baseline conditions using a picture-based task strip; all students were able to complete a greater number of between task transitions using the PDA; students performed within task transitions equally as well using the PDA and the task strip; and one student began to self-fade use of more intrusive prompt levels.
