A Comparison of Video Prompting to Least-to-Most Prompting among Children with Autism and Intellectual Disability

Students with autism spectrum disorder (ASD) and intellectual disability (ID) may experience challenges when learning tasks that are complex and require numerous steps. This difficulty can lead to employment issues for this population of learners. Therefore, researchers have explored methods to teach employment-related tasks to students with ASD and ID. Two such procedures are video prompting (VP) and least-to-most prompting. These procedures are frequently combined as an intervention package to boost student responding. The purpose of this study was to explore which of these interventions was more effective and efficient when used to teach office tasks to individuals with ASD and ID. Three adolescent students participated in this study. Using the adapted alternating treatments design, we found that VP was more effective and efficient for two participants, whereas least-to-most prompting was more effective but less efficient for the remaining participant. Implications for research and practice are discussed.
