ABSTRACT
Video-based instruction has been effective in teaching a range of skills, including functional living skills, to individuals with autism spectrum disorder. Few studies have compared the efficacy and efficiency across video modality-specifically, comparing video modeling to video prompting. Consequently, practitioners have little empirical guidance when selecting between procedural variations of video-based instruction. Using an adaptive alternating-treatments design with a baseline, we evaluated the comparative effectiveness of point-of-view video modeling and video prompting on the percentage of meal preparation tasks completed correctly and on-task behavior with 4 adolescents with autism spectrum disorder. We found video modeling to be effective and efficient in the acquisition of meal preparation skills across 3 of the 4 participants. Across participants, video prompting resulted in more errors than video modeling did. Skills generalized to an untrained location and were maintained at a 3-week follow-up. Stakeholders reported procedures, goals, and outcomes as socially valid.
