Using Self-Instruction via Video Activity Schedules to Decrease Reliance on Adult Prompts for Students With an Intellectual Disability

The purpose of this study was to compare the differential effects of mobile assistive technology (AT) loaded with visual activity schedules (VAS; pictures alone) compared to video activity schedules (VidAS; pictures linked to video models) to promote vocational independence and decreased reliance on adult supports for adolescents and adults with intellectual disability, with and without autism. Seven single-case multitreatment designs were used to assess differential effects between the two interventions when participants completed various vocational tasks. All participants were able to perform some of the task steps independently with both VAS and VidAS but demonstrated a greater increase in independence with self-instruction using VidAS than when only given VAS. Results suggest that incorporating VidAS into mobile AT can increase independence while decreasing reliance on additional adult support, suggesting that this could be a reasonable accommodation in school, work, and community settings.
