Self-instruction using videos or other supports on a mobile device is a pivotal skill and can increase independence for individuals with disabilities by decreasing a need for adult supports. This study evaluated the effects of progressive time delay (PTD) to teach four adolescents with autism and intellectual disability how to initiate self-instruction in the presence of a task direction for an untrained task. Participants were screened for imitating video models prior to the study and were taught to navigate to videos on an iPhone(®) in history training. A multiple probe design across settings embedded in a multiple probe design across participants was used to evaluate the effects of PTD on initiation of self-instruction. All participants learned to self-instruct. Two participants generalized self-instruction to two novel settings. Two participants required instruction in two settings before generalizing to the third. Three participants generalized self-instruction in the presence of a task direction from the researcher to a task direction from their classroom teacher in all three settings. One participant generalized to a task direction presented by the classroom teacher in one setting, but not in the other two. All participants maintained self-instruction behaviors assessed 1 week after all participants met criteria in all settings. Self-instruction using videos or other supports on a mobile device is a pivotal skill and can increase independence for individuals with disabilities by decreasing a need for adult supports.
