BackgroundIndividuals with intellectual disabilities need continued supports in completing daily living tasks to increase the likelihood of achieving independence. Fortunately, research has shown that assistive technology, and particularly video prompting helps support independent living for individuals with intellectual disabilities.AimsThis study investigated the efficacy of a highly customizable task analysis smartphone application in assisting three young adults with intellectual disabilities learn how to cook three different multistep recipes.Materials & MethodsThree young adults with intellectual disabilities enrolled in a four‐year postsecondary education program (PSE) participated in a multiple probe design across participants to examine the effect of a Task Analysis app on the participants' completion of three cooking tasks.ResultsIn this present study, the use of video prompting to teach a daily living skill resulted in large and meaningful effect size gains of 99%–100% for all three participants, as measured by Tau‐U.DiscussionVideo prompting is an effective instructional strategy which allows the user to self‐prompt and manage their ability to successfully complete daily living skills. In this current study, video prompting made a substantial difference in the safety of participants.ConclusionThe use of video prompting can decrease the reliance on others (e.g., teachers and caregivers), improve self‐confidence of the user, and improve the user's level of autonomy.
