Individuals with intellectual disabilities (ID) often experience a combination of both intellectual and adaptive functioning deficits that impact conceptual, social, and practical domains. These deficits can negatively impact an individual's ability to achieve independence and sustained employment. Fortunately, research has shown assistive technology can help support employment skills for individuals with ID. This multiple baseline design study investigated the use of a Task Analysis smartphone application, which utilized video and audio prompting, with four young adults with ID on the completion of work-related office tasks. Findings indicate that all four young adults with ID showed large effect size gains for completing several common office-related tasks including shredding, copying, and scanning. Implications and future research are discussed.
