This study investigated the effectiveness of a treatment package that included video technology (e.g., video modeling and video prompting) to teach three self-help skills (e.g., cleaning sunglasses, putting on a wrist watch, and zipping a jacket) to 3 elementary school students with mental disabilities in a small group setting. Using a constant time delay (CTD) procedure, observers measured the percentage of steps of the task analyses performed correctly before and after a video model prompt. A multiple probe design across behaviors, replicated across participants, demonstrated experimental control. The results indicate that an instructional package that includes video technology can be an effective method for teaching self-help skills to students with mental disabilities.
