In Vivo Use of Picture Prompt Training to Increase Independent Work at a Restaurant

Procedures used to train an adult with severe disabilities to perform a variety of food service tasks in a restaurant are described. Dependent measures included (a) the rate of prompts delivered per 5-min interval and (b) the percentage of steps of the task analyses performed correctly. A multielement feature was embedded within a multiple baseline design, which allowed experimenters to determine when fading of instructional stimuli should occur. Maintenance and long-term follow-up data are presented. Following 20 months of employment, the owners continue to express their satisfaction with the participant's work performance.
