To teach operant behaviors to individuals with severe disabilities, stimulus preference assessment (SPA) methods have been developed to accurately identify stimuli that may function as reinforcers. Previous researchers have used multiple-stimulus preference assessments without replacement (MSWO) effectively over a short time period to teach target behaviors to individuals with disabilities. The present study investigated the long-term effects of incorporating brief MSWO preference assessments into the instructional routine for students with severe disabilities on individualized education plan reading goal/objective progress. This was done by investigating the effectiveness of incorporating brief MSWO preference assessments by comparing reading goal progress when a random reinforcer is available, teacher- selected reinforcer is available, or a student-selected reinforcer (via a brief MSWO preference assessment) is available over several weeks for students with severe disabilities in a secondary public school classroom setting.
