Evaluating the effects of a video prompt in a system of least prompts procedure

The purpose of this study was to evaluate the effects of a system of least prompts procedure with a video prompt serving as the model in teaching office tasks to three high school students with moderate intellectual disability. A multiple probe across behaviors design replicated across participants was used to evaluate the intervention. The dependent variable was percentage of steps completed independently on collating and stapling papers, organizing a binder, and preparing a letter. Generalization was assessed across materials for each participant in a pre-/post-test format. Results indicated the three participants learned all three skills after the introduction of intervention and generalized the majority of steps to novel materials.
