This study evaluated the effects of an intervention package designed to teach independent toileting skills to two boys with autism spectrum disorder (ASD). A nonconcurrent multiple-baseline-across-participants design was employed to investigate the effects of video modeling that used animation to depict in-toilet voiding combined with prompting and reinforcement procedures. Results indicated that the intervention package was effective in teaching a sequence of behaviors necessary for successful and independent toileting (e.g., walking to the toilet, undressing, sitting on the toilet, dressing, and flushing) as well as in-toilet urination for both boys. Skills generalized to the school and were maintained over 3 to 4 months. The intervention may have also been responsible for teaching in-toilet defecation for one participant. Results are interpreted in relation to the differential contributions of video modeling and behavioral instructional strategies.
