The present investigation adapted a behaviorally-based toilet-training protocol for use with two male children with developmental disabilities. Positive practice and verbal reprimands were eliminated, and reinforcement, scheduled sits, and a urine alarm were utilized. Data were collected on the number of intoilet urinations, urinary accidents, and self-initiations. Results show that both participants exhibited significant improvement in their toileting skills and met the final success criteria rapidly. These results were maintained through follow-up. Implications for the elimination of punishment procedures in future toilet training protocols are discussed.
