The current evaluation assessed the effectiveness of a rapid toilet training procedure for three young males with autism. The evaluation extended the research on rapid toilet training procedures by assessing parents' preference to include two common toilet training components, a urine alarm and positive practice. In addition, we assessed child challenging behaviors during intervention. All parent participants' elected not to use the urine alarm, and one parent elected to discontinue the implementation of positive practice techniques. All child participants engaged in challenging behavior with the initiation of toilet training. The toileting intervention was successful as all three participants increased successful self-initiations for the toilet and decreased accidents across home and clinic settings. All parents provided favorable social validity ratings of the treatment. Findings suggest that clinicians should partner with parents to develop individualized toileting interventions that are appropriate and effective.
