The "bathroom game": a systematic program for the elimination of encopretic behavior.

The present investigation utilized a unique, variable ratio schedule of reinforcement (the "bathroom game") to treat a 10-year-old encopretic male. Dependent measures included confirmed incidents of (a) soiling and (b) appropriate bowel movements monitored across an ABAB design (Baseline 1, "Bathroom Game 1", Baseline 2, "Bathroom Game 2") with one-year follow-up. During "bathroom game" conditions, contingent monetary rewards were provided for non-instances of soiling and appropriate bowel movements. Such rewards were progressively and systematically leaned-out over the course of treatment on a pre-determined variable ratio schedule. Results indicated a clear demonstration of functional control and clinically significant treatment effects during both experimental periods. These findings are discussed with regard to the positive features of the "bathroom game" procedure and recommendations are made for future investigations in the area.
