To evaluate the efficacy of an operant approach that includes the bell and pad for the treatment of enuresis (Tangible Rewards with Fading), it was compared with an established operant method that includes the bell and pad (the Dry Bed method) and to a conventional Bell and Pad method. Although there were no overall statistically significant differences among the three methods, individual pairwise comparisons were of interest; the Dry Bed method had no advantage, but the Tangible Rewards with Fading method tended to have more patients reach a 14-day dryness criterion (p less than 0.10) and tended to have fewer patients relapse after treatment (p less than 0.08) than the Bell and Pad method.
