RESUMO
Using a treatment package featuring the urine alarm, this study evaluated a treatment process for nocturnal enuresis. Children who received the training were classified into treatment successes (N = 38) and nonsuccesses (N = 19) according to a criterion (3-week continence). Their daily results were analyzed with four categories: dry with sleep (DS), dry with spontaneous awakening (DA), wet with spontaneous or alarm-forced awakening (WA), and wet with sleep (WS). In a trend analysis, an increase of DA over the treatment process was prominent for successes compared to nonsuccesses. Entering WA to a discriminant analysis, 86% of children were correctly classified into the two groups. The findings that awakening categories well distinguished successes from nonsuccesses provide support for an active avoidance model explaining the efficacy of urine-alarm treatment for nocturnal enuresis.
