One of the difficulties in interpreting the findings of different studies is the lack of comparability in the dependent variables used to measure treatment effects. This study compares the outcomes of two therapeutic techniques, a limited form of psychotherapy-counseling and a training device approach based upon conditioning principles. For the psychotherapy and control groups, success was defined as 13 successive nights of no wetting. A failure in the psychotherapy group was any case which did not reach the cure criterion after 12 sessions of therapy, while for the control group a failure was any case that did not reach the cure criterion within 90 days. Cured children in the study were seen in at least one post-treatment follow-up to determine personality and enuresis changes. The study compared a form of psychotherapy-counseling with a training device approach based upon conditioning principles, as treatments for functional nocturnal enuresis.
