Nocturnal enuresis is a common condition that can impact an individual’s life in a variety of ways and may continue to do so without effective treatment. Although enuresis is less common in older children, it is often more severe. There is very little research on the efficacy of treatment for nocturnal enuresis in this age group. The aims for the current study were to: determine the efficacy of a urine alarm-based behavioural intervention programme (The Bedwetting Programme) for older children and to explore whether a motivational youth psychoeducation session could impact treatment outcomes. Nine youths aged 11 to 15 years participated in the current study with their primary caregiver(s). Participants completed baseline, treatment, over-learning and follow-up phases. This also included a parent education session, a motivational youth psychoeducation session and the urine alarm. Additional components were used to assist with progress where needed which included retention control training, shaping and night waking schedules. Participants were randomly assigned to one of two treatment order groups: Group One who had the motivational youth psychoeducation session first and Group Two who had the urine alarm first. Treatment performance was measured by the cessation of bedwetting defined as 14 consecutive dry nights, number of wet nights and treatment duration. Participants also completed the Child Behaviour Checklist, the Parenting Scale – Adolescent and a Self-Efficacy Scale to describe the sample through pre- to post-intervention. The behavioural intervention programme was effective for these older children with all of the eight participants who took part, reaching the dryness criterion. The motivational youth psychoeducation session may have had some impact on treatment performance. These findings suggest that this multi-component behavioural intervention programme is an effective form of treatment for older children. The motivational youth psychoeducation session warrants more work to investigate its effect on young people’s motivation and performance of treatment.
