An understanding of the psychological impact of nocturnal enuresis has been consistently hampered by inter-changeability of terminology, varied inclusion criteria, diverse methodologies and equivocal findings. This paper reviews the impact on children and young people by examining both qualitative and quantitative findings. Aspects of functioning that are explored include social adjustment, emotional state, personality, self- concept and behaviour. Generally the findings suggest children do experience bedwetting as distressing but those with mono-symptomatic nocturnal enuresis are no different from the normal population or from matched controls across all aspects of functioning. Those children most vulnerable to psychological distress as a consequence of bedwetting are identified. Interestingly there is consistent evidence for improvement in emotional functioning and self-esteem following treatment although this may not be necessarily due to the treatment itself. Methodological issues are addressed in terms of future research directions.
