A reproducible pediatric daytime urinary incontinence questionnaire

Purpose: We developed and tested the reliability of a new, structured, pare nt administered questionnaire to determine the prevalence of and risk facto rs for daytime urinary incontinence in children. Materials and Methods: A new questionnaire was developed and evaluated in a pilot study for ease of understanding and acceptability. It was then teste d for reproducibility of responses in a randomly selected sample of new pri mary school entrants in Western Sydney 4 weeks after baseline data were col lected. The questionnaire obtained data on demographics, prevalence of dayt ime incontinence, family history of incontinence, voiding symptoms and soci oeconomic status. Categorical data agreement was assessed using the kappa s tatistic and continuous data agreement was analyzed using the Bland-Altman method. Results: A total of 166 subjects 3.5 to 7 years old (mean and median ages 5 .6 and 5.7, respectively) completed the repeat questionnaire with a 78.5% r esponse rate. Mean agreement of the responses to the first and second quest ionnaires was 91% (range 83% to 100%, mean kappa = 0.70, range 0.34 to 1.00 ). For continuous data the 95% confidence limits were narrow (0.3 for birth weight data). Conclusions: We have developed a new daytime urinary incontinence questionn aire using parent reported data and demonstrated that it is reproducible. W e consider it to be a useful instrument for ascertaining information on uri nary incontinence and other voiding symptoms.
