• Objective: To develop a reliable and valid scoring tool, the Pediatric Bowel Management Scoring Tool (PBMST), to better guide management of constipation in pediatric patients. Study design: The project comprised 2 stages, development of the questionnaire and construction of the bowel management score. Two questionnaires were created, one for children aged 8-18 years to self-report and one parent proxy-report for children aged 4-8 years. Questions regarding physical symptoms (n = 6), emotional aspects (n = 2), social activities/school (n = 1), and treatment (n = 1) were included. Patients (or parents of patients) with symptoms of constipation completed the questionnaire. The reproducibility of each question was computed using the Cohen weighted kappa coefficient (κ). A bowel management score was developed using logistic regression analysis, assessing the associations between the questions and impact on self-reported quality of life (QoL). Questions with adequate reproducibility and significantly associated with QoL were incorporated into the score. Results: The questionnaire was completed by 385 patients. Six questions met the inclusion criteria and were incorporated into the score: stool shape (range, 0-3 points), anorectal pain (0-4 points), abdominal pain (0-3 points), frequency of fecal incontinence (0-3 points), assistance of caregivers (0-3 points), and interference with social activities (0-6 points). Differences in bowel management scores among patients reporting no, little, some, or major impact on QoL were statistically significant (P < .001). Conclusions: The newly developed and validated PBMST is a reliable tool for evaluating bowel management strategies in children with constipation.
