Abstract:
BACKGROUND:In the pediatric population, pathologic bleeding is often challenging to identify. The pediatric bleeding questionnaire (PBQ) was developed as a screening tool for von Willebrand disease (VWD) but was designed to be self-completed by children above 12 years of age. The study objective was to determine whether a modified Self-PBQ could be completed by 8- to 12-year-old children with adult assistance. PROCEDURE:The initial phase involved seven children who underwent cognitive debriefing to identify problems in the questionnaire, resulting in modifications to wording and response options. In phase 2, children completed the modified Self-PBQ independently or with assistance from their parent at five Canadian treatment centers. Parents filled out the Self-PBQ separately to serve as a comparison. Bleeding scores derived from the child self-report were compared to those of the parent proxy. RESULTS:Twenty-nine out of 31 patient/parent pairs successfully completed the Self-PBQ. Child and parent scores demonstrated a high level of agreement with an intraclass correlation (ICC) of 0.825. In the age subgroup analysis, the ICC was 0.834 and 0.824 for the 8- to 9-year-old and 10- to 12-year-old groups, respectively. The ICC was also determined in children with type 1 VWD (ICC = 0.829) versus those with more severe bleeding disorders (ICC = 0.802). Thus, age and disease severity had no significant effect on degree of agreement. CONCLUSIONS:Our study shows that agreement was maintained even in younger children aged 8-9 years and in children with varying bleeding phenotypes. This supports the administration of the modified Self-PBQ to 8- to 12-year-old children.
