The Oxford Ankle Foot Questionnaire for Children (OxAFQ-C) is a validated patient reported outcome tool for paediatric foot and ankle conditions. It includes three domains with a maximum score of 100: physical, school and play, and emotional. The purpose of this cross-sectional study is to examine the differences between self-reported child and parent responses of different age groups, genders, and child-parent combinations.

During a ten-month period, paediatric patients aged eight to 16 years and their parents completed the OxAFQ-C during routine clinic visits, providing a total 116 child-parent questionnaire dyads. Demographics and diagnostic information was obtained through medical record review. Parent and child responses in each domain were compared for concordance and for effect of demographic variables on the results. Means and standard deviations for parent and child questionnaires for each domain were reported and compared using a two-sample Wilcoxon rank-sum test. A multivariate regression model was used to assess the correlation between demographic characteristics with domain scores. Absolute agreement between patient and parent questionnaires was assessed using intra-class correlation coefficients (ICC) with a two-way random effects model.

Seventy patients (60.3%) were female and 46 (39.7%) were male, the majority of parent respondents were mothers (85.3%), followed by fathers (11.2%). Mean patient age was 12.4 (± 2.2) years. Higher scores were reported by the child in every domain, though only the emotional domain score showed statistical significance (p = 0.024) between the parent scores. Male children scored significantly higher than females in school and play domain, (mean 82.38 vs 71.13, p = 0.037) and in the emotional domain (means 90.89 vs79.10, p = 0.002). Parents of males scored significantly higher than parents of females only in the emotional domain (means 86.95 vs 72.67, p = 0.001). Children younger than 13 years old scored significantly higher than older children in the emotional domain (p = 0.004).

Child and parent responses for the OxAFQ-C are statistically concordant in the physical and school and play domains. Though children consistently scored themselves higher than their parents did in all domains, only differences in responses for the emotional domain were significant. The level of agreement between parent and child increases with in patients over 13 years of age. Both females and parents of females report lower scores than males and their male parents. Though the use of OxAFQ-C is supported and confirms parent perception of their child's foot and ankle condition is accurate, further research is needed to better understand gender and age differences on response concordance.
