The Oxford Ankle Foot Questionnaire for Children (OxAFQ-C) is validated for assessing the impact of foot and ankle conditions in pediatric patients. The purpose of this cross-sectional study is to assess child-parent concordance and identify patient factors that predict improved agreement.
Patients aged 8 to 16 years with foot and ankle conditions and their parents completed the OxAFQ-C during routine clinic visits over a 9-month period. Demographic and medical information was collected by chart reviews. Responses in each domain were compared using a Wilcoxon signed-rank test, and the comparisons of responses by sex were analyzed with Wilcoxon rank-sum tests. Concordance was assessed with intraclass correlation coefficients.
There were 87 child-parent dyads with 50 female patients (57.5%) and 37 male patients (42.5%). Most parent responders were mothers (84%). The mean patient age was 12.4 (±2.2) years. The most common diagnosis was pes planus (17%). Child scores were significantly higher than their parents' in the school and play (P = 0.008) and emotional (P = 0.001) domains. When stratified by age, children younger than 13 years had significantly higher scores than their parents across all domains (P = 0.015 physical, 0.002 school and play, 0.001 emotional), although the concordance for the school and play and emotional domains was only moderate (0.73 and 0.58, respectively). Female patients and their parents reported significantly lower scores compared with their male counterparts only in the emotional domain (84.37 vs 93.75, P = 0.025).
Concordance is good between child and parent scores of the OxAFQ-C for assessing the impact of foot and ankle conditions. When stratified by age, patients younger than 13 years of age had higher scores than their parents' in all domains with the lowest concordance for the school and play and emotional domains. Female patients and their parents reported significantly lower scores than their male counterparts in the emotional domain.
