The Dutch version of the Oxford Ankle and Foot Questionnaire for Children: Useful for evaluation of pediatric foot problems in groups
Background: The purpose of this study is to develop a Dutch version of the Oxford Ankle and Foot Questionnaire for Children (OxAFQ-c) to allow evaluation of pediatric foot care. Methods: The OxAFQ-c was translated into Dutch, according to the ISPOR-guidelines. Children with different foot and ankle complaints completed the OxAFQ-c at baseline, after two weeks, and after 4-6 months. Measurement properties were assessed in terms of reliability, responsiveness, and construct validity. Results: Test-retest reliability showed moderate intraclass correlation coefficients. Bland-Altman plots showed wide limits of agreement. After 4-6 months, the group that experienced improvement also showed improved questionnaire outcomes, indicating responsiveness. Moderate correlation between the OxAFQ-c and the Kidscreen and foot-specific VAS-scores were observed, indicating moderate construct validity. Conclusions: The Dutch OxAFQ-c showed moderate to good measurement properties. However, because we observed limited sensitivity to changes and wide limits of agreement in individual patients, we think the questionnaire should only be used in groups.
