Abstract
Background
The purpose of the study was to evaluate the reliability and validity of the Turkish version of the Oxford Ankle Foot Questionnaire (OxAFQ) to provide cultural adaptation.
Methods
This study involved translation, back translation, and cross-cultural adaptation. Forty-nine patients with congenital talipes equinovarus were evaluated using the Turkish version of OxAFQ. Turkish version of the Childhood Health Assessment Questionnaire (CHAQ) was used as a gold standard to validate the Turkish version of the OxAFQ. The validation was assessed with Spearman correlation analysis by using CHAQ. The reliability of the questionnaire was assessed with Cronbach alpha (internal consistency) and exploratory factor analysis.
Results
High validity was found between OxAFQ and CHAQ (r = -0.422−0.292) (p < 0.01). Reliability analysis showed that OxAFQ had a high level of Cronbach alpha (α = 0.88−0.96) and internal consistency (ICC = 0.90−0.96).
Conclusion
The Turkish version of OxAFQ is a valid, reliable and useful quality of life questionnaire in patients with congenital talipes equinovarus and it is proper for use by health professionals and researchers.
