The aim is adapting and validating the MOXFQ for European-Spanish population, while assessing its psychometric properties. Method: Translation and cross-cultural adaption (MOXFQ-EUROSpa) was performed from MOXFQ-English original test. Its psychometric properties (reliability, internal consistency, floor and ceiling effects, construct validity and responsiveness) were calculated in 102 patients operated of orthopaedic F&A surgery in a Spanish hospital between 2021 and 2022. It was applied MOXFQ-EUROSpa, VAS-pain and EURO-QoL questionnaires. Data analyzed with SPSS.13.0; p-value < 0.05 Results: MOXFQ-EUROSpa showed excellent reliability (ICC=0.94 MOXFQ-index) and strong internal consistency (Cronbach's alpha=0.95 MOXFQ-index). Strong correlation with EuroQoL and VAS-pain confirmed validity. Good to excellent responsiveness for all domains, except MOXFQ-social(moderate). Postoperative MOXFQ-social had a floor effect. Conclusion: MOXFQ-EUROSpa demonstrated good psychometric properties therefore it should be considered to evaluate elective foot and ankle procedures results.
