Dutch Translation of the Manchester-Oxford Foot Questionnaire: Reassessment of Reliability and Validity.
The Manchester-Oxford Foot questionnaire (MOxFQ) is a 16-item patient reported outcome measure developed and validated for use in clinical trials involving foot surgery. The purpose of the present study was to evaluate the psychometric properties of the Dutch translation of the MOxFQ in patients who had undergone a hallux valgus correction. A total of 79 patients who had undergone hallux valgus correction completed the Medical Outcomes Study short-form 36-item questionnaire (SF-36) and MOxFQ before and after surgery. We evaluated the construct validity of the SF-36 versus the MOxFQ and the test-retest reliability. The test-retest reliability was excellent. The internal consistency of the Dutch MOxFQ was high (Cronbach's α of 0.74 to 0.86). The construct validity can be regarded as good, with moderate to high correlations between the Dutch MOxFQ and Dutch SF-36 subscales. In conclusion, the Dutch version of the MOxFQ demonstrated good reliability and validity compared with the SF-36 for use in patient groups that have undergone hallux valgus correction.
