BACKGROUND
The Manchester-Oxford Foot Questionnaire (MOXFQ) is a 16-item patient-reported outcome measure (PROM) validated for use in patients with foot and ankle pathologies. It contains three sub-scores for pain, walking/standing and social interaction dimensions. The aim of this study was to develop a French language version of the MOXFQ and to assess its psychometric properties in patients affected by foot and ankle pathologies.
METHODS
According to guidelines, forward and backward independent translations were performed. The final French version was pre-tested in 45 patients. The French MOXFQ and the Short-form 36 Health Survey (SF-36) were filled in by 149 patients. A retest was performed in 39 patients. Internal consistency and test-retest reliability were assessed using Cronbach's alpha and intraclass correlation coefficient (ICC), respectively. Construct validity was assessed by factor analysis, and through correlations of MOXFQ scales with SF-36 scales.
RESULTS
Internal consistency coefficients were high with Cronbach's alpha ranging from 0.79 and 0.94. Test-retest ICCs were between 0.74 and 0.93. No floor or ceiling effects were observed. The correlations between French MOXFQ and French SF-36 subscales were moderate ranging from -0.33 to -0.71.
CONCLUSIONS
The French translation of the MOXFQ revealed good psychometric properties. Our French version proved to be a reliable instrument which can be used for evaluation of patients with foot and ankle disorders.
