Abstract
Questionnaires must be translated and adapted to suit the cultural characteristics of different countries with different languages; they then need to be validated using a standard process. This was done for the Italian version of the Oxford Knee Questionnaire (OKQ), and its reliability and validity were assessed in a cross-sectional study of 50 consecutive patients referred for gonarthrosis and whose knees were replaced. A "subsample" of 20 patients was assessed prospectively to confirm the reliability of the Italian version, and these results were then compared with other clinical studies. The Italian OKQ scale correlated well with other clinical studies and also showed good results with regard to reproducibility, consistency, and validity when compared to the other published versions of the OKQ.
Résumé
Les questionnaires doivent être traduits et doivent être adaptés pour convenir aux caractéristiques culturelles de pays différents avec des langues différentes, et ils ont besoin d'être validés en utilisant un processus standard . Cela a été fait pour la version italienne de l'Oxford Genou Questionnaire (OKQ). Sa précision et sa validité ont été étudiées dans une étude croisée d'un groupe de 50 malades consécutifs opérés par prothèse pour gonarthrose. Un sous-échantillon de 20 malades a été étudié pour confirmer la fiabilité de la Version italienne. Ces résultats ont été comparés avec les autres études cliniques . L'échelle OKQ italienne a bien correspondu avec les autres études cliniques. Il a aussi montré de bons résultats quant à la reproductibilité, la valeur et la validité en comparaison à d'autres versions publiées de l'OKQ.
