COMPARATIVE-STUDY OF THE VALIDITY OF 4 FRENCH MCGILL PAIN QUESTIONNAIRE (MPQ) VERSIONS

Four different French versions of the McGill Pain Questionnaire (MPQ) have been published: 3 are MPQ translations in Canadian French and 1 (QDSA) is an MPQ reconstruction in (France) French. The aim of our work was to study the validity of these available questionnaires for use in France. The validity was evaluated by 44 French physicians. Various validity criteria were studied: item, dimension, subclass and pain descriptor intensity. A new French MPQ was also developed. Significant validity differences emerged between the different MPQ versions. This study confirms the satisfactory validity of the QDSA. The validity of the newly developed French MPQ was equal but not better than the QDSA. A 15-item short MPQ-QDSA version was also developed. For studies with patients from France, it is recommended that the QDSA or the short MPQ-QDSA versions be used.
