French translation of the Multidimensional Pain Inventory: L'inventaire multidimensionnel de la douleur.

Background: The Multidimensional Pain Inventory (MPI) is a widely used tool in the evaluation of pain conditions. This questionnaire has been translated and validated in multiple languages. However, there is no validated French-language version available for clinicians and researchers interested in evaluating people living with pain.

Objectives: The main objective of the present project was to make available a validated French-language evaluation tool for the cognitive, behavioural and emotional aspects of pain.

Methods: Following a reverse translation of the MPI, a French-language version of the questionnaire, the Inventaire multidimensionnel de la douleur, that was presented to 227 participants living with chronic pain, was obtained. These participants were all involved in a rehabilitation program in four different settings. A series of exploratory and confirmatory factor analyses was executed.

Results And Conclusions: Although three items were removed from the original version of the MPI, the three sections of the Inventaire multidimensionnel de la douleur had good psychometric properties. The results concerning the questionnaire's structure were very similar to those obtained with the original tool and during its translation into other languages. People wishing to evaluate pain in French-speaking populations now have access to a French-language version of the MPI.
