The Validation Process for Confirmation of the French Version of the Pediatric Quality of Life Inventory :PedsQLTM.

The Duchenne Muscular Dystrophy, the commonest form of dystrophy, is an X-linked, recessive neuromuscular disease, in which there is an absence of the protein dystrophin. This chronic and progressive disease leads to an inevitable loss of autonomy (muscle weakness, respiratory and cardiac failure). With better multidisciplinary care, life expectancy has increased but also morbidity. From now one, the evaluation of the quality of life of children with DMD is necessary in therapeutic trials. Given the specificities of the disease, it seems appropriate to have a specific scale. In the literature there isn't quality of life scale specific to Duchenne Muscular Dystrophy in French version. The only specific scale that exists is the specific module PedsQLTM DMD that was validated in English version in 2012. This scale is relevant for assessing the quality of life in clinical trials and in daily clinical practice given its psychometric properties (good internal consistency close to 0.8).The main hypothesis that we formulate is to validate the French translation of the pediatric module of Duchenne Muscular Dystrophy of the PedsQL ™ 3.0 scale.
