Eighty percent of COPD patients experience dyspnea during activities of daily life (ADL). To the best of our knowledge, the Modified Medical Research Council (MMRC) dyspnea scale is the only validated scale designed to quantify dyspnea during ADL available in the French language. Two other instruments are only available in English versions: the London Chest Activity of Daily Living (LCADL) scale that allows a specific evaluation of dyspnea during ADL and the Dyspnea-12 questionnaire that evaluates the affective (emotional) and sensory components of dyspnea in daily life. The aim of this study was to translate and validate French versions of both LCADL and Dyspnea-12 questionnaires and to determine the reliability of these versions for the evaluation of dyspnea in severe to very severe COPD patients. Both translation and cultural adaptation were based on Beaton's recommendations. Fifty consecutive patients completed the French version of LCADL and Dyspnea-12 and other questionnaires (MMRC, Saint George's Respiratory Questionnaire [SGRQ], Hospital Anxiety and Depression [HAD]), at a 2-week interval. Internal consistency, validity, and reliability of LCADL and Dyspnea-12 were evaluated. The French version of LCADL and Dyspnea-12 demonstrated good internal consistency with Cronbach's α of, respectively, 0.84 and 0.91. LCADL was correlated significantly with item activity of SGRQ (ρ=0.55, <0.001), total score of SGRQ (ρ=0.63, <0.001), item impact of SGRQ (ρ=0.57, <0.001), and HAD-depression (HAD-D) (ρ=0.47, =0.001); and Dyspnea-12 was correlated significantly with MMRC (ρ=0.39, <0.001), HAD-anxiety (ρ=0.64, <0.001), and HAD-D (ρ=0.64, <0.001). The French version of LCADL and Dyspnea-12 demonstrated good test-retest reliability with, respectively, intraclass coefficient =0.84 ( <0.001) and 0.91 ( <0.001). The French versions of LCADL and Dyspnea-12 questionnaires are promising tools to evaluate dyspnea in severe to very severe COPD patients.
