Cross-cultural adaptation of the Minnesota Living with Heart Failure Questionnaire for German-speaking patients.
We performed a cross-cultural adaptation of the "Minnesota Living with Heart Failure Questionnaire" (LHFQ) for use in German-speaking chronic heart failure patients. The instrument was translated and back translated, pre-tested and reviewed by a committee. The German version was tested in 114 patients with chronic heart failure. Reliability was assessed by a test-retest procedure and Cronbach's coefficient alpha of internal consistency (0.94). To assess concurrent validity, we compared the LHFQ sum scores with the New York Heart Association classification rating (r = 0.53; p < 0.0001), the 6-minute walk (r = -0.39; p < 0.0001), the left ventricular ejection fraction (r = -0.24; p = 0.011) and big-endothelin (r = 0.27; p = 0.004). Construct validity on the LHFQ scores in comparison with the Medical Outcomes Study SF-36 Health Survey (MOS SF-36) was significant (-0.41 to -0.74; all p < 0.0001). The reliability and validity of the German version of the LHFQ was proved; the questionnaire can be recommended for use in future clinical trials.
