Objective: To develop and validate a cross-cultural version of the Manniche Low Back Pain Rating ... more Objective: To develop and validate a cross-cultural version of the Manniche Low Back Pain Rating Scale (MRS) for use in German-speaking low back pain patients. Background: Clinical intervention research in back pain would be enormously facilitated if a small number of relevant, patient-centred questionnaires became internationally used. MRS seems to be particularly suitable for crosscultural adaptation due to its coverage of multidimensional back pain-specific health domains. Methods: MRS was translated and back-translated, pretested and reviewed by a committee. The German version was tested in 126 patients with low back pain from all countries of German-speaking Europe. Reliability (subsample n = 20), dimensionality and construct validity was assessed. Single-dimensionality, higher correlations of MRS with the physical scales compared with the mental scales of the MOS SF-36, a moderate to good correlation with the Roland Morris Questionnaire and a low correlation with the Finger Floor Distance were hypothesized. Results: Spearman's Rho for test-retest reliability was 0.98 (p < 0.001); Cronbach's alpha 0.95. Factor analysis revealed only 1 factor with an Eigenvalue >1 [3.25]. MRS was strongly correlated with the Roland Morris Questionnaire (r = 0.91), and slightly correlated with the Finger Floor Distance (r = 0.23).
