PurposeThe Roland–Morris Disability Questionnaire (RMDQ) is one of the most recommended questionnaires to assess disability. Some previous studies support the assumption that the RMDQ is a unidimensional measure; however, recent studies have suggested that this measure has more than one domain and should be considered as a multidimensional scale. Therefore, the aim of this study was to analyse the structure of the RMDQ in a large sample of patients with low back pain using two different statistical approaches.
