To compare the contribution of physical, psychological and social indicators to predicting disability after one year between consulters with low back pain (LBP) of less than 3 months duration and more than 3 months duration. Data from two large prospective cohort studies of consecutive patients consulting with LBP in general practices were merged, with disability measured by the Roland Morris Disability Questionnaire (RMDQ). There were complete data for 258 cases with acute/subacute LBP and 668 cases with chronic LBP at 12 months follow-up. Univariate and adjusted multivariate regression analyses of various potential prognostic indicators for disability at 12 months were carried out.Purpose
