Among back pain researchers, no consensus exists about outcome definitions or how to identify primary-care patients as not-recovered from an episode of LBP. Cut points for outcome scales have mostly been arbitrarily chosen. Theoretical models for establishing minimal important change values in studies of patients with LBP have been proposed and need to be applied to real data.Methods. A sample of 521 patients who presented with acute LBP (
