Optimize Low Back Pain

The objective of this study is to improve health care for patients with chronic LBP and increase the likelihood that patients obtain outcomes that matter most to them. The investigators will accomplish our goal using a sequential multiple randomization (SMART) design comparing the effectiveness of Phase 1 (PT v. CBT) treatments for patients with chronic LBP; and among patient non-responsive to Phase I treatment, compare the effectiveness of Phase II treatments (switching to PT or CBT v. mindfulness). Effectiveness will be based on patient-centered outcomes. Sub-aims will compare main effects of Phase 1 and 2 treatment options and the sequencing effects of different treatment combinations.
