Brief summary
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.
Detailed description
The study uses a sequential multiple randomization (SMART) design. The study will compare the effectiveness of common first-line treatments for chronic LBP: PT or CBT. Initial treatment will be 8 weeks duration with re-evaluation at 10-weeks after enrollment to allow time to complete treatment. At the 10-week assessment researchers will examine if the patient has responded to initial treatment using a patient-centered, validated definition of successful response based on 50% improvement in the Oswestry Disability Index (ODI). Patients who are responders to initial treatment will receive up to 2 additional sessions of the same treatment to assist transition to self-management. Non-responders will be re-randomized to a second treatment strategy of either switching to the other initial treatment (i.e., patients receiving PT switch to CBT or vice versa), or mindfulness. The second treatment phase is also 8 weeks in duration. Additional follow-ups occur 26- and 52 weeks after enrollment. The study has two co-primary outcomes; function and pain. The investigators will use the ODI, a well-validated, reliable and responsive patient-reported measure of LBP-related function recommended by the NIH Back Pain Task Force. The investigators will assess pain intensity with 0-10 ratings ('0' indicating no pain and '10' worst imaginable pain). Separate ratings are made for current, worst and best pain over the past 24 hours with an average computed to represent pain intensity. Secondary outcomes will assess dimensions of quality of life, work and healthcare utilization.
Interventions
Evidence-based physical therapy provided in 8 individual sessions including patient education, exercise instruction and manual therapy.
Evidence-based cognitive behavioral therapy provided in 8 individual sessions focused on key components of CBT; 1) identifying and monitoring maladaptive cognitions, 2) developing coping strategies (e.g., distraction, relaxation, etc.), 3) setting and working towards behavioral goals, especially focused on physical activity, and 4) focusing on self-management skills and home instruction
Mindfulness is provided in 8 individual sessions. Focus of sessions is cognitive reappraisal, positive savoring and mindfulness practices.
Includes all participants receiving any Phase I intervention
Includes all participants receiving Switching as Phase II intervention

Study design
Masking description
Participants and clinicians cannot be blind to treatment received. The investigators will remain blind to group assignment and follow-up assessments will be conducted by assessors who are blind to treatment group.
Intervention model description
Our design is a sequential multiple randomization (SMART) study design with 2 treatment phases with a possibility of 2 randomizations per participant.
Eligibility
Inclusion criteria
* Age 18 - 64 years at the time of enrollment. * Meets NIH Task Force definition of chronic LBP based on two questions: 1) How long has LBP has been an ongoing problem for you? and 2) How often has LBP been an ongoing problem for you over the past 6 months? A response of greater than 3 months to question 1, and "at least half the days in the past 6 months" to question 2 is required to satisfy the NIH definition of chronic LBP. * Healthcare visit for LBP in the past 90 days. * At least moderate levels of pain and disability requiring ODI score \>24 and pain intensity rating \> 4. * Has access to two-way video technology, such as smartphone, iPad/tablet, or laptop with webcam for telehealth visits.
Exclusion criteria
* Evidence of serious pathology as a cause of LBP including neoplasm, inflammatory disease (e.g., ankylosing spondylitis), vertebral osteomyelitis, etc. * Evidence of a specific spinal pathology as the cause of LBP including spine fracture, spinal stenosis, radiculopathy, etc. * Knowingly pregnant * Has received physical therapy for LBP; or CBT or mindfulness for any reason with a provider in prior 90 days * Currently receiving substance use disorder treatment * Any lumbar spine surgery in the past year.

Participant flow
Recruitment details
Trial enrollment began in March, 2019. In March, 2020 the trial suspended enrollments across all sites due to COVID restrictions. Enrollment resumed in April, 2021 and was completed in September, 2023.
Pre-assignment details
A total 751 participants were randomized. Three participants were determined to be false inclusions after randomization. One false inclusion was the result of not meeting the minimum disability threshold for eligibility. This participant continued in the study. The other two false inclusions were persons with medical conditions that were exclusions. These two participants did not participate in the study. Therefore study results are reported for 749 participants.
