Effect of Mindfulness-Based Stress Reduction vs Cognitive Behavioral Therapy or Usual Care on Back Pain and Functional Limitations in Adults With Chronic Low Back Pain: A Randomized Clinical Trial.

The short version

This randomized clinical trial with 342 adults explored whether an eight-week mindfulness-based stress reduction (MBSR) program — training in meditation, body awareness, and yoga — could ease chronic low back pain as effectively as cognitive behavioral therapy (CBT), a well-established talk-therapy approach that helps people change pain-related thoughts and behaviors. Both interventions govern how the nervous system processes and responds to persistent pain signals, but through different mechanisms: MBSR through non-judgmental present-moment awareness, CBT through restructuring unhelpful thought patterns. Participants had lived with low back pain for an average of over seven years. Adults aged 20 to 70 (mean 49, two-thirds women) with pain lasting at least three months were randomly assigned to MBSR, CBT, or usual care. Both active groups met weekly for eight two-hour sessions — MBSR practiced body scans, sitting and walking meditation, and gentle yoga, while CBT focused on identifying unhelpful thoughts, relaxation training, and pacing daily activities. Improvement was measured with the Roland Disability Questionnaire (a 23-item scale of pain-related function) and a 0-10 pain-bothersomeness rating, checked by blinded interviewers at 8, 26, and 52 weeks. At the six-month mark, 61% of the MBSR group and 58% of the CBT group showed clinically meaningful improvement in function, compared with 44% of the usual-care group (a statistically significant difference, p=0.04, meaning the pattern was unlikely to occur by chance). Pain bothersomeness improved meaningfully for 44% of MBSR participants and 45% of CBT participants, versus 27% on usual care (p=0.01). MBSR was about 1.4 times more likely than usual care to produce meaningful functional improvement, and both active treatments held their advantage a full year later. On mood measures, CBT edged out MBSR at some points, though both beat usual care through six months. Roughly 3 in 10 MBSR participants and 1 in 10 CBT participants reported a temporary increase in discomfort — most often stiffness or soreness from yoga or relaxation exercises — with no serious safety concerns in either group. The trial suggests MBSR works about as well as CBT for chronic low back pain, giving people a second evidence-based option beyond conventional pain therapies. Only about half of participants attended six or more of the eight sessions, hinting the benefits may not require full completion. The study was conducted at a single US healthcare system among a fairly well-educated population, so how the findings translate to other settings, or to CBT delivered one-on-one rather than in groups, is not yet known. The authors call for further work on cost-effectiveness and long-term durability beyond one year.

Key findings

• In a trial of 342 adults with chronic low back pain lasting an average of seven years, an eight-week mindfulness-based stress reduction (MBSR) program combining meditation, body awareness, and yoga produced functional improvement in 61% of participants after six months, compared with 44% who received usual medical care alone.
• MBSR performed about as well as cognitive behavioral therapy (CBT), a widely recommended talk-therapy approach for chronic pain, with no statistically significant difference between the two active treatments on either functional improvement or pain bothersomeness.
• Benefits from both MBSR and CBT were still present a full year after the trial began, suggesting the skills learned in these programs may have lasting effects rather than fading once formal sessions end.
• Only about half of participants attended six or more of the eight scheduled sessions, yet meaningful improvements were still observed at the group level, suggesting some benefit even with partial program completion.
• Mild, temporary increases in discomfort, most often from yoga poses or relaxation exercises, were reported by about 3 in 10 MBSR participants and 1 in 10 CBT participants, with no serious adverse events in either group.
