They literally have you go through "Worry Less, Live More: The Mindful Way Through Anxiety Workbook", so it's at least building off of it in some way. Mindfulness with a pain-oriented focus is not new.

Looking at their patient groups on Table 1, it seems MBSR and Usual Care had participants with more spinal injections and surgical interventions. MBSR and Usual Care have higher "Pain bothersomeness" scores and "Roland Disability Questionnaire Scores" at the start.

It's a very small-scale pilot study. I am very skeptical it's not a ploy to try to sell his books.

MBSR teacher (well, learning!) here. I would also be skeptical based purely on the sample size, but MBSR as a treatment is pretty well researched and documented. It's been around for 40+ years and there is fairly extensive supporting research [1].

So - I wouldn't be in any way surprised if there are other related treatments which have high levels of efficacy...

Agreed, sample arms were n=11 or 12.
