TL;DR. MBSR produces reliable small-to-moderate reductions in anxiety, stress, and chronic-pain symptoms across hundreds of RCTs.

The program

MBSR is an eight-week, 26-hour program Jon Kabat-Zinn developed at UMass Medical Center in the 1970s. It combines formal meditation (body scan, sitting meditation, mindful movement) with informal practice — bringing mindful attention to daily activities.

It is probably the most-studied meditation intervention in existence. The evidence is broad and generally favourable, with some caveats about effect size.

Relevant research: Kabat-Zinn, 2003 (Clinical Psychology: Science and Practice).

The effect sizes

Across hundreds of RCTs and several meta-analyses, MBSR produces small-to-moderate effect sizes on anxiety, stress, and chronic-pain outcomes. Effects are stronger when the intervention is delivered in its full eight-week form with a qualified teacher.

App-delivered variants typically show smaller effects than the full program, partly because people complete less practice.

Relevant research: Kabat-Zinn, 2003 (Clinical Psychology: Science and Practice).
