Mindfulness And Placebo for Pain (MAPP) Study

The standard 8-week MBSR program will be led by certified MBSR instructors from the UCSD Center for Mindfulness. The program content will consist of a variety of mindfulness and meditative techniques, such as sitting meditation, body scans, and mindful yoga. Participants will engage in weekly sessions via Zoom, participation in group discussions, and honing their other mindfulness skills. Throughout the program, participants will be instructed to commit to a daily mindfulness meditation practice lasting approximately 45 minutes, at least 6 days a week.

The placebo pills will be size #1 capsules filled with (1) microcrystalline cellulose, a common inert excipient for pharmaceuticals, and (2) 25 mg riboflavin tracer. Participants will be informed that the placebo pills are inactive substances, like sugar pills, and contain no active medication. Then, they will watch a brief introduction video which will cover four main discussion points: (1) the placebo effect can be powerful and can have beneficial effects for diverse symptoms, (2) the body can respond to taking placebo pills automatically despite the knowledge that it is placebo (e.g., Pavlov's dogs), (3) a positive attitude or expectation can be beneficial but is not necessary, and (4) taking the pills faithfully throughout the intervention period is critical.

This condition involves a combination of interventions, where participants will receive both MBSR and OLP treatments.
