What this research studies

You would join a group of about 340 adults with chronic pain who currently use opioid medicines. Participants are assigned to one of four groups that each get an open-label (honest) placebo plus a different short explanation about why placebos can work, including an evidence-based version and a mindfulness-focused version. Researchers will compare symptoms, pain reports, and follow-up measures over time to find which explanation leads to the greatest relief. Participation may include brief in-person sessions and phone or cell follow-up.

Who could benefit from this research

Good fit: Adults (21+) with chronic pain who are currently using opioid medications and are willing to try an honest placebo approach are the best fit.

Not a fit: People without chronic pain, those not taking opioids, or those who prefer only active drug treatments may not get benefit from this approach.

Why it matters

Potential benefit: If successful, this could offer a safer, low-risk way to reduce pain by using honest placebos paired with better explanations instead of or alongside opioids.

How similar studies have performed: Previous open-label placebo trials have shown pain reductions in some patients, but systematically comparing different explanations is a new step.
