Official title
Optimizing Open Placebos for Chronic Pain Patients
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of this clinical trial is to examine the effect of rationale condition when taking open-label placebos on pain by 1) comparing each rationale to the no rationale control condition and the no treatment control condition; and 2) comparing the rationale conditions to each other. We also aim to examine the effect of rationale condition on prescription opioid use by 1) comparing each rationale to the no rationale control condition and the no treatment control condition; and 2) comparing the rationale conditions to each other. This study will include patients with chronic low back pain. The main question it aims to answer is: How do rationales influence the effects of open-label placebos? Researchers will compare different rationales given when taking an open-label placebo and a no-treatment group and a no rationale group taking OLPs.
