Brief summary (from the registry)

This study aims to evaluate whether the reduction of the daily morphine equivalent dose (MED) in patients with subacute and chronic pain can be decreased with an open-label placebo (OLP) intervention in comparison to an electronic monitoring (EM) control group. The participants will receive the intervention (OPL or EM) over the duration of six weeks. Diverse psychological and health measures will be assessed with questionnaires over the course of the intervention. Furthermore, evaluation outcomes, qualitative outcomes and safety outcomes will be assessed. It is hypothesized that the OLP-intervention group in comparison to the EM-control group will have a significantly lower consumption of MED over the course of the study. Furthermore, this study aims to evaluate whether the OLP intervention can reduce opioid withdrawal symptoms in comparison to the control group.
