Effects of Open-label Placebos Administered Through Telehealth on COVID-related Stress, Anxiety, and Depression

Michigan State University·interventional·Posted Sep 5, 2021·Updated Mar 13, 2024

In Brief

A clinical study evaluating Non-Deceptive Placebo for Stress and 2 related conditions. Completed, enrolled 64 participants across 1 site.

Detailed Summary

This project aimed to test the efficacy of a telehealth-administered placebo without deception intervention on stress, anxiety, and depression related to the COVID-19 pandemic. Participants were randomized into two groups (open-label placebo vs. no-treatment control). All participants received information on the impact of COVID-19 on psychological health. Participants in the open-label placebo group were instructed to watch an informational video on the beneficial effects of placebos without deception, remotely interact with an experimenter, and take open-label placebo pills twice a day for two weeks. Participants in the no-treatment control group did not receive any intervention. Instead, participants met with an experimenter and reported on their psychological and physical health. The investigators predicted that the placebo without deception group would exhibit substantially reduced stress, depression, and anxiety compared to a no-treatment control group.

Interventions

Non-Deceptive Placebobehavioral

The placebos were ordered through Amazon from Zeebo® (Zeebo, Zeebo Effect, LLC, South Burlington, Vermont, USA). The placebos in this study were blue and white capsules containing Microcrystalline cellulose (an inert fiber). Ingredients include ones that are typically used to make pills including silica, gelatin, titanium dioxide, red #3 food coloring, and blue #1 food coloring. Placebo capsules were free of any active ingredients. These bottles were not branded specifically for the experiment, including the brand name ("Zeebo Relief"), description of the contents, directions, and a disclaimer. The investigators chose to not include a custom label for transparency and in order to increase "non-deceptive" placebo effects. Participants were instructed to take two pills a day, one in the morning and one in the evening.
