Location details:
United States and Italy
Unit of observation:
Individual
Sample size:
5,759 (3,100 USA + 2,659 Italy)
Inclusion/exclusion:
After providing informed written consent, respondents read an unrelated vignette to assess their attention. Those who did not answer a comprehension question correctly could not proceed with the study and exited the sample.
Randomization procedure:
At the subject level, we randomized respondents at equal rates to a Placebo Control, where they read a message unrelated to the topic of the experiment, a Masks Protect You treatment that explains how masks stop some percentage of SARS-CoV-2 virus particles in the air from being inhaled by healthy people, and a Masks Protect Others treatment that explains how masks stop some percentage of SARS-CoV-2 virus particles from being expelled into the air by sick people.
Treatment:
Our core randomized treatments allow us to test whether beliefs about mask efficacy and the mask wearing behavior of others as described in a vignette affect one’s own mask wearing and one’s willingness to encourage mask wearing by others.
Treatment administration:
Web delivered
Outcome measures:
beliefs about masks protecting you,beliefs about masks protecting others,behavioral intentions,third party judgment
