Plain English summary of protocol

Background and study aims
The purpose of this study is to understand how people respond to COVID-19 public service announcements (PSA) advocating wearing a mask and staying at home. The study will test whether adding a short phrase that links compliance as being consistent with the subject's identity as a Christian or someone motivated by the economy will increase the likelihood of complying with the guidance.

Who can participate?
Amazon Mechanical Turk members holding an Amazon Masters classification

What does the study involve?
The study will be conducted over the internet using the Amazon Mechanical Turk (MTurk) crowdsourcing marketplace. The study will first collect demographic information, then ask about the extent to which participants identify with the economy and as a Christian, and the extent to which they trust three PSA sources: the US Public Health Service (PHS), the Senate Chaplain, and the US Chamber of Commerce (CoC). Then, participants will be shown two PSA about COVID-19 and ask will be asked to provide their likelihood of complying with the public health guidelines provided by each PSA. One PSA will be a control PSA from the PHS and the other will be framed with a Christian identity from the Senate Chaplain, or framed with the economy identity from the CoC (this will be aligned with the participant answers from the first part of the study to match if the subject trusts the source and holds the identity). Participation in the study will take 5-8 min.

What are the possible benefits and risks of participating?
There are no benefits to participants anticipated, however, participants will be paid 50 cents for participating. It is hoped that the study will provide information that will help scientists in the future.

There are no risks to participants anticipated, however, some participants may feel uncomfortable reading about COVID-19 or answering questions about it.

Study objectivesDoes framing a PSA using a Christian social identity or an economically-motivated personal identity increase the likelihood of compliance with COVID-19 guidelines by individuals who hold those identities?

InterventionThe study will be conducted over the internet using the Amazon Mechanical Turk (MTurk) crowdsourcing marketplace. The study will first collect demographic information, then ask about the extent to which participants identify with the economy and as a Christian, and the extent to which they trust three PSA sources: the US Public Health Service (PHS), the Senate Chaplain, and the US Chamber of Commerce (CoC).

Participants will receive two COVID-19 public service announcements (PSAs), one advocating wearing a mask and one calling on people to stay at home, in random order. The treatment order and assignment of which PSA was the control and which was the treatment will be randomized in Qualtrics. One PSA was a control PSA with information purportedly from the US Public Health Service and the other was an identity-framed PSA (either Christian-framed or economics-framed). After reading each PSA, participants reported to what extent they would engage in the advocated behavior. Participation in the study will take 5-8 min.
Intervention typeBehavioural
Primary outcome measureLikelihood of complying with Public Service Announcement measured using seven items adapted from prior research delivered via the online platform immediately after viewing the PSA
