Intervention (Public)
|
Before
We plan to cross randomize the incentive amount offered and the emphasis placed on government involvement in the study on the flyers advertising the baseline survey. Individuals will see either a) a 10 dollar or incentive, or b) a 20 dollar incentive; and either a) messaging that emphasizes government involvement in the study, or b) messaging that emphasizes the involvement of academic researchers.
Flyers will be randomized at the food shelf-day level.To test what affects item non-response on potentially sensitive questions, such as those asking for health information - we hypothesize that ethical framing may encourage people to answer questions. This takes two forms, the deontological (or duty based) vs. the consequential (or cost-benefit frame). Moreover, knowing others feel the same way (regarding the obligation or benefits of providing health in-formation), may amplify the motivation. Finally, there is the possibility that providing information on norms of response might be helpful. Prior to seeing several potentially sensitive survey blocks, individuals will see either a) messaging that emphasizes the public health benefits of answering the survey questions (cost-benefit frame); b) messaging that emphasizes an individual’s responsibility to their community (duty frame); or c) no messaging. Messaging content will be randomized at the individual level.

Experimental Design (Public)
|
Before
1 Recruitment and Sampling
We are recruiting subjects through 11 food shelves in the Twin Cities area. Food shelves will place flyers (see Figure 1 and 2) advertising the baseline survey in bags of food and prepackaged meals that are distributed to food shelf users. We require all participants to be age 18 or older and to speak English or Spanish. We will use a touchless delivery systems to drop off and redeem flyers on a daily basis. Our target sample size is 1000 survey responses. We may stay in the field (i.e. oversample) food shelves that tend to serve minority individuals so that we can increase their representation in the survey.
2 Experimental Protocols
2.1. Randomization of Flyers (Unit Response)
(a) Randomly assign survey advertising flyers to food shelves stratified by bins of dates. These include Four bins over the two weeks of planned fieldwork. These include Mon, Tues, Wed for week 1 and week 2 and Thurs Fri and Sat for week 1 and week 2. The unit of analysis will be the food shelf-date as will the level of randomization. See Appendix A for flyer examples.
(b) Food shelves distribute the randomized daily flyer via food bags and prepackaged meals
2.2. Recruitment and Baseline Survey
(a) For all potential study participants, elicit a preference for English or Spanish. Those with a preference for Spanish will be given a Spanish language consent form and survey questions.
(b) Individuals provide consent.
(c) Collect demographic information
2.3. Randomization of messaging content before a sensitive survey modules (Item Response)
(a) After completing the demographics survey module, participants are randomly assigned to one of four ethical motivation messaging options; deontological, consequential, acknowledgement of racial inequities, or nothing.
(b) Participants are shown the same randomly assigned message prior to each sensitive survey module.
(c) Participants answer in survey modules 2-5 on media attitudes, health and COVID-19, and discrimination in healthcare.
2.4. Participants answer debrief questions and are prompted to get tested for COVID-19 if they have any officially recognized symptoms. Participants are also notified that they may share the survey with family and friends
2.5. Electronic gift cards are texted to participants who complete the survey to compensate them for their time.
3 Randomization Within each strata we will randomly assign food shelf dates to the four different treatments using Stata14.2 for the unit nonresponse outcomes. Robust standard errors will be used as the level of outcome is the same as the unit of randomization. For item nonresponse outcomes, we will randomize at the individual level in qualtrics.
4 Survey Messaging Content
One of the following message options will be randomly assigned to participants after completing the demographics section of the survey module.
4.1.No framing– No message displayed.
4.2.Consequential framing– "Answering the questions in this survey is an easy way that you can help improve the public health response to COVID-19 in your community."
4.3.Deonteological framing– "It is important for everyone to do their part to protect their community during the COVID-19 pandemic."
4.4.Acknowledgement of racial inequities– "COVID-19 is affecting everyone, but is hitting African American and Latinx communities particularly hard."
