Registration Number
NCT04758299
Lead Sponsor
Barry Dewitt
Brief Summary

To test competing sets of information for consumers on how to interpret hypothetical SARS-CoV-2 home test kit results and whether they report plans to take CDC-recommended actions to protect themselves and others given their test results and two critical aspects of their clinical context: symptoms, recent close exposures. Participants will be randomized to receive either information from the FDA authorized Ellume home test kit (the first kit authorized for over the counter use) for what actions to take for a negative or positive COVID-19 test (usual care) or a decision science-based design of similar length (intervention).

Detailed Description

To test competing sets of information for consumers on how to interpret hypothetical SARS-CoV-2 home test kit results and whether they report plans to take CDC \[Centers for Disease Control\]-recommended actions to protect themselves and others given their test results and two critical aspects of their clinical context: symptoms, recent close exposures. Participants will be randomized to receive either information from the FDA authorized Ellume home test kit (the first kit authorized for over the counter use) for what actions to take for a negative or positive COVID-19 test (usual care) or a decision science-based design of similar length (intervention).

Participants will be randomized to receive either information from the FDA authorized Ellume home test kit for what actions to take for a negative or positive COVID-19 test (usual care) or a decision science-based design of similar length (intervention). They will be given time to read the documents and the opportunity to download a full "instructions for use" document (the FDA authorized for the ELLUME test kit). They will then be randomized to one of four conditions, asking them to imagine a clinical context: a person with no symptoms and no close COVID-19 contact, no symptoms and close contact,

1. Very difficult

2. Difficult

3. Neutral

4. Easy

safe practicesday 1

Change in intent to practice standard public health practices to reduce COVID-19 transmission (hand washing, social distancing, masks) - question asked before and after seeing test result

What else do you think Jamie should do to protect himself and others from COVID-19? \[choose: all of the time, most of the time, some of the time, a little of the time, none of the time\] In general

1. Wash hands often

2. Avoid close contact with people who seem sick (e.g., cough, sneeze, fever)

3. Stay home

Outside your home

4. Try to avoid crowds

5. Wear a mask when around others

6. Keep 6 feet from others

7. Avoid contact with anyone

helpfulness of information for what to do given negative test resultday 1

How helpful was the information for what to if test was negative

The information helped me know what to do if test result is negative

a. Strongly agree

1. Agree

2. Neutral

3. Disagree

4. Strongly disagree

Assess effect of the FDA authorized description of test accuracyday 1

According to the test's FDA-authorized label, a clinical study conducted in the USA in 2020 showed that the test "correctly identified 96% of positive samples and 100% of negative samples in patients with symptoms. In people without symptoms the test correctly identified 91% of positive samples and 96% of negative samples."

Based on this information, if Jamie has COVID now, what is the chance that the test will be wrong and say that he does not?
