Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Subjects are asked to immerse themselves in the scenario's before answering what their most likely behaviour would be: a) go to a test facility b) use a LFT c) wait and see or 4) no test. Participants who didn't choose the test facility on day 1 were presented with the same vignette on day 3 with unchanged symptoms, and were asked their most likely behaviour again.
After assessing the scenario's, participants fill in a questionnaire assessing demographics, behavioural determinants related to test behaviour, vaccine status, current symptoms and previous experience with Corona and testing.
The primary outcomes is defined as the average strategy sensitivity over time and therefore the chance of detecting a Covid-infection. Average strategy sensitivity is calculated by converting the choice of testing behaviour into the corresponding sensitivity score (PCR =1, LFT day 1 = .8, LFT day 3 = .7, wait and see and no test = 0), averaged over four scenario's.
Our primary hypothesis is:
1. Adjusting the governmental testing advice will lead to a higher strategy sensitivity.
In follow-up analysis we will explore the following hypothesis:
2. Availability of LFT at home will lead to a higher strategy sensitivity.
3. The type of corona related symptoms (mild or severe) are predictive of the type of test used.
4. When confronted with a new incidence of corona-related symptoms over time, strategy sensitivity will decline.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Customised advice + LFT available at home
Respondents will see an altered testing advice in text and picture in which they are allowed to use LFT with corona related symptoms.
Respondents will informed in writing that they don't currently have any LFT available at home.
Customised testing advice
Customised advice: With Corona related symptoms, get tested at a test facility. If this isn't possible, use a Lateral Flow test.
LFT available
LFT availability: Enough lateral flow tests available at home
Customised advice + No LFT available at home
Respondents will see an altered testing advice in text and picture in which they are allowed to use LFT with corona related symptoms.
Respondents will informed in writing that they don't currently have any LFT available at home.
