SARS-CoV-2 rapid antigen point-of-care (PoC) and home tests are available to laypeople. This raises questions regarding the drivers and barriers of people’s willingness to use tests, their understanding of test results and the psychological and behavioural consequences of positive and negative test results. Four cross-sectional data collections, including survey items, open text answers and three experiments, were therefore conducted between December 2020 and March 2021, involving 4,026 German participants. The majority was willing to use PoC or home tests. People will be more likely to use tests when they are inexpensive and easy to use or when they are a necessary (given low infection rates) for obtaining access to public and social life. However, people urgently need information about what a test result means and how they should behave. Recommendations based on the present findings could make rapid testing a successful pillar of pandemic management
