| Popis: | ObjectiveAlthough widespread testing for SARS-CoV-2 is in place, little is known about how well the public understands these results. We aimed to provide a comprehensive overview of the general public’s grasp of the accuracy and significance of the results of the swab test.DesignWeb-based behavioural experiment.SettingItaly during the April 2020 lockdown.Participants566 Italian residents.Main outcome measuresParticipants’ estimates of the SARS-CoV-2 prevalence; the predictive and diagnostic accuracy of the test; the behavioural impact of (positive vs negative) test results; the perceived usefulness of a short-term repetition of the test following positive or negative results; and rankings of causes for false positives and false negatives.ResultsMost participants considered the swab test useful (89.6%) and provided predictive values consistent with their estimates of test diagnostic accuracy and infection prevalence (67.0%). Participants acknowledged the effects of symptomatic status and geographical location on prevalence (all pConclusionsWhile some aspects of the swab for SARS-CoV-2 are well grasped, others are not and may have a strong bearing on the general public’s health and well-being. The obtained findings provide policymakers with a detailed picture that can guide the design and implementation of interventions for improving efficient communication with the general public as well as adherence to precautionary behaviour. |
