Effects of negative serological test results for SARS-CoV-2 on attitudes and behaviour.
•
High adherence to protective measures was reported before and after the test.
•
Low level of fear from infection was reported before and after the test.
•
Changes were statistically significant but did not result in irresponsible behaviour.
•
Participants did not attribute their behaviour to the serological test results.
Abstract
Objectives
To investigate the changes in personal attitudes and behaviour before and after negative serological test results for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies.
Study design
Cross-sectional questionnaire survey.
Methods
A survey questionnaire was conducted with 200 industry workers (68% males and 32% females) who had previously tested negative for SARS-CoV-2 antibodies. The survey examined participants' self-reported general attitudes towards coronavirus disease 2019 (COVID-19), their sense of fear, as well as their behaviour towards protective measures before and after the testing.
Results
Participants perceived the disease as a severe health threat and acknowledged that the protective measures were appropriate. Respondents reported a high level of adherence to measures and low level of fear, both before and after the testing. Although these indicators were statistically significantly reduced after the test (P < 0.004), they did not result in irresponsible non-adherence behaviours. Almost all respondents attributed their application of personal protection measures to factors other than the results of serological screening.
Conclusions
Serological tests do not contribute to irresponsible non-adherence behaviours in an environment where protective measures are efficient. However, they may help reduce fear within society and working environments.
