Education level significantly correlated with COVID-19 knowledge and preventive behaviors. Job status also showed a significant association with participants&#39; understanding and actions regarding COVID-19. Regression analyses revealed that higher levels of knowledge (&beta;=0.5, p=0.001) and anxiety (&beta;=0.182, p=0.001) were linked to increased engagement in preventive behaviors.</span></span><br> <span style="font-size:9pt"><span minion="" pro="" style="font-family:"><b>Conclusion</b><b><span style="font-size:11.0pt"><span new="" roman="" style="font-family:" times="">: &nbsp;</span></span></b>This study focused on COVID-19 survivors, finding that anxiety may serve as a motivating factor for engaging in preventive behaviors.
