 This study found that Singaporeans have been adopting preventive behaviors related to COVID-19 despite the unprecedented severity of the pandemic. These behaviors are consistent with government recommendations and include avoiding social gatherings, staying away from crowded places, wearing face masks, and limiting contact with people. Additionally, this study found that respondents who perceived higher risk of contracting COVID-19 had greater trust in government responses and felt more confident in their ability to protect themselves were more likely to engage in these behaviors. Furthermore, older, highly educated, anxious, and married respondents were also more likely to adopt preventive behaviors. To successfully encourage appropriate preventive behaviors, public health messages should emphasize response efficacy, increase self-efficacy, and promote trust in governmental response.
