BACKGROUND

COVID-19 preventive perceptions and behaviors, especially among US millennials, are an important means by which the pandemic can be slowed and negative health outcomes can be averted.

OBJECTIVE

This manuscript aims to advance knowledge on COVID-19 preventive perceptions and behaviors and their main predictors, including digital health information–seeking behavior (HISB), political party identification, and COVID-19 testing status.

METHODS

Two cross-sectional online surveys of US millennials were conducted from April 10 to 14, 2020 (N=274) (ie, Study 1), and from April 27 to May 7, 2020 (N=1037) (ie, Study 2). In the regression models, dependent variables included preventive behaviors (eg, wearing a face mask and social distancing) as well as four preventive perceptions: severity (ie, a person’s conception of the seriousness of COVID-19), susceptibility (ie, a person’s conception of the likelihood of being infected with COVID-19), self-efficacy (ie, a person’s perception that he or she can wear a face mask and perform social distancing to prevent COVID-19 infection), and response efficacy (ie, a person’s perception of whether wearing a face mask and social distancing can prevent COVID-19 infection). Key independent variables included digital HISB for self, digital HISB for another person, political party identification, and COVID-19 testing status.

RESULTS

Millennials reported lower levels of perceived susceptibility than the other three preventive perceptions (ie, severity, self-efficacy, and response efficacy), as well as fairly high levels of preventive behaviors. Unlike HISB for another person, digital HISB for self was positively associated with preventive perceptions and behaviors. In Study 1, respondents with higher levels of digital HISB for self had significantly higher perceptions of severity (<i>β</i>=.22, <i>P</i>&lt;.001), self-efficacy (<i>β</i>=.15, <i>P</i>=.02), and response efficacy (<i>β</i>=.25, <i>P</i>&lt;.001) as well as, at nearing significance, higher perceptions of susceptibility (<i>β</i>=.11, <i>P</i>=.07). In Study 2, respondents with higher levels of digital HISB for self had significantly higher perceptions of severity (<i>β</i>=.25, <i>P</i>&lt;.001), susceptibility (<i>β</i>=.14, <i>P</i>&lt;.001), and preventive behaviors (<i>β</i>=.24, <i>P</i>&lt;.001). Preventive behaviors did not vary significantly according to political party identification, but preventive perceptions did. In Study 1, respondents who identified as being more Republican had significantly lower perceptions of self-efficacy (<i>β</i>=−.14, <i>P</i>=.02) and response efficacy (<i>β</i>=−.13, <i>P</i>=.03) and, at nearing significance, lower perceptions of severity (<i>β</i>=−.10, <i>P</i>=.08) and susceptibility (<i>β</i>=−.12, <i>P</i>=.06). In Study 2, respondents who identified as being more Republican had significantly lower perceptions of severity (<i>β</i>=−.08, <i>P</i>=.009). There were mixed effects of COVID-19 testing status on preventive perceptions, with respondents who had tested positive for COVID-19 having significantly higher perceptions of susceptibility in Study 1 (<i>β</i>=.17, <i>P</i>=.006) and significantly lower perceptions of severity in Study 2 (<i>β</i>=−.012, <i>P</i>&lt;.001).

CONCLUSIONS

As the largest and most digitally savvy generation, US millennials saw COVID-19 as a severe threat, but one that they were less susceptible to. For millennials, digital HISB for self, but not for another person, was critical to the development of preventive perceptions and behaviors.
