COVID-19 preventive behaviors, health literacy, and information: a survey of information-evaluation and decision-making skills in Japanese adults (Preprint)
BACKGROUND Health literacy is important for the prevention of COVID-19. Research in Japan shows that health literacy is related to skills in evaluating information and decision making (not necessarily limited to health information). Such basic skills are important, particularly when individuals encounter new health issues for which there is insufficient evidence. OBJECTIVE This study aimed to determine the extent to which COVID-19 preventive behaviors were associated with health literacy and skills in evaluating information and making decisions. METHODS An online questionnaire survey was conducted using a Japanese Internet research company. A total of 3,914 valid responses were received. The measures comprised eight items on COVID-19 preventive behaviors, health literacy items (European Health Literacy Survey Questionnaire), five items on information evaluation, and four items on the decision-making process. Pearson correlations between these variables were calculated. Multivariate analyses were also conducted using COVID-19 preventive behavior score as a dependent variable. RESULTS COVID-19 preventive behaviors were significantly correlated with health literacy, information evaluation, and the decision-making process (.23, .24, .30, respectively). The multiple linear regression analysis results showed that the standardized regression coefficients for each were .11, .13, and .18; the highest value was for decision-making skills. CONCLUSIONS Although comprehensive health literacy is necessary for COVID-19 preventive behaviors, the skills to evaluate a wide range of information and to make appropriate decisions are no less important. Opportunities for people to acquire these skills should be available at all times.
