Effects of Health Literacy in the Fight Against the COVID-19 Infodemic: The Case of Japan

Correlates of COVID-19 conspiracy theory beliefs in Japan: A cross-sectional study of 28,175 residents

BACKGROUND

The COVID-19 pandemic was associated with an increase in conspiracy theories worldwide. However, in Japan, the prevalence of COVID-19 conspiracy beliefs has remained unclear. This study aimed to estimate the prevalence and correlates of COVID-19 conspiracy beliefs using a survey of 28,175 residents of Japan aged 16-81 years old.

METHODS

A cross-sectional self-administered survey was conducted from September to October 2021. To assess the number of COVID-19 conspiracy beliefs, we used three questions from the Oxford Coronavirus Explanations, Attitudes, and Narratives Survey. Independent variables included general vaccine conspiracy beliefs, sociodemographic variables, information sources for COVID-19, trust in authorities, and fear of COVID-19.

RESULTS

After applying sampling weights and imputation, the estimated prevalence of holding at least one COVID-19 conspiracy belief was 24.4%. From a linear regression model, several factors were independently associated with conspiracy beliefs. Notably, people with the lowest level of education (lower secondary school) endorsed fewer COVID-19 conspiracy beliefs (B -0.089, vs. upper secondary school). Furthermore, higher socioeconomic backgrounds-such as higher income, higher wealth, and regular employment-were associated with endorsing conspiracy beliefs. Only 37.3% of respondents trusted the government of Japan, but paradoxically, trust in the government was positively associated with conspiracy beliefs (B 0.175, vs. distrust).

CONCLUSIONS

COVID-19 conspiracy beliefs can be prevalent in about a quarter of the residents of Japan. Certain groups are more likely to endorse conspiracy beliefs, and targeting interventions towards these groups might be efficient in stemming the spread of conspiracy beliefs.

Gist Knowledge and Misinformation Acceptance: An Application of Fuzzy Trace Theory

Applying fuzzy trace theory to misinformation related to COVID-19, the present study (a) examines the roles of gist knowledge in predicting misinformation acceptance, and (b) further examines whether a gist cue in fact checking scales affects the level of gist knowledge. Study 1 (a survey) showed that categorical gist knowledge was negatively related to misinformation acceptance, whereas ordinal gist knowledge was not, when both types of knowledge were included in the model. In addition, Study 2 (an experiment) showed that fact checking scales containing a categorical gist cue resulted in greater categorical gist knowledge.

Vaccine Hesitancy and Susceptibility to SARS-CoV-2 Misinformation in Japanese Youth: The Contribution of Personality Traits and National Identity

During the pandemic, the Japanese government drew upon the cultural concept of jishuku, or personal self-constraint, requesting that individuals accept responsibility for their behaviors and consider minimizing the potential negative impact on others. While the jishuku approach to pandemic management rests upon the established and persuasive influence of cultural norms, variability in adherence can be expected according to age. This article documents an investigation into factors impacting vaccine hesitancy and susceptibility to SARS-CoV-2 misinformation among Japanese youth. The point of departure is the belief that attitudes and behaviors, such as those underpinning the jishuku approach to pandemic management, arise from within a relational framework. Therefore, developmental characteristics, such as personality traits, and in-group affinity attachments, such as facets of national identity, can be expected to function as predictors of health attitudes and behaviors. The tested structural model of hypothesized interactions accounted for 14% of the observed variance in vaccine hesitancy and 20% in susceptibility to SARS-CoV-2 misinformation. With the inclusion of gender, political ideology, and trust in government SARS-CoV-2 response as control variables, the respecified model increased the amount of variance observed in vaccine hesitancy to 30% and to 25% in susceptibility to SARS-CoV-2 misinformation. The outcomes are discussed in relation to the communication of coherent public health discourse relative to personality traits and facets of national identity.

Health Literacy, Misinformation, Self-Perceived Risk and Fear, and Preventive Measures Related to COVID-19 in Spanish University Students

The "infodemic" is one of the main obstacles in the fight against the COVID-19 pandemic. In order to face it, health literacy (HL) is essential since it allows for knowledge about COVID-19 and the practice of preventive measures to be fostered. This is especially relevant in university students due to their idiosyncrasy. This study aims to evaluate the level of HL related to COVID-19 (HLC), risk perception, misinformation, and the attitudes and behaviors adopted to prevent the spread of coronavirus in Spanish university students. An online questionnaire was administered to 499 Spanish university students. The HLC index presented a mean of 33.89 out of 50; a total of 63.8% had an inadequate level of HLC. They practiced a mean of 7.54 out of 9 preventive behaviors, and the mean knowledge score was 10.40 out of 13. The HLC showed significantly different scores for the degree, the practice of preventive measures, and some sources of information. The level of HL correlates with the adoption of preventive measures. The higher the severity and perceived susceptibility, the more preventive measures are taken by the students. Therefore, there is a need to strengthen the HL skills of university students and address the dissemination of misinformation. Although caution should be taken when generalizing these results due to the limitations inherent within a cross-sectional study and the convenience sampling, our results can guide the establishment of health education strategies and policies for the management of the infodemic in pandemic situations, according to this target population.
