Credibility of misinformation source moderates the effectiveness of corrective messages on social media.

To examine how different features of corrective messages moderate individuals' attitudes toward misinformation on social media, a 2 (misinformation source credibility: high vs low) × 2 (corrective message source: algorithmic vs peer correction) × 2 (correction type: factual elaboration vs simple rebuttal) between-subjects experiment was conducted. To reduce perceived credibility and respondents' attitudes toward the misinformation, peer corrections were more effective than algorithmic corrections for misinformation from a source with lower credibility; for misinformation from a highly credible source, the superiority effect of peer corrections was still significant on perceived credibility but not on respondents' attitudes toward the misinformation. For the fact-checking tendency, we did not find a robust effect about how different features of corrective messages interacted. Our findings provide important insights into message design in combatting misinformation on social media.

Adopting the risk information seeking and processing model to examine the impact of personality on vaccination intentions in Taiwan.

Using the risk information seeking and processing model, this study examined how five personality traits-extraversion, neuroticism, conscientiousness, openness to experience, and agreeableness-influenced individuals' information-seeking behaviors and vaccination intentions. An online survey was administered by a reputable polling company commissioned by this study. The survey employed age, education, gender, and income as distinct strata for sampling, which resulted in 1100 valid questionnaires. The following five conclusions were drawn from the data analysis: (1) Of the five personality traits, two-extraversion and conscientiousness-exhibited a notable impact on individuals' information-seeking behaviors and vaccination intentions. Individuals with the remaining three personality traits-neuroticism, agreeableness, and openness to experience-demonstrate either passive or no information-seeking behaviors on COVID-19. (2) Conscientiousness was the only personality trait linked to increased awareness of COVID-19 characteristics. Moreover, conscientious individuals were inclined to avoid depending on ISNs to seek COVID-19 information and developed vaccination intentions. In contrast, individuals high in agreeableness heavily depended on ISNs for COVID-19 information to initiate information-seeking behaviors. Meanwhile, individuals high in extraversion relied on two variables-affective responses and ISNs-to begin their information-seeking behaviors. (3) Respondents' perceptions of COVID-19 characteristics and their affective responses did not positively influence their perceived information insufficiency directly; instead, both needed to be mediated by ISNs to initiate their information-seeking behaviors. (4) In contrast to the two variables-perceived COVID-19 characteristics and affective responses-this study found that ISNs regarding COVID-19 played a more substantial role in shaping respondents' information-seeking behaviors and vaccination intentions. (5) Unexpectedly, openness to experience was found to have no impact on information-seeking behaviors during the COVID-19 pandemic.

Channels Adopted for Information Seeking during COVID-19: Comparing Social Media with News Media and Interpersonal Communication in Taiwan.

By adopting niche theory, this study compared social media with news media and interpersonal communication regarding their capabilities in satisfying people's information needs of daily use, surveillance, convenience, and information quality during the outbreak of COVID-19. Two methods were adopted to collect data for this study: the first was to conduct 20 intensive interviews, and the second was to administer an online survey by contracting a professional polling company with a panel of 8.8 million members. The stratified random sampling method was used to acquire a representative sample, from which 1100 valid questionnaires were obtained. The results showed that: (1) Social media were superior to traditional news media in terms of its convenience. However, several new types of online news, such as Yahoo news, were able to compete with social media for convenience. (2) Interpersonal communication did not outperform in satisfying individuals' needs for the four gratifications. Nevertheless, interpersonal communication plays the role of social support for individuals.

Information Seeking and Processing during the Outbreak of COVID-19 in Taiwan: Examining the Effects of Emotions and Informational Subjective Norms.

Adopting the model of risk information seeking and processing (RISP) as a theoretical framework, the objective of this study was to investigate the factors that prompted individuals' information-seeking and -processing behaviors during the COVID-19 pandemic in Taiwan. There were two unique aspects in this study: one was to adopt specific emotions to investigate the impact of negative emotions, and the other was to examine the effect of informational subjective norms (ISNs) on information-seeking and -processing behavior. An online survey was conducted by a professional polling company, and a stratified random sampling method was employed, using gender, age, education, personal income, and residential areas as strata to select participants. This study obtained 1100 valid questionnaires. The results showed that (1) risk perception did not exert any significant impacts on respondents' perceived information insufficiency; (2) risk perception exerted a powerful impact on respondents' ISNs, which, in turn, positively affected their information insufficiency; (3) the respondents who experienced fear were found to have a high probability of using a systematic-processing mode, while the respondents who experienced anger were more likely to adopt a heuristic-processing mode to process information; and (4) the use of a systematic-processing mode was positively associated, while the use of a heuristic-processing mode was negatively associated, with information-seeking behavior.

Exploring Psychological Factors for COVID-19 Vaccination Intention in Taiwan.

To underpin the psychological factors for vaccination intention, we explored the variables related to positive and negative attitudes toward COVID-19 vaccination in Taiwan. The data were collected via an online survey platform with a sample size of 1100 in April 2021. We found that people's interpretations of the origin of the virus were relevant. People who tended to believe that the virus was artificially created felt powerless and were more concerned about the possible side-effects of the vaccines, which was negatively associated with their vaccination intention. The source of vaccine recommendation was found to be relevant to vaccination intention. People's vaccination intention was highest if the vaccines were recommended by health professionals, followed by friends and the government, and then mainstream media and social media. The analysis of the demographic variables showed that men tended to be more receptive to vaccines than women. Our findings should provide insights into developing communication strategies to effectively promote vaccination intentions.

Lifestyles and gratifications obtained from news: Comparing science news with health news and political news.

This study adopted uses and gratifications theory to examine the relationships among lifestyles, gratifications obtained, and the use of science, political, and health news. Two methods were adopted, the first of which was to conduct 23 interviews. The second method was a nationwide telephone survey that obtained 949 valid questionnaires. The data analysis yielded three conclusions: (1) among the four types of variables, gratifications obtained were the most powerful predictors for the use of the three types of news; (2) users and nonusers of science news or health news were differentiated mainly by lifestyles, while users and nonusers of political news were differentiated mainly by mass media use; and (3) users of the three types of news differed greatly. Science news users used new media, and were likelier to have a lifestyle of learning and self-development, while political and health news users preferred and trusted traditional media sources, the latter seeking a lifestyle of pleasure.
