The Relationship Between Social Media Use and Beliefs in Conspiracy Theories and Misinformation.

Numerous studies find associations between social media use and beliefs in conspiracy theories and misinformation. While such findings are often interpreted as evidence that social media causally promotes conspiracy beliefs, we theorize that this relationship is conditional on other individual-level predispositions. Across two studies, we examine the relationship between beliefs in conspiracy theories and media use, finding that individuals who get their news from social media and use social media frequently express more beliefs in some types of conspiracy theories and misinformation. However, we also find that these relationships are conditional on conspiracy thinking--the predisposition to interpret salient events as products of conspiracies--such that social media use becomes more strongly associated with conspiracy beliefs as conspiracy thinking intensifies. This pattern, which we observe across many beliefs from two studies, clarifies the relationship between social media use and beliefs in dubious ideas.

Understanding Chinese international students' perception of flu vaccination on U.S. college campuses.

Objective: This study examines Chinese international students' underlying beliefs and overall perception of the flu vaccination to inform effective health promotion efforts on U.S. college campuses. Participants: Data were collected in March 2020. Participants (N = 189) were recruited via email at a southeastern university in the U.S. Methods: Incorporating theory recommendations and recent vaccine-related research findings, this study designs a Four-Factor Measurement Model through confirmatory factor analysis (CFA) to examine Chinese international students' perception of flu vaccination. Results: Chinese international students' health beliefs, particularly their perceived susceptibility of the influenza virus, was the most important factor to explain their perception of flu vaccination. While normative beliefs were the least influential factor to account for Chinese international students' perception of flu vaccination, these students valued healthcare providers' opinions immensely. Conclusions: This study suggests the Four-Factor Measurement Model will help measure Chinese international students' perception of flu vaccination and can be applied to future vaccine-related research.
