Psychological antecedents of COVID-19 information sharing within strong-tie and weak-tie networks.

Objective: This study investigates the psychological mechanisms underlying people's sharing of COVID-19 information within their strong-tie networks and weak-tie networks. Methods: A cross-sectional online survey was conducted between March and April 2020 (N = 609 Chinese adults). Measures included emotions and behavioral beliefs about COVID-19 information sharing, risk perceptions, and COVID-19 information acquisition and sharing behaviors. Multiple linear regression was performed to examine the psychological predictors of COVID-19 information sharing. Results: People were more likely to share COVID-19 information within their strong-tie networks when they experienced more negative emotions (ß = .09, p = .01) and had stronger beliefs that information sharing would promote disease prevention (ß = .12, p = .004). By comparison, negative emotions were the only significant predictor of COVID-19 information sharing (ß = .12, p = .002) within weak-tie networks (ß = .04, p = .31 for beliefs about sharing). Conclusion: People may share COVID-19 information within weak-tie networks to cope with negative emotions regardless of whether they perceive information sharing as beneficial to disease prevention. Innovation: Health educators should raise people's awareness of the psychological motivators of COVID-19 information sharing to create a healthy information environment for disease prevention.

Cultural Differences in Cancer Information Acquisition: Cancer Risk Perceptions, Fatalistic Beliefs, and Worry as Predictors of Cancer Information Seeking and Avoidance in the U.S. and China.

Cancer is one of the most common causes of death in China and the United States. Past studies found that cancer risk perceptions, fatalistic beliefs, and worry were prominent predictors of health-related behaviors. Perceived cancer risks, fatalistic beliefs, and worry were associated with cancer information acquisition in the United States. However, little is known about whether these factors played comparable roles in China. This study investigates the psychological antecedents of cancer information acquisition using data from Health Information National Trends Surveys (HINTS) in both countries. Results showed that cancer worry was negatively related to cancer information avoidance in the U.S. but positively related to information avoidance in China. Also, whereas cancer fatalistic beliefs were negatively associated with cancer information seeking in the U.S., the relationships between fatalistic beliefs and cancer information seeking exhibited more complex patterns in China. Implications for cancer communication in different cultures are discussed.

Source Trust and COVID-19 Information Sharing: The Mediating Roles of Emotions and Beliefs About Sharing.

Health information sharing has become especially important during the COVID-19 (coronavirus disease 2019) pandemic because people need to learn about the disease and then act accordingly. This study examines the perceived trust of different COVID-19 information sources (health professionals, academic institutions, government agencies, news media, social media, family, and friends) and sharing of COVID-19 information in China. Specifically, it investigates how beliefs about sharing and emotions mediate the effects of perceived source trust on source-specific information sharing intentions. Results suggest that health professionals, academic institutions, and government agencies are trusted sources of information and that people share information from these sources because they think doing so will increase disease awareness and promote disease prevention. People may also choose to share COVID-19 information from news media, social media, and family as they cope with anxiety, anger, and fear. Taken together, a better understanding of the distinct psychological mechanisms underlying health information sharing from different sources can help contribute to more effective sharing of information about COVID-19 prevention and to manage negative emotion contagion during the pandemic.

Health Information Seeking Behaviors and Source Preferences between Chinese and U.S. Populations.

This study examined similarities and differences in health information-seeking behaviors between American and Chinese people using data from the 2017 U.S. Health Information National Trends Survey (HINTS) and the 2017 China HINTS. It is one of the first studies that use comparable samples and survey instruments to make direct comparisons of the two populations' health information-seeking behaviors. Results showed that Americans (including different racial/ethnic groups in the U.S.) were more likely to actively seek health information than Chinese people. Americans were also more likely to use mediated communication as their primary sources of health information while Chinese people favored interpersonal sources. Chinese people reported lower quality of doctor-patient communication than their American counterparts. These differences between the two countries highlight the importance of using different information sources to reach specific populations, and the need to develop tailored public health intervention programs in different cultures.

Twenty-five years of hidden profiles in group decision making: a meta-analysis.

This meta-analysis summarized findings from 65 studies using the hidden profile paradigm (101 independent effects, 3,189 groups). Results showed (a) groups mentioned two standard deviations more pieces of common information than unique information; (b) hidden profile groups were eight times less likely to find the solution than were groups having full information; (c) two measures of information pooling, including the percentage of unique information mentioned out of total available information (the information coverage measure) and the percentage of unique information out of total discussion (the discussion focus measure), were positively related to decision quality, but the effect of information coverage was stronger than that of discussion focus; and communication medium did not affect (d) unique information pooling or (e) group decision quality. Group size, total information load, the proportion of unique information, task demonstrability, and hidden profile strength were found to moderate these effects. Results are discussed in terms of how they offer conceptual advancement for future hidden profile research.
