Enhancing Trust in Science: Current Challenges and Recommendations for Policymakers, the Scientific Community, Media, and Public
Public trust in science has declined in the US since early 2025. In June 2025, only 8% of U.S. adults reported a great trust in science, a significant drop of nearly 24 percentage points from the previous record of 32% in June 2023. Additionally, in a recent survey by Nature, over 94% of U.S.‐based researchers expressed concerns about the future of science. The scientific community is concerned that current science policies may negatively affect …
Ending the HIV Epidemic: Development and Evaluation of CyberGIS-HIV, a Web-Based Prediction Application
Officials from US state and county health departments perceive the need to adopt new methods for making epidemiological decisions about HIV. Hence, a web-based prediction modeling application, CyberGIS-HIV, was developed and systematically compared with currently used approaches (e.g., community consultation) in a sample of 42 state and federal public health officials as well as senior and junior modelers. Overall, CyberGIS-HIV had more favorable…

Health-promotion interventions targeting multiple behaviors: A meta-analytic review of general and behavior-specific processes of change
186,729 participants) examined the association between the number of behavioral recommendations in multiple-behavior interventions and behavioral and clinical change across eight domains (i.e., diet, smoking, exercise, HIV [Human Immunodeficiency Virus] prevention, HIV testing, HIV treatment, alcohol use, and substance use). Results showed a positive, linear effect of the number of behavioral recommendations associated with behavioral and clinica…

State health policies and interest in PrEP: Evidence from Google Trends
This study investigated the association between interest in Pre-exposure Prophylaxis (PrEP) in the US using Google Health Trends as a source of big data and state policy variables of Medicaid expansions under the Affordable Care Act (ACA) and initiation of PrEP Assistance Programs (PrEP-AP). As of December 2019, thirty-three states and the District of Columbia have accepted federal Medicaid funding provided through the ACA to expand eligibility t…
Testing a digitally distributed method to recruit a network of community organizations to fight the consequences of the drug epidemic: A study in 13 American states
To mitigate the opioid epidemic, a concerted effort to educate, prevent, diagnose, treat, and engage residents is required. In this study, a digitally distributed method to form a large network of organizations was tested with 99 counties in regions with high vulnerability to hepatitis C virus (HCV). The method involved a cascade of contacts going from email to phone calls, to videoconferencing and measuring the number of contacts required, amoun…
Religious affiliation and philosophical and moral beliefs about vaccines: A longitudinal study
How do religious affiliation and beliefs shape vaccine attitudes and behaviors? This study examined the associations of attitudes and behaviors relevant to the flu, measles-mumps-rubella (MMR), and human-papillomavirus (HPV) vaccines with religious affiliations, as well as philosophical, spiritual, and moral beliefs. Respondents were 3005 adults from a probability-based, four-wave panel survey in the United States. Longitudinal structural equatio…
Creating Conspiracy Beliefs: How Our Thoughts Are Shaped
Conspiracy theories spread more widely and faster than ever before. Fear and uncertainty prompt people to believe false narratives of danger and hidden plots, but are not sufficient without considering the role and ideological bias of the media. This timely book focuses on making sense of how and why some people respond to their fear of a threat by creating or believing conspiracy stories. It integrates insights from psychology, political science…

Legacy and social media respectively influence risk perceptions and protective behaviors during emerging health threats: A multi-wave analysis of communications on Zika virus cases
Countering False Beliefs
Although false beliefs about science are at the core of theory and practice in the field of scientific communication, correction and retraction of misinformation entail a complex and difficult process. This chapter first provides a review of trends in scientific retraction and correction notes failures in the fundamental communicative function of signaling that a published finding has been invalidated. It describes the recent practical communicat…
Debunking: A Meta-Analysis of the Psychological Efficacy of Messages Countering Misinformation
This meta-analysis investigated the factors underlying effective messages to counter attitudes and beliefs based on misinformation. Because misinformation can lead to poor decisions about consequential matters and is persistent and difficult to correct, debunking it is an important scientific and public-policy goal. This meta-analysis ( k = 52, N = 6,878) revealed large effects for presenting misinformation ( ds = 2.41–3.08), debunking ( ds = 1.1…
Coping flexibility and psychological adjustment to stressful life changes: A meta-analytic review
Compared with the large body of literature on coping, coping flexibility has received relatively scant research attention, although more such studies have begun to emerge recently. Researchers have conceptualized coping flexibility in diverse ways: as a broad coping repertoire, a well-balanced coping profile, cross-situational variability in strategy deployment, a good strategy-situation fit, or the perceived ability to cope with environmental ch…
