Dark Patterns in Data-Consent Disclosures and Consumer Reactance to Online Behavioral Advertising
This research investigates how dark patterns in data consent disclosures influence consumer responses to online behavioral advertising (OBA). Integrating the persuasion knowledge model (PKM), psychological reactance theory (PRT), and a cognitive accessibility perspective, we propose a framework explaining how manipulative consent designs shape perceptions of privacy threat, control, and persuasion outcomes. Across three studies, we demonstrate th…
The Role of Optimistic Bias and Affect on Social Media Searches About Covid-19
The preventive health behavior people adopt is partly a result of the risk they perceive from the threat, and health behavior theory has shown that risk communication is a critical part of that outcome. But risk to self and risk to others are often judged differently. Optimistic bias, which describes an unrealistic level of optimism about a threat, is a well described and frequently observed phenomenon in the study of health behavior. Traditional…
Exploring the Cognitive, Affective, and Conative Factors of Bystander Intervention to Improve Protective Measures During Health Emergencies
This study examines the factors shaping individuals' reactions to health-protective norm violations through the lens of cognitive accessibility, the risk-as-feelings hypothesis, and the tripartite decision-making framework. By surveying 1,426 U.S. college students, we found that frequent exposure to health information in the media is associated with an increased tendency to adopt health-protective measures and support bystander intervention (upst…
Exploring public-sector YouTube influencer PR strategies
This study employs a mixed-methods approach to analyze YouTube influencer strategies in public-sector communication, focusing on South Korea’s most-subscribed local government channel. Phase I employs an inductive approach based on in-depth interviews with the channel’s creator. This phase develops a grounded model of effective public relations (PR) strategies, highlighting crucial organizational factors, content themes, and creator attributes. P…
Standing Up to the Maskless
Extending theorization on bystander intervention, this study examined antecedents of upstanding, a communication practice in which bystanders communicate disapproval to norm violators, using the context of mask wearing during COVID-19. Survey findings from undergraduate students revealed that perceived legitimacy of intervention played a key role in decisions to stand up to mask norm violators. In addition, anticipation of hostile responses from …
Interpersonal Communication Influence on Health-Protective Behaviors amid the Covid-19 Crisis
Harnessing an Integrated Health Communication (IHC) Framework for Campaigns
Drawing on a multiplicity of mass media and health behavior theories, we propose an integrated health communication (IHC) framework to understand and leverage the ways in which mass mediated and interpersonal sources of health information influence the public's health behavior in the context of their prescription drug decisions. Building on the agenda setting theory, two-step flow theory, and the Health Belief Model, we dig into the interrelation…
Optimistic Bias and Consumer Prescription Drug Decisions
This study examines how optimistic bias moderates the association of direct-to-consumer prescription drug advertising (DTCA) exposure with consumers' responses to DTCA. We propose and test a model that addresses how exposure to DTCA plays a role in health risk assessment and prescription drug decision engagement. Findings from an online survey of U.S. adults (n = 628) demonstrated that exposure to DTCA is positively associated with consumers' per…
