Background. Health-related information found on the Internet is increasing and impacts patient decision making, e.g. regarding vaccination decisions. In addition to statistical information (e.g. incidence rates of vaccine adverse events), narrative information is also widely available such as postings on online bulletin boards. Previous research has shown that narrative information can impact treatment decisions, even when statistical information is presented concurrently. Objectives. As the determinants of this effect are largely unknown, we will vary features of the narratives to identify mechanisms through which narratives impact risk judgments. Methods. An online bulletin board setting provided participants with statistical information and authentic narratives about the occurrence and nonoccurrence of adverse events. Experiment 1 followed a single factorial design with 1, 2, or 4 narratives out of 10 reporting adverse events. Experiment 2 implemented a 2 (statistical risk 20% vs. 40%) × 2 (2/10 vs. 4/...

Abstract 2009 H1N1 influenza A (“swine flu”) vaccine has been offered to healthy UK children aged 6 months–5 years since December 2009, though around 50% of parents plan to reject the vaccine. This study examined whether such parents exhibit omission bias (preference for errors arising from inaction over errors arising from action). One-hundred and forty-two parents completed an online questionnaire in which they rated (a) probability of occurrence, (b) symptoms and (c) duration of a hypothetica...

This large-scale Internet-experiment tests whether vaccine-critical pages raise perceptions of the riskiness of vaccinations and alter vaccination intentions. We manipulated the information environment (vaccine-critical website, control, both) and the focus of search (on vaccination risks, omission risks, no focus). Our analyses reveal that accessing vaccine-critical websites for five to 10 minutes increases the perception of risk of vaccinating and decreases the perception of risk of omitting v...

Eine Online-Recherche zum Thema Impfen macht eine grose Menge impfkritischer Informationen zuganglich. Dabei handelt es sich haufig um personliche Schilderungen von Einzelschicksalen, bei denen nach einer Impfung zeitnah ein negatives Ereignis aufgetreten ist. Die hier vorgestellte Online-Studie zeigt am Beispiel der Masern-Mumps-Roteln (MMR)-Impfung, dass die Bedrohlichkeit, die von solchen Informationen ausgeht, mit der Wahrnehmung der Impfrisiken korreliert. Die resultierende Impfintention ha...

We review the growing literature on health numeracy, the ability to understand and use numerical information, and its relation to cognition, health behaviors, and medical outcomes. Despite the surfeit of health information from commercial and noncommercial sources, national and international surveys show that many people lack basic numerical skills that are essential to maintain their health and make informed medical decisions. Low numeracy distorts perceptions of risks and benefits of screening...

Objective: Icon arrays have been suggested as a potentially promising format for communicating risks to patients—especially those with low numeracy skills—but experimental studies are lacking. This study investigates whether icon arrays increase accuracy of understanding medical risks, and whether they affect perceived seriousness of risks and helpfulness of treatments. Design: Two experiments were conducted on samples of older adults (n 59, 62 to 77 years of age) and university students (n 112,...

Including narratives in health-care interventions is increasingly popular. However, narrative information may bias individual's decision making, resulting in patients making poorer decisions. This systematic review synthesises the evidence about the persuasiveness of narrative information on individuals' decision making. Seventeen studies met the review criteria; 41% of studies employed first person narration, 59% third person. Narrative information influenced decision making more than the provi...

This article reviews a diverse set of proposals for dual processing in higher cognition within largely disconnected literatures in cognitive and social psychology. All these theories have in common the distinction between cognitive processes that are fast, automatic, and unconscious and those that are slow, deliberative, and conscious. A number of authors have recently suggested that there may be two architecturally (and evolutionarily) distinct cognitive systems underlying these dual-process ac...

Narrative is the basic mode of human interaction and a fundamental way of acquiring knowledge. In the rapidly growing field of health communication, narrative approaches are emerging as a promising set of tools for motivating and supporting health-behavior change. This article defines narrative communication and describes the rationale for using it in health-promotion programs, reviews theoretical explanations of narrative effects and research comparing narrative and nonnarrative approaches to p...

Abstract Background News coverage supportive of human papillomavirus (HPV) vaccination is widespread on the Internet. Meanwhile, large numbers of online comments questioning HPV vaccine safety, attacking vaccine manufacturers or providing personal experience of side effects may reduce the persuasion effect. This study explored how and under what conditions such comments influence the behavioral intention of subsequent youth female viewers or readers. Methods We recruited a random sample of 239 C...

People tend to read health articles that have gone viral online. A large portion of online popular vaccine articles are against vaccines, which lead to increased exemption rates and recent outbreaks of vaccine-preventable diseases. Since anti-vaccine articles’ themes and persuasive strategies change fast, their effects on viewers’ behaviors may change over time. This study examined how pro- and anti-vaccine topics and public interests have changed from 2007 to 2017. Computational methods (e.g., ...

Background: Illness narratives with meaningful, competent and targeted content have been shown to provide useful guides for patient decision-making and have positive influences on health behaviors. The use of narratives in decision aids can confer a sense of structure, plot and context to illness experiences and help patients make treatment decisions that feel sensible, informed, and transparent. Aim: This paper presents narratives of suffering and healing from patients and their caregivers with...
