Abstract

Patients have ever-increasing access to web-based news about hopeful scientific developments that may or may not cure them in the future. Science communication experts agree that the quality of news provision is not always guaranteed. However, literature does not clarify in what way users are actually affected by typical news characteristics such as the news object (described developmental phase of an innovation), the news source (degree of authority), and the news style (degree of language intensification). An online vignette experiment (N = 259) investigated causal relationships between characteristics of news about diabetes innovations and patients' perceptions of future success, their interest in the innovation, and attitudes regarding current therapy adherence. Findings show that descriptions of success in mice led to higher estimations of future success chances than earlier and later developmental phases. Furthermore, news from a nonauthoritative source led to an increased interest in the innovation, and a more negative attitude towards current lifestyle advice. Lastly, the intensification of the language used in news messages showed slight adverse effects on the readers' attitude. These findings, combined with their small effect sizes, support the optimistic view that diabetes patients are generally critical assessors of health news and that future research on this topic should focus on affected fragile subgroups.
