Summary
Brief summary (as posted)
Despite a push for tailored messages, health communications are often aimed at, and viewed by, people with varying levels of risk. This project examined-in the context of radon risk messages-whether information relevant to high-risk individuals can have an unintended influence on lower-risk individuals. Specifically, the investigators assessed whether information about lung-cancer risk from smoking reduced concerns about lung-cancer risk from radon among nonsmokers. The investigators hypothesized that non-smokers who read a message that included smoking-relevant information would express less concern about the effects of radon exposure and less interest in testing their home compared to those who read a version in which smoking-relevant information was excluded. Two studies were conducted. Although the investigators did not exclude smokers, the focus was on participants self-identifying as nonsmokers (including never smokers and former smokers).
