Effective Formats for Communicating Risks from Cigarette Smoke Chemicals
Objective: The US government requires the public display of information about toxic chemicals in cigarettes and smoke by brand in a way that is understandable and not misleading. We sought to identify risk communication formats that meet these goals. Methods: We conducted 3 online experiments with US adult convenience samples (total N = 1866). Participants viewed a webpage displaying information about chemicals in the smoke of a cigarette brand. Experiment 1 varied the chemicals listed and format for their health effects. Experiments 2 and 3 varied the format of chemical quantities and presence/absence of a visual risk indicator. Outcomes were understandable (increasing knowledge) and not misleading (not reinforcing misperceptions). Results: Information about chemicals and health effects increased knowledge of these topics by ~30% (p < .001) compared to no information. Quantity format and use of a risk indicator generally did not affect knowledge. The proportion of participants misled ranged from 0% to 92%, depending on measure. Findings indicated 52% would use a website to search for safer cigarettes. Risk communication formats did little to reduce being misled. Conclusions: Some risk communication formats successfully increased knowledge of chemicals and health effects. However, the formats did little to reduce the proportion of people misled.
