Assessment of intentions to use the viewed smokeless tobacco products based on averaging responses to three parallel questions: "Thinking about the ads you saw for \[General Snus or Copenhagen\] products, how interested, in the next 6 months, would you be in: 1) Using or trying these products? 2) Using these products as a way to quit or cut down on your cigarette smoking? 3) Completely switching from cigarettes to these products? Response options to each were on a 5 point scale from (1=not at all interested to 5=extremely interested). Results presented here are based on the averaged responses to these three items. Higher scores mean greater interest in using the products.

时间窗: Assessed in survey measures completed immediately after viewing the study stimuli

Assessment of perceived risks of getting various smoking related diseases from using the viewed smokeless tobacco product versus from smoking cigarettes. Responses to 6 parallel questions (each asking about a different disease) were averaged together in this composite item. The question stated: "If you used only \[General Snus/Copenhagen - inserted based on brand condition\] or only cigarettes every day, which product would make it more likely that you would get": 1) lung cancer; 2) heart disease; 3) mouth cancer; 4) stroke; 5) chronic bronchitis; 6) emphysema. Response options to each were on a 5 point scale from (1=much more likely with General Snus/Copenhagen to 5=much more likely with cigarettes). Results presented here are based on the averages responses to the six items. Higher scores mean thinking risks are greater from smoking cigarettes than from using the viewed smokeless tobacco product.
