Fixation time variables were measured in seconds. Negative affect was measured on a scale of 1–5. Old risk beliefs were measured on a scale of 0–4. New risk beliefs were measured on a scale of 0–4 for adults and 0–5 for youth. Values for smoking intentions/susceptibility to smoking are proportions indicating percentage of participants in each condition who reported intention to quit in 7 days, 30 days, or 6 months (adults) or who reported they would try smoking (youth).
