Waffen und Interventionen
Teilnehmergruppe / Arm |
Intervention / Behandlung |
|---|---|
|
Experimental: Text-only PWL, immediate post
Exposure to 4 FDA-mandated warning labels and numeric risk information for 8 outcomes related to those warnings (2 outcomes for each PWL; half as percentage, half as frequency) Posttest measures (e.g., memory, risk perceptions, quit intentions) administered immediately following last exposure to warning labels |
|
|
Experimental: Text-only PWL, delay posttest
Exposure to 4 FDA-mandated warning labels and numeric risk information for 8 outcomes related to those warnings (2 outcomes for each PWL; half as percentage, half as frequency) Posttest measures (e.g., memory, risk perceptions, quit intentions) administered 6 weeks following last exposure to warning labels |
|
|
Experimental: Low-emot PWL, immed post
Exposure to 4 FDA-mandated warning labels paired with images that elicit little emotion and numeric risk information for 8 outcomes related to those warnings (2 outcomes for each PWL; half as percentage, half as frequency) Posttest measures (e.g., memory, risk perceptions, quit intentions) administered immediately following last exposure to warning labels |

Experimental: High-emot PWL, immed posttest
Exposure to 4 FDA-mandated warning labels paired with images that elicit high emotion and numeric risk information for 8 outcomes related to those warnings (2 outcomes for each PWL; half as percentage, half as frequency) Posttest measures (e.g., memory, risk perceptions, quit intentions) administered immediately following last exposure to warning labels |

Was misst die Studie?
Primäre Ergebnismessungen
Ergebnis Maßnahme |
Maßnahmenbeschreibung |
Zeitfenster |
|---|---|---|
|
numeric risk recall
Zeitfenster: immediately following last exposure or after 6-week delay
|
free recall for numeric risks presented in labels (e.g., ____% of smokers die before age 85), both for smokers and nonsmokers
|
immediately following last exposure or after 6-week delay
|
|
numeric risk recognition
Zeitfenster: immediately following last exposure or after 6-week delay
|
Participants answered one multiple choice question about the numeric risk for smokers and nonsmokers (combined in one question) for each of the 8 outcomes that had been paired with the PWLs.
For each question, there were four decoy responses.

Ergebnis Maßnahme |
Maßnahmenbeschreibung |
Zeitfenster |
|---|---|---|
|
smoking risk perceptions
Zeitfenster: immediately following last exposure or after 6-week delay
|
Participants completed several scale items about how much risk they perceived smoking posed to them (e.g., "Compared to the average nonsmoker your age, gender, and race, how would you rate your chances of": 1) "getting a life threatening illness because of smoking," 2) "getting lung cancer," and 3) "dying at a younger age than average" (-3 = Much lower, +3 = Much higher)) They also gave verbal likelihood ratings for each of the 8 outcomes of smoking that had been paired with the labels (e.g., "Thinking of risks that you were shown in the warnings, what is the likelihood of a smoker [non-smoker] dying from heart disease?," 0=impossible, 11=certain) |
immediately following last exposure or after 6-week delay
|
|
smoking risk knowledge
Zeitfenster: immediately following last exposure or after 6-week delay
|
Participants listed as many risks of smoking as they could think of.
|
immediately following last exposure or after 6-week delay
|
|
quit intentions
Zeitfenster: immediately following last exposure or after 6-week delay
|
Participants intentions to quit smoking, Likelihood of smoking within next 30 days, next year (-3 = very unlikely, 3 = very likely)
|
immediately following last exposure or after 6-week delay
