Shrinking the Size of the Tobacco Power Wall

Primary outcomes

1. Proportion at Risk for Cigarette Smoking

   Time frame: within 5 minutes of the intervention

   A two item self-report assessment: 1) If one of your best friends offered you an unflavored cigarette would you use it? 2) If one of your best friends offered you a menthol cigarette would you use it? Responses to each item are made on a 10-point scale where 1 = definitely not; and 10 = definitely yes and responses across the two items are summed for a total scale score. Total scale scores are dichotomized: scores of 2 are coded as '0' (no risk) and any score greater than 2 is coded as '1' (at risk). Outcome is proportion at risk of cigarette smoking (number of participants at risk over number of participants within condition).

2. Proportion at Risk of Using Electronic Nicotine Delivery Devices (ENDS)

   Time frame: within 5 minutes of the intervention

   A three item, self-report assessment: 1) If one of your best friends offered you an unflavored vaping product would you use it? 2) If one of your best friends offered you a vaping product flavored with menthol or mint, would you use it? 3) If one of your best friends offered you a vaping product flavored with fruit, candy, alcohol or non-alcohol drink, or some other sweet flavor, would you use it? Responses to each item are made on a 10-point scale where 1 = definitely not; and 10 = definitely yes and responses across the three items are summed for a total scale score. Total scale scores are dichotomized: scores of 3 are coded as '0' (no risk) and any score greater than 3 is coded as '1' (at risk). Outcome is proportion at risk of ENDS use (number of participants at risk over number of participants within condition).

3. Proportion at Risk of Using Smokeless Tobacco

   Time frame: within 5 minutes of the intervention

   A three item self report assessment: : 1) If one of your best friends offered you unflavored smokeless tobacco would you use it? 2) If one of your best friends offered you smokeless tobacco flavored with flavored with menthol, mint, spearmint, or wintergreen would you use it? 3) If one of your best friends offered you smokeless tobacco flavored with fruit would you use it? Responses to each item are made on a 10-point scale where 1 = definitely not; and 10 = definitely yes and responses across the three items are summed for a total scale score. Total scale scores are dichotomized: scores of 3 are coded as '0' (no risk) and any score greater than 3 is coded as '1' (at risk).Outcome is proportion at risk of smokeless tobacco use (number of participants at risk over number of participants within condition).

4. Proportion at Risk of Using Little Cigar/Cigarillos (LCC)

   Time frame: within 5 minutes of the intervention

   A three item, self report assessment: 1) If one of your best friends offered you an unflavored cigarillos/filtered cigar would you use it? 2) If one of your best friends offered you a cigarillos/filtered cigar flavored with menthol or mint would you use it? 3) If one of your best friends offered you a cigarillos/filtered cigar flavored with fruit, candy, alcohol, or some other sweet flavor, would you use it? Responses to each item are made on a 10-point scale where 1 = definitely not; and 10 = definitely yes and responses across the three items are summed for a total scale score. Total scale scores are dichotomized: scores of 3 are coded as '0' (no risk) and any score greater than 3 is coded as '1' (at risk). Outcome is proportion at risk of LCC use (number of participants at risk over number of participants within condition).
