Trial Outcomes & Findings for Shrinking the Size of the Tobacco Power Wall (NCT NCT04632030)
NCT ID: NCT04632030
Last Updated: 2023-10-25
Results Overview
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).

PRIMARY outcome
Timeframe: within 5 minutes of the interventionPopulation: Sample size may differ from baseline because of missing data.
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).

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).

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).

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).
