Trial Outcomes & Findings for Impact of Vaping Prevention Advertisements (NCT NCT04836455)
NCT ID: NCT04836455
Last Updated: 2024-04-24
Results Overview
The 3-item Susceptibility to Vaping Scale assesses the extent to which adolescents are open to vaping, using a 1 to 4 response option scale. Here, 1 indicates the lowest susceptibility to vaping, and 4 represents the highest, with higher values indicating a greater susceptibility to vaping - essentially, a worse outcome. The overall scale score is determined by averaging the scores of the three items, summing these scores and dividing by 3. This method results in a score range from a minimum of 1 to a maximum of 4.

Timeframe: Week 3Participants will be asked to report the number of days they vaped over the past 21 days. We chose to retain the continuous measure of the number of days spent vaping rather than dichotomizing this outcome, due to the substantial variability observed in the number of days e-cigarettes were used. A higher value indicates more days that participants vaped, which is considered a less desirable outcome (i.e., worse outcome).

SECONDARY outcome
Timeframe: Week 3Participants will be asked to report the number of days they smoked cigarettes over the past 21 days. We chose to retain the continuous measure of the number of days smoking rather than dichotomizing this outcome, due to the substantial variability observed in the number of days cigarettes were used. A higher value indicates more days that participants smoked cigarettes, which is considered a less desirable outcome (i.e., worse outcome).
