Actual (reported)Perceived Harm
Perceived harm of hookah tobacco is measured using valid self-report item assessing perceptions of how likely harms are to occur from hookah tobacco use (response range 1 no chance to 7 certain to happen). Greater perceived likelihood of harm is considered a better outcome. The assessment is administered immediately post intervention, 3-month follow-up, and 6-month follow-up, 6 month follow-up data reported.
6-months
Perceived Addictiveness
Perceived addictiveness of hookah tobacco is measured using valid self-report item assessing perceptions of how likely one is to become addicted to hookah tobacco (1 = no chance, 7 = certain to happen). Greater perceived likelihood of addictiveness is considered a better outcome. The assessment is administered immediately post-intervention, 3-month follow-up, and 6 month follow-up, 6-month follow-up data reported.
6-months
Worry About Harm
Worry about the harms of hookah tobacco is measured using a valid self-report item assessing how much participants worry about the risks of hookah tobacco (1 = Not at all, 7 = Very much). Greater worry about harm is considered a better outcome. The assessment is administered immediately post-intervention, 3-month follow-up, and 6 month follow-up, 6-month follow-up reported.

Worry About Addictiveness
Worry about the addictiveness of hookah tobacco is measured using a valid self-report item assessing how much participants worry about becoming addicted to hookah tobacco (1 = Not at all, 7 = very much). Greater perceived addictiveness is considered a better outcome. The assessment is administered immediately post-intervention, 3 month follow-up, and 6 month-follow-up, 6 month follow-up reported.
6 months
Motivation to Quit
Motivation to quit is measured using a valid self-report item assessing how much participants want to quit smoking hookah tobacco right now (1 = Not at all, 7 = Very). Greater motivation to quit is considered a better outcome. The assessment is administered immediately post-intervention, 3 month follow-up, and 6 month follow-up, 6-month follow-up reported.
6-months
Hookah Tobacco Use Frequency
Hookah tobacco use frequency is measured using a valid self-report item assessing how often participants have smoked hookah tobacco in the past 30 days. The item measures the number of days in the past month participants have smoked hookah tobacco. Less frequent hookah tobacco use is considered a better outcome. The assessment is administered immediately post-intervention, 3 month follow-up, and 6 month follow-up, 6-month follow-up reported.
6 months
Percent of Participants Who Quit Smoking Hookah Tobacco
Hookah tobacco cessation is measured using a single valid self-report item assessing if participants have stopped smoking hookah tobacco completely. The item asks if participants have completely stopped smoking hookah tobacco based on a yes/no response. Quitting hookah tobacco use (i.e., responses of "yes") is considered a better outcome. The assessment is administered immediately post intervention, 3 month follow-up, and 6 month follow-up, 6-month follow-up data reported.
