Project RESIST: Increasing Resistance to Tobacco Marketing Among Young Adult Sexual Minority Women Using Inoculation Message Approaches

Primary outcomes

1. Intention to Quit Smoking

   Time frame: Day 30

   Intention to quit smoking will be measured using the Burkhalter intention to quit smoking four item scale that measures readiness to cut down or quit smoking in the next 30 days at baseline and 1 month follow-up.

   Participants were asked to rate 4 statements: I will make an effort to quit smoking in the next 30 days (Unlikely to Likely); I intend to quit smoking in the next 30 days (Strongly disagree to Strongly Agree); I expect to quit smoking in the next 30 days (Definitely false to Definitely true); How likely is it that you will quit smoking in the next 30 days (Unlikely to Likely). Responses ranged on 7-point Likert-like scales. Responses were summed to create a scale for intention to quit (range from 4-28).

   This will only be measured among current smokers. Lowest score is 4 and highest mean score is 28. Higher scores indicate increased intention to quit smoking within the next 30 days.

2. Change in Intention to Purchase Cigarettes

   Time frame: Day 30

   The Juster scale was used to measure intention to purchase cigarettes at baseline and at one-month follow-up.

   Participants were asked, "How likely are you to purchase cigarettes in the next 6 months?" Responses ranged from 0=No chance, almost no chance (1 in 100) to 10=Certain, practically certain (99 in 100).

   Higher values reflect higher intention to purchase.
