Brief Summary

Project RESIST is an R01 study funded by NCI focused on determining the effects of using culturally tailored inoculation approaches to increase resilience to tobacco marketing influences among young adult sexual minority women ages 18-30 and incorporates critical stakeholder inputs that support later adoption and implementation. The study team is utilizing formative research to design and pre-test anti-smoking messages and two national longitudinal online survey experiments.

Outcome Measures

Primary Outcomes (2)

  • Intention to Quit Smoking

    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.

    Day 30

  • Change in Intention to Purchase Cigarettes

    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.

Other: Culturally tailored anti-smoking messages

Non-culturally tailored (Non-smokers)

ACTIVE COMPARATOR

The anti-smoking and anti-industry messages will not be culturally tailored. They will receive only messages that are not culturally tailored at baseline and weeks 1, 2 and 3. Non-culturally tailored interventions: Anti-smoking messages that are not culturally tailored for sexual minority women.

Other: Non-culturally tailored interventions

Culturally Tailored (Smokers)
