Brief Summary

The current study aimed to test a culturally tailored program designed to help Pacific Islanders (PIs) between the ages of 18 and 30 quit smoking cigarettes by using a randomized controlled trial design with one intervention group and one control group.

Detailed Description

This randomized control trial (RCT) consisted of a baseline assessment (Wave 0) and three follow-up assessments (Waves 1-3). Follow-up assessments were conducted at 2 months, 5 months, and 8 months after the baseline assessment. The objective of the study was to test a culturally-tailored online program designed to help PI young adults quit smoking cigarettes. The online program contained (1) personalized, automated text messages, (2) interactive, online educational modules, and (3) an online forum.

Hypotheses for this study include:

1. Participants in the intervention program tailored to PIs would have significantly higher rates of abstinence, lower rates of relapse, and lower smoking frequency and intensity at each follow-up time point than those in the standard intervention program.

2. Participants with impaired affective decision capacity (low scores on Iowa Gambling Task (IGT)) would benefit more from the tailored intervention program than participants with normal affective decision capacity (high IGT scores).

3. Effects from the tailored intervention program would be more pronounced among participants with particular dispositional phenotypes (depression, hostility, impulsivity) and baseline severity of tobacco addiction (nicotine dependence).

4. High-intensity users of the tailored intervention program would be more successful than low intensity users in reducing the frequency and intensity of cigarettes smoked.

5. The tailored intervention program would have greater success at engaging and retaining participants than the standard intervention program.
