Smoking Cessation for Young Adult Pacific Islanders: Motivating Pacifika Against Cigarettes and Tobacco

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.

About this study

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:

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

Treatment and study plan

Motivating Pacifika Against Cigarettes and Tobacco

Behavioral

Participants received one encouraging text message per day prior to their quit date. During the intervention, they received daily text messages with decreasing frequency per week. Participants were also able to craft personal text messages. On-demand text messages were optional and could be requested by texting key words to the program hotline.

The online MPACT program allowed participants to access eight educational modules and a forum where they could communicate with other participants. The modules focused on different aspects of quitting smoking, such as how to deal with withdrawal symptoms, triggers of tobacco use, and stress. Participants were limited to one module per day in order to increase the duration of exposure to the program. Upon completion, participants no longer received text messages but they were still able to access the educational modules, forum, and on-demand text messages.
