Detailed Summary

This project will use the Multiphase Optimization Strategy (MOST) to guide the development of optimized treatment strategies for the two most effective smoking cessation medications (Combination Nicotine Replacement \[C-NRT\] and varenicline). The investigators will recruit daily smokers from primary care to participate in a fully crossed, 2x2x2x2 factorial experiment (N=608) that evaluates 4 different factors: 1) Medication Type (Varenicline vs. C-NRT), 2) Preparation Medication (4 Weeks vs. Standard), 3) Medication Duration (Extended \[24 weeks\] vs. Standard \[12 weeks\]); and 4) Counseling (Intensive vs. Minimal). Participants will complete assessments one week pre-quit and then assessments of smoking status, treatment use, side effects, potential treatment mechanisms (e.g., withdrawal, self-efficacy) during the first week post-target quit date (TQD) and at Weeks 2, 4, 12, 20, 26, and 52 post-target quit date. These data will be used to examine the main and interactive effects of these four factors on various outcomes, with biochemically confirmed 12-month abstinence serving as the primary outcome. These data will also be used to determine which factors and combinations of factors are most effective with regard to 12-month biochemically confirmed abstinence and cost, thereby identifying optimized varenicline and C-NRT treatments, with each developed to yield especially great benefit. These optimized treatments will then be tested in the Optimized Care Project. The investigators will also examine the relative effects of each medication on particular outcomes (e.g., 12-month abstinence).

Arms & Interventions

12-week Varenicline with Minimal Counselingactive_comparator

Participants randomized to this intervention will receive one 0.5 mg pill for the first 3 days, starting 1 week prior to the target quit day (TQD). They will then use one 0.5 mg pill twice daily for the next 4 days. After the first week of study medication ramp up, participants will use one 1 mg pill twice daily until 11 weeks post-TQD. Participants randomized to this intervention will receive a brief (15-30 minute) phone or video counseling session 1 week prior to the TQD to promote engagement with free mobile health resources and then a brief (10-20 minute) follow-up phone or video session during the first week post-TQD to mimic a nurse or clinician follow-up after a quit attempt.
