Aim 1: Compare the efficacy of an In Vivo experiential intervention to a standard treatment control group for smoking cessation. The goal of this aim will be to compare the rates of point prevalence abstinence at the 6 month post-intervention follow-up. It is expected that smokers who receive the behavioral experience of the NRT In Vivo intervention will have higher rates of abstinence at the 6 month follow-up compared to the control group. Aim 2: Compare medication adherence between groups over the 12 week intervention. The goal of this aim is to determine the impact of the In Vivo behavioral experience intervention on promoting medication adherence to NRT. It is expected that individuals in the In Vivo NRT group will have better medication adherence relative to control participants. Exploratory: Examine moderators and mediators of the experimental intervention on smoking abstinence. The goal of this aim is to explore whether demographic and smoking characteristics (e.g., sex, race, nicotine dependence, motivational status, legal charges) moderate the effect of treatment on abstinence after 12 weeks of treatment and 6-month follow-up. In addition, we will look at changes in expectancies about NRT, medication adherence, and withdrawal symptoms to determine if these changes mediate the relationship between the experimental intervention and smoking abstinence.
