The main research instruments will consist of questionnaires on a subjects smoking habits and psychological tests that will help evaluate which types of patients are most able to quit smoking. All participants will be asked to complete an intake questionnaire at baseline (estimated length 15 minutes) and an exit questionnaire at the end of study participation 3 months after they start in the program (estimated length 15 minutes). Investigators will examine whether baseline values and/or changes during 3 months in these variables confound, causally mediate, or modify the effects of the intervention on quit rates. (a) Standard questionnaires will be administered to collect the following information: demographics (age, gender, ethnicity, marital status, and education), number of years of smoking, number of prior quit attempts, duration of previous abstinence periods, and current smoking rate. Nicotine dependence will be measured by the modified Fagerström Test for Nicotine Dependence (FTND), a 6-item measure of nicotine dependence. The FTND has satisfactory internal consistency (Cronbachs alpha=0.64) and high test-retest reliability (r=0.88).3 Heavy smokers are at highest risk for smoking related illnesses. Some but not all studies suggest that heavier smokers have lower quit rates. Investigators will evaluate whether FTND score either confounds or modifies the effects of the intervention. (b) Investigators will measure smoker's baseline readiness to quit using the Prochaska Stage of Change. (c) Investigators will assess participant's types and locations of jobs and whether they are exposed to smoking at home or in the workplace. (d) Participants use, durations, and doses of nicotine replacement therapy, varenicline, and buproprion will be assessed throughout the study. Participants will be asked to not use Nicotine patches or gum during the course of the study so that it will not interfere with weekly testing for smoking abstinence. (e) Time (or delay) discounting. Time discounting (known interchangeably as present-biased preferences or delay discounting) is a measure of impulsivity that reflects people's tendencies to discount the value of a reward as a function of how far in the future it would be received. People who smoke and use other drugs have steeper delayed discounting functions, meaning they have stronger present biased preferences. This is expected because smoking, like other unhealthy behaviors, entails immediate gratifications in exchange for future health problems. This also suggests that provision of early rewards, such as payments, might more effectively promote smoking cessation than interventions focusing on future rewards such as long-term health benefits, and that this effect might be strongest among those with the steepest discounting functions. Consistent with prior work, investigators will use a 7-item monetary choice questionnaire that defines ranges of delayed discounting by fitting a hyperbolic function to participants expressed preferences for smaller immediate versus larger delayed rewards. Information will also be collected weekly from participants on withdrawal and craving for nicotine as well as self-reported number of cigarettes per week. Investigators will also administer a 5 question weekly survey that addresses weekly levels of cravings, stress, social support, and asks about current cigarette use. All questions will be rated on a Likert scale, except for the number of cigarettes smoked, that will be an estimate of use.
