Summary

Using the NIH-funded Way to Health platform, the investigators will conduct this smoking cessation randomized controlled trial (RCT) among CVS employees. The investigators will be able to determine the comparative and absolute efficacy and effectiveness of 4 different incentive structures that are each grounded in behavioral economic principles. Additionally, the investigators will measure rates of and reasons for acceptance of each incentive structure, and examine participant characteristics that modify the efficacy and acceptance of different incentive structures.

Detailed description

Specific Aim I: Compare the efficacy and effectiveness of 4 financial incentive structures for improving "quit rates" (rates of prolonged smoking abstinence for 6 months): (a) individual financial rewards, (b) individual deposit contracts, (c) cooperative rewards, and (d) competitive deposit contracts H1: Compared with usual care, all 4 incentive structures will increase quit rates significantly. H2: Compared with individual financial rewards of equivalent size and schedule, individual deposit contracts, cooperative rewards, and competitive contracts will each increase quit rates significantly. H3: Group-oriented structures will increase quit rates significantly more than individual-oriented structures. Specific Aim II: Compare smokers' acceptance of these 4 financial incentive structures for smoking cessation H4: Uptake rates of reward-based structures will be higher than of structures involving deposit contracts. H5: Uptake rates of group-oriented structures will be higher than of individual-oriented structures. Specific Aim III: Identify individual characteristics that modify incentive structures' efficacy and acceptance H6: Incentives will promote relatively greater quit rates among participants with fewer substitute reinforcers. H7: Incentives will promote relatively greater quit rates among participants with lower incomes. H8: Higher-income persons will be relatively more likely to accept incentives requiring deposit contracts.

Interventions

Type	Name	Description
BEHAVIORAL	Usual Care	Participants will receive reimbursements for completing the surveys that are part of the Way To Quit program and for submitting saliva or urine samples at 14 days, 30 days, 6 months, and 12 months (among those eligible).
BEHAVIORAL	Individual Rewards	If participants quit smoking by their target quit date, and that is confirmed by cotinine/anabasine tests, they will receive a monetary award from the study investigators.
BEHAVIORAL	Fixed Deposits	Participants will have to deposit a certain monetary amount of their own money as an incentive to quit smoking. If they quit smoking by their target quit date, and that is confirmed by cotinine/anabasine tests, participants will receive their deposit back. If participants do not quit, their money will be used to support future research studies designed to help people stop smoking. As a motivation to quit smoking, the participant's deposit will be matched by the study investigators in a rate of 3:1.
BEHAVIORAL	Competitive Deposits (Pari-Mutuel)	Groups (or "cohorts") of 6 smokers each will be formed on a rolling basis, linking individuals with target quit dates (day "0's") near each other. Participants will deposit a certain monetary amount (Y) in an account, which will be matched on a rate of 3:1 by the study investigators (M), and the payout for quitting on this arm will be (Y+M) x 6/Q , where Q is the number of quits in the cohort. Again, success will be confirmed by cotinine or anabasine tests, and if participants do not quit, their money will be used to support future research studies designed to help people stop smoking.
BEHAVIORAL	Collaborative Rewards	Groups (or "cohorts") of 6 smokers each will be formed on a rolling basis, linking individuals with target quit dates (day "0's") near each other. If participants quit smoking by their target quit date, and that is confirmed by cotinine or anabasine tests, they will receive a monetary award from the study investigators. On top of that, participants will receive an additional monetary amount for each member of their group who also quits smoking. These participants will interact through a chat room, which will help motivate them to quit smoking.
