Interventions

Usual Carebehavioral

Participants will receive in-person group counseling from a trained smoking cessation counselor. Participants will learn about reasons to quit smoking, strategies for quitting smoking, and additional resources available to support the quit attempt. Participants will also complete a quit plan.

Depositsbehavioral

Participants will have to deposit a certain amount of their own money at enrollment. Participants will be able to make additional voluntary deposits above the minimum amount during the intervention period. The participant will be refunded all deposits if he quits smoking at 3 months, as verified by a urine cotinine test. The participant will forfeit all deposits if he continues to smoke at 3 months, as verified by a urine cotinine test.

Small Individual Bonusbehavioral

Each participant will receive a monetary bonus from the study investigators if he or she quit smoking, as verified by a urine cotinine test.

Large Individual Bonusbehavioral

Each participant will receive a monetary bonus from the study investigators if he or she quit smoking, as verified by a urine cotinine test. The bonus is twice the value of that in the Small Individual Bonus group.

Teammatebehavioral

Each participant will be randomly assigned one teammate to provide social support during the quit attempt. Each participant will be assigned to a participating coworker who speaks the same primary language and works the same work shift as the participant.

Team Bonusbehavioral

If the participant and assigned teammate both quit smoking at 3 months, as verified by a urine cotinine test, then each will receive a monetary bonus. The team bonus is equal in value to that in the Large Individual Bonus group.
