---|---|
Experimental: Multicomponent behavioral intervention
The multicomponent intervention group will receive education and counseling, monitoring and feedback, contingent financial incentives, and family support.
|
Behavioral: Multicomponent behavioral intervention
Pregnant patients in the intervention group will receive multicomponent interventions consisting of education, feedback, contingent financial incentives, and peer support. At initial intervention visit, they will choose a quit date within the next 14 days and sign a no-smoking pledge and a no-smoking contract. The contract lists the intervention components, the patient's and the counselor's responsibilities, importance of keeping scheduled visits, and rules on contingent incentives. After the quit date, pregnant women will meet with counselors daily for 5 consecutive days (Monday to Friday) for abstinence monitoring in weeks 1-2. The frequency of abstinence monitoring will decrease to twice a week (Monday and Thursday) in weeks 3-8, weekly in weeks 9-12, and biweekly in weeks 13 until delivery. |
Active Comparator: Control
The control group will receive smoking cessation education only.
|
Behavioral: Education only control
The control group will receive one 60-minute counseling mainly based on a pregnancy-tailored self-help booklet entitled "Need Help Putting Out That Cigarette?" distributed by the American College of Obstetricians and Gynecologists. |
