Title: A Computer-Assisted Brief Motivational Intervention for Smoking During Pregnancy: The Healthy Pregnancy Project (HPP)
Brief Summary: This study will develop:

1. Develop the computer-based brief intervention and Contingency Management (CM) components, with repeated feedback from experts, prenatal clinic staff, and participants.
2. Recruit 110 pregnant women who are actively smoking, and randomly assign recruited women to Brief Intervention, CM, combined, or control conditions.
3. Conduct follow-up evaluation at 12 weeks post-intervention to measure self-reported smoking, breath carbon monoxide (CO), and urinary cotinine levels.
4. Collect data regarding birth outcomes and evaluate the feasibility of various methods of post-partum follow-up.
