Text Messages + Incentives for Smoking Cessation in Pregnant Women

This study is looking at how well a program combining text messages and financial rewards helps pregnant women stop smoking. It's designed for women who are currently smoking, are at least 18 years old, and are enrolled in WIC or Medicaid. The program uses "SmokeFreeTXT" messages with specific content for pregnant women, and offers daily incentives (rewards) for staying smoke-free, verified by breath tests. Researchers want to see if this approach is practical and acceptable, and how effective it is at helping women quit smoking by 12 weeks after starting the program. The study aims to enroll 50 participants, but its current status is unclear.

Study design
This is an interventional study with an unclear phase, planning to enroll 50 participants. It compares a group receiving text messages plus incentives to a group receiving only text messages.
What's involved
Participants will receive scheduled text messages and, in one group, will need to complete twice-daily CO (carbon monoxide) assessments for several weeks, sending verification via text message.
Compensation
Participants in the intervention group will receive daily incentives for each day of smoking abstinence.
Follow-up
The study measures outcomes like smoking abstinence and intervention acceptability at 12 weeks post-randomization.
