What this trial studies
This interventional study compares supportive text-message coaching combined with contingent financial incentives to a text-message only program for pregnant women who smoke daily. Eligible participants are adults (18+) enrolled in or applying for WIC or Medicaid, under 30 weeks' gestation, English-speaking, and able to receive texts on a mobile phone. The primary aims are to determine preliminary feasibility and acceptability of the combined approach and to verify smoking abstinence with methods designed to reduce in-person visits. The long-term goal is to create a scalable, low-burden intervention to reduce tobacco use and improve maternal and birth outcomes among low-income pregnant women.
Who should consider this trial
Good fit: Pregnant women aged 18 or older who smoke daily, are enrolled in or applying to WIC or Medicaid, are under 30 weeks' gestation, can read English, and have a mobile phone that receives texts are ideal candidates.
Not a fit: Women who are not at all interested in quitting, who smoked fewer than 24 days in the past month, who are beyond 30 weeks' gestation, who cannot read English, or who lack a mobile phone are unlikely to benefit from this intervention.
Why it matters
Potential benefit: If successful, the program could increase quit rates among low-income pregnant smokers and reduce harm to both mothers and infants using a scalable, low-cost approach.
How similar studies have performed: Prior randomized trials of financial incentives for smoking cessation in pregnancy have produced large effects, but most required in-person verification and combining incentives with text-message delivery is less tested.
