Smartphone-based Incentives Intervention to Increase Smoking Cessation During Pregnancy

20. September 2026 aktualisiert von: Stephen T. Higgins, PhD, University of Vermont

Examining a Digital Perinatal Smoking-Cessation Intervention

Cigarette smoking is the leading preventable cause of poor pregnancy outcomes in the U.S. and a problem for which more effective and easy-to-access treatments are much needed. This study examines whether outcomes achieved with recommended clinical practices (referral to state tobacco Quitline with follow-up and further referrals for those continuing to smoke) can be improved by also offering financial incentives delivered through a smartphone for maternal smoking abstinence.

Detaillierte Beschreibung

Pregnant women residing in the U.S. who currently smoke cigarettes and are interested in quitting will be recruited nationally and randomly assigned to what is considered clinical best practices (BP) (referral to state tobacco Quitline with follow-up and further referrals for those continuing to smoke) or best practices in combination with financial incentives (BP+FI). Women assigned to the BP+FI treatment will have opportunities to earn financial incentives by abstaining from smoking during pregnancy and for 3 months after delivering their baby (total possible incentives is $750.00). Women will demonstrate that they have abstained by taking brief salivary cotinine tests using a smartphone or equivalent device. Incentives for abstaining are electronically added to a study-provided debit card. Participation and all results are strictly confidential. Participants in both treatment conditions will be financially compensated for study participation with potential earnings of $525.00. Total potential earnings for those assigned to BP is $525.00 and for those assigned to BP+FI it is $1,275 ($525 for study participation and $750 in incentives for quitting smoking).

Experimental: Best Practices

Best Practices (BP) entails the 5As including referral to the state tobacco Quitline and further referral for those continuing to smoke.

Participants receive the 5As including a staff referral to the state tobacco quitline.

Experimental: Best Practices plus Financial Incentives

Best practices plus providing financial incentives contingent on biochemically verified abstinence. Incentives are in the form of vouchers exchangeable for retail items and available through 12-weeks postpartum.

Ergebnis Maßnahme
Maßnahmenbeschreibung
Zeitfenster
Antepartum smoking abstinence
Zeitfenster: Antepartum period is from study entry through infant delivery which is typically about 24 weeks duration.

The primary outcome is whether women randomly assigned to the two treatment groups differ in the percentage who abstain from smoking across an early (< 25 weeks gestation) and late (> 25 weeks gestation) antepartum assessments defined by the percentage of participants assigned to each condition who report no smoking in the past 7 days and submit of a salivary cotinine sample that tests negative for recent smoking.

Antepartum period is from study entry through infant delivery which is typically about 24 weeks duration.

Zeitfenster
Postpartum smoking abstinence
Zeitfenster: 2-weeks, 6-weeks, 12-weeks following delivery.

Smoking abstinence at 2, 6, and 12 weeks postpartum defined as the percent of participants randomly assigned to each of the two treatment conditions who report no smoking in the past 7 days and submit of a salivary cotinine test sample that is negative for recent smoking.

Birth Outcomes
Zeitfenster: Birth record at time of delivery

Birth outcomes calculated from data extracted from the birth delivery reports include mean birth weight, % low birth weight deliveries (< 2500 g), mean gestational age at delivery, % premature deliveries (< 37 weeks), incidence of Neonatal Intensive Care Unit (NICU) admissions, and mean length of stay per NICU admission.

Birth record at time of delivery
Treatment Acceptability Questionnaire
Zeitfenster: 24 weeks following delivery

Participants in both treatment conditions will complete the Treatment Acceptance Questionnaire (TAQ) at the 24-weeks postpartum assessment. The TAQ will query participants about the (1) ease of use of their assigned intervention; (2) helpfulness, and (3) convenience of the intervention; (4) whether the intervention facilitated engagement with smoking-cessation treatment; (5) whether the intervention was fair, (6) fun, (7) or helpful in abstaining from smoking during pregnancy, (8) after the baby was born, and (9) longer-term; and (10) whether they would recommend the treatment that they received to others. All responses will be made using a 100-point visual analogue scale with higher scores represent greater acceptance.

24 weeks following delivery
Smoking abstinence at 24-weeks postpartum
Zeitfenster: 24 weeks after delivery

Participants report no smoking in the past 7 days that is confirmed with a negative salivary cotinine test

Cost effectiveness
Zeitfenster: 24-weeks postpartum

A cost-effectiveness analysis of adding financial incentives to the Best-Practices intervention will be conducted.

Upon study completion and publication of the primary trial outcomes in a peer-reviewed journal and planned secondary outcomes (e.g., birth outcomes, cost-effectiveness). Anticipated start date is 3 years after trial completion. Anticipated end date is 5 years after study completion.

IPD-Sharing-Zugriffskriterien

Briefly, this trial will use the standard processing and documentation protocols adopted by the Inter-university Consortium for Political and Social Research (ICPSR). All shared data, metadata, and associated documentation will be deposited via the National Addiction & HIV Data Archive Program (NAHDAP), which is hosted by ICPSR. The scientific data provided by our trial will be findable via a study digital object identifier (DOI) minted by ICPSR. Users of our shared scientific data must register with ICPSR and agree to the Terms of Use, which allows use only for scientific research purposes and aggregate statistical analyses.
