About this study

The long-term goal of this research is to reduce tobacco-related disparities in maternal and infant health outcomes by improving smoking cessation and relapse prevention interventions for minority pregnant and postpartum women, who have been significantly underrepresented in smoking cessation research. This study will examine the feasibility and efficacy of a prize-based contingency management approach for increasing smoking cessation and preventing relapse among socioeconomically disadvantaged minority pregnant smokers. First, the intervention will be pretested with 10 pregnant low-income minority smokers and then refined based on acceptability survey and focus group data. Next, a pilot study will be conducted. 60 highly disadvantaged minority women, recruited from the outpatient obstetric clinics at a large teaching hospital, who report daily smoking and who meet other eligibility criteria will be enrolled and randomized to one of two study conditions: 1) Standard Psychoeducational Intervention (6-week, individually-administered, pregnancy-specific Quit Smoking Now curriculum, as currently implemented in the clinic; QSN Only); 2) Standard Psychoeducational Intervention plus Contingency Management (provision of incentives contingent on biochemically-verified abstinence; QSN-CM). Abstinence monitoring via expired carbon monoxide and salivary cotinine levels will occur in both groups beginning on the first quit day and continuing through 3-months postpartum. Only participants in the QSN-CM group will be reinforced for biochemically-verified abstinence with chances to win prizes ranging in value from approximately $1 to $100 ('fishbowl' or 'prize bowl' method). Study outcomes will be assessed through follow-up research exams (delivery and 6-months postpartum) and hospital chart reviews. The primary hypothesis is that that women randomized to the QSN-CM condition will have higher rates of abstinence during pregnancy and postpartum compared to women receiving standard of care alone. Results should advance scientific knowledge regarding effective methods for promoting and maintaining smoking abstinence among pregnant disadvantaged women and provide preliminary feasibility and efficacy data needed to support a larger randomized controlled trial.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Quit Smoking Now (QSN)Other

    The Quit Smoking Now (QSN) program, offered by the Florida Area Health Education Center, was developed based on principles of the Centers for Disease Control and Prevention's "Best Practices for Comprehensive Tobacco Control", and the U.S. Department of Health and Human Services' "Treating Tobacco Use and Dependence Clinical Guidelines" with an emphasis on reaching medically-underserved populations. The QSN curriculum will be delivered in 6 one-hour sessions . Pregnancy-specific session goals and content cover the effects of smoking on the developing fetus, secondhand smoke exposure, the importance of social support, and postpartum relapse.

  • Prize-based Contingency Management (CM)Behavioural

    Women will earn chances to win prizes for biochemically verified abstinence from tobacco.

QSN with CM (QSN-CM).ExperimentalWomen will receive standard of care Quit Smoking Now tobacco education and support plus prize-based contingency management. Their smoking status will be monitored from quit date through 3 months postpartum via carbon monoxide and salivary cotinine levels. Women will earn chances to win prizes each time they test negative for smoking according to biochemical measures.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Abstinence Duration

    -duration in days

    --measured by self-report, carbon monoxide, salivary and urine cotinine levels

    Measured: (from quit date through 6 months postpartum; assessed up to 52 weeks)

  2. Abstinence rate (%)

    • 7-day point prevalence abstinence at delivery and 6 months postpartum defined by no smoking in the 7 days prior to assessment.
    • measured by self-report, carbon monoxide and salivary cotinine levels.

    Measured: delivery and 6 months postpartum

  3. QSN attendance

    • cumulative attendance at QSN sessions (1-6 weeks)
    • QSN attendance logs

    Measured: (6 weeks)

Secondary outcomes (5)
  1. Smoking reduction

    -change in the number of cigarettes smoked daily by self-report

    Measured: Change (baseline and delivery; baseline and 6 months postpartum)

  2. Gestational Age

    • measured in weeks
    • documented through medical chart review

    Measured: delivery

  3. Infant Respiratory Illnesses

    • number of episodes
    • documented through medical chart review

    Measured: 6 months postpartum

  4. Birth Weight

    • birth weight measured in grams
    • documented through medical chart review

    Measured: delivery

  5. Neonatal Admissions

    • duration in days
    • documented through medical chart review

    Measured: delivery

Questions about this trial

What is this clinical trial studying?

A study testing Quit Smoking Now (QSN) and Prize-based Contingency Management (CM) in people with Cigarette Smoking, run by University of Miami at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 9 May 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Abstinence Duration (time frame: (from quit date through 6 months postpartum; assessed up to 52 weeks)). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 May 2019.
