Trial summary

Incentives can be used to facilitate the acquisition of many healthy behaviors, such as smoking cessation. However, there is much room for improvement in the use of incentives. This study investigates how two aspects of providing incentives influence the effectiveness of using incentives to promote smoking cessation. Read more about this study

About this study

Official title: Increasing Contingency Management Success Using Shaping

Incentives can be used to facilitate the acquisition of many healthy behaviors, such as smoking cessation. However, there is much room for improvement in the use of incentives. This study investigates how two aspects of providing incentives influence the effectiveness of using incentives to promote smoking cessation. One aspect is the criterion for providing incentives, e.g., whether to require smoking cessation before providing an incentive or to provide incentives following smoking reductions. The other aspect being investigated is whether it is best to use a fixed incentive amount or an amount that increases with continued cessation success.

What is being measured

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

  1. Breath Carbon Monoxide Levels Indicating Smoking Abstinence During the Study, i.e., the Number of Breath Samples With Carbon Monoxide (CO) Levels Less Than 3 Parts Per Million (Ppm)

    Measured: daily for breath CO

Secondary outcomes (1)
  1. Average Number Cigarettes Reported Smoked Each Day in the Past Week Measured at Follow-up Six Months After Entry Into the Study

    average number cigarettes reported smoked each day in the past week at follow up six months after study entry

    Measured: past week at follow-up six months after study entry

Questions about this trial

What is this clinical trial studying?

A study testing Contingency Management in people with Smoking, run by The University of Texas Health Science Center at San Antonio 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?

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: finished, as of the sponsor's last update on 21 Jun 2012. 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?

Yes. Results are posted in the registry (first posted 7 Jun 2012). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Breath Carbon Monoxide Levels Indicating Smoking Abstinence During the Study, i.e., the Number of Breath Samples With Carbon Monoxide (CO) Levels Less Than 3 Parts Per Million (Ppm) (time frame: daily for breath CO). 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 21 Jun 2012.
