About this study

The purpose of this record is to test whether (a) participants who receive a Web-based smokeless tobacco cessation intervention will be more likely to be abstinent than participants who do not receive this intervention, and (b) whether participants who receive a telephone quitline intervention will be more likely to be abstinent than participants who are not in a quitline intervention.

Read the detailed description

Many Americans engage in the habitual use of smokeless tobacco (ST), and many wish to quit but lack resources. There is a need for innovative, validated, and easily delivered low-cost interventions to facilitate ST cessation in this under-served population of tobacco users. In our current ChewFree study, we have developed a user-friendly, interactive Web-based intervention, and in a randomized trial we have shown this website to be more efficacious than a rigorous control condition that offered Web-based basic textual information on ST cessation. We now seek to extend this proven approach by marrying it with a quitline telephone counseling service that has been used with noteworthy success for smoking abstinence but has not yet been evaluated with ST users. Our 2 x 2 design and large sample size allow us to test both main effects - Web program, phone counseling - as well as explore planned comparisons to examine the value-added contribution of the Web-based intervention to phone counseling, and vice-versa.

This project takes advantage of the opportunity to conduct a study of two tobacco cessation interventions that are growing in use. The use of tobacco help lines is now almost ubiquitous, with more than 30 state and national services now being offered. The use of the Internet for health information and behavior change (including tobacco cessation) has been growing in popularity as well. The proposed project would be an extension of both lines of research, evaluating the relative efficacy of our Internet-based program, telephone counseling, and the combination of both.

We will use a multifaceted promotional plan to recruit more than 2,000 ST users. The recruitment plan builds on the collaborative marketing efforts of a state tobacco control organization and organized promotion through media mailings, on-line advertising, and direct mailing. Follow-up assessment data will be collected electronically via the Internet supplemented by telephone follow-up. Additional data will be derived from phone counselor notes and measures of website usage.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Web + Phone, Web Only and Phone Only in people with Tobacco Use Disorder, run by Oregon Research Institute at 2 sites 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 9 inclusion and 1 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: finished, as of the sponsor's last update on 5 Aug 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Prolonged abstinence from all tobacco (time frame: 3 months and 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00820495, which also lists 1 linked publication.

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 5 Aug 2013.
