About this study

Official title: Evaluating Digital Health Interventions To Promote Smoking Cessation

This project will address research gaps and advance the science of smoking cessation by conducting a randomized controlled trial of an evidence-based, population-level quit smoking text messaging program with or without a smartband.

Read the detailed description

Aim 1 of this study is to test within-treatment effects for smoking cessation. The primary outcome will be biochemically (cotinine)-confirmed 7-day point-prevalence abstinence (PPA) at end of treatment (8 weeks). Secondary outcomes will be percent days smoke-free, time to relapse, and rated treatment satisfaction.

Aim 2 of this study is to explore sex/gender differences in treatment effects for smoking cessation. Given established sex/gender differences in smoking behavior and cessation,randomization will be stratified by sex/gender and we will measure effects of sex/gender on outcomes. Effect sizes will be estimated for smoking outcomes by sex.

Outcomes will be evaluated for those who complete enrollment, defined as those who complete study onboarding.

What participants receive

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

  • SmokefreeTXTOther

    National Cancer Institute's SmokefreeTXT is a text message quit smoking program available nationally. Users sign up and choose a target quit date that is within 2 weeks of their signup date. Users receive 3-5 text messages per day for up to 2 weeks pre-quit and 6 weeks post-quit. The quit date can be reset as often as needed by the user.

  • SmartbandDevice

    A smartband that will track smoking in real-time and ask the individual to confirm/deny smoking. Participants will be asked to wear the smartband during their waking hours and to charge it overnight.

What is being measured

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

  1. Number of participants with cotinine confirmed 7-day point-prevalence abstinence (PPA) at end of treatment (8 weeks)

    7-day PPA at end of treatment with be confirmed via cotinine testing in saliva

    Measured: 8 weeks

Secondary outcomes (4)
  1. Change in cigarettes smoked per day

    Change in average number cigarettes smoked per day by self report

    Measured: baseline, 4 weeks and 8 weeks

  2. Percent days smoke-free

    Percentage of smoke-free days by self report

    Measured: up to 8 weeks

  3. Average number of days to relapse

    Relapse is defined as 7 consecutive days of smoking after quitting and will be measured using self-report or smartband detection. This will be assessed after their quit date.

    Measured: 2 weeks post quit date

  4. Treatment satisfaction assessed using the Mobile Application Rating Scale User version

    This 20-item scale uses 5-point multiple choice ratings and has 6 subscales. Scores are reported as: 1) mean app quality, which is the mean score for the 4 subscales engagement, functionality, aesthetics, information quality; 2) mean of the app subjective quality subscale, and 3) mean of the perceived impact subscale. Higher scores indicate higher app quality, higher app subjective quality, and higher perceived impact. Mean scores range 1-5, with higher scores indicate higher app quality, higher app subjective quality, and higher perceived impact.

    Measured: up to 8 weeks

Questions about this trial

What is this clinical trial studying?

A study testing SmokefreeTXT and Smartband in people with Smoking Cessation, run by Yale University 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 2 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 6 Aug 2025. 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 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?

Number of participants with cotinine confirmed 7-day point-prevalence abstinence (PPA) at end of treatment (8 weeks) (time frame: 8 weeks). 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 6 Aug 2025.
