Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

SmokefreeTXT

Daily smokers for at least 6 months who report an interest in quitting will be randomized to receive the National Cancer Institute's SmokefreeTXT.

Group Type ACTIVE_COMPARATOR

SmokefreeTXT

Intervention Type OTHER

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.

SmokefreeTXT + smartband

Daily smokers for at least 6 months who report an interest in quitting will be randomized to receive the National Cancer Institute's SmokefreeTXT + smartband.

Group Type EXPERIMENTAL

SmokefreeTXT

Intervention Type OTHER

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.

Smartband

Intervention Type DEVICE

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.
