Quit Smoking Text Message Study

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.

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.
