Project Summary - eDecídete: Mobile Cessation Support for Latino Smokers
Latinos are less likely than non-Hispanic whites to have access to health, to have knowledge of existing
smoking cessation resources, to receive advice to stop smoking, and to participate in smoking cessation
programs. Mobile technologies can dramatically enhance the reach of effective smoking cessation
interventions. However, the reach of mobile interventions among Latinos remains minimal despite the fact that
Latinos utilize smartphones at a higher rate. The primary aim of this study is to examine the efficacy of
eDecídete (Spanish for “you can choose”), an innovative 12 week mobile smoking cessation intervention
based on this work that incorporates two elements: 1) a tablet-based e-health educational session that collects
personal smoking-related information to develop an individualized quit plan and guide automated and
interactive text messaging; and 2) a text messaging program that includes educational information, behavioral
strategies, motivational and supportive messaging, and prompts to use pharmacotherapy to support smoking
cessation. Aim 1. To evaluate the impact of the culturally accommodated eDecídete program versus
standard care on smoking abstinence at Month 6 among Latino smokers. At Month 6, smokers in
eDecídete will have significantly higher cotinine-verified 7-day point prevalence abstinence (no cigarettes in
the past 7 days) than smokers in the control arm. Aim 2. To assess therapeutic alliance, pharmacotherapy
utilization, and self-efficacy as mediators of the presumed treatment effect on cotinine-verified 7-day
smoking abstinence at Month 6 among Latino smokers. Our hypothesis is that eDecídete will have greater
efficacy for smoking cessation than standard care by increasing therapeutic alliance, utilization of
pharmacotherapy, and self-efficacy to quit. Aim 3. To conduct a process evaluation that can inform
findings and future improvements. The evaluation will assess 1) satisfaction with the program and its
components; 2) text-message system utilization patterns and common content themes in text message
interactions among eDecídete participants.
