Decídetexto: Mobile cessation support for Latino smokers. Study protocol for a randomized clinical trial.

INTRODUCTION

Latinos, the largest minority group in the U.S., experience tobacco-related disparities, including limited access to cessation resources. Evidence supports the efficacy of mobile interventions for smoking cessation, which may be greater among Latinos, the highest users of text messaging.

OBJECTIVES

To describe the methodology of a randomized clinical trial to evaluate the impact of Decídetexto, a culturally appropriate mobile smoking cessation intervention versus standard care on smoking abstinence (cotinine-verified 7-day point prevalence abstinence) at Month 6 among Latino smokers.

METHODS

Latino smokers (N = 618) will be randomized to one of two conditions: 1) Decídetexto or 2) standard of care. Decídetexto is a mobile smoking cessation intervention (available in English and Spanish) that incorporates three integrated components: 1) a tablet-based software that collects smoking-related information to develop an individualized quit plan, 2) a 24-week text messaging counseling program with interactive capabilities, and 3) pharmacotherapy support. Decídetexto follows the Social Cognitive Theory as theoretical framework. Standard of care consists of printed smoking cessation materials along with referral to telephone quitline. Participants in both groups are given access to free pharmacotherapy (nicotine patches or gum) by calling study phone number. Promotores de Salud will rely on community-based approaches and clinical settings to recruit smokers into the study. All participants will complete follow-up assessments at Week 12 and Month 6.

DISCUSSION

If successful, Decídetexto will be ready to be implemented in different community- and clinic-based settings to reduce tobacco-related disparities.
