Brief Summary

This project aims to develop an adapted and enhanced mHealth couple intervention to prevent post-partum smoking relapse.

Detailed Description

The main goal of this project is to develop, implement, and disseminate effective and sustainable interventions to prevent and reduce smoking in families over their reproductive life span. So, the purpose of this project is to adapt, enhance, and test the implementation feasibility and efficacy of an evidence-based pregnancy and postnatal smoking relapse pilot mHealth intervention. The scientific relevance of this research project is given by: 1) testing a cultural-adapted version of the iCoach mobile application for the prevention of smoking uptake after birth. 2) The cultural adaptation will be obtained based on the existing literature regarding the adaptation of preventive interventions for substance use. 3) The iCoach app intervention is enhanced with SMS-delivered content addressing the dyadic efficacy for smoking cessation aiming to improve both partners' skills to work together as a team to prevent smoking uptake after birth.

Primary Outcome Measures

Name	Time	Method
Seven-day point prevalence abstinence (PPA)	At 3 months post-birth	PPA, participants who reported 'no smoking, not even a puff' in the previous 7 days are mailed a saliva cotinine test and asked to send at least one photo of the completed test. Those with a salivary cotinine \<10 ng/mL, were considered confirmed nonsmokers.
Prolonged abstinence (PA)	At 3 months post-birth	PA was defined based on the question "Have you smoked tobacco cigarettes over the past 6 months", with PA failure determined by the answers "Yes, I smoked, but never a whole cigarette," "Yes, I smoked cigarettes, but only occasionally," or "Yes, I smoked cigarettes daily for a period (or periods) of time."
