Randomized Clinical Trial to Test the Efficacy of a Smartphone App for Smoking Cessation for Nondaily Smokers (SiS4)
Massachusetts General Hospital
Summary
The goal of this project is to test if a new behavioral treatment for people who smoke nondaily and wish to quit works. The new treatment is a smartphone app that engages users in positive psychology exercises and gives them tested tools for quitting smoking. The positive psychology exercises help users maintain their positive emotions while they quit smoking. This app has been developed with and for people who smoke nondaily through several steps of development. The main questions it aims to answer are: * Does the smoking cessation app (SiS4) help people who smoke nondaily quit smoking? * How do people's attitudes towards smoking, their smoking urges, and their mental well-being shift when using the SiS4 app? Researchers will compare the new app to an existing app that was developed for people who smoke daily to see if the new app works better to help people who smoke nondaily quit smoking. Participants will: 1. Use a smartphone app every day for 7 weeks 2. Complete online surveys about their smoking, attitudes about smoking, withdrawal symptoms and smoking urges, app use, and mental well-being at enrollment as well as 2 weeks, 6 weeks, 3 months, 6 months and 12 months after the initially chosen quit date. If the SiS4 app works well, it would be the first evidence-based quit-smoking treatment for people who smoke nondaily.
Description
The present study is a large-scale (n=1,600) single-blind, remote, parallel, randomized clinical trial (RCT) comparing our app, the SiS app, to the NCI's smartphone app "QuitGuide". The RCT will be conducted entirely remotely, because the app is intended to be accessible to smokers nationally without need for in person contact. All participants will set a targeted smoking cessation quit date and will be instructed to use the provided app for 7 weeks, 1 week prior to and 6 weeks post-quit. Online surveys will be conducted at enrollment and follow-up occurring 2 weeks, 6 weeks, 3 months, 6 month…

Interventions
- BehavioralSmiling instead of Smoking
Participants randomized to the treatment condition will use the "Smiling instead of Smoking" (SiS) smartphone app. This app delivers and guides participants through two types of content to help them during their quit attempt: (1) positive psychology content (i.e., happiness habit-building exercises, happiness boost activity, and science-based information on the relevance of positive psychology activities) designed to help nondaily smokers maintain positive affect while they go through the process of smoking cessation; and (2) traditional behavioral smoking cessation content to guide their quit process based on US Clinical Practice Guidelines.
- BehavioralQuitGuide
Participants randomized to the control condition will use the National Cancer Institute (NCI)'s "QuitGuide" (QG) smartphone app. The QuitGuide app follows the US Clinical Practice Guidelines. The app is freely available on NCI's Smokefree.gov website, which is a recommended resource for treating smokers in the healthcare setting. The QuitGuide app is frequently used as a comparison app in smartphone app smoking cessation studies. It asks participants to set a quit day, track their mood and cravings, and log their cigarettes. It provides app users with guidance on quitting (i.e., "Learn to Quit" information), offers strategies to counter smoking triggers, and allows users to set reminders to stay smoke free (time and location based).
