Who could benefit from this research

Could help

Adults 21+ who smoke nondaily and are motivated to quit, with Android smartphone access.

Less likely to help

Adults who do not use Android devices or are not motivated to quit may not benefit from this app.

What this research studies

This project tests a behavioral treatment delivered through a smartphone app designed specifically for nondaily smokers. The SiS app uses positive psychology exercises to boost positive mood and self-identity as a nonsmoker while users work toward abstinence. The study builds on prior work showing positive affect can support quit attempts and aims to demonstrate feasibility, engagement, and abstinence rates in a real-world setting. Participants will be adults 21 and older with nondaily smoking patterns who have access to an Android device. If successful, the approach could offer a scalable, non-pharmacologic option to reduce smoking-related harms in this population.

Why it matters

Potential benefit: If successful, this app could provide nondaily smokers with an accessible, engaging tool to achieve and maintain abstinence.

How similar studies have gone: Previous trials for nondaily smoking focused on medications and showed limited efficacy; this is one of the first to test a positive-psychology–based digital intervention.
