Testing the mHealth App Intervention for Nondaily Smokers "SiS4"
NCT06678243 · View on ClinicalTrials.gov ↗
Study 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.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT06678243
The ClinicalTrials.gov registry entry for NCT06678243 describes a study currently listed as recruiting. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 1,600 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Massachusetts General Hospital, which has 1,948 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Smoking Cessation appearing as the primary indexed condition, and to 2 interventions — of which Smiling instead of Smoking is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT06678243 reports 1 study location spanning 1 distinct geographic area — top geographies include Massachusetts. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
