What this trial studies

This clinical trial evaluates a novel smartphone application designed to assist smokers in quitting by providing tailored support through the Oklahoma Tobacco Helpline. Participants will be randomly assigned to receive either standard helpline care or enhanced support via the app, which includes daily check-ins and weekly surveys. The study aims to assess the feasibility and initial effectiveness of this technology-based intervention among underserved populations, including racial/ethnic minorities and those with low socioeconomic status. A total of 500 adult smokers will be followed for 27 weeks to measure smoking cessation outcomes.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who smoke at least 5 cigarettes per day and are willing to quit within 21 days.

Not a fit: Patients who do not own a compatible smartphone or are not interested in using technology for smoking cessation may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve smoking cessation rates among underserved populations by providing accessible and personalized support.

How similar studies have performed: Previous studies have shown promise for smartphone-based interventions in smoking cessation, indicating potential for success with this approach.
