What this trial studies

This study aims to create and test a typology-based intervention designed to help prevent relapse in individuals who have recently quit smoking. It involves three phases: first, a Q-sorting process to develop typology statements; second, the creation of an assessment tool and intervention protocol; and third, a pilot randomized controlled trial to evaluate the feasibility, acceptability, and preliminary efficacy of the intervention. The study will recruit participants from local smoking cessation clinics and online platforms, ensuring a diverse sample of ex-smokers. The ultimate goal is to gather evidence that could support a larger definitive trial if initial results are promising.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and above who have quit smoking for at least 7 days and have previously used conventional cigarettes.

Not a fit: Patients with unstable physical or psychological conditions, those using illicit drugs, or recent pregnancies may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could significantly improve the chances of sustained smoking cessation for recent quitters.

How similar studies have performed: While the approach is innovative, similar studies have shown promise in using tailored interventions for smoking cessation, suggesting potential for success.
