Study Summary
Quitlines are efficient and cost-effective treatments for smoking cessation, yet little research has explored how to personalize and optimize quitline services for women. The goal of this project is to explore the feasibility and preliminary efficacy of a quitline intervention that considers the menstrual cycle as compared to standard care for cessation. If funded, the results of this study will directly inform future research on quitline smoking cessation interventions for premenopausal women, including a full scale clinical trial.
