Testing the feasibility of a guided imagery tobacco cessation intervention delivered by a telephone quitline: Study protocol for a randomized controlled feasibility trial

Background: Guided imagery (GI) is an evidence-based method that uses the imagination to practice and achieve a desired outcome. Little research has focused on how GI can be delivered to smokers using remote or virtual methods, such as a telephone-based intervention. Telephone-based services for tobacco cessation (quitlines) have emerged as standard of care for tobacco cessation. However, quitlines reach only a small fraction of smokers, and men and racial/ethnic minorities are less likely to use quitlines than majority women. GI has the potential to attract under-served minority groups as well as smokers who are looking for an alternative approach to cessation. The present study is designed to test the feasibility and potential impact of a GI tobacco cessation intervention delivered by telephone. This study compares the GI intervention with a standard behavioral (SB) intervention. Methods: Participants (N = 100) are randomized to either the GI (intervention) or SB (control) condition. Each condition features a 6-week intervention in which participants work with coaches to quit tobacco. Primary outcomes are feasibility related (recruitment, retention, adherence), and secondary outcomes include cessation at 6 months post-intervention (7-day and 30-day abstinence). Discussion: A GI intervention delivered via quitline would allow for scalability and dissemination, potentially reaching a more representative group of smokers. Results from this study will determine the feasibility of delivering the GI intervention, and describe the reach of the intervention to under-represented tobacco users. If successful, our study results will guide the design and conduct of a future efficacy trial.
