Geo Smoking Study and Neural and Geospatial Examination of Smokers' Exposure to Retail Environments

• Status: Completed
• Phase: N/A
• Study type: Interventional
• Enrollment: 343 (actual)
• Sponsor: Abramson Cancer Center at Penn Medicine · Academic / Other
• Sex: All
• Age: 21 Years – 65 Years
• Healthy volunteers: Accepted

Summary

The purpose of the study is to learn more about the relationships between the brain, behavior, and natural daily exposure to particular environments, including the places where smokers regularly spend time and specific retail outlets.

Detailed description

Individual participation in this study will take place over a period of approximately 2 months. During (approximately) 6 weeks of the active study period, the participant will be asked to share their geolocation information, complete either (a) 3 online sessions (for all participants in 850796) and an optional fMRI scan (for a subset of protocol 850796) or (b) 3 in-person visits (2 of which involve getting fMRI brain scans, for protocol 822815), and complete short surveys and repeated tasks (e.g., responding to Ecological Momentary Assessment \[EMA\], using study-provided funds to make small purchases from a specified retail environment) in the weeks between visits.

Conditions

• Smoking, Tobacco
• Smoking
• Smoking, Cigarette

Interventions

Type	Name	Description
BEHAVIORAL	Tobacco retailer	Assigned to make a small (\~$3.00) purchase from a tobacco retail store(s) using a study-provided debit card during each retail environment visit
BEHAVIORAL	Non-tobacco retailer	Assigned to make a small (\~$3.00) purchase from a store that does not sell tobacco (non-tobacco retailer) using a study-provided debit card during each retail environment visit.
