NCT06133816

Brief Summary

The primary purpose of this study evaluate if different messaging impacts response rates to a brief survey (i.e., the simplified eligibility tool) that is designed to estimate pack-year eligibility for lung cancer screening (LCS). This will help inform the best way to increase response rates to the tool in future intervention studies designed to increase LCS, and expand upon survey methodology in general.
