Evaluation of the Value of Varying E-cigarette Product Characteristics Across Different Populations: A conjoint analysis of 6 product characteristics among youth and young adults

To characterize the relative importance and price utility of product attributes (flavor, packaging, nicotine formulation, warning label size, device type, price) and levels within each attribute among participants with any history of e-cigarette use or use of another tobacco product.

To evaluate whether outcomes described in Aim 1 differ between youth nonsmokers and young adult smokers. Secondary analyses will evaluate whether outcomes also differ by race/ethnicity, LGBTQ+ status, gender, frequency of e-cigarette use, history of other tobacco use, and nicotine dependence, to provide evidence regarding the impact of such features on vulnerable populations with a disproportionate share of the tobacco related disease burden.
