Graphic Messages to Prevent E-Cigarette Use Among Black and Latino Adolescents

Study Overview
=================
Brief Summary
-----------------
The aim of this study is to determine if graphic messages prevent future vaping use among African American and Latino adolescents. The images have been developed in a user-design model and include four main themes: health reward, financial reward, self-efficacy, and social norms. We will assess pre- and post-exposure reactions on likelihood of future vaping among African American and Latino adolescents.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| change in percent of participants who are not susceptible to future vaping | Participants will be asked three questions. (1) Are you curious about using e-cigarettes (vaping)?; (2) Do you think that you will use e-cigarettes (vaping) in the next 12 months?; and (3) If one of your best friends were to offer you an e-cigarette, would you use it? Responses include 1= definitely not, 2= probably not, 3= probably yes, 4= definitely yes. Participants who answer Definitely not to all three questions will be categorized as not susceptible. | baseline to post intervention, approximately 1 day | 
| Mean change in susceptibility score | Participants will be asked three questions. (1) Are you curious about using e-cigarettes (vaping)?; (2) Do you think that you will use e-cigarettes (vaping) in the next 12 months?; and (3) If one of your best friends were to offer you an e-cigarette, would you use it? Responses include 1= definitely not, 2= probably not, 3= probably yes, 4= definitely yes. The scores for each question will be summed per participant and the mean change calculated comparing baseline to post intervention. | baseline to post intervention, approximately 1 day |
