Social Media Anti-Vaping Messages to Reduce ENDS Use Among Sexual and Gender Minority Teens

The investigators long-term goal is to reduce tobacco use and tobacco-related health disparities among SGM populations. The objective of Project SMART (Social Media Anti-Vaping Messages to Reduce ENDS Use Among Sexual and Gender Minority Teens) is to evaluate the effectiveness of an sexual gender minority (SGM) -tailored social media intervention to prevent vaping initiation among SGM youth ages 13-20 years. The investigators central hypothesis is that SGM-tailored anti-vaping social media messages will be more effective than existing non-tailored messages to prevent vaping initiation among SGM youth. The scientific premise for this work is based on principles of cultural tailoring in health communication for vulnerable populations, the Health Equity Promotion Model, and the Message Impact Framework. The investigators are developing and evaluating a social media intervention because SGM youth have a high rate of social media use and are more likely to go online for health information than non-SGM youth. Social media, moreover, are increasingly used for health promotion to address health disparities and well-being of SGM populations. The investigators will conduct rapid-cycle feedback with stakeholders including SGM organization leaders to provide input on the message design, testing, and intervention implementation to ensure feasibility and acceptability of the intervention.
