The social media intervention will consist of 7 short videos between 20-60 seconds each, filmed by a professional videographer. Videos 1) start with text asking a question or giving a title highlighting the educational topic, 2) display adolescent volunteer patient partners directly teaching self-management and transition skills, demonstrating the skills via tutorials, or presenting health education content in the style of social media trends, and 3) conclude with a written summary of take-away points. The videos will be shared to participants as a password-protected Vimeo.com playlist. If participants are more comfortable in Spanish, they will be given the option to view the videos dubbed in Spanish.

The social media intervention will be contrasted against a control condition consisting of sharing the GotTransition.org Youth and Young Adult Resources webpage: https://gottransition.org/youth-and-young-adults/. This website is a project from The National Alliance to Advance Adolescent Health. The webpage includes videos, infographics, quizzes, and frequently asked questions. Testing the social media intervention against this existing national resource will assess whether the novel intervention is relatively more acceptable or efficacious than an active comparison. If participants are more comfortable in Spanish, a prompt will be provided to them to use the website search function to locate resources in Spanish.

Participants will be prompted to explore the 7 health education videos for up to 20 minutes.
