This chapter introduces, illustrates, and analyses the finding that parent/ guardians and schools/ teachers are currently ill-equipped to support young people to make informed decisions about their engagement with health-related social media. Data shows that support from adults is welcomed by young people, but that adults require a better understanding of the complex and dynamic ways in which young people use social media. Peer-based support is also important, given young people’s contextual knowledge about social media. The case suggests that adults and peers can help young people to choose how to respond to health-related information and how to determine credible information.
