Adolescents are experiencing mental health difficulties more frequently, and sharing medical information online via social media is
becoming more widespread. Peer-to-peer support has developed in self-forming online communities as a result of this. While existing
studies demonstrate the dissimilarity of informational quality in such communities, we still know very little about the communities
and behavior within them. We performed interviews with two psychologists to discuss their professional views on such communities
as well as their members. Furthermore, we used Etienne Wenger’s communities of practice theory to carry out a deductive analysis of
10 videos using a digital ethnographic approach. Our findings show that the members have a safe space where they can give and
receive support. To strengthen the positive and mitigate the negative aspects, we present three implications and future work directions.
