Online challenges among children and adolescents: Self-inflicted harm and social media strategies.

Challenges are in line with the risk-taking practices frequent in child and youth culture. However, online challenges take on new meanings when mediated by digital sociability. To analyze this phenomenon, 122 challenge videos in Portuguese that had been made by Brazilian children or adolescents were recovered from the YouTube platform, of which 35 were selected and transcribed. Twelve types of challenges were analyzed; all involved potential self-inflicted injuries to participants, with risks ranging from minor to lethal. The discourse analysis led to an interpretation based on the theory of self-image and ethos. Online challenges appear as a powerful communicative resource to reaffirm belonging, recognition, and audience adherence, and so constitute a media strategy adopted by youth in the construction of an Internet-mediated identity in which risk and violence are decisive devices in building a self-image capable of retaining an audience. The enunciator's body sacrifice assumes a bargaining role in this media adherence.
