Background: Constructions of unaccompanied children have been researched to some extent. Concepts of the children have been studied in media and policy documents amongst others. How the children are constructed within an "everyday context", in form of an open online discussion forum and how the constructions become credible, are regarded as under-researched. Aim: The aim of the present study was to identify different discourses concerning unaccompanied children on the Flashback Forum, with regard to their rhetorical organization. Discourse is meant as a way to talk about and understand the world that constructs an object or phenomenon in a particular way. Method: To answer the aim, a discursive psychological approach was used, which focuses on how credibility and truth are created in communication. Based on a theoretical model, including the four rhetorical techniques category entitlement, empirical repertoire, consensus and extreme case formulations, it was examined how the writers at the forum created truth and responded to others' beliefs about the children. Result: The results showed that unaccompanied children are surrounded by the discourses: the adults, the children,the rapists, the special treated, the sexually vulnerable and the discourse of the biological male sex. Discourses were used in parallel in the speeches and to back up arguments at the forum. The writers used the studied rhetorical techniques to build credibility in the statements. With specific expression, facts about unaccompanied children were created.
