Peer led focus groups, a qualitative social science research method, and their use with young people are examined. The paper outlines three developments that have contributed to their emergence, namely: traditional focus groups, peer education and participatory research. Drawing on a study in progress, the advantages and challenges associated with peer led focus groups are discussed. A key benefit is that the power differential between the adult researcher and the researched is removed, at least at the point of data collection, rendering peer led focus groups one of few research contexts in which young people can speak collectively with no adult present.
