While globally advances have been made to recognize children as social actors in their own right, for psychiatrized young people their experiences of distress are often seen as a limitation and thus used as a justification for denying their meaningful participation in matters of concern to their lives. However, what would it mean if 'mental illness' was not seen as a 'limitation', but rather as an 'epistemological position' from which the social world is experienced, understood and acted upon? What would it mean if our theories about 'distress' and 'helping' were premised on the subjugated knowledges of psychiatrized children and youth? The consumer/survivor-led research movement has made significant gains in answering these questions for the adult, but not necessarily for the child and youth mental health field. The purpose of this article is to critically examine the significance of psychiatrized young people setting and executing their own research and, ultimately, practice agendas. Presented are the outcomes of an evaluation of a participatory action research project examining the stigma of mental illness conducted with seven psychiatrized youth, 14 to 17 years old. The outcomes suggest our roles as practitioners and researchers need to shift from being 'agents' working on behalf of to 'allies' working in solidarity with young people to change the social conditions of their marginalization. The article concludes with the limits of consumer/survivor-led research for addressing adultism and, instead, ends with a call for decolonizing children's mental health.
