Abstract: As an ongoing process of dialogue, action, analysis and change, participation is an important aspect of democratic society. Not only does this mean that children and adolescents have a greater influence on decisions affecting their lives, but it also serves as representation and confirmation that they are trusted within established democratic procedures. In this paper we focus on children and adolescents involved in residential care treatment in institutions for delinquent youths. Qualitative research was carried out on the methods and level of participation of children and adolescents in the processes of help in which they are involved. Through the biographical statements given by them, analysing their thoughts and experiences, the research allows for a wider perspective and understanding of the implementation of the help processes required for the institutional treatment of children and adolescents with behavioural and emotional difficulties.
